Instituto Superior Agronomia, Universidade Técnica de Lisboa (ISA-INIA),Portugal: The XI ISSIS meeting will take place
in Oeiras, Portugal,
on September 24-27th, 2007.
It will be jointly organized and sponsored by ISA-UTL and EAN-INIA. Located
near the Atlantic Ocean, about 20 km from Lisbon,
Oeiras offers mild and pleasant weather throughout the year. In September you
can count on temperatures about 25ºC. During the meeting a field trip is
planned to Sintra, a UNESCO World Heritage Centre and there the possibility of
a post-meeting excursion (September 28-30th) to Portuguese historical villages
and natural parks. At present we have about 40 pre-registrations from many different
countries covering a large spectrum of topics, such as genetics, zoogeography,
population dynamics, biological control and host-insect interactions. There is
still time to submit proposals for contributing presentations. Updated
information is available on the web site http://www.isa.utl.pt/dppf/issis.
Further information on accommodations, registration fees, instructions for the
preparations of abstracts and excursions will be sent in the second circular
and updated on the webpage in January 2007."
HISTORY OF “THE SCALE”
Because the future of “The Scale” is not clear at this
time, I thought it might be of interest to give a brief description of its
development over the years.The first
issue came out in February 1973 and was called the “Coccidologist’s Newsletter.”The front page contained images of the cover
of a male soft scale, an adult male soft scale, a lac scale female in cross
section, 7 covers or pairs of covers of a diverse array of armored scales
including crawler covers, a crawler of an armored scale, a mystery crawler, an
adult female of Plotococcus eugeniae,
a male mealybug cocoon, a Eucalymnatus
soft scale, and an ortheziid (probably Insignorthezia
insignis).I suspect the cover was
made by John Davidson.1973 was the only
year that there were 2 issues with number 2 issued in November of 1973; I guess
I realized that each edition would take more effort, and there was limited time
for such activities.The sequence of
volumes and dates went as follows:Volume
I, February 1973 and November 1973; Volume II December 1974; Volume III ? 1975
(don’t have a copy of this to confirm this date); Volume IV March 1976; Volume V
September 1979; Volume VI February 1980; Volume VII June 1981; Volume VIII May
1982; Volume IX ? 1983 (don’t have a copy of this to confirm this date); Volume
X December 1984; Volume XI December 1985; Volume XII December 1986; Volume XIII
December 1987; Volume XIV June 1989; Volume XV July 1990; Volume XVI September
1991; Volume XVII October 1992; Volume XVIII December 1993; Volume XIX December
1994; Volume XX February 1996; Volume XXI March 1997; Volume XXII March 1998; Volume
XXIII March 1999; Volume XXIV March 2000; Volume XXV March 2001; Volume XXVI
April 2002; Volume XXVII April 2003; Volume XXVIII December 2004; Volume XXIX
December 2005; Volume XXX December 2006.The years 1977, 1978, 1988, and 1993 were missed.In 1983 there was an edict from the USDA’s Agricultural
Research Service Information Office that no “newsletters” were to be issued
without their approval.When I realized
that Information Office approval was unlikely I found a loop hole by changing
the title to “The Scale.”It no longer
qualified as a newsletter and was continued in a new form.John Davidson designed the new cover, this
time with a balance scale weighing an armored scale on one side and a soft
scale on the other.Interestingly the
weight of the two seems equal.The 1987
volume was mislabeled as XII; it should have been XIII.The first few volumes were produced with a
typewriter; I am not sure when the computer took over.The first online edition was produced in
1996.We still mail out hard copies for
those who want them, but for those who are able, we ask that they download a
copy from the SEL Coccoidea Web Page at http://www.sel.barc.usda.gov/Coccoidea/scaleframe.html.
Evelyna Danzig, Zoological
Petersburg, Russia. I am now retired,
but continue to work as before. I have finished a revision of the genus Heliococcus
Sulc of the former USSR. The manuscript contains a key and review of 27 species
that is a majority of species of the genus. Helioccocus shows a wide
diversity of morphological characters, but the presence of special crateriform
ducts and the consistency of other morphological characters suggest that it is
a natural group. Description of separate genera for certain species does not
seem correct. This revision is a continuation of the monographic work on
“Mealybugs of Russia and neighbouring territories”. For the last several years
Ilya Gavrilov helped me with this work including the revision of some difficult
groups. In 2006 the English translation of the second part of the Phenacoccus
revision was published; as usual it was in Entomol. Rev. This year the paper “A
new species of Greenisca from Russia” was also published. This summer I lived in the forest
near St. Petersburg. I was very surprised by the enormous proliferation of two
species of the genus Eriopeltis: E. stammeri Schm. and E.
lichtensteinii Sign. For many years I have visited these forests but for
the first time I see millions of females. Perhaps it is connected with the unusually
warm and dry summer.
Ilya Gavrilov, Zoological
Petersburg, Russia. I have finished the
catalogue of chromosome numbers and genetic system of scale insects of the
world. It will be published soon in Israel Journal of Entomology. Also, I have
published some taxonomic and faunistic papers, mainly on mealybugs. In
particular, I have described a new genus Nudicauda Gavrilov, 2006 with
type species Ehrhornia nigraMatesova, 1957. The new genus
differs from other mealybugs by a combination of characters but primarily in
the presence of oral rim tubular ducts with a broad flat ring and in an unusual
ovisac that opens over the posterior tergites of the female body. Also, I have
finished a review of genus Mirococcopsis Borchsenius, 1948 and I shall
send it to press soon.These and some
other revisions will be parts of the monograph “Mealybugs of Russia and neighbouring
territories” that Evelyna Danzig and I are preparing.Beginning this year Evelyna Danzig and I will
supervise a postgraduate student Irina Trapeznikova, who will prepare a PhD
thesis: “Karyosystematics and reproductive biology of mealybugs.” Irina has
already mastered methods of morphological preparation of scale insects and
preparation of chromosomes.
Michelle Leddel, retired
Century High School, Alhambra, California, USA email@example.com.After 35 years of teaching at the secondary
and adult levels, I have left my classroom, however, my interest in the study of Dactylopius spp. (cochineal scale
insects) continues at a more global level.The III International Congress on Cochineal and Other Natural
Colorants (Morelia, Michoacan,
Mexico: November, 2006),
provided two new opportunities. First, I gave a slide presentation on our
cochineal scale classroom lessons and community outreach.Secondly, I met with and sat in on workshops
and presentations by growers, artists, weavers and dyers, promoters,
scientists, and researchers that are working with the cochineal scale
insects. In this case, their work centered on the 'fine' Dactylopius coccus Costa, where as
in southern California and parts
of Arizona, I found only the
'wild' species. Earlier in the year I also gave slide presentations to
educators at the State Conference of the California Continuation Education
Association in Los Angeles, and the
Teacher Recognition Day at the California
48th District Agricultural Association in Pomona,
California. Needless to say, teachers
see the unique entomological opportunities available in the study of this
colorful scale insect. Participants at three California
teachers' agriculture conference/seminars also received our 8-page cochineal mini-book,
complete with student lessons and drawings of the insects. Brief
discussions at three cactus and succulent societies meetings/conference in Tucson
and Phoenix, Arizona,
further helped to educate cacti hobbyists about the cochineal host plant, Opuntia spp. Interpreters at Colonial
Williamsburg in Williamsburg, Virginia,
continue to discuss and display the many uses of this scale insect colorant
during the 1700 and 1800's. On display at this 'living museum' are examples of
cochineal as it was used as a natural pink coloring in liquid medicines; pink
powder for wigs; food coloring in multi-colored gelatin recipes and sugar
coated almond deserts; and as a colorant for pink book covers, yarns, and
fabrics. The John D. Rockefeller. Jr. Library also has historical
resources, used not only by the interpreters, but the general public. Finally,
as "The Scale" goes to press, the Internet indicates another book
about the Dactylopius, however, I
have not found it in the U.S.

Feedback from colleagues and users will be highly appreciated. If you discover
that a particular scale insect systematist is not included in the Directory, or
you have new information and corrections, please contact me by email During 2006 I
started to re-construct and re-activate the web-site Scale Insect Forum.Hopefully it will be placed
on the Internet at a new site in 2007. The new web-site will also include,
among various items, a Directory of Coccidologists, i.e. a list of
persons who are studying or are interested in any aspect of scale insects
studies, such as taxonomy, phylogeny, economic importance, fauna, molecular
biology, cytogenetics, life history, biological control, zoogeography, chemical
ecology, useful scale insects, and interrelationship with ants.The
entry of each person will provide his/her affiliation address, email address,
phone and fax numbers and areas of research or interest. I believe that such a
list will be very useful and helpful for scale insects students all over the
world.If you are interested in having
your name included in the Directory please contact me at .Please
forward information about Scale Insect Forum to any of colleagues, who
are involved in Scale Insect Studies.
Chris Hodgson, The National Museum of Wales, Wales, UK:This has been another busy year and most of
the projects which were underway at the time of writing last year have now
either been completed or are very close to completion: the revision of some Porphyrophora species from the Middle
East etc. with Hassan Vahedi should come out in Biological Systematics and Diversity fairly early in the New Year;
the “Review of the Margarodidae sensu
Morrison (Hemiptera: Coccoidea) and some
related taxa based on the morphology of the adult males”, co-authored with
Imre Foldi, was published in Zootaxa
in July; the morphology of all stages of Marchalina
hellenica was published in Zootaxa
earlier in the year, co-authored with Sophia Gounari; the check list of alian
insects on the Galapagos Islands and implications for conservation was
published in Conservation Biology and
Biodiversity (by C.A. Causton, S.B. Peck, B.J. Sinclair, L. Roque-Abelo,
CJHand B. Landry) in January; and
lastly, the paper on the systematic and biology of the eriococcid Calycicoccus merwie (by P.J. Gullan, JH
Giliomee, CJH and L.G. Cook) came out in African
Entomology. If readers want copies of these papers, please email me at firstname.lastname@example.org.The revision of the margarodoid genus Stigmacoccus has been completed
(co-authored by Heather Gamper, Amauri Bogo and Gillian Watson) and will
hopefully be published in the coming year.Also completed is a revision of the rhizoecine mealybugs based on adult
male morphology – which (I believe) suggests that this could be considered to
be a separate family from the Pseudococcidae – but this is not supported by
cladistic studies currently being undertaken in Davis (!!) and so I await the
outcome of their analysis, based mainly on DNA (but including my data on adult
males).The study of the margarodoid
genus Palaeococcus has come to a halt
as type specimens of the type species (P.
fuscipennis) cannot currently be located.P. fuscipennis was apparently
originally described from deciduous trees, whereas all the material currently
available from the Mediterranean is off Pinus species.If any reader has seen material off a
deciduous tree (or can suggest where I might locate specimens) I would be most
grateful.The main emphasis in the New
Year will be a redescription of the type species of South American Eriococcidae
genera (senior author Dug Miller); completion of my part of the soft scales of
Australia (with Penny Gullan); and, hopefully, a start will be made on the
immature stages of New Zealand Coccidae (senior author Rosa Henderson).I also hope to complete a review of the
non-margarodoid families based on the morphology of the adult males, which is
fairly well advanced; and perhaps to produce a more definitive phylogeny of the
Coccoidea based mainly on adult male characters.A number of other small projects are also
underway and some may come to fruition in the coming year.As before, this comes with my very grateful
thanks to The National Museum of Wales for on-going support and
facilities.And I look forward to
meeting you all in Portugal
University of California, Davis, USA
Penny Gullan: The
Gullan scale lab had a very productive year in 2006. Demian Kondo (postdoc),
Cory Unruh and Nate Hardy (PhD students) have written their own news, which you
can be read below. Penny returned from her South African sabbatical in February
via short visits to Tasmania and
then New Zealand.
In Tasmania, she collected a few
scales, especially Nothofagus- and eucalypt-feeding ones, and in New
Zealand she visited Rosa Henderson at the
NZAC. Much of the rest of 2006 was spent teaching, but Penny had a very
enjoyable research month in the summer when Lyn Cook from Australia
visited for work on several collaborative projects, including on coccids with
Demian.Penny, Lyn and Nate are working
on Nothofagus eriococcids, and Penny
and Lyn have several other scale projects in various stages of completion.Doug Williams and Penny published a small
paper on Icerya imperatae, which is a
new pest of grasses in Palau.
Doug has been working hard to complete the drawings and descriptions of all
known Protortonia species and Penny
has been helping a little. Demian and Penny have been looking at Paratachardina lac insects in order to
identify a species that has become a pest in Florida
and elsewhere. As usual, this paper has grown and Demian has been kept busy
measuring specimens and sequencing lac DNA, in addition to his coccid DNA.
Penny's former Masters student, Janie Booth, has completed her dissertation on
the phylogeny of Matsucoccus (one
small paper is published so far) and will become a mother early in 2007. Bora
Kaydan, our good colleague from Turkey,
has been here since early August working with Penny on the systematics of Ferrisia mealybugs and learning
molecular techniques from Demian, Nate and Cory. There are several new Ferrisia species, and Bora has become an
expert at discerning small differences among species and illustrating the adult
females. He returns home before Christmas, but we'll see him at ISSIS in 2007.
Xie Yingping is planning a short visit to our lab in mid December (currently he
is working with Paris Lambdin for a 6-month sabbatical).
Demian Kondo:Although it is a well-deserved retirement, it is
sad news to hear that Dug Miller will leave the US Department of
Agriculture/Smithsonian. He has been so helpful to my research, and to many
others who engage in taxonomic studies of scale insects. Without his help, my
studies in the past 10 years would have been impossible to achieve. I take this
opportunity to thank him for his great achievements in the field of coccidology
and for all his patience and help. Thank you Dug. His retirement will be a
great loss in our field of scale insect studies, but I hope he will find time
to continue working on scale insects from time to time, perhaps as a hobby or a
pastime and continue to guide the next generation of coccidologists. As for
myself, I have had and still am having the best days of my life here at UC
Davis. Soon after graduating (actually a month before graduating) on April 2003
under the supervision of Mike Williams, I came to the Penny Gullan and Peter
Cranston’s lab. Since then I have been able to dedicate full time on the
research of my favorite insects and have been able to publish on various scales
including part of my dissertation. I have learned a lot from Penny and Peter,
not only about taxonomy, but also about dedication and hard work. I thank them
for encouraging me to work on a molecular level phylogenetic study of the
family Coccidae, my favorite family of scale insects. I thank Mike Williams for
introducing me to the soft scale insects. With Lyn Cook we have been working on
coccid phylogeny for almost 3 years, and we are starting to produce some
results which we hope to publish before my post-doctoral contract expires in
September 2007. I have been working on several side projects including
revisions of a few genera of coccids and lac insects, and other small projects
which have become a hobby to me. This year has been a slow one for me in
respect to published papers. Dug keeps telling me to stop writing TPs
(pronounced “tee-pees” and meaning short papers; an abbreviation for “toilet
paper”), so I have decided to write longer papers this year. I have also been
working on a taxonomic revision of the lac insect genus Paratachardina, this has proven to be a real challenge, but one
which I’ve been enjoying. My 2 trips to Chile
in 2003 and 2006 have resulted in the description of two new interesting genera
and species of eriococcids, and I was also able to write a paper on a new
coccid genus from Africa which resulted from a trip to Ghana
Nate Hardy: I became
a doctoral candidate and a published author this year (in a Zootaxa paper with
Demian, Lyn, and Penny), describing and illustrating a new felt scale genus and
species from Chile.
I also had two additional papers accepted, one to the Australian Journal of
Entomology, describing a new genus and four new species of felt scale on Eucalyptus, and a second to Systematic
Entomology discussing the phylogenetic utility of two new nuclear protein-coding
loci for scale insect phylogenetics. I also submitted a short paper describing
a new species of Phacelococcus to The
Australian Entomologist. As mentioned above I have been working with Penny, Lyn
and Rosa Henderson on the Nothofagus
felt scale fauna, redefining the genus Madarococcus,
using a combination of morphological and molecular data, and describing a
number of new Australian species. Chris Hodgson, Nate and Penny are working
together on a subfamily level classification of the Pseudococcidae.
Cory Unruh: I
have been working hard this year to finish my PhD research on the systematics
of iceryine scale insects and expect to graduate in spring 2007.Penny and I produced a revision of the ground
pearl genus Heteromargarodes which
should be published in The Entomological Society of Washington in January,
2007. As for my dissertation research, I completed molecular labwork at the
beginning of the year and worked with Lyn Cook this summer sorting out the the
intricaces of iceryine molecular data. (Many, many thanks, again, to everyone
who provided fresh material for this study.) I am currently preparing the
results of my phylogenetic study for publication and a new classification of
the tribe.I am also revising the
iceryine species of the southwestern U.S.
and am working with the USDA to make available an interactive Lucid tool to the
species of the Iceryini. Demian Kondo and I are describing a new species of iceryine
We were very lucky to secure a loan (with Penny and Demian's hard work and help from Peter
Cranston and Dug Miller) of type material for several Icerya species from the Museu Zoologio de Sao Paolo, Brazil.
This material was extremely useful to us in identifying a new pest (Icerya genistae Hempel) from Florida
and the Caribbean.
Imre Foldi, Museum national d’Histoire
naturelle, Paris.I am mainly working on the archaeococcoid
genera to provide an illustrated generic revision and an assessment of generic
relationships based on a phylogenetic analysis of the morphology of the adult females
and immature instars.In 2006, three
works were published, i.e., two new species of the archaeococcid genera Protortonia from Ecuador, described
females and males of the unusual genus Stigmacoccus
from Brazil, including the female, cyst, and first instar-nymph, and a joint
work consisting of 250 pages with Chris Hodgson on the morphology of the adult
males of Margarodidae sensu Morrison and related taxa. We published (Foldi
& Kozàr) two new mealybug species, Cataenococcus from Brazil and Puto from Venezuela, with data on other species of mealybugs collected on one of my
collecting trips in South America. Several projects are in
preparation or at an advanced stage that probably will be published in 2007 or
2008.The generic revision of the
Monophlebidae (44 genera) is progressing well and currently includes four new
species belonging to the genera Crypticerya
and Icerya.A taxonomic review of the Afrotropical genus Aspidoproctus has been initiated; the
type species of the genus, A. pertinax, and some other adult females,
males and first instar-nymphs will be described and illustrated.This is a fascinating group that includes
very large specimens, not only long but very wide and high.I have already received material from Berlin (except the Lindinger’s species which could not
be found in the museum fur naturkunde Humboldt-Universitat), from Pretoria, from London and we have in Paris Vayssière’s material
including six of the 20 known species.Many
of the original descriptions are brief and poorly illustrated, therefore, Aspidoproctus species identifications
may be confused.In some cases, old,
sclerotized females were utilized to describe species with only external
macroscopic morphological features, and never included teneral females in slide
mounted-specimens. In spite of these difficulties, it appears that one or two
new species will be described and a key may well be provided.A revision of two small archaeococcoid
families, the Coelostomidiidae and the Steingeliidae, with descriptions of new
species, is also in progress.In groups
other than the archaeococcoids, we are working on the Eriococcidae with Ferenc
Kozár, a project on our material from South America.
of Massachusetts, Amherst, Massachusetts,
Benjamin Normark: The
central project in our laboratory continues to be molecular systematics of
armored scale insects.We are always
keen to receive specimens of any armored scale insects (ideally in 100%
ethanol) and to discuss collaborative projects.Currently four graduate students in my laboratory are working on scale
insect projects.Matthew Gruwell is
completing his dissertation research on endosymbiotic bacteria associated with
armored scale insects.Rodger
Gwiazdowski is the first author of a 2006 paper on phylogenetics and
phylogeography of beech scale (Cryptococcus
fagisuga) and his dissertation will be about the molecular phylogenetics of
sexual and parthenogenetic lineages in the Chionaspis
pinifoliae complex.Two first-year
graduate students, Jin Wu and Jeremy Andersen, are working on an expanded study
of armored scale phylogeny.I am about
to embark on an 8-month sabbatical at the University
of Queensland in Brisbane.I plan to collect lots of Australian armored
scales for our phylogenetic studies and to work with Scott O'Neill (who studies
bacterial endosymbionts of insects) and with
Matthew Gruwell, University of
Massachusetts, graduate student in Entomology
and Organismic and
Evolutionary Biology, Amherst, Massachusetts, USA.I am completing my dissertation research on
the endosymbionts of armored scale insects. In the scope of this research we
have found the primary endosymbionts of armored scales to be in the Phylum
Bacteriodetes and class Flavobacteria.We have evidence that these endosymbionts have co-speciated with their
host insects and follow strict verical transmission from mother to
offspring.We have also found a
scattered distribution of Cardinium secondary endosymbionts in the armored
scale insects and are working to understand this distribution using
phylogenetics.I plan to finish my Ph.D.
program in June of 2006 and am currently looking for post-doctoral work that
will allow me to continue investigateing scale insects and endosymbionts.
Lyn Cook, AustralianNationalUniversity, Canberra, Australia:The second half of 2006 has been a
fun, interesting and a busy time for me. During June and July I visited Penny
Gullan's lab at UCDavis to work on some collaborative projects with Penny, Nate
Hardy and Demian Kondo. An added bonus to visiting Penny at that time of year
was watching the world cup soccer at a decent time of day and escaping the cold
Canberra winter - swapping it for a
nice hot Californian summer. In August, I moved from the ANU (Canberra)
to the University of Queensland
in Brisbane to take up the insect
molecular systematics position. My new contact details are: School
of Integrative Biology, The
University of Queensland, Brisbane,
Qld, 4072, Australia.email: email@example.com
For all of September and half of October, I went on a collecting trip through
tropical eastern Australia
with Mike Crisp and David Morris from ANU. The trip was fantastic - visiting
very interesting places in rainforest and the monsoon tropics through to the
arid zone, and also finding new species (genera?) of gall-inducing eriococcids
Soo-jung Suh, National Plant Quarantine
Service(NPQS), South Korea: I've started the new
project, "taxonomic revision of the Korean armored scale insects" and
found two new species records. I wish I could add more species to the list of
Korean armored scale insects. Greg Hodges and I have written a paper on a new
record (Kuwanaspis hikosani (Kuwana)) from South Korea that will be out soon. This species was previously
reported in Korea by Paik (1978), according to ScaleNet. This is incorrect
because he only provided a key to 4 species of Kuwanaspis, including K.
hikosani, but didn’t report it
from Korea. I’ve had the opportunity to examine lots of foreign
specimens of scale insects taken in quarantine at ports of entry. I'm trying to
identify undetermined specimens of mealybugs and armored scales taken in
quarantine from New
Echeveria), Netherlands (on Crassula), Taiwan (on Cycas) etc. I am extremely grateful to Drs. Greg Hodges
and Sadao Takagi for their help.
Douglas Williams, The NaturalHistoryMuseum, London, UK: In the past
year I have been completing some short papers that I have had in mind for many
years, working mainly at home. At present, I am trying to finish a work on
Linnaeus including the scale insects he described and listing all the scale
insect literature in bibliographical form that Linnaeus cited. I am still
unable to make sense of two of his references. I have a few other papers
in press including Lichtenstein with Daniele, Pulvinaria urbicola and its synonyms, a paper with Yair on Coccus limonii Murray,Sternorrhyncha of Ascension Island, a new Conchaspis with Daniele, Asterolecaniidae
and Eriococcidae of New Caledonia, two forgotten species ofCoccus
described by Westwood with Yair, and papers on Stringaspidiotus and Furcaspis
with Dug Miller. I am working on papers on a revision of Protortonia and the Icerya
during the last month or so my eyes have deteriorated to such an extent that I
fear I may never be able to illustrate another scale insect.
Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA:
Although the curator ofthe VaTech dry
insect collections, Mr. Eric Day, provided me with the key to the building
housing the collection, unfortunately there are no Coccoidea kept, except for
displays and teaching. Also, there are no scales in the liquid collection,
curated by Dr. J. Reese Voshell. As reported in The Scale earlier, after my
retirement, the Coccoidea collections from VaTech were donated to the
USDA-ARS-SEL, with my library, also the photographs, and slides on scale workers.
- Our VaTech collections benefited from two short visits by the USDA scientist
Dr. Oliver Flint last summer.- In May, I attended the meetings of the Hungarian
Entomological Society in the building where I taught horticultural entomology
in Budapest and met a number of
old-time colleagues and friends. - While visiting in S. Slovakia
in June, also in Belgium
and Hollland in August, I have collected some pest scale insect samples. - I am
looking forward to meeting many former students and colleagues at the ESA
National Meetings in Indianapolis
in December and ISSIS in Portugal
next year. Some good family news: both grandsons are biology majors at the University
Jon Martin,The NaturalHistoryMuseum, London, UK: Curates the Sternorrhyncha collections at London's
Natural History Museum, and is appealing for scale insect field workers in the
Neotropical Region to look out for whitefly nymphs that resemble soft scale
insects.Jon is investigating a group of
neotropical whiteflies which have unusually large nymphal stages. The taxonomy
is traditionally based upon the last (4th) nymphal stage, termed a
"puparium" because a fully winged adult emerges from it. A few adults
are present in collections that exceed 8 mm in length, with one even exceeding
1 cm - but all of these are lacking any associated puparia and their taxonomic
position is highly uncertain. From field observations (a paper is in press
about this matter), Jon thinks that such large adults will have puparia that
resemble those shown in the accompanying three photographs. These are atypical
for their subfamily, developing individually (rather than in distinct colonies)
and having much reduced waxy secretions (others in the group have dense tangles
of white filaments, as in the Spiralling and Giant whiteflies). When an adult
is close to emergence, a telltale pair of reddish eyespots are usually visible
at the anterior end. The ideal is for any such large puparia to be kept in a
small container to see if an adult emerges, and to then preserve both adult and
associated empty case in alcohol. If, instead, a parasitoid or group of
hyperparasites emerge(s) that is also of interest. If puparia are found with no
signs of adult emergence, those puparia are still of interest and they can be kept
dry on the leaves. Jon expects that the puparia of the really large species
will exceed 5mm in length, but that they will be widely scattered. Mating
aggregations of large adult whiteflies are also of interest - collected into

sends thanks in advance.
Rosa Henderson, Landcare Research, Auckland, New Zealand: The two papers on gall-inducing scale insects of New Zealand finally got into print in June of this year (New Zealand
Entomologist 29). Since then I have been delving into the Eriococcidae of New
Zealand including some species established here from Australia. Penny Gullan visited my lab one hot day in February to
discuss species that feed on Nothofagus
and to give me advice on the labia of Eriococcidae. A paper describing a tiny
species with quite unusual morphology, that was collected from epiphyte mats 30
m high up native trees, is accepted for publication in the next issue of New
Zealand Entomologist. A manuscript describing some interesting genera and
species adapted to alpine wet grasslands is ready for submitting. I am ever
hopeful that the revision of New Zealand Diaspididae might get underway very
soon, especially now that I have figured out how to draw the figures electronically.
At the moment (November 2006) our summer weather is slow to arrive and keeps
yo-yoing back to cold spells, probably because of the effect of some enormous
icebergs floating off our southern coast. These apparently broke off the other
side of Antarctica in 2000 and have circled round to catch a current towards
us. This must be global warming, but it sure is cool!
Dug Miller and
Alessandra Rung, Beltsville, Maryland, USA:The
big news is that the first “edition” of ScaleNet is now available on line.It
has been nearly 12 years since Yair and I received our first grant from the
Binational Agricultural Research and Development Fund (BARD) in 1995. BARD was
an important financial force in making the project happen.Major players include the Israel
team headed by Yair Ben-Dov, the US
team headed by Dug Miller, the data base system developed by Gary Gibson and
Jennifer Read, the reference system maintained and enhanced by Karen Veilleux,
and the query system developed by Jane Laroussi of Carson & Associates. It has been a lot of hard work and headaches,
but from the comments that we hear, it was worth the effort.In Beltsville there are 2 major thrusts to
our research program. Alessandra is working on the development of a molecular
diagnostic tool to differentiate Planococcus
minor from P. citri.The COI sequence differences that she has
discovered have already been useful to the US
quarantine service (APHIS) in sorting out a quarantine problem in California.We plan to publish our results in the next
few months.Other major projects include
finishing Lucid keys for the identification of scale insects intercepted at U.
S. ports-of-entry.To date a family key, mealybug key, and soft
scale key are available on line, with a beta version of the “other scales” key currently
in draft form (see http://www.sel.barc.usda.gov/ScaleKeys/ScaleInsectsHome/ScaleInsectsOthers.html).APHIS/CPHST plans to issue a CD with all 4
keys. With my impending retirement (January
3, 2007) I am spending considerable time cleaning out the backlog
of materials that have accumulated for the past 37 years.My plan is to continue to work on
scale-insect systematics about half time, so the Miller Hotel will still be
functional and available for visits to the collection. I am hopeful that the USDA administration will
fill my position in 2007.Research that
currently is in press or near completion includes 2 armored scale papers with Doug
Williams, a paper on South American eriococcids with Chris Hodgson, and a ScaleNet-based catalog on the Diaspidinae, Leucaspidinae,
and Ulucoccinae. The Miller Hotel had a few visitors this year including Jan
and Warnia Giliomee, Benjamin Normark, Rodger Gwiazdowski, Matt Gruwell,
Peter Cranston, and Bora Kaydan.
Compiled by Karen Veilleux
Each year I have
had the opportunity to write a short message in this part of“The Scale” about Karen’s major contribution
to keeping us aware of the vast reference information that has been published
over the past year.Each time I have
felt that I haven’t given sufficient accolades for all of the energy, effort,
and devotion that she has given to this project.Karen is a special person, who quietly
manages one of the most difficult areas in the ScaleNet system, i.e., the
reference file.Through her librarian,
computer, and language skills she has added enourmously to the success of
ScaleNet for all of our benefit.Without
her I am not sure how it would have been done, but certainly not with the
accuracy that we have all come to expect. Unfortunately, Karen has decided to
end her valuable input to the ScaleNet system. I guess with my retirement it
seemed like a good time to take on new challenges.I am sure that I speak for the entire
coccidology community in wishing her well and giving our hearty thanks for a
job well done!!
2005. The effect of augmentative releases of indigenous parasitoid, Anagyrus
kamali (Hymenoptera: Encyrtidae) on populations of Maconellicoccus hirsutus
(Hemiptera: Pseudococcidae) in Egypt.
Archives of Phytopathology and Plant Protection 38(2): 129-132. Notes: The
encyrtid parasitoid Anagyrus kamali (Hymenoptera: Encyrtidae) was mass reared and
released at monthly intervals in grape orchards infested with Maconellicoccus
hirsutus (Hemiptera: Pseudococcidae) at two locations in Egypt.
Approximately 300,000 adult individuals were augmentatively released from
August 2001 to August 2002. Increases of the rate of parasitism were from 35 to
76 and from 28 to 68 in Beni-Suef and El-Minya, respectively. These results
indicate that A. kamali is an effective parasitoid in controlling M.
hirsutus on grapes in Egypt. It
is concluded that the releases of parasitoid for control of M.
hirsutus were suitable for control. However, it is essential for a
successful control programme that this parasitoid should be continually reared
and consecutively periodically released so as to attain the maximum benefit of
biological control of this pest.
2005a. Importation, colonization and establishment of Coccophagus cowperi Gir.
(Hymenoptera: Aphelinidae) on Saissetia coffeae (Walk.)
(Homoptera: Coccidae) in Egypt.
Journal of Pest
Science 78(2): 77-81. Notes: The hemispherical soft scale, Saissetia coffeae (Walker)
(Homoptera: Coccidae), is one of the most important pests attacking olive trees
During the period 2001-2003, a total of about 300,000 individuals of the
parasitoid Coccophagus cowperi Girault (Hymenoptera: Aphelinidae),
obtained from India, was
released at 35 sites for the biological control of S. coffeae on olive trees
in Egypt. The
maximum parasitism rates reached 53 and 62%, while average parasitism rates
were 17.2 and 30.8% in the Marsy Mattrouh and El-Arish locations, respectively.
These results indicate establishment of this parasitoid on this important
economic plant in Egypt.

species from Aonidiella aurantii (infesting Ficus nitida [F.
benjamina] in Sinai Peninsula, Egypt), is
described for the first time. The depository for the holotype of A.
sinaii was designated in the Plant Protection Research Institute,

83(3): 1213-1215. Notes: In September 2004, sugarcane leaves heavily infested
by the sugarcane soft scale, Pulvinaria tenuivalvata (Homoptera:
Coccidae), were collected from Qena (Nag-Hammadi), and then transferred to the
laboratory for parasitoid emergence and identification. Encarsia bifasciafacies
emerged from soft scale samples. This parasitoid is recorded for the first time
attacking its new host, P. tenuivalvata, in Egypt.
Abd-Rabou, S. &

mealybug, Maconellicoccus hirsutus (Homoptera: Pseudococcidae), in Egypt.
Egyptian Journal of Agricultural Research 83(3): 1135-1139. Notes: This study
was carried out to update the checklist of parasitoids of the pink hibiscus
mealybug, Maconellicoccus hirsutus, in Egypt.
Eight primary parasitoids and five hyperparasitoids associated with the pest
were collected. Four parasitoids and three hyperparasitoids were collected and
re-identified. The new list includes primary parasitoids (Allotropa sp., Anagyrus
kamali, Clausenia josefi, Gyranusoida indica, Leptomastidea abnormis,
Leptomastix algirica, Leptomastix nigrocoxalis, Rhopus nigiriclavus)
and hyperparasitoids (Chartocerus subaeneus, Marietta

piercing sucking insects on some roselle varieties in Egypt and
the role of amino acids concentration in infestation. Archives of
Phytopathology and Plant Protection 38(4): 245-255. Notes: The cotton aphid, Aphis
gossypii Glover was found to be the only aphid species infesting the
tested roselle varieties (Sudani, Masri and White), Hibiscus sabdariffa L.
which were cultivated in El-Kanater El-khayria (about 30 km north Cairo) as ex
situ old land. The vertical distribution of the whitefly, Bemisia
tabaci (Genn.); the leafhopper, Empoasca spp. and the pink hibiscus
mealy bug, Maconellicoccus hirsutus Green, as insect pests attacking this
crop had been studied. Moreover, certain morphological characters and amino
acids concentrations in the three varieties of roselle, were obtained. The
obtained results indicated that the experimental insect pests severely attacked
leaves of the stem nodes from the 8th to the 11th (counting from the top of the
plant), whereas whitefly were more abundant on these nodes. All tested insect
species were less abundant on the 4th stem node. This may be due to the
extensive existence of gland hairs that excrete some compound, especially
phenols, that might prevent the insects from reproducing on the leaves. The
opposite was, however, true for M. hirsutus as it did not attack
Sudani and Masri varieties but the infestation occurred at the highest level on
the White variety.

& Siddiquee, M.N.A. 2006. Response of some promising
sugarcane clones to major insect pests of sugarcane. Indian Sugar 56(3): 23-28.
Notes: A field experiment was conducted during 2003-04, in Pabna and
Thakurgaon, Bangladesh, to evaluate the response of 6 promising sugarcane
clones (I245-99, I262-99, I429-99, I433-99, I446-99 and I486-99) and 2 standard
cultivars (Isd 20 and Isd 32) to some major insect pests. Results revealed that
early shoot borer (Chilo infuscatellus) and black beetle (Alissonotum impressicolle)
infestation ranged from 0.51 to 3.32% and 0.22 to 15.48%, respectively, among
the test clones/cultivars. Top shoot borer (Scirpophaga excerptalis)
and stem borer (Chilo tumidicostalis) infestation ranged from 4.55 to 53.58%
and 5.25 to 55.21%, respectively, with the highest level of infestation being
observed in clone I429-99. Rootstock borer (Emmalocera depressella [Polyocha
depressella]) infestation ranged from 6.40% (in Isd 20) to 40.55% (in
I245-99). The lowest scale insect (Melanaspis glomerata) and mealy bug
sacchari) infestation was observed in the clones I429-99 and I446-99,
respectively. White grub (Scarabaeidae) populati on ranged from 0.00 to 3.67
among the test clones/cultivars.

Amar, Z., Gottlieb, H.,
Varshavsky, L. & Iluz, D. 2005. The scarlet dye of the holy land.
Bioscience 55(12): 1080-1083. Notes: We present evidence based on chemical
analysis that identifies the scarlet dye produced by the scale insect Kermes
echinatus as the shani ("red" in Hebrew) used toward the end
of the second HolyTemple (AD
70). We know that this dye is produced by a coccoid species of scale. However,
it is not yet known which of the coccoid species was used in the Holy
Land in ancient times. Our results confirm the presence of the red
pigment kermesic acid in K. echinatus extracts. The fact that
echinatus is found in Israel
suggests that the origin of the shani color mentioned in the Bible could have
been local and that this dye was not an import from abroad, as most scholars
have assumed. Our hypothesis, backed by our long-term observations, is
supported by the color quality of kermesic acid, by the relative concentration
of the pigment, and by the prevalence of K. echinatus in Israel.

in sustainable fruit production, Skierniewice, Poland, 1-3
September 2005.] Major pests in cranberry (cv. Stevens) plantations in Latvia were
studied during 2002-05. In the eastern part of Latvia, the
cranberry tipworm (Dasineura vaccinii [D. oxycoccana]) was the main cause of yield
loss (6.2, 4.4 and 1.75 t/ha in 2002, 2003 and 2004, respectively). In the western
part of Latvia, Orgyia
antiqua was the major pest, and its population reached 9-20 larvae/m
SUP 2. In a plantation in Talsu, this pest reduced the yield by 8.0 t/ha in
2003 and by 4.0 t/ha in 2004. Other pests observed were Rhopobota naevana, Sparganothis
sulfureana, Chionaspis salicis, Lochmaea caprea and Mamestra
pisi [Lacanobia pisi].

of the entomofauna of French olive groves was conducted for 3 years to enhance
integrated pest management after providing details of the main olive pests
present in France, i.e. olive fly (Bactrocera oleae), olive moth (Prays
oleae), olive scale (Saissetia oleae) and olive psyllid (Euphyllura
olivine), and their natural enemies found around the world. The olive
scale, psyllid and moth appeared to be well regulated, the former by mass
release of the hymenopterous insect Metaphycus lounsburyi in association
with its natural enemies, the second by its natural enemies and the third by
general predators. The olive fly is more of a problem due to pest infestations
and no natural enemies, whether in conventional olive groves with integrated
pest management or in organic groves.

hellenica (GEN.) in comparison to other Mediterranean honeydew honeys.
(In Italian with summaries in English and Italian.) Italian Journal of Food
Science 18(1): 21-31. Notes: The first samples of recently produced fir
honeydew honey, obtained from Marchalina hellenica (Gennadius)
(Homoptera, Coccoidea, Margarodidae), originating from Mount Helmos in Greece
were analysed and examined on the basis of physical and chemical parameters
including humidity, acidity, sugar profile, hydroxymethylfurfural (HMF) and
diastase activity. These data were compared with five other Mediterranean
honeydew honeys of different origin obtained from the literature. Analytical
data of the Greek fir honey from M. hellenica honeydew complied with
the E.U. legal limits. The sensorial analysis indicated that the organoleptic
characteristics of this type of honeydew honey were very similar to the Greek
fir honey derived from other coccids with respect to colour, taste and smell.
The statistical analysis of the physico-chemical parameters of the six honey
types revealed two major groups. One group consisted of three Greek honeys and
the other included one Spanish and two Italian honeys. It also showed a marked
similarity between the two Greek honeys that came from M. hellenica honeydew on
either fir or pine trees.

2005. Biodiversity of indigenous tussock grassland sites in Otago, Canterbury and
the central North Island of New Zealand. I. The macro-invertebrate fauna.
Journal of the Royal Society of New
Zealand 35(3): 287-301. Notes: This contribution
introduces a short series of papers on biodiversity of indigenous tussock
grassland at four sites in New
Zealand. A survey of invertebrates of tussock
grassland sites was carried out in the summer of three successive years,
2001-03. The sites included two in Otago in snow tussock grassland at Deep
Stream and Mt Benger, a site at Cass in inland Canterbury, and
one at Tukino in the central NorthIsland.
Sampling was carried out by taking turf samples from each site, and extracting
the invertebrates with heat extractors. The invertebrates were divided into 30
major groups. This quantitative sampling method allowed the densities of
invertebrate groups to be calculated. Total macro-invertebrate density for all
sites ranged between c. 1600 and 5600 m SUP -2 . Total invertebrate abundance
was highest at the central NorthIsland
site, but this was very much dominated by Formicidae. Across all sites,
Formicidae, Coleoptera, and Pseudococcidae were consistently the most abundant

revealed that total developmental period of C. nigrita was shortest
(26.13 days) on Melanaspis glomerata (Green) when compared with Aspidiotus
destructor (Sign.) and Hemiberiesia lataniae (Signoret).
The fecundity and longevity of C. nigrita were found to be
comparatively high with maximum suitability index (2.638) when reared on M.
glomerata. Adults of C. nigrita was voracious than grub
stage and each adult required 1195.65 +/- 23.01, 1183.33 +/- 52.04, 1095 +/-
67.27 number of M. glomerata, A. destructor and H. lataniae while a total
of 244.41 +/- 4.89, 228.73 +/- 6.52 and 219.73 +/- 3.26 number of scale insects
were consumed by grub in its all four stages, respectively. Old grubs consumed
more scales than the young grubs.
2005. Overview of entomological research concerning the forest ecosystems of
the northern rim of the Mediterranean Sea.
Pages 15-22 in Lieutier, F. & Ghaioule, D. (Eds.), Entomological
Research in MediterraneanForest
Ecosystems. Versailles, France:
INRA Editions.Notes: An overview of
data concerning forest areas in the 16 countries (Portugal, Spain, France, Italy, Slovenia, Croatia, Serbia and Montenegro, Albania, Macedonia, Greece, Bulgaria, Turkey, Cyprus, Syria, Lebanon and Israel)
along the northern rim of the Mediterranean Sea is
given and indicators of insect damage are provided, whenever available. A
database has been prepared by retrieving references from the CAB database for
the period 1972-2001, for each main host plant and insect pest. Pines (Pinus)
are the most intensively studied trees, particularly because they are
vulnerable to two very important pests, the pine processionary moth (Thaumetopoea
pityocampa) and the pine bast scale (Matsucoccus feytaudi).
Among the insects that attack broadleaved trees, Lymantria dispar is by
far the most often studied. Information taken from general sources and
handbooks concerning forest insects in each country is presented and compared.
The activities of international research groups and networks focused on
Mediterranean forest entomology are summed up. Present research trends in this
field are discussed and the objectives of ongoing projects at the European as
well as the national level are presented. Finally, suggestions about future
work in this field are given.

Zealand beech forest. New
Zealand Journal of Ecology 29(1): 105-115. Notes:
We estimated the annual production of honeydew per unit land area of beech (Nothofagus
spp.) forest by measuring the amount of honeydew produced in 24 h by scale
insects (Ultracoelostoma spp.) (Hemiptera: Margarodidae) every month for
2 years. We used exclosures to prevent animals (notably Vespula wasps) removing
honeydew, and we compared the standing crop of honeydew inside permanently
closed exclosures with that outside exclosures. Honeydew production and the
number of honeydew droplets was highly variable between individual trees, tree
type, position on tree, and, exclosure type, and within and between years. The
amount of honeydew available outside exclosures was significantly reduced in
year two, predominantly by Vespula wasps, even though wasp
density was relatively low. Sugar composition also varied between tree type and
between years. Up to 5% of the sugar was glucose, with varying proportions of
fructose, sucrose and oligosaccharides. The surface area of trees infested with
scale insects was estimated using allometric regression relationships between
tree diameter and total surface area of tree trunk and branch material. These
estimates were combined with measurements of tree diameter in 10-m radius
circular plots to give a production estimate of between 3500 and 4500 kg dry
weight honeydew ha SUP -1 year SUP -1. Using this data, combined with
previously published estimates of carbon uptake, it was estimated that between
6 and 8% of net primary productivity was released as honeydew. Honeydew scale
insects provide large amounts of biologically available carbon in the form of
soluble sugar. It is a crucial resource for the above-ground system, and
probably also for the below-ground system. We conclude that scale insects have
the potential to function as keystone species in these forests.

systemic and contact action has been evaluated for use in lac ecosystem as a
substitute for the currently used conventional insecticide endosulfan. Doses
CHC viz. 0.05% 0.075% and 0.1%, tested on 2(nd) instar lac larvae reared on Butea
monosperma (palas) during rainy season crop in order to evaluate its
efficacy against Eublemma amabilis and toxicity to Lac insects. All the tested
doses proved safe to Lac insects & enabled effective control of E.
amabilis, an insect predator of lac insects.CHC 0.05% provided results at par with the
conventionally used insecticide endosulfan (0.05%) in respect of reduction in
population of E. amabilis and consequent increase in Lac crop yield. The
insecticide also exhibited safety to lac insect at all the three doses tested.

2006. Infestation rates and natural enemies of Mercetaspis halli (Green)
(Homoptera: Diaspididae) with new records from Turkey.
Gazi Entomological Research Society 8(2): 1-5. Notes: The diaspidid Mercetaspis
halli is considered as an important pest and is in the domestic
quarantine list of Turkey.
Field surveys in Turkey
during 2002-04 showed that the infestation level by the pest was low in almond
orchards. One parasitoid and 16 predators were recorded as natural enemies of M.
halli. The parasitoid Thysanus ater is recorded infesting M.
halli for the first time in Turkey.
Among the predators, Scymnus araraticus (34.26% of the
adult), Oenopia conglabata (25.56% of adults) and Adalia fasciatopunctata
revelierei (12.62% of adults) were the most common predators of M.

(Cockerell) (Hemiptera: Pseudococcidae), differ within seasons and among
regions and stages of the sugarcane crop cycle. Australian Journal of
Entomology 44(3): 304-309. Notes: The pink sugarcane mealy bug (PSMB; Saccharicoccus
sacchari) is widespread on sugarcane globally. PSMB infest above-ground
storage tissue as it develops, feeding on phloem and producing exudate. It is
not known, however, whether the level of infestations is the same in different
sugar growing regions, or how population size varies year to year within a
region. Field surveys of the number of nodes infested were conducted over five
seasons in three mill-regions in northern Australia
(Macknade, Kalamia and Marian) on plant and ratoon crops. The pattern of
infestation was very similar across seasons (only in one year of very low
rainfall was the increase in population delayed). In all three regions the
proportion of nodes infested was similar but reached the maximum one month
later in the Marian region compared with the Kalamia and Macknade regions. The
Kalamia region was distinguished by the rapid decline in the number of nodes
infested down to a very low level by March. In the Macknade region mealy bugs
persisted at higher levels than the other two regions. The PSMB infestation
started earlier and was much greater in ratoon crops than plant crops
throughout the sampling period. The differences were more pronounced in the
Macknade and Marian districts. These observations provide a firm basis from
which future strategies to control PSMB can be developed.

(Hemiptera: Coccoidea: Matsucoccidae) based on morphological and molecular
evidence. Proceedings of the Entomological Society of Washington

cause damage to pine trees, Pinus species, in the United
States and elsewhere in the Holarctic Region.
Efforts to reconstruct the phylogeny of the group have provided information on

morphological data. Matsucoccus resinosae Ben and Godwin, described from the
eastern United States, and
thumbergianae Miller and Park, from South
Korea, are considered to be new synonyms of Xylococcus
Kuwana. The taxonomic confusion surrounding these names is discussed. In
addition, we suggest that several other species of Matsucoccus, including M.
pini Green, should be investigated as possible synonyms of M.
Borer, E.T. 2006. Does adding biological detail
increase coexistence in an intraguild predation model?. Ecological Modelling
196(3-4): 447-461. Notes: Understanding coexistence is a central concern for
community ecologists. The limited combination of parameter values over which
coexistence can occur in most models of competing species suggests that
coexistence may not be a general phenomenon, yet observations of communities
demonstrate that coexistence of competitors is common. In this paper, I use a
well-studied host-parasitoid system, California red
scale and its parasitoids, to explore whether intraguild predation (IGP) is a
likely coexistence mechanism for these species and to motivate an exploration
of how the level of biological detail in theoretical models influences
conclusions about the likelihood of coexistence via IGP. Although prior work
has shown that parasitoid and host densities in the field follow the patterns
predicted by simple IGP theory, in this detailed model parameterized with
empirically derived values, coexistence is not predicted. Thus, in spite of the
concordance between field observations and simple model predictions, the current
model demonstrates that IGP is unlikely to be the sole coexistence mechanism
for the parasitoids of California red
scale. Furthermore, IGP is an equalizing coexistence mechanism, and these
results demonstrate that adding biological detail to this type of mechanism
does not substantially increase the predicted coexistence region. This
important result adds to the growing literature showing that simple models
often can capture the fundamental processes operating in more complex models
and may be sufficient to capture underlying ecological patterns. Because models
lacking system-specific details are better able to produce general conclusions,
the current result suggests that general theory maybe used to gain insights
into a diversity of ecological systems.

of aphids and scales select for different life histories in their ladybird
beetle predators. Journal of Applied Entomology 130(6/7): 356-359. Notes: Life
history parameters tend to differ between aphidophagous and coccidophagous
ladybird beetles. It seems that the nature of prey, in particular the
abundance, number and size of the colonies and their spatial distribution, may
have been selected for the evolution of the life histories in these two groups
of coccinellids, leading the aphidophagous ladybird beetles to develop at a
fast pace and the coccidophagous beetles at a slower pace. To study the
abundance, number and size of the colonies and the spatial distribution of
aphid and coccid species, 100 sampling plots regularly spaced along four
parallel transects were surveyed in the summer of 2004. At each sampling plot,
species abundance, and the number and size of colonies of aphid and coccid
species were recorded. Iwao's patchiness regression was used to assess the
spatial distribution of aphids and coccids. From this study, it was found that
coccids are much rarer than aphids but formed more colonies. Whereas aphids
display a stronger tendency to crowding, aphid colonies are randomly
distributed in space while coccid groups are aggregated. So, it seems that the
abundance and spatial distribution of prey distribution may be factors
selecting for the evolution of different life histories among aphidophagous and
coccidophagous ladybird beetles.

promising agents of biological control. This work was conducted to determine
some nutritional aspects of Ceraeochrysa cincta, using as food
larvae and eggs of butterflies: Diatraea saccharalis, Sitotroga cerealella
kuehniella [Ephestia kuehniella]. The parameters analysed were:
consumption, growth tax and predation tests with scale: Selenaspidus sp., Coccus
sp. and Orthezia sp. Based on the results, it can be concluded that:
(1) the differentiated larval feed does not show significant differences in the
periods of preoviposition, oviposition, postoviposition and fertility; (2) the
measures of cephalic capsule indicate that the differentiated feed does not
show interference in the growth tax by larvae; (3) all the diets are efficient
cincta larval development; and (4) C. cincta has potential as a
controlling agent of Selenaspidus sp. and Coccus
sp. but is inefficient against Orthezia sp.

NO. 81.] For all important crops in Morocco, key
pests are always introduced species, i.e. Aonidiella aurantii, Aleurothrixus
floccosus, Bemisia tabaci, Frankliniella occidentalis, Liriomyza bryoniae, L.
trifolii, Panonychus citri, Parlatoria blanchardii, Phyllocnistis citrella
persicae among others. The biological traits (dispersal, mode of
reproduction, immature stages and generation time, and temperature and
development) of such pests were observed to study principles underlying the
success of their entry, establishment and spread. It appears that immature
development for all species of interest occurs over a wide range of temperatures.
Such species also have short generation times, which result in overlapping
generations. Although such pests are reported as polyphagous, they show some
specialization in a Moroccan context. Natural enemies and temperature are the
most important factors in the regulation of population densities and in the
limitation of the spread of introduced species.

2006. A common mode of attraction of larvae and adults of insect predators to
the sex pheromone of their prey (Hemiptera: Matsucoccidae). Bulletin of
Entomological Research 96(2): 179-185. Notes: The attraction of several adult
predators, genera Elatophilus, Hemerobius and Sympherobius, to the sex
pheromones of pine bast scales, Matsucoccus Cockerell, has already
been demonstrated. Here, the hypothesis that the larvae of these predators are
similarly attracted to the host prey sex pheromone is tested. The response of
predators was tested in field trials using pine tree arenas baited with the sex
pheromones of M. josephi Bodenheimer et al.; Harpaz, M. feytaudi Ducasse and M.
matsumurae Kuwana. Experiments were conducted in Israel in
stands of Pinus halepensis infested by M. josephi and in Portugal in
stands of P. pinaster infested by M. feytaudi, respectively. The
selectivity of larvae for the three sex pheromones was tested in Petri dish
arenas in the laboratory. In the field, the larval stages exhibited similar
modes of attraction to those of the conspecific adults: Elatophilus hebraicus
Pericart in Aleppo pine
forest, E. crassicornis Reuter and Hemerobius stigma Stephens in the
maritime pine forests. Laboratory choice tests confirmed the kairomonal
selectivity of larvae. Both forest and laboratory tests demonstrated the response
of a coccinellid of the genus Rhyzobius to the sex pheromones of M.
feytaudi and M. matsumurae. A unique chemical
communication system among several taxa of predators of Matsucoccus spp. was
highlighted that may be attributed to their coevolution on a geological time

H. 2006. Kairomonal response of predators to three pine bast scale
sex pheromones. Journal of Chemical Ecology 32(7): 1577-1586. Notes: The
kairomonal activity of the sex pheromones of three pine bast scales, Matsucoccus
feytaudi, M. josephi, and M. matsumurae, as well as a new
analogue of the M. feytaudi sex pheromone, were investigated in pine forests of
France, Portugal, and Italy. The response of the maritime pine bast scale
predators, Elatophilus spp. and Hemerobius stigma, was used to test
the influence of trapping methods, kairomone composition, and dose. Both
predators showed significant attraction to all compounds except to the sex
pheromone of M. josephi. Significant increase in captures was observed as a
function of dose, and within the studied dose range, up to 2200 microg, no
threshold saturation limits were observed for any of the attractive compounds.
Trap design and size did not significantly influence predator captures, except
for high population levels of Elatophilus crassicornis, when plate
traps were more efficient than delta traps. Geographic variations were found in
the kairomonal responses patterns of both predators, with the M.
matsumurae sex pheromone being more attractive to the oriental
populations from Corsica and Italy,
whereas the western populations in Aquitaine and Portugal were
more attracted to the M. feytaudi sex pheromone.
2006. Internal structures of the mouthparts of Coccinea (Hemiptera:
Sternorrhyncha). Polskie Pismo Entomologiczne 75(2): 255-265. Notes: Internal
structures of the mouthparts of Coccinea were examined on the basis of
cross-section across the third segment of rostrum. The research was conducted
on representatives of 7 families: Orthezia urticae (Ortheziidae), Icerya
purchasi (Monophlebidae), Kermes quercus (Kermesidae), Greenisca
brachypodii (Eriococcidae), Pollinia pollini (Cerococcidae), Trionymus
newsteadi (Pseudococcidae) and Saissetia hemisphaerica [S. coffeae]
(Coccidae). The general model of the internal structures of the mouthparts is
closely similar in various Coccinea families. In the studied groups of scale
insect, there is one model of the inner structure of the mouthparts. Three
locks connect the maxillae: dorsal, middle and ventral. The locks consist of
various processes. Small differences in the shape of the processes in the
middle lock have been observed. The mandibles are not mirror images of each
other. In phylogenetic studies, the character of interlocking apparatus and
other internal and external structures of the mouthparts in scale insects can
be utilized in the identification of higher categories for all the Hemiptera.

Notes: The phytosanitary problems leading to lower citrus production in the
state of Rio de Janeiro (Brazil) are
due to the insufficient knowledge on insect species affecting citrus orchards.
The objective of this research was to study the geographical distribution of
phytophagous insect species associated with citrus production, in 17
municipalities of Rio de Janeiro,
from January 2000 to June 2001. The municipalities were located in 4 regions:
Baixada Fluminense (the lowland region), Regiao Serrana (the mountain region),
Regiao das Baixadas Litoradneas (the citrus-producing marshland region) and
Regiao Noroeste (the Northern region). Samples were collected from one orchard
in each municipality by means of the presence or absence methodology. Eleven
species were found in 3 municipalities and 6 species were found in 3 others.
The species Aleurothrixus floccosus and Selenaspidus articulatus
were found in 16 municipalities. Lepidosaphes beckii and Toxoptera
citricida were found in only 7 and 10 municipalities, respectively.

concentrated red-purple betacyanin food colourant from Opuntia stricta fruits.
Journal of the Science of Food and Agriculture 86(1): 122-128. Notes: A
red-purple food colourant from Opuntia stricta fruits was obtained
and studied. Four steps were involved in its isolation: washing, extraction,
centrifugation and concentration. Ethanol:water 60:40 (v/v) was selected as the
optimum extraction solvent to reduce the viscosity caused by the presence of
mucilage and pectins. The resulting 40-fold concentrated extract had a high
colour strength (3.9, OD 535nm, 1% v/v sol), a high betanin concentration (4.7
g L SUP - SUP 1) and low viscosity (59.0 cP). It also showed high stability (t
SUB 1 SUB / SUB 2 = 236.6d, 4 Degree C) mainly due to its low pH (3.4) and low
water content (571 g kg SUP - SUP 1). These characteristics were in the same
range as shown by three commercially available liquid concentrated colourants
studied (red beet, red carrot and red grape skin). The colour parameters of
this concentrated extract of Opuntia stricta were compared with
those of commercial red colourants (red beet, red carrot, red grape skin,
cochineal, elderberry, hibiscus and red cabbage). CIELAB values of Opuntia
stricta (1.5 mL L SUP - SUP 1 ) were L* = 69.8, a* = 59.7 and b* =
-23.5. Opuntia stricta presented a vivid red-purple colour which was
distinguishable from the colours shown by the other natural red food

2006. Alien insects: threats and implications for conservation of Galápagos
Islands. Annals of the Entomological Society of
America 99(1): 121-143. Notes: Alien species are the principal threat to the
conservation of the Galápagos Islands, but
little is known about the status of nonindigenous Galápagos insects and their
effects on the biota. Currently, 463 alien insect species have probably been
introduced to the Galápagos, an increase of 186 unintentional species
introductions since an inventory in 1998. Alien insects now constitute 23% of
the total insect fauna. Six species are known to be invasive and a threat to
the biota: two species of fire ant and two wasps, a scale insect, and an
ectoparasitic dipteran. The ecological impacts of the remaining species are
unknown, making the prioritization of action for conservation management
difficult. Thus, a newly developed and simple scoring system is presented to
predict their potential invasiveness based on trophic functional role,
distribution in Galápagos, and history of invasiveness elsewhere. An additional
52 species are predicted to be highly invasive. The endemic flora is most at
risk because the largest proportion (42%) of the introduced species is
herbivores. Plant populations are threatened principally by vectors of plant
disease and by phloem and leaf feeders. Introduced predators and parasitoids
(17%) may either be affecting, or have the potential to affect, the status of
terrestrial invertebrate populations. At least 10% of the species are
considered to be negligible thre01.ats to Galápagos ecosystems.

effect and potential uses, the host specificity of two parasitoid species (Anagyrus
sp. nov. nr. sinope Noyes & Menezes and Leptomastix dactylopii
Howard) (both Hymenoptera: Encyrtidae) for six mealybug species [Ferrisia
virgata (Cockerell), Phenacoccus madeirensis Green, Phenacoccus
solani Ferris, Planococcus citri (Risso), Pseudococcus
longispinus (Targioni-Tozzetti) and Pseudococcus viburni
(Signoret)] (all Hemiptera: Pseudococcidae) was studied through behavioral
observations and laboratory rearing. The selected mealybug species represent
major subfamilies and tribes of Pseudococcidae. Except for F. virgata, all mealybug
species induced examinations by Anagyrus sp. nov. nr. sinope
dactylopii. Anagyrus sp. nov. nr. sinope was specific to P.
madeirensis, which was the only mealybug species selected for
oviposition and suitable for complete development of the parasitoid. No
encapsulation of Anagyrus sp. nov. nr. sinope in P. madeirensis was
observed. Leptomastix dactylopii accepted multiple species for
oviposition, with the ranking of species preference as P. citri > P. viburni > P.
longispinus > P. solani > P. madeirensis. Only P.
citri, P. longispinus and P. viburni supported the development
dactylopii. Parasitoids developing in P. longispinus and P.
viburni suffered from high encapsulation rates, while no encapsulation
was observed when developing in P. citri. The results of this study
suggest that Anagyrus sp. nov. nr. sinope is highly host specific. Leptomastix
dactylopii, on the other hand, has a wider host range. The use of Anagyrus
sp. nov. nr. sinope in a mealybug biological control program is limited to P.
madeirensis and L. dactylopii to P.
citri. The results presented in this study also lead us to question the
accuracy of the reported host range of L. dactylopii, which include all six
mealybug species tested.

spec. nov near sinope. Entomologia Experimentalis et Applicata 121: 39-50.
Notes: The mealybug parasitoid Anagyrus sp. nov. near Sinope
(Hymenoptera: Encyrtidae) is an undescribed parasitoid of the Madeira
mealybug, Phenacoccus madeirensis Green (Homoptera: Pseudococcidae). We
investigated the preference of Anagyrus sp. nov. near sinope
for six developmental stadia (first- and second-instar nymphs, third-instar
immature females, third or fourth instar immature males, pre-reproductive adult
females, and ovipositing adult females) of P. madeirensis and the fitness
consequences of the host stage selection behavior. In the no-choice test, Anagyrus
sp. nov near sinope parasitized and completed development in all host stadia
except third-instar immature males. When all host stadia were offered
simultaneously, the parasitoids preferred third-instar immature and pre-reproductive
adult females. Dissection of the stung mealybugs revealed that the clutch size
(number of eggs per host) was approximately four and three in the third-instar
and pre-reproductive females, respectively, and one egg per first-instar nymph.
Parasitoids emerged from P. madeirensis parasitized at
third-instar or pre-reproductive adult female completed development in the
shortest duration, achieved a higher progeny survival rate, larger brood and
body size, and the lowest proportion of males. We showed that the continued
development of mealybugs had significant influence on the fitness of the
parasitoids. Although deposited as eggs in first- or second-instar nymphs,
parasitoids emerged from mummies that had attained third-instar or adult
development achieved similar progeny survival rate, brood size, body size, and
sex ratio as those parasitoids deposited and developed in third-instar or adult
mealybugs. By delaying larval development in young mealybugs, Anagyrus
sp. nov near sinope achieved higher fitness by allowing the parasitized
mealybugs to grow and accumulate body size and resources. We suggest that the
fitness consequence of host stage selection of a koinobiont parasitoid should
be evaluated on both the time of parasitism and the time of mummification.

shifts in microclimate: Important climate change implications. Soil Science
Society of America
Journal 69(6): 2049-2057. Notes: Changes in vegetation due to
drought-influenced herbivory may influence microclimate in ecosystems. In
combination with studies of insect resistant and susceptible trees, we used
long-term herbivore removal experiments with two herbivores of pinon (Pinus
edulis Endelm.) to test the general hypothesis that herbivore
alteration of plant architecture affects soil microclimate, a major driver of
ecosystem-level processes. The pinon needle scale (Matsucoccus acalyptus,
Herbert) attacks needles of juvenile trees causing them to develop an open
crown. In contrast, the stem-boring moth (Dioryctria albovittella Hulst.)
kills the terminal shoots of mature trees, causing the crown to develop a dense
form. Our studies focused on how the microclimate effects of these
architectural changes are likely to accumulate over time. Three patterns
emerged: (i) scale herbivory reduced leaf area index (LAI) of susceptible trees
by 39%, whereas moths had no effect on LAI; (ii) scale herbivory increased soil
moisture and temperature beneath susceptible trees by 35 and 26%, respectively,
whereas moths had no effect; and (iii) scale and moth herbivory decreased crown
interception of precipitation by 51 and 29%, respectively. From these results,
we conclude: (1) the magnitude of scale effects on soil moisture and
temperature is large, similar to global change scenarios, and sufficient to
drive changes in ecosystem processes. (2) The larger sizes of moth-susceptible
trees apparently buffered them from most microclimate effects of herbivory,
despite marked changes in crown architecture. (3) The phenotypic expression of
susceptibility or resistance to scale insects extends beyond plant-herbivore
interactions to the physical environment.

inspecting each plant. The dispersion indices used were: variance/mean
relationship (I), index of Morisita (I SUB delta), coefficient of Green (Cx)
and k exponent of negative binomial distribution for each sampling. The
negative binomial distribution was more representative of the frequency
distribution data of this scale in citrus, since the variance was superior to
the average in all samplings. The analysis of the aggregation index showed that
the majority of the samplings presented aggregate distribution for the scales.

carminic acid and aminocarminic acid. Biotechnic & Histochemistry 80(5/6):
201-205. Notes: Carmine is one of the few dyes currently certified by the
Biological Stain Commission that is not assayed for dye content. Existing assay
methods are complex and do not differentiate the three cochineal derivatives
carmine, carminic acid and aminocarminic acid. The latter dye is relatively new
to the food trade as an acid-stable red colorant and may eventually enter the
biological stains market. The assay proposed here is a two-step procedure using
quantitative spectrophotometric analysis at high pH (12.5-12.6) followed by a
qualitative scan of a low pH (1.90-2.10) solution. Carmine is distinct at high
pH, and the remaining dyes are easily distinguished at low pH. Four instances
of mislabeling are documented from 18 commercial products, but the mislabeled
dyes were not certified dyes. Samples from nearly all lots of carmine certified
by the Biological Stain Commission from 1920 to 2004 proved to be carmine, but
they varied widely in dye content. Batches from 1920 through the 1940s were
significantly richer in dye content. Variability has been extreme since 2000,
and most of the poorest lots have been submitted since 1990.

markers for sharpshooters [Homalodisca coagulata and Homalodisca liturata for
use in predator gut content examinations. Entomologia Experimentalis et
Applicata 119(2): 109-119. Notes: To aid in identifying key predators of Proconiini
sharpshooter species present in California, we developed and tested molecular
diagnostic markers for the glassy-winged sharpshooter, Homalodisca coagulata
(Say), and smoke-tree sharpshooter, Homalodisca liturata (Ball)
(Homoptera: Cicadellidae). Two different types of markers were compared, those
targeting single-copy sequence characterized amplified regions (SCAR) and
mitochondrial markers targeting the multicopy cytochrome oxidase subunit genes
I (COI) and II (COII). A total of six markers were developed, two SCAR and four
mitochondrial COI or COII markers. Specificity assays demonstrated that SCAR
marker HcF5/HcR7 was H. coagulata specific and HcF6/HcR9
coagulata/H. liturata specific. COI (HcCOI-F/R) and COII (HcCOII-F4/R4)
markers were H. coagulata specific, COII (G/S-COII-F/R) marker was H.
coagulata/H. liturata specific, and lastly, COII marker (Hl-COII-F/R)
liturata specific. Sensitivity assays using genomic DNA showed the COI
marker to be the most sensitive marker with a detection limit of 6 pg of DNA.
This marker was 66-fold more sensitive than marker Hl-COII-F/R that showed a
detection limit of 400 pg of DNA. In addition, the COI marker was 4.2-fold more
sensitive than the COII marker. In predator gut assays, the COI and COII
markers demonstrated significantly higher detection efficiency than the SCAR
markers. Furthermore, the COI marker demonstrated slightly higher detection
efficiency over the COII marker. Lastly, we describe the inclusion of an
internal control (28S amplification) for predation studies performing predator
gut analyses utilizing the polymerase chain reaction (PCR). This control was
critical in order to monitor reactions for PCR failures, PCR inhibitors, and
for the presence of DNA. Coccus hesperidum is mentioned in

2005. Biological control of Melanaspis obscura on oaks in
Biocontrol Dordecht 50(5): 739-749. Notes: In 1988, Encarsia aurantii
(Howard) (Hymenoptera: Aphelinidae) was introduced into northern California to
control an isolated infestation of obscure scale, Melanaspis obscura
(Comstock) (Coccoidea: Diaspididae), on native and exotic oaks (Quercus
spp.) in Sacramento's CapitolPark. By
2002, there was no longer any need for chemical control of the scale (i.e.,
complete biological control). Both parasite and host are univoltine; peak
emergence of adult parasites coincides with the peak of newly settled, first-instar
scales. Increase of the parasite and concomitant decline of the scale from 1992
to 2004 are documented for one native and one exotic oak tree. During spring of
2004, mean density of female scales (based on 100 twigs per tree) on 12
previously infested oak trees was generally low, ranging from <1 (eight
trees) to 15 (single tree) scales/twig. Mean percentage parasitization (per
twig) ranged from 30 to 85%, and was density independent (spatial context) for
each of five trees. Two refuges for the scale population were noted: some scale
crawlers settled and developed under the parental scale cover (spatial refuge)
and some female scales continued to produce crawlers into late summer and early
fall, when adult parasites were no longer available (temporal refuge). This
case illustrates how an introduction strategy (i.e., single-species release of E.
aurantii), which was derived from an analysis of the parasite guild of
the pest, was executed in the field and ultimately led to successful biological

parasite complex of Pulvinaria tenuivalvata (Newstead) (Hemiptera: Coccidae) on
sugar cane in Giza, Egypt. (In
English with summary in Arabic.) Egyptian Journal of Agricultural Research 83(1):
47-62. Notes: The seasonal variation of the parasite complex of the red-striped
soft scale, Pulvinaria tenuivalvata, in Egypt was
studied. Sugarcane leaves infested by the soft scale were collected weekly from
untreated fields in Egypt,
from September 1999 to February 2000 and from September to December in 2001 and
2002. The highest rate of parasitism was recorded in 2001 (55.8%) while during
1999-2000 and 2002 those values were 43.5 and 37%, respectively. Eight species
of primary parasitoids, i.e. Coccophagus semicircularis and Coccophagus
obscurus (new record), Metaphycus flavus, Metaphycus citricola
(new record), Microterys nietneri, Parechthrodryinus coccidiphagus (new
record), Comperia alfieri (new record) and Diversinervus elegans and
6 hyperparasitoids, i.e. Pachyneuron muscarum, Marietta leopardina
(new record) and Ablerus chionaspidis (= Ablerus greatheadi; new record), Mahencyrtus
comara (new record), Cerapterocerus mirabilis (new
record) and Cheiloneurus subsp. were identified. The ratios between primary
and secondary parasitoids collected were 99:1 (1999-2000), 94:6 (2001-2002) and
96:4 (2002-2003). Metaphycus flavus and M. citricola seem to be the most
promising parasitoids to be used as biological control agents against the
red-striped soft scale on sugarcane in Egypt. The
former species was more abundant between late-October and early-March in
1999-2000 and during mid- and late-September until mid-February in 2001-02 and
2002-03; in the same period, the most abundant hyperparasitoid was Pachyneuron
muscarum. Competition between primary parasitoid species resulted in a
decrease of Metaphycus flavus and Coccophagus semicircularis collected
during 1999-2000 to 2002-03; probably their activity was replaced by that of Metaphycus
citricola whose rate of parasitism increased from 12.5% to 31.9% in the
same period. However, the general increase of hyperparasitism recorded during
1999-2000 to 2002-03 could have played a role in the decrease of Metaphycus
flavus and Coccophagus semicircularis. In 2001-02 and 2002-03, Parechthrodryinus
coccidiphagus represented 4% of the primary parasitoids emerged. The
parasitic activity of Microterys nietneri peaked (9%) in
2001-02, opposed to 2% recorded in the 2 other seasons. Diversinervus elegans and
alfieri as well as Coccophagus obscurus emerged only in
a few numbers in different seasons. Competition between secondary parasitoids
species resulted in a general decrease of Marietta
leopardina (approximately 15%) and an increase of Pachyneuron muscarum
(10%) during the second season. Their activity was somewhat replaced by that of
subsp., who dominated in 2002-03.

red-striped soft scale insect, Pulvinaria tenuivalvata (Newstead).
(In English with summary in Arabic.) Bulletin of the National Research Centre (Cairo)
30(3): 317-324. Notes: The effect of five host plants, namely sugarcane (Saccharum
officinarum), cogon grass (Imperata cylindrical), elephant
grass (Pennisetum purpureum), sweet sorghum (Sorghum vulgare var. saccharatum)
and maize (Zea mays), on different biological aspects of the red
striped-soft scale, Pulvinaria tenuivalvata, was studied. The percentage of nymphs
that succeeded to reach the adult stage differed on the different host plants.
This percentage was maximum on sugarcane and sweet sorghum followed by cogon
grass, while the minimum was on maize. The shortest preoviposition period of
the insects was recorded on sugarcane and elephant grass plants, while the
oviposition period was about twice greater on sugarcane than on sweet sorghum.
No significant difference existed between the oviposition period on sweet
sorghum and maize. The maximum number of eggs was found on sugarcane, but the
minimum number was found on maize and sweet sorghum. Adult longevity on
sugarcane was about twice greater than that on maize, while it was one-half
that on elephant grass. Thus, sugarcane plant was more preferable to the insect
than all other tested host plants.

(Green) (Homoptera - Diaspididae), on mango trees in Egypt. (In
English with summary in Arabic.) Egyptian Journal of Agricultural Research
83(3): 1199-1212. Notes: Maskell scale, Insulaspis pallidula, is a common
scale insect on mango trees, Mangifera indica, resulting in
defoliation and branch drying. Population dynamics, number and duration of
generations as well as the effect of two weather factors on the insect activity
were studied at El-Qanater El-Khairia, Qalubia
Governorate, Egypt in
2001/02 and 2002/03. Results revealed that pre-adult and adult populations
peaked four times per year during May, July, September/October and November.
The pest had four annual overlapping generations, with the highest generation
occurring during autumn in both studied years. The daily mean temperature was
entirely under the optimum range of pre-adult and adult activities in the two
years, whereas the daily mean relative humidity was within the optimum range of
the pre-adult and adult activities in 2001/02 and entirely under the optimum
range of the pre-adult and adult activities in 2002/03. The combined effect of
the two weather factors on the pre-adult and adult activities was highly
significant in both years.

of some pesticides for controlling Pulvinaria tenuivalvata (Newstead)
(Homoptera: Coccidae) on sugarcane in Kom Ombo District, Aswan
governorate. (In English with summary in Arabic.) Egyptian Journal of
Agricultural Research 83(4): 1669-1679. Notes: An experiment was conducted in
Kom Ombo district, Aswan
during 2002 and 2003 to evaluate the efficacy of Chalinger (chlorfenapyr),
Admiral (pyriproxyfen), Mospilan (acetamiprid), Actara (thiamethoxam), Marshal
(carbosulfan), Orion (alanycarb) and Sulfer (sulfer) to control sugarcane soft
scale, Pulvinaria tenuivalvata, infesting sugarcane fields. The
pesticides were highly effective against insect populations in both years.
Chalinger was the highest most effective compound against the nymphal
populations (94.8%). Admiral and Mospilan came in the 2nd order (93.6 and
93.4%) followed by Marshal in the 3rd order (88.9%). Sulfer and Actara came in
the 4th order (88.1% & 88%) and Orion was the last (86.8%). The efficacy of
the evaluated pesticides on the adult populations showed that Chalinger,
Admiral and Mospilan were the highest effective compounds on the adult
populations (93.5, 92.5 and 91.9%) followed by Marshal in the 2nd order
(86.6%). Sulfer, Actara and Orion were less effective pesticides on the adult
populations (85.6, 84.6 and 83.5%). The efficiency of the tested pesticides on
the insect populations (nymphs and adults) indicates that, Chalinger was the
highest effective compound (94.6%) on the insect populations followed by
Admiral and Mospilan in the 2nd order (93.4 and 93.1%). Marshal and Sulfer came
in the 3rd order (88.2 and 87.7%), Orion was the last (86.6%).

sugarcane in Naga-Hammadi District, Qena governorate. (In English with summary
in Arabic.) Egyptian Journal of Agricultural Research 83(4): 1649-1661. Notes:
An experiment was conducted in Naga-Hammadi district, Egypt, during 4 September
2002 and 15 September 2003 to evaluate the efficiency of Actellic 50% EC
(pirimiphos-methyl), Sumithion 50% EC (fenitrothion), Malathion 57% EC
(malathion), Malatox 50% WP (malathion), Dimethoate 40% EC (dimethoate) and
Dursban 48% EC (chlorpyrifos) for the control of Pulvinaria tenuivalvata.
The insecticides were highly effective against the insect populations in both
2002 and 2003. Actellic was the highest effective compound (99.1%) on the
nymphal populations followed by Sumithion in the second order (98.4%). Dursban
came in the third order (96.9%). Dimethoate, Malatox and Malathion came in the
last order (96.1, 96 and 95.7%). Similar results were observed with the adult
populations where the highest effective compound was Actellic (96.9%) followed
by Sumithion and Dursban in the 2nd order (95.8 and 95.2%). Malatox, Dimethoate
and Malathion came in the last order (93.3, 93.2 and 93%). On the other hand,
the efficiency of the tested insecticides on insect populations (nymphs and
adults) combined over the 2 years indicated that, Actellic was the highest
effective compound (98.7%) followed by Sumithion in the 2nd order (98.2%) and
Dursban in the 3rd order (96.4%). Dimethoate, Malatox and Malathion came in the
last order (95.8, 95.4 and 95.3%).

2006. Temporal and spatial characterization of an infestation of Paratachardina
lobata lobata (Hemiptera: Kerriidae), a new invasive pest in Florida. (In
English with summary in Spanish.) Florida
Entomologist 89(3): 367-374. Notes: The lobate lac scale, Paratachardina lobata lobata
(Chamberlin) was first found in south Florida in
1999. Reported hosts are present in the germplasm collection located at the
USDA/ARS Subtropical Horticulture Research Station in Miami, and
the scale was first found there in the summer of 2002. A study was initiated to
determine the spatio-temporal dynamics of a lobate lac scale infestation at
SHRS from Jul 2003 to Jul 2005. Numbers and percentages of viable adults, and
reproductive success as indicated by ratio of nymphs to viable adults (<2 cm
diam and 30 cm long branch
sample) were recorded. There were 55 plants evaluated over the 80 hectares
study site. Infestation increased from 42% of sampled plants at the start of
the study to 75% at the end, and most of the plants had low or moderate levels
of infestation (between 0 and 100 adults per 30 cm branch) over the course of
the study. Percentage of non-viable adults dropped from 27% at the start of the
study to 7% by the end of the study, and ratio of nymphs to viable adults
dropped from 9% to 2%. Spatial analysis showed that initial infestations were
along the eastern edge of the sampled area, with populations declining over the
first half of the study but then increasing during the second half. Over the
course of the study, heavy infestations (>=100 scales per 30 cm branch) were
found on only seven host plants. Among plants located in areas of high
infestation probabilities, individual host susceptibility appeared to be the
primary factor regulating infestation level.

in Sao Paulo
state, Brazil. It
causes debility of the trees and drop of leaves and fruits. The purpose of this
study was to evaluate different types of insecticides (contact, systemic and
insect growth regulator), including aldicarb, imidacloprid, deltamethrin,
ethion, thiamethoxam, acephate, fenpropathrin, pyriproxifen and mineral oil,
for the control of O. praelonga on 'Pera' sweet orange grafted on 'Cleopatra'
mandarin. The evaluations were performed on four branches per plant, by
quantifying the number of nymphs and adults. The number of insects present per
tree, in five leaves randomly sampled, was also evaluated. All the insecticides
were efficient against O. praelonga scale for 288 days.

Research 19(3): 284-288. Notes: An experiment was conducted to investigate the
anti-mutation of white wax scale (Ericerus pela) and to analyse its
main functional factors. The micro-nucleoli rates in every experimental dose
were lower compared with the contrast in 48 h. Significant difference was
observed between high dose and contrast group. The restriction rate of
micro-nucleoli in high dose group was 34.19%. Results showed that white wax
scale could restrict mutation caused by CP [coat protein] and had clear
anti-mutation function. White wax scale contained 2.14% chitin and 7.2% crude
polysaccharide. The polysaccharide content was 4.54% after removing protein by
enzyme. The sugar content of the polysaccharide was 22.1% as glucose, composed
of glucose, galactose and fructose in molar ratio of 5:21:1. The polysaccharide
isolated from white wax scale was polysaccharide-protein complex. This insect
contained 1.3% flavonoid and several kinds of vitamins, chitin, polysaccharide.
Vitamin and flavonoid were the main anti-mutation functional factors of white

tests of white wax scale in specific and unspecific immunity. The result showed
that the IgM in high dose group was clearly higher than that of the control in
serolysin test. Lymphocyte transformation and propagation in mice were notable
in high dose group. The results of carbon clearance test in mice and the weight
of immune organ test (unspecific immune tests) were negative. The research
results showed that white wax scale could increase the specific humoral and
cell immunity ability. Therefore white wax scale has immunodulation function
which could be developed and utilized as health food resource.

a butcher: Analysis of the literature on allergy to carmine. International
Archives of Allergy and Immunology 138(3): 243-250. Notes: Hypersensitivity to
carmine (E120) has been identified as a cause of food intolerance and
occupational asthma. We present a case of occupational asthma following
exposure to carmine in a manufacturer of sausages and review the literature.
Case Report: A 42-year-old non-atopic male presented with a 5-year history of
rhinoconjunctivitis and asthma on occupational exposure to food additive dusts.
Symptoms increased after work. The patient had been exposed for more than 20
years. Methods: Skin prick tests were performed with a battery of common
inhalant allergens and spices. Cochineal, carmine lake and additive mixes used
by the patient were extracted and subsequently used for skin prick test,
bronchial provocation and in vitro measurements (specific IgE, Western blot and
chromatographic fractionation). Results: Prick tests were positive to carmine
and carmine-containing additives; carmine-specific IgE and bronchial challenge
tests were also positive (PC SUB 2 SUB 0 = 0.0004 mg/ml and 1.6 kU/I). Western
blot showed IgE binding to bands of about 30 kDa on cochineal extract and a
diffuse pattern at 40-97 kDa on carmine. This result was confirmed by gel
filtration chromatography and dot blot. Carmine completely inhibited IgE
binding to cochineal extract. Discussion: Carmine is a potential sensitizer in
an occupational setting: 18 cases of occupational asthma have been described to
date. Carmine allergens are poorly defined; in general, proteins from cochineal
not removed by the extraction process are considered as the main allergens in
carmine. Our results are consistent with this, but show that these proteins may
be subject to chemical modification.

Revista Mexicana de Biodiversidad 77(1): 97-102. Notes: Wild cochineal has
characteristics that offer advantage as a source of carmine and for fine
cochineal improvement. To characterize wild cochineal, we initiated a breeding
effort raising wild cochineal from the arid zone of the north of Mexico,
using as a host organism Opuntia megacantha Salm Dyck. The
results indicate that the wild species is Dactylopius opuntiae. The presence
of parthenogenesis in females was determined. The duration of ontogenetic
stages depends on the sex of the insect. The adult female lasted 38.4 days and
4.2 days for males; the first stage nymphs were similar in duration (18-19.8
days). The complete biological cycle of the females was 77 days, and in the
males 43 days. A period of preoviposition of 18.8 days for the females was
found, laying eggs during 2 1 days with an average of 13 1 insects per female.
The sex ratio female: male was 1:1. The reproduction generally was sexual
although there were parthenogenetic females. This is the first report of Dactylopius
opuntiae as a source of wild cochineal in the arid zone of North.

2006. Irradiation as a phytosanitary treatment for Aspidiotus destructor
(Homoptera: Diaspididae). Journal of Economic Entomology 99(4): 1138-1142.
Notes: Coconut scale, Aspidiotus destructor Signoret
(Homoptera: Diaspididae), is a quarantine pest of banana (Musa spp.) and many
tropical crops. Irradiation was examined as a potential phytosanitary treatment
to control coconut scale. Dose-response tests were conducted with second-stage
nymphs, adult females without eggs, and adult females with eggs at a series of
irradiation doses between 60 and 200 Gy to determine the most tolerant stage.
The adult female with eggs was the most tolerant stage. In large-scale
validation tests and dose-response tests, a total of 32,716 adult female scales
with eggs irradiated with doses between 100 and 150 Gy produced no F SUB 1
adults with eggs. Irradiation treatment with a minimum absorbed dose of 150 Gy
should provide quarantine security for coconut scale on exported commodities.

efficacy of horticultural oil for control of Chionaspis heterophyllae
(Homoptera: Diaspididae) on Christmas tree plantations. Journal of Economic
Entomology 98(5): 1603-1613. Notes: Pine needle scale, Chionaspis pinifoliae
(Fitch), and C. heterophyllae Cooley are important pests of Scots pine, Pinus
sylvestris L., and other conifers in much of North
America. On Christmas tree plantations, these
insects are typically controlled by spraying broad-spectrum insecticides when
the vulnerable immature stages are present. However, effective control of
bivoltine populations can be difficult to achieve due to asynchronous hatch and
development of the second generation. Our objectives were to 1) determine the
phenology of the second generation of C. heterophyllae in Michigan; 2)
characterize the natural enemy complex; and 3) assess the effectiveness of
horticultural oil for control of C. heterophyllae on P.
sylvestris Christmas tree plantations. We monitored scale populations
in three counties in lower Michigan for 3 yr. Scale phenology was consistently
associated with cumulative degree-days base 10 degrees C (DD10 degrees C).
Second-generation egg hatch began at approximate to 1230-1300 DD10 degrees C,
and continued for approximate to 3 wk. The peak of the second instar coincided
with 1500-1600 DD10 degrees C. Common predators included the coccinellids Chilocorus
stigma (Say) and Microweisia misella (LeConte). On
average, 70% of the C. heterophyllae population in unsprayed fields was killed by
predators in 1999. Two endoparasitic wasps, Encarsia bella Gahan and Marietta
mexicana Howard (Hymenoptera: Aphelinidae), also were recovered. In 2000
and 2001, we applied a highly refined horticultural spray oil with a backpack
mist blower at 1500-1600 DD10 degrees C. Scale mortality on trees treated with
oil ranged from 66 to 80% and was similar to control achieved using
conventional insecticides in both years.

Field experiments were conducted in apple orchards in North
Bohemia, from 1996 to 1999 and South
Republic, from 1996 to 2003, to
test 3 pheromone components for monitoring males of the San Jose scale, Diaspidiotus
perniciosus (SJS). The combination of 2 specific pheromone components
were the most effective for trapping SJS males. The date on which the first
generation crawlers start to migrate was determined according to the sum of
effective temperatures from 350 to 400(deg)C above 7.3(deg)C, calculated as
from the date on which the first males of the owerwintering generation have
been found in the pheromone traps. This sum of effective temperatures indicated
the optimum period for timing of insecticide application. In orchards where
insecticides were applied against the crawlers, the population density of SJS
decreased and the damage to fruits was eliminated.

major pest and their crop productivity. Acta Horticulturae 686: 377-384. Notes:
[Proceedings of the Sixth International Congress on Hazelnut, Tarragona-Reus, Spain,
14-18 June, 2004.] Studies were conducted during 1999-2003 in a 2.5-ha hazelnut
orchard at Konskowola, central-eastern Poland to evaluate the susceptibility of
large-fruited cultivars (Wonder from Bollwiller, Purple Filbert, Barram White
Filbert, Hall's Giant, Luizen Zellernuss and Mogul-Nuss) to filbert bigmite (Phytoptus
avellanae), filbert aphid (Myzocallis coryli) and lecanium
scale (Parthenolecanium corni) and their yield. Purple Filbert, White
Filbert, Hall's Giant, Luizen Zellernuss and Mogul-Nuss showed partial
resistance to two of the three examined pests. Wonder from Bollwiller and Barra
turned out to be the most susceptible to all three pests. The highest nut
yields were obtained from trees that were most susceptible to the occurrence of
the studied pests. Luizen Zellernuss was characterized by its high resistance
to filbert bigmite and lecanium scale with relatively high yield.

of the IlawaLakelandLandscapePark.].
(In Polish with summary in English.) A KertPolskie Towarzystwo Lesne 149(6):
34-39. Notes: One of the reasons of declining beech (Fagus sylvatica stands in
the presence of the scale insect Cryptococcus fagisuga which graze in
bark fissures on tree trunk, branches and roots. This insect may cause mucus
secretion from spots on the bark, bark necrosis and may open the way for the
infection of the fungus Nectria. A study was conducted at
the IlawaLakelandLandscapePark in
2004 to assess the intensity of infestation of C. fagisuga on beech by
determining the percentage of beech trees infested with C. fagisuga. It was found
that 91% of the 500 beech trees randomly selected were found to be infested
fagisuga. Trees were divided into 3 classes (low, moderate, and high)
based on the degree of infection, where 84.2 12.5 and 3.3% of the total number
of trees evaluated had low, moderate and high level of infestation,
respectively. The insect colony structure for each class was either dispersed
or cluster. Increased intensity of infestation was associated with the increased
number of cluster colonies. Incidental distribution was noted for trees with
the lowest degree of infestation, where insects were found in great dispersion.
There were only 15 beech trees found which were greatly infested with the
insects, their presence may nevertheless pose a threat to the viability of the
remaining trees in the stand. Common beech is the dominant species in the tree
stands in the park, and this may favour pest dispersal and further increase in
their population. Thus, the monitoring of the stands and the removal of trees
heavily infested with C. fagisuga should be initiated.
Neighbouring trees resistant to infestation may become a valuable material for
cloning and reintroduction in the future. The preservation of the seeds from these
trees should also be considered.

2005. Spray programme effective against Florida red
scale. Biosecurity 61: 17. Notes: In early 2004, the citrus pest Florida red
scale, Chrysomphalus aonidum, was detected at Auckland City Council's
Domain Nursery (New Zealand)
following a chance discovery by a Landcare Research scientist. Subsequent
investigations also uncovered the scale in both the tropical and temperate
houses in the Auckland Domain. The infestation was linked to recent
importations of Dracaena marginata, a popular indoor plant. Biosecurity New Zealand
instituted containment procedures to prevent further spread of this scale, and
conducted further surveys in the areas surrounding the infected site. These
measures included a spray programme using chemicals with different modes of
action and targeting both the mobile crawler and the immobile stages of the
scale. Subsequent examinations showed that these treatments were effective with
no live scale being detected. The affected site was placed under a Restricted
Place Notice, preventing the removal of risk material without appropriate
measures being taken. In conjunction with the containment procedures,
Biosecurity New Zealand
prepared and distributed a fact sheet to members of the Nursery and Garden
Industry Association. This initiative resulted in the detection of Florida red
scale on several Dracaena plants in retail nurseries. These plants were treated
with insecticide to kill any scale that were present and then destroyed. In
light of the risk posed by Florida red
scale on imported Dracaena, Biosecurity New Zealand
amended the Nursery Stock Import Health Standard to prevent further incursions
of this pest. The management of the scale infestation was then transferred to
the Auckland City Council which has continued the application of systemic
insecticides to target any scale that may be living in areas not readily
accessible by conventional sprays. To date, Biosecurity New Zealand's
on-going surveillance at the site has not detected any live scales.

combination with the use of the natural enemies present in the area, by means
of the immediate deposit of the cut material inside drums, which have been
applied an adherent layer of 20cm in the internal and external faces of its
superior border, in order to impede the exit of the apterous phases of the
hibiscus pink mealybug and the associate ants, and to allow the exit of the
natural enemies (parasitoids and predators) presents. 5 infestation levels were
set for the cayena plants: healthy, light, medium, strong and very strong;
before applying the treatment, the state of the total 112 plants were: 10.8%
medium, 44.6% strong and 44.6% very strong. After applying the treatment in two
opportunities (February 2002 and September 2002) it was possible to increase in
63.2% the presence of healthy plants, it increased to 13.3% the plants with
light attacks and in 1.4% the plants with level of medium attack; on the other
hand the plants with strong and very strong attacks diminished in 36.4% and
41.5%, respectively. Anagyrus, Apoanagyrus, Encyrtus, and
were the more abundant parasitoids found in this study, while Cryptolaemus
montrouzieri Mulsant was found in smaller number.

& Goncalves 2004 (Hemiptera Coccoidea Eriococcidae) influences gall
morphology on Rollinia laurifolia Schltdl. (Annonaceae). Tropical Zoology
18(2): 161-169. Notes: The male and female of Pseudotectococcus rolliniae
Hodgson & Goncalves 2004 induce leaf galls on Rollinia laurifolia
Schltdl. The galls occur in similar proportions but are morphologically
distinct. This study recorded the occurrence and characterized both
morphologically and morphometrically the galls on R. laurifolia. In
addition, we evaluated the impact of galls induced by P. rolliniae males and
females on the differentiation of the host plant leaf tissues. Galls induced by
females were spherical, with an average volume of 36.5 mm SUP 3 (+/-16.9),
whereas galls induced by males were conical with an average volume of 3.5 mm
SUP 3 (+/-2.6). Most of the sampled leaves were galled (93.8%). The presence of
more than 5 galls per leaf caused the leaf area to be reduced on average by
57.3% compared with ungalled leaves. Leaves with the majority of galls induced
by females had a greater area reduction than leaves with the majority of galls
induced by males. The reduction of leaf area was directly related to the
translocation of photoassimilates to gall sites and their utilization for gall growth.
The longer life cycle of the P. rolliniae female and its sessile
habit may determine the higher differentiation of leaf tissues involved in the
larger growth of these galls.

gloverii (Pack.) and its natural enemies were studied on Valencia
orange in Cuba.
Shoots were examined at each cardinal point in three strata of the trees. L.
gloverii developmental stages were counted on both upper and lower leaf
surfaces and the incidence of biological agents was registered. The biology of L.
gloverii was studied on citrus nursery of Persian lime, Eureka
lemon and Valencia
orange. A complex of parasitoids, predators and pathogens was found, which
differed among microhabitats. Populations were aggregated, and densities were
higher at the northwest of the grove, at the north of the tree, in the middle
part of a shoot and on the upper leaf surface.

ananatis Gahan (Hymenoptera: Encyrtidae), a parasitoid of Dysmicoccus
brevipes (Cockerell) (Hemiptera: Pseudococcidae). Biological Control
35(2): 93-103. Notes: The encyrtid Anagyrus ananatis Gahan preferred to
parasitize adult females of pink pineapple mealybug (PPM), Dysmicoccus brevipes
(Cockerell), compared to gray pineapple mealybug (GPM), Dysmicoccus neobrevipes
Beardsley. When given a choice of PPM life stages, adult female PPM were
preferred. Over its adult life, A. ananatis parasitized 27.7
(+/-2.5) mealybugs, with a range of 11-51 parasitized mealybugs. Development
(eggs to adult) required 23.3 (+/-0.6) and 21.2 (+/-0.8) days for females and
males, respectively, at 26(deg)C. Adult females had a mean longevity of 9.8
(+/-2.0) days, while males lived for a mean of 10.8 (+/-0.6) days at 26(deg)C
when only provided a 50% honey-water solution. Adult longevity increased to
greater than 26 days when pure honey and water were provided. Parasitoid adults
allowed access to honey lived almost sixfold longer than those denied honey.
Pure honey increased mean adult longevity almost 90 and 40% compared to water
only or diluted honey concentrations, respectively. Starvation significantly
reduced parasitoid survival and longevity with 52% of test individuals dying
after being deprived honey and water for 48 h. A. ananatis only
parasitized PPM during photophase. A. ananatis parasitized
significantly more mealybug hosts as PPM densities increased from 1 to 10
individuals per experimental unit, but then plateaued at densities above 10

(Hemiptera: Coccoidea, Margarodidae) in relation to honeydew flow. Journal of
apicultural research 45(1): 8-12. Notes: Pine honey is produced widely in Greece and Turkey and
represents almost 60-65% of the annual honey production in Greece. It
is made from the honeydew eliminated by the scale insect Marchalina hellenica when
feeding on Pinus halepensis (allepo pine) and P. brutia (calabrian
pine). M. hellenica has one generation a year, with the adult females
appearing on trees at the end of March or in April, depending on temperatures
in February and March. Female M. hellenica have 3 nymphal instars,
but the adult females have no mouthparts and do not feed. There are 3 periods
of honeydew production which can exploited by bees: in early spring, coinciding
with the spring feeding period of the third instar (which can last from 20 to
40 days depending on weather conditions); in August and September when the late
1st instar nymphs are feeding; and in October and November when the second
instars are feeding and which can last from 15 to 30 days. Although honeydew
appears in small quantities from the end of June, it does not become sufficient
for exploitation until early autumn. The 3 periods of moult coincide with 3
periods of reduced honeydew production. In recent years the quantity of
honeydew has become unreliable, causing concern to beekeepers. The reasons for
this unreliability are unknown. The present paper presents almost 3 years of
data on the phenology of M. hellenica, with observations on
the production of honeydew at each stage of development.
2006. New developments in the San
citrus IPM program. Bulletin OILB/SROP (Sect. Reg. Ouest Palearctique) 29(3):
5-14. Notes: [International Conference on Integrated Control in Citrus Fruit
Crops. Proceedings of the meeting of the International Organization for
Biological and Integrated Control of Noxious Animals and Plants, West
Palearctic Regional Section (IOBC/WPRS) Working Group, Lisbon, Portugal, 26-27
September 2005.] The majority of citrus, primarily Navels and Valencias for
fresh market, is now grown in the central San Joaquin Valley of California,
USA. In the late 1990s, a number of new insecticides (pyrethroids, insect
growth regulators, neonicotinoids, and fermentation products) were registered
for control of citrus pests. These insecticides have improved worker safety,
reduced environmental effects, and improved the survival of some natural
enemies by greatly reducing organophosphate and carbamate usage. There are,
however, some problems with integrating these new insecticides into the California
citrus pest management programme. Firstly, the two most commonly used
insecticides, pyriproxyfen for California red
scale (Aonidiella aurantii) control and spinosad for citrus thrips (Scirtothrips
citri) control, are highly selective for these two pests. Secondly,
many of the new insecticides are toxic to the predatory vedalia beetle (Rodolia
cardinalis). Thus, cottony cushion scale (Icerya purchasi) problems
have increased. Finally, exotic pests continue to invade the region, for
example, glassy-winged sharpshooter (Homalodisca coagulata), citrus
peelminer (Marmara gulosa) and citrus leafminer (Phyllocnistis citrella).
These pests require the development of management tactics that must be
integrated into the existing IPM programme. The use of more selective
insecticides, the toxicity of new insecticides to coccinellids, and the
invasion of new pests has increased the complexity of the IPM programme for San
Lee, J.E., Stewart, J.R. & Olsen, K.D. 2006. Role of two
insect growth regulators in integrated pest management of citrus scales.
Journal of Economic Entomology 99(3): 733-744. Notes: Portions of two
commercial citrus orchards were treated for two consecutive years with
buprofezin or three consecutive years with pyriproxyfen in a replicated plot
design to determine the long-term impact of these insect growth regulators
(IGRs) on the San JoaquinValleyCalifornia
integrated pest management program. Pyriproxyfen reduced the target pest, California red
scale, Aonidiella aurantii Maskell, to nondetectable levels on leaf
samples 4 mo after treatment. Pyriproxyfen treatments reduced the California red
scale parasitoid Aphytis melinus DeBach to a greater extent than the parasitoid Comperiella
bifasciata Howard collected on sticky cards. Treatments of lemons Citrus
limon (L.) Burm. f. infested with scale parasitized by A.
melinus showed only 33% direct mortality of the parasitoid, suggesting
the population reduction observed on sticky cards was due to low host density.
Three years of pyriproxyfen treatments did not maintain citricola scale, Coccus
pseudomagnoliarum (Kuwana), below the treatment threshold and cottony
cushion scale, Icerya purchasi Maskell, was slowly but incompletely
controlled. Buprofezin reduced California red
scale to very low but detectable levels 5 mo after treatment. Buprofezin
treatments resulted in similar levels of reduction of the two parasitoids A.
melinus and C. bifasciata collected on sticky cards. Treatments of lemons
infested with scale parasitized by A. melinus showed only 7% mortality
of the parasitoids, suggesting the population reduction observed on sticky
cards was due to low host density. Citricola scale was not present in this
orchard, and cottony cushion scale was slowly and incompletely controlled by
buprofezin. These field plots demonstrated that IGRs can act as organophosphate
insecticide replacements for California red
scale control; however, their narrower spectrum of activity and disruption of
coccinellid beetles can allow other scale species to attain primary pest

Stephen, P.R. 2005. Use of an inexpensive technique to compare systemic
insecticides applied through drip irrigation systems in citrus. African
Entomology 13(2): 353-358. Notes: Throughout the world, farmers are
increasingly adopting the use of drip irrigation. As the quality and automation
of these irrigation systems improves, the feasibility of using them to apply
plant protection products, growth regulators and nutrients also increases. An
inexpensive means of evaluating such systemic products in a randomized block
layout is described and its use demonstrated in evaluating drip applications of
imidacloprid, methamidophos, monocrotophos, acephate and dimethoate in a
'Marsh' grapefruit (Citrus paradisi Macf.) orchard in Swaziland.
Efficacy was tested against Toxoptera citricida (Kirkaldy), Scirtothrips
aurantii Faure and various species of mealybug (Pseudococcidae).
Imidacloprid and dimethoate proved the most promising systemic treatments, but
usage of dimethoate on citrus trees with fruit destined for export to the
European Union has now been restricted by the recent lowering of maximum
residue limits for dimethoate. The sequential application of imidacloprid (2.1
g [AI] per tree) via drip followed by a petal-fall spray of spinosad (0.0072%
[AI]) plus horticultural mineral oil (0.3%) was more effective against S.
aurantii, but less efficacious against mealybugs, than dimethoate (36 g
[AI] per tree) via drip followed by spinosad plus oil (dosages as above)
applied at the same times.

South African gall-inducing scale insect, Calycicoccus merwei Brain
(Hemiptera: Coccoidea: Eriococcidae). African Entomology 14(1): 13-33. Notes:
The scale insect genus Calycicoccus Brain has a single
described species, C. merwei Brain, which is endemic to southeastern South
Africa. Females of C. merwei induce small,
mostly conical galls on the foliage of their host tree, Apodytes dimidiata E.
Meyer ex Arn. (Icacinaceae), which has a wider, mostly coastal distribution,
than that currently known for the scale insect. Calycicoccus has been
placed in the family Eriococcidae and may be related to the South American
genus Aculeococcus Lepage. No other native eriococcid species have
been described so far in South
Africa, although the family is diverse in other
Gondwanan regions. This paper summarizes the biology of C. merwei, redescribes
the adult female, describes the adult male, the second-instar female and the
first-instar nymphs for the first time, and reconsiders the phylogenetic
relationships of the genus. The adult female is shown to have unusual abdominal
segmentation, in that segment I is present both dorsally and ventrally, but a
segment is absent ventrally on the middle abdomen. First-instar nymphs are
sexually dimorphic; males have a larger and relatively narrower body, larger
mouthparts, longer antennae and legs, and more thoracic dorsal setae compared
with females. Molecular data from nuclear small-subunit ribosomal DNA (18S) and
elongation factor 1 alpha (EF-1 alpha) show C. merwei to have no
close relatives among the Eriococcidae sampled to date. Instead, the Calycicoccus
lineage is part of a polytomy near the base of the Eriococcidae. Molecular
dating of the node suggests that the Calycicoccus lineage diverged from
other eriococcids more than 100 Mya. These data support the placement of Calycicoccus
as the only genus in the subfamily Calycicoccinae Brain.

scale, Cryptococcus fagisuga (Hemiptera: Eriococcidae), an invasive
pest in North America.
Biological Control: Theory and Applications in Pest
Management 39(1): 9-18. Notes: Beech scale, Cryptococcus fagisuga
Lindinger, is invasive in North America. The
immediate source of the introduction was Europe, but
its native range may be different. Knowledge of the native range is useful when
searching for coevolved natural enemies for classical biological control. We
report results of a search for the native range of C. fagisuga, using historical
records, field surveys, and molecular phylogenetics. Beech scale feeds
exclusively on beech. We review historical accounts of movement of species of Fagus
between Europe, Asia, and
North America and report on extensive surveys for C.
fagisuga on Fagus species in China and Japan. We
undertook a phylogeographic study of C. fagisuga throughout its known
range using sequences of the mitochondrial gene cytochrome oxidase I (COI). We
also investigated the phylogenetic relationships of C. fagisuga to other species
and related species in the Eriococcidae, using ribosomal DNA (18S). For COI
sequences within C. fagisuga, we found one widespread, most-common haplotype in
North America, Europe, Turkey, and Georgia; a diversity of slightly (0.1-0.5%)
divergent haplotypes in Bulgaria; a diversity of moderately (2.2-2.8%)
divergent haplotypes in Georgia and Turkey; and a highly (3.6-4.2%) divergent
group of haplotypes in Iran. Phylogenetic analysis of 18S places C.
fagisuga within a cosmopolitan clade of eriococcids feeding on other
temperate trees (ash, maple, and southern beech). Based on the phylogeographic
study, we suggest that the subspecies F. sylvatica orientalis is the
native host of C. fagisuga and that natural enemies are best sought on oriental
beech in northeastern Greece, the
Black Sea drainage basin, the Caucasus
Mountains, and northern Iran.

sugarcane. Journal (American Society of Sugar Cane Technologists) 25(143-156.
Notes: The number of insect and mite species attacking sugarcane in Florida
(USA) has increased in recent years. Five pest species were newly discovered
during the 31-year period, 1964-95. These included one species indigenous to Florida
having no previous association with sugarcane and four invasive species new to
the Everglades Agricultural Area where sugarcane is grown. Reported here are
six species that were discovered for the first time infesting Florida
sugarcane during the 8-year period, 1995-2003. They included: an armored scale,
divergens (Hemiptera: Diaspididae) and the pink sugarcane mealybug, Saccharicoccus
sacchari (Hemiptera: Pseudococcidae). Duplachionaspis divergens
grypus were found infesting sugarcane in greenhouses.

insects, and disease in apples and pears. Part III. Use of silicone-based
materials and mechanical methods to eliminate surface pests. Postharvest
Biology and Technology 40(3): 221-229. Notes: Surface arthropods on pome fruits
can cause export problems and disrupt commercial markets. Eliminating insects
and mites on the packing line would be the last opportunity to provide for
pest-free produce. In this study, an experimental packing line was used to
evaluate techniques using different surfactant baths, pressurized water sprays,
and styles of rotating brushes to remove field-collected and laboratory-reared
grape mealybug, Pseudococcus maritimus (Ehrhorn) (Homoptera: Pseudococcidae),
the diapausing two-spotted spider mite, Tetranychus urticae Koch (Acari:
Tetranychidae) and the woolly apple aphid, Eriosoma lanigerum (Hausman)
(Homoptera: Aphididae). The organosilicone Silwet L-77 was no more effective
than a silicone-based food grade defoamer in aiding removal. Mechanical
methods, such as the style of rotating brushes and pressurized sprays, were
significantly effective in removing surface arthropods. No improvement in
removal occurred when pressure was increased beyond 420kPa. These techniques
can be easily adapted to commercial facilities and will reduce the incidence of
surface arthropods on marketed fresh fruits.

Notes: Endophytic fungi, Neotyphodium spp., symbiotically
infect host grasses, Fescue arundinacea [Festuca arundinacea]
pratensis [Festuca pratensis], and mealybug Phenococcus solani [Phenacoccus
solani] attacks some forage plants. To evaluate the role of these fungi
to control this pest, four genotypes of F. arundinacea and two genotypes of F.
pratensis were used. Plant tillers were split into two sections, one
section of which was freed from the endophyte using a fungicide mixture. The
mixture contained 2 g of active ingredients of propiconazole and 1 ml of
Folicur [tebuconazole]/l of water. New tillers from endophyte-infected and
endophyte-free plants were transferred into the field. The number of mealybugs
was measured after the first visible sign of infestation on roots. To count
mealybugs, one plant hill of each plot was randomly selected. Hay yield of each
plot was measured by clipping the plants 5 cm above ground level. Correlation
of hay yield and other growth characteristics with the number of mealybugs on
roots as an index for mealybug damage on infested plants was determined. The
results indicated that the endophyte-free plants were highly infested with P.
solani compared with the endophyte-infected plants that were completely
free of P. solani. Correlation coefficients showed that there was a
significant negative correlation between forage yield and mealybug numbers,
indicating mealybug damage on infested plants. It seems that the endophytic
fungi are effective biological control factors for some root-feeding pest such

gomezii, is described from Costa
Rica, and another, S. meredithiae, is
described from Louisiana. S.
gomezii is most similar to S. septobasidioides, but macroscopic
and microscopic differences support it being a distinct species. S.
meredithiae is similar to S. alni and S. castaneum but differs
from these species in several macroscopic and microscopic characters,
especially when the species are observed on the same host tree and insect
species. Another species collected only once in Costa
Rica is listed with observations but it is not
formally described here. This Septobasidium species shares some
key characteristics with S. ramorum but combines a dense,
compact, nearly black thallus and pigmented probasidia-like structures with
spindle-shaped haustoria. Implications for taxonomy, morphological evolution
and host specificity in Septobasidium are discussed.

perola-da-terra, Eurhizococcus brasiliensis. (In Portuguese with summary in
English.) Agropecuaria Catarinense 18(2): 93-95. Notes: The root immersion of
grapevine seedlings in insecticide solution is a preplanting technique
recommended to control some eventual infestation of groundpearl, Eurhizococcus
brasiliensis. However, the minimum time in order to get 100% of insect
mortality as well as the eventual insect protection against insecticide in
clods must be determined. Clean and encrusted cysts of groundpearl were
immersed for 0, 1, 10, 60 and 120 seconds in a 0.08% a.i. methidathion
solution. Encrusted cysts in fungal coat were used to simulate the clod
protection against insecticide. Each experimental unit, replicated three times,
had 20 clean cysts or almost 10 encrusted cysts. The number of dead cysts was
recorded in 15- or 20-day intervals. The percentage of insect mortality was
proportional to the immersion time in insecticide solution and the time of 120
seconds resulted in 100% mortality, for both clean and encrusted cysts.

A technique for measuring growth rate and survival of armoured scale insects. New
Zealand Plant Protection 58: 288-293. Notes:
[Proceedings of a conference, Wellington, New
Zealand, 9-11 August 2005.] A method for
measuring the size and growth rate of armoured scale insects using digital
image analysis is described. It was used in a preliminary experiment that
demonstrated between-plant differences in the growth rate of armoured scale
insects on kiwifruit leaves. It also allowed the timing and extent of mortality
factors to be measured accurately. Heavy predation of armoured scale insects on
kiwifruit leaves, probably caused by earwigs, was observed for the first time.
The development of this technique as a tool for both ecological studies of
scale insect, and in measuring the relative resistance of kiwifruit germplasm
to armoured scale insects is discussed.

Morrison (Hemiptera: Coccoidea) and some related taxa based on the morphology
of adult males. Zootaxa 1263: 1-250. Notes: This paper outlines the history of
the family name Margarodidae (Hemiptera: Coccoidea) and of the higher classification
within Margarodidae sensu Morrison, and reviews the use of males in diagnosing the
higher taxonomy witin this group. An overview of the general morphology of
adult males is provided as an introduction to the terms and structures used in
the descriptive section that follows. The adult males of 31 species of
Coccoidea are described, covering all the families in Margarodidae sensu
Morrison plus some additional taxa which have either been included in
Margarodidae sensu lato in the past or which show close affinities to it.
Based on the structure of the adult males described here and also on an earlier
cladistic analyses, these 31 taxa are divided into three groups: Ortheziidae
(containing just ortheziids), a group here referred to as "margarodoid
taxa" (which includes all the taxa in Margarodidae sensu Morrison (1928)
except Steingelia; this group includes the following nine families:
Matsucoccidae, Margarodidae, Xylococcidae; Stigmacoccidae fam. nov.;
Kuwaniidae; Callipappidae; Marchalinidae; Monophlebidae and Coelostomidiidae);
and a third group referred to here as "non-margarodoid taxa", which
includes the remaining taxa considered in this paper (Steingelia, Stomacoccus,
Phenacoleachia, Puto and Pityococcus). The present higher
taxonomic status of each taxon is summarised in a Table and a key to identify
each family based on adult male morphology is included; this key also diagnoses
the above three groups based on adult male characters. Keys are also provided
under each family to identify the species described herein.

hellenica (Gennadius) (Hemiptera: Coccoidea: Marchalinidae) from Greece,
with a discussion on the identity of M. caucasica Hadzibeyli from the Caucasus.
Zootaxa 1196: 1-32. Notes: The morphology of the adult female, 1st-, 2nd- and
3rd-instar female nymphs, plus the pupa (4th-instar male) and apterous adult
male of M. hellenica (Gennadius), are described and illustrated, along
with the prepupa (3rd-instar male) of M. caucasica Hadzibeyli. A key is
provided to separate these stages. The adult female and 3rd-instar female of M.
caucasica were also seen and considered to be identical with the same
stages of M. hellenica. The morphology of the other stages of M.
caucasica (as described by Hadzibeyli) are compared with those of M.
hellenica described here and it is noted that there are some possibly
significant differences in the 2nd- instar and apterous adult males. In
addition, the known biology of these two species is also discussed and it is
concluded that, despite the similarities of the adult females, these
populations could still represent two separate species. A key is provided to
separate the adult females of margarodoids on pines in the eastern Mediterranean.

Effect of nitrogen fertility on reproduction and development of citrus
mealybug, Planococcus citri Risso (Homoptera: Pseudococcidae), feeding on
two colors of Coleus, Solenostemon scutellarioides L.
Codd. Environmental Entomology 35(2): 201-211. Notes: The effects of nitrogen
concentration on the reproduction and development of citrus mealybug, Planococcus
citri, were studied on two colors of coleus, Solenostemon scutellarioides.
Green and red-variegated coleus plants were supplied with varying applied
nitrogen concentrations (0, 25, 50, 100, 200, and 400 ppm) for 32 d before
being artificially inoculated with citrus mealybugs. Female citrus mealybug
life history parameters including eggs contained within the egg mass and
respective body cavity, body length (mm), and developmental time (d) were
measured. A modified micro-Kjeldahl digestion procedure followed by colormetric
assay was conducted twice throughout the study to assess leaf nitrogen
concentration. The results of this study show that the citrus mealybug life
history parameters were influenced by the applied nitrogen concentrations
(ppm), leaf nitrogen concentration (%), and total moisture content (g). Citrus
mealybugs feeding on both green and red-variegated coleus, receiving the high
nitrogen fertilizer concentrations (200 and 400 ppm) had the greatest egg
loads, were larger in size, and had the shortest developmental times. Leaf
nitrogen concentration also affected the citrus mealybug life history
parameters with those mealybugs feeding on plants containing the highest leaf
nitrogen contents having the greatest egg loads, larger in size, and the
shortest developmental times. In addition, total plant moisture content
impacted the citrus mealybug life history parameters similar to leaf nitrogen
concentration. However, this was based on plant architecture whereas percent
plant moisture content for both green- and red-variegated coleus was
comparatively similar for all nitrogen concentrations. The life history
parameters measured were more pronounced on green coleus compared with
red-variegated coleus, perhaps because of nitrogen allocation differences
between the two coleus colors. Thus, higher nitrogen concentrations, in the
form of supplemental fertilizers used in greenhouse production systems, leads
to an increase in the performance of citrus mealybugs as defined by increased
egg loads, larger mature females, and shorter developmental times on coleus
plants. These results indicate that the implementation of proper fertilizer
practices may lessen the likelihood of dealing with extensive insect outbreaks,
thus potentially reducing insecticide use.
Hollingsworth, R.G. 2005. Limonene, a citrus extract, for
control of mealybugs and scale insects. Journal of Economic Entomology 98(3):
772-779. Notes: In a series of bioassays with mealybugs, aqueous solutions of
1% limonene were tested that used from 0.50 to 1.50% all purpose spray adjuvant
(APSA)-80 as an emulsifier/surfactant. The two ingredients were added to water
or to 0.1% Silwet L-77, an agricultural surfactant. Using 1% limonene, 0.75%
all purpose spray adjuvant (APSA)-80 and 0.1% Silwet L-77, a semitransparent
mixture (primarily a microemulsion) was obtained that was safe for most plants
and provided good control of mealybugs when sprayed or used in 1-min dips. Used
at half strength, this mixture controlled approx. 99% of whiteflies, whereas
the full-strength mixture controlled from 69 to 100% of mealybugs and scales,
including approx. 93% control of root mealybugs. In side-by-side greenhouse
tests, this mixture was superior to a 2% solution of insecticidal soap or a 2%
solution of horticultural spray oil. Mortality of green scales on potted
gardenia plants averaged 95, 89, and 88% on plants sprayed with liminene,
insecticidal soap, or horticultural oil, respectively. In a related test, these
same sprays killed 44.1, 22.7, or 12.5% of third and fourth instar clustering
mealybugs, respectively. Limonene has promise as a safe, natural pesticide for
insect pests on tolerant plants. Although 1% limonene solutions damaged certain
species of ferns, gingers and delicate flowers, they caused no damage to
ornamentals with thick, waxy leaves, such as palms, cycads and orchids. Among
the species tested were Chrysomphalus aonidum, Coccus viridis,
Nipaecoccus nipae, Planococcus citri, Pseudococcus longispinus, and Rhizoecus

Results showed that spraying with 40% methidathion EC (1:1000) + 40%
chlorpyrifos EC (1:1000) + 40% omethoate EC (1:500) was the most effective
treatment. Moreover, compared with using 40% methidathion EC, 40% chlorpyrifos

[The occurrence regulation of Pseudococcus comstocki in apple
orchard.]. (In Chinese.) China
Fruits 4: 32-34. Notes: Observations were conducted in an apple orchard with
15-year-old trees of Red Fuji cultivar, where all the fruit on the trees was
bagged. The annual production usually was around 45 t/ha. In this orchard over
50% of the bagged fruit were usually infected with Pseudococcus comstocki.
Observations revealed that its eggs were laid in trunk bark gaps (62% located
near the root collar). The hibernated eggs incubated in late March till late
April, then the nymphs attacked the tender tissue of the tree. The nymphs of
the second generation started to enter the bags and attack the fruit. On rainy
days, damage was exacerbated. Pseudococcus comstocki usually
attacks the calyx part of the fruit and induces the formation of black spot,
thus the fruit quality is severely damaged.

Life history and natural enemy associations of calico scale (Homoptera:
Coccidae) in Kentucky.
Journal of Economic Entomology 98(4): 1202-1212. Notes: Seasonal phenology of
calico scale, Eulecanium cerasorum (Cockerell), was monitored for 3 yr on
various deciduous tree species in central Kentucky.
Infestations were found on 16 host species in six plant families. Calico scale
is a univoltine parthenogenic species that overwinters as second instars on
bark. Nymphs molted to adult females around mid-April and began producing eggs
in late April. Mean fecundity ranged from 3,728 to 4,654 eggs per female,
depending on host plant species. Date of first crawler hatch in 2001-2003
ranged from 21 to 26 May, corresponding to a mean accumulation of 818 +- 2
Celsius degree-days (DDC), calculated from 1 January and a base of 4.4 Degree
C. This value predicted, crawler hatch within 2 d in Lexington, KY, in
2004. Crawler dispersal lasted 2 to 3 wk. Upon hatching, crawlers move to
leaves where they feed during summer. Crawlers primarily settled on the abaxial
side of leaves and their within-leaf distribution varied between different tree
species. Settled crawlers molted in mid-July and second instars remained on
leaves until late September through mid-October, when they returned to bark to
overwinter. On hackberry, Celtis occidentalis L., they were
concentrated toward the basal end of shoots, primarily because leaf flush
continued beyond the end of the crawler dispersal period. Crawler distribution
did not differ between upper and lower canopy zones. Fourteen species of
parasitoids and a coccinellid beetle were reared from individual scales.
Monitoring with sticky traps in tree canopies confirmed that targeting crawlers
with insecticides during late May or June would not coincide with peak flight
activity of the scale's primary parasitoids.

Managing calico scale (Hemiptera: Coccidae) infestations on landscape trees.
Arboriculture & Urban Forestry 32(4): 138-147. Notes: Calico scale, Eulecanium
cerasorum (Cockerell), an invasive pest of shade trees, has reached
outbreak levels in landscapes and on horse farms in Kentucky, U.S. We
evaluated efficacy and timing of conventional and reduced-risk foliar
insecticides as well as trunk-injected or soil-applied systemics for managing E.
cerasorum. Acephate, bifenthrin, carbaryl, cyfluthrin, and pyriproxyfen
killed young settled crawlers on individually sprayed shoots. Whole-canopy
pyrethroid sprays, however, gave < 66% control, underscoring the difficulty
of reaching settled crawlers within large shade trees. Horticultural oil and
insecticidal soap were relatively ineffective even with full spray coverage.
Preventive sprays with bifenthrin or pyriproxyfen in mid-May, at first egg
hatch, intercepted crawlers before they settled on leaves. Dormant oil failed
to control overwintered nymphs or reduce subsequent numbers of adults or crawlers.
A plant antitranspirant applied in late March provided 33% suppression.
Trunk-injected imidacloprid was ineffective, whereas dicrotophos (bidrin) gave
at best < 50% control. Soil injection with imidacloprid in November,
December, or March failed to reduce subsequent densities of adults on branches
or crawlers on leaves. Reasons why it is difficult to eliminate calico scale in
mature landscape trees are discussed in the context of the pest's feeding sites

History and future of introduction of exotic arthropod biological control
agents in Spain: a
dilemma?. BioControl 5(1): 1-30. Notes: The first documented introduction of an
exotic invertebrate biological control agent (IBCA) in Spain
occurred in 1908. Sixty-four additional species have been introduced since
then. Information, both previously recorded and original data, on the species
introduced for pest control is summarized. Most of the introduced IBCAs focused
on citrus pests and homopterans (including Diaspididae) clearly predominate
among target phytophagous species. Success has been more frequent for IBCAs
used in seasonal inoculative strategies (50.0% of cases) than in classical
biological control programs (17.1% of cases). Concerns about potential
non-target effects of such species are increasing, but post-release evaluation
has often been insufficient to draw any conclusions about them. Most of the
beneficial species introduced in Spain were
parasitoids (n = 53), and the remaining species were predators (n = 12). Only
four parasitoids are considered specialized monophagous natural enemies. The
mean number of host species parasitized by parasitoids is 15.2, whereas the
mean number of prey species attacked by predators is 21.2. Therefore, polyphagy
appears to be quite common among the IBCAs that have been introduced in Spain. The
rationale guiding many of these introductions in the past would not be
acceptable nowadays. Since classical biological control is such a valuable
strategy for pest control, straightforward protocols to evaluate exotic
candidate species are urgently needed.

invasibility of maritime pine stands by the bast scale, Matsucoccus feytaudi
(Homoptera: Margarodidae). (In English with summary in French.) Canadian
Journal of Forest
Research 36(2): 314-323. Notes: Species-rich plant communities may be more
resistant to invasive herbivores because of reduced host-plant accessibility
and increased natural enemy diversity and abundance. We tested these hypotheses
in Corsica, a Mediterranean island recently invaded
by the maritime pine bast scale, Matsucoccus feytaudi Duc., which
causes widespread tree mortality in Pinus pinaster Ait. The endemic Matsucoccus
pini Green infests Corsican pine, Pinus nigra laricio Poiret, where it
is controlled by the native predatory bug, Elatophilus nigricornis Zetterstedt.
As revealed by kairomone trapping, E. nigricornis was most abundant in
pure Corsican pine in areas not yet colonized by M. feytaudi, and in pure
maritime pine its density decreased with the distance from the nearest Corsican
pine forest. The abundance of M. feytaudi was compared in five
pairs of Pure maritime pine and mixed maritime and Corsican pine stands. It was
consistently higher in pure than in mixed maritime pine stands, whereas E.
nigricornis showed the opposite pattern, and relative differences were
correlated with the proportion of Corsican pine in the Mixture. The predation
nigricornis was manipulated in pure maritime pine stands using
synthetic attractants of the predator. Matsucoccus feytaudi density was
significantly reduced in maritime pines baited with kairomone dispensers.

Evaluation of ethofenprox toxicity to male lac insect and its effect on
broodlac yield. Shashpa 12(2): 114-116. Notes: A field experiment was conducted
in Ranchi, Bihar, India, to
evaluate the detrimental effect of ethofenprox [etofenprox] based on the time
of application. The treatments comprised: 0.05; 004; 0.03; 0.02; 0.01; and
0.005% ethofenprox, applied on Schleichera oleosa trees inoculated
lacca. Ethofenprox was found to be a suitable insecticide for
application in lac ecosystem as it manages all 3 major lac insect predators,
amabilis and Pseudohypatopa pulverea, if applied
at proper times. However, the application of this insecticide a day prior to
the probable time of emergence of male lac insect causes toxicity, resulting in
loss of brood value of the produce as most of the female insects remain
unfertilized, thereby affecting the quality of the produce. There is a
quantitative loss in the resin secreted by the unfertilized females which is
approximately one-third of that secreted by fertilized female insects. The
results suggest that ethofenprox should not be applied in lac culture either at
the time of male emergence or near to that time.

Lessons of the changes in the arthropod population composition in the Hungarian
apple orchard in the last six decades. Acta Phytopathologica Academiae
Scientiarum Hungaricae 41(1/2): 165-176. Notes: About 2500 arthropod species
immigrate, or carried by wind, or introduced by man in the orchards, under
Hungarian climatic conditions. However, the number of the apple pest species is
approximately 30. Owing to the effect of the relationships among the
plant-phytophagous-zoophagous species those could colonize the orchard for
which the apple provides suitable food sources and whose populations are not
regulated or are regulated by a weak efficiency by parasitoids and predators.
These populations create the primary pest communities. When the individual
number of the parasitoid and predator species is reduced by the broad-spectrum
insecticides, the population density of those phytophagous species could increase
whose populations was restricted up to that time. In this case the secondary
pest communities could develop. The integrated pest management provides the
possibilities to solve the problems caused by the regular use of broad-spectrum
insecticides. The real requirement is to find and to harmonize those methods
which regulate the population dynamics of the species of the primary pest

Naturally occurring quinones and flavonoid dyes for wool: Insect feeding
deterrents. Journal of Applied Polymer Science 98(1): 322-328. Notes: This
study investigated the ability of natural dyes to impede the attack of black
carpet beetles on wool. The dyes evaluated were naturally occurring quinines
(cochineal, madder, and walnut) and flavonoids (chestnut, fustic, indigo, and
logwood). All of the dyes, except indigo, were applied by using five mordanting
agents (aluminum, chrome, copper, iron, and tin). Mordanting agents were used
to bind natural dyes on wool. The insect resistance of the controls and dyed
specimens was evaluated, following the fabric weight loss procedures in AATCC
Test Method 24. All of the dyes, except indigo, increased the insect resistance
of the wool fabric to attack by black carpet beetles. The wool specimens dyed
with cochineal and madder, naturally occurring anthraquinone dyes, had the
lowest fabric weight loss among eight natural dyes investigated. The flavonoid
dyes were not effective in enhancing insect resistance. Alum, copper, and iron
have no significant effect on enhancing or reducing insect resistance of any of
the eight natural dyes used in this study. However, tin and chrome, when used
as a mordant for cochineal, reduced the insect resistance dramatically.
Surprisingly, tin improves the insect resistance of wool fabrics dyed with
fustic dyes. The anthraquionones, including cochineal, madder, and walnut were
found to be quite effective in protecting wool fabric against black carpet
beetles. Thus, the naturally occurring mordant dyes provide an alternative to
insecticides in protecting wool textiles from insect attack.

caterpillar and undamaged shoots. Reed shoots that were damaged by the
stem-borer in spring change morphologically during summer, inducing tillers
from the nodes beneath the damaged part. The number of female scales per shoot
did not differ significantly between damaged and undamaged shoots in the second
scale generation (September), but was significantly lower on damaged shoots in
the third generation (November). Three parasitoid species attacking the scale
exhibited different responses to the shoot damage, with the response by each
parasitoid being constant in the two scale generations: the parasitism rate by Aprostocetus
sp. per shoot was higher on damaged shoots, whereas that by Astymachus
japonicus was lower on damaged shoots, and no difference was detected
depressa. In the third scale generation the parasitism rate by
Encyrtidae sp. 1 showed no difference, with respect to shoot damage, whereas
that by Encyrtidae sp. 2 was lower on damaged shoots. In three dominant
parasitoids, shoot damage had no effect on the number of emerging adults per
host, and the sex ratio and body size of the adults. The number of emerging
adults per shoot differed significantly between damaged and undamaged shoots
for four parasitoids, except B. depressa. These results suggest
that shoot damage by the stem-borer exerts a delayed negative impact on the
scale numbers and affects the parasitism rate of the scales by three
parasitoids and the emerging adult numbers of four parasitoids.
Kaneko, S. 2005a. Seasonal population changes of five
parasitoids attacking the scale insect Nipponaclerda biwakoensis on the
common reed, with special reference to predation by wintering birds.
Entomological Science 8(4): 323-329. Notes: Seasonal changes in the abundance
of five species of hymenopterous parasitoids (four species of Encyrtidae and
one species of Eulophidae) attacking the scale insect Nipponaclerda biwakoensis
on the common reed were investigated for 2 years in LakeBiwa,
with special reference to predation by the reed bunting, Emberiza schoeniclus,
during winter. The scales settled on reed shoot stems under sheath leaves,
passing through three discrete generations per year. The abundance of adult
female scales increased exponentially from July (first generation) to December
(third generation). Adult female scales of the third generation overwintered on
reed shoots. During winter, female scale abundance dramatically declined,
whereas the number of predation marks made by reed buntings using their bills
on reed sheath leaves increased. The generations of all five parasitoids were
synchronized with the host scale generations, and the five parasitoids
overwintered as larvae inside the scale bodies. The abundance of parasitized
scales and parasitoid adults emerging from the scales also increased from July
to December, but greatly decreased during winter. The overall parasitism rate
of the female scales remained at relatively low levels (less than 40%)
throughout the year, including before and after winter. A bird exclusion
experiment revealed that the dramatic winter decrease of the abundance of the
scale and its five parasitoids was due to intensive and non-selective predation
by the buntings on unparasitized and parasitized scales. Additionally, the
proportion of immature parasitoids removed by birds varied between the five parasitoid
species. Thus, seasonal population changes of the five scale parasitoids are
considerably affected by bird predation on overwintering immature parasitoids.

Investigation of red natural dyes used in historical objects by HPLC-DAD-MS.
Annali di Chimica 96(1-2): 75-84. Notes: High performance liquid chromatography
(HPLC) with UV-Vis Diode Array Detection (DAD) and electrospray mass
spectrometric (ESI-MS) method was utilized for the identification of coloring
components of madder, Armenian and Mexican cochineal, lac dye, brazilwood,
safflower and dragon blood - probably the most important red natural dyestuffs
found in objects of the Cultural heritage. UV-Vis detection limits in the range
of 0.2-0.6 ng for carminic acid, alizarin and purpurin were achieved using a
gradient elution of H2O-0-01%TFA and CH3CN-0.01%TFA. ESI mass spectrometer was
also used, as a supportive detection method to the standard DAD, for further
analysis of the tested materials, with the ability to analyze dyestuffs as
small as one milligram. The presence of madder was revealed in two historical
(Hellenistic and Roman period) samples, found in the Mediterranean area, by
identifying purpurin in both of them. Munjistin was also identified in one of
thesamples (Hellenistic period)
while alizarin was not detected, raising questions regarding the exact madder
type, utilized in the historical samples.

Genomic imprinting in the mealybugs. Cytogenetic and Genome Genetics 113(1/4):
41-52. Notes: The coccid insects (Hemiptera; Sternorrhyncha; Aphidiformes;
Coccoidea; Pseudococcidae) are well suited to study not only the mechanisms of
genomic imprinting but also facultative heterochromatization, a phenomenon well
exemplified by inactivation of the X chromosome in female mammals. Coccids show
sex-specific heterochromatization of an entire set of chromosomes and
transcriptional silencing of all the paternally contributed chromosomes in
males. Thus, genomic imprinting and the resultant differential regulation
operate on 50% of the genome in contrast to the single X chromosome in female
mammals. A significant insight into the phenomenon of genomic imprinting has
come from very elegant cytological analysis of the coccid system. Recently,
efforts have been made to dissect out at the molecular level the phenomenon of
genomic imprinting in these insects. The present review summarizes both of
these aspects. In light of the accruing experimental evidence for chromatin-based
differences in the maternal and paternal genomes, it appears that the mealybug
system may provide evidence for stable maintenance of chromatin code not only
through mitosis but also through meiosis.

females and migration of crawlers of Pseudaulacaspis prunicola
(Homoptera: Diaspididae) on cherry trees in JejuIsland. (In
Korean with summary in English.) Korean Journal of Applied Entomology 44(3):
231-235. Notes: This study was conducted to obtain the optimal spray time for Pseudaulacaspis
prunicola (Maskell) (Homoptera: Diaspididae) in early season in Jeju.
Oviposition time of overwintered females and activity of hatched nymphs of P.
prunicola were monitored, and the Oenology data were compared with the
outputs estimated by a degree-days model of P. pentagona
(Targioni-Tozzetti)). Overwintered females of P. prunicola began to lay
eggs from mid to late April, and the eggs started to hatch from early May
followed by the active migration of the hatched nymphs during mid May. The
Oenological events of P. prunicola in early season were
likely comparable with those of P. pentagona reported in southern Korea and
in central Japan. A
degree-day model, which predicts the proportion of >50% hatched egg batches
pentagona (y=1/ (exp(-(-a+bx))); y, proportion; x, degree-days based on
10.5[degree]C from 1 January; a=-18.80 and b=0.073), accurately described the
migration time of P. prunicola hatched nymphs. Thus, it is considered that the
degree-day model can be used for predicting the optimal spray time for P.
prunicola in early season.

Biological characterization of the obligate symbiosis between Acropyga
sauteri Forel (Hymenoptera: Formicidae) and Eumyrmococcus smithii
Silvestri (Hemiptera: Pseudococcidae: Rhizoecinae) on OkinawaIsland,
Journal of Natural History 39(40): 3501-3524. Notes: The ant Acropyga
sauteri Forel has an obligate, mutualistic symbiosis with a mealybug, Eumyrmococcus
smithii Silvestri, on OkinawaIsland,
southern Japan. The
mealybugs live inside ant nests nearly all their lives, and the ants depend on
them for food. Alate foundress queens carry mealybugs during their nuptial
flights, using them to establish new colonies at new sites. However, important
aspects of the symbiosis have not yet been elucidated. The present study
characterizes the basic biology of the symbiosis and describes for the first
time the morphologies of all growth stages of E. smithii. Our study suggests
that E. smithii has only one nymphal stage, followed by a female pupal stage or
male prepupal stage. Intensive sampling of ant nests across seasons showed that
sauteri prefers nest sites 5-20 cm underground. Acropyga sauteri produced
reproductive stages mainly in mid-March or early April, and numbers of both ant
workers and mealybugs increased from spring to summer. Experimental
determination of colony identity with a method using nestmate recognition by
ants suggested that each ant colony rarely has a perimeter greater than 30 cm,
that the ants are monogynous, and that different ant colonies are densely
aggregated along the root system of a plant, adjacent to each other but not
interflowing. Both symbiotic partners were vulnerable to attacks by several
common subaerial ant species following physical disturbance to their nests.

Annual Conference, Thailand, 1-4
February, 2005. Subject: Plants. Bangkok: KasetsartUniversity.Notes: Anagyrus dactylopii (Hymenoptera:
Encyrtidae) is an important parasite of the spherical mealybug Nipaecoccus
viridis (Homoptera: Pseudococcidae) infesting citrus. A study on the
biology of A. dactylopii revealed that the incubation period was
1.20+/-0.42 days. The larval stage consists of three instars. A pre-pupal stage
was also present. The mean durations of the three instar larvae, pre-pupa,
pupa, adult male and adult female were 1.65+/-0.49, 1.85+/-0.37, 2.20+/-0.41,
1.85+/-0.37, 4.75+/-0.44, 14.12+/-3.87 and 22.72+/-5.10 days, respectively.
Development from egg to adults was approximately 9-16 days. An investigation on
the efficiency of A. dactylopii for the parasitization of various stages of N.
viridis revealed that the percent parasitization increased when the
nymph stage of the mealybug augmented. Further study on the population of the
parasite and its host in the field revealed the occurrence of the population of
dactylopii depending on the population of the spherical mealybug. The
highest parasitization was 54.30% in April 2003 and the mean parasitization all
over the year at Amphoe U-Thong, Thailand was

Description of two new genera and species of Eriococcidae (Hemiptera:

Eriococcidae, Intecticoccus Kondo and Orafortis Hardy, each with a new
viridis Kondo and O. luna Hardy), are described and
illustrated based on the adult females. I.
viridis was collected on Nothofagus antarctica
(Nothofagaceae) in Argentina and Chile, and
luna was collected in Chile on Amomyrtus
luna (Myrtaceae). Based on a phylogenetic analysis of SSU rDNA (18S)
sequence data, I. viridis and O. luna are placed within the
Gondwanan group of eriococcids (Sensu Cook & Gullan 2004), which
also includes other Nothofagus-feeding genera such as Chilechiton Hodgson &
Miller, Chilecoccus Miller & Gonzalez and Madarococcus Hoy. Major
genera within the Gondwanan goup that feed on other plant groups include Lachnodius
Maskell, Opisthoscelis Schrader and some species currently assigned to Eriococcus
Targioni Tozzetti. We consider that I.
viridis and O. luna are each sufficiently distinct from other named taxa to
warrant erection of two new genera. DNA data do not support a relationship of Chilechiton
with the New Zealand
genus Eriochiton Maskell. A revised taxonomic key to the adult female

(Coccinea) associated with mites (Acari) in the fossil record. Polskie Pismo

Coccinea) were associated with mites (Acari) in some 1900 examined inclusions
from Lebanese amber (Lower Cretaceous), New Jersey and Taymyrian amber (Tipper
Cretaceous), Baltic and Bitterfeld amber (Tertiary, Eocene). The parasitized
scale insects belonged to 6 families: Ortheziidae, ?Steingeliidae,
Electrococcidae, Kuwaniidae, Pityococcidae and Inkaidae; all but the latter are
archeococcids. The frequency of this association was particularly high in
species of Pityococcidae; within 64 examined specimens, 8 were associated with
mites. The parasites were associated with crawlers, larvae, adult females and
males. From one to five mites were attached to a single coccid. In some cases,
it was difficult to determine if the association represented phoresy or
parasitism however in many associations the mouthparts of the mites were still
attached to the host. It is suggested that mites played a major role in
controlling scale insect populations during the Cretaceous.

New Guinea. Journal of Applied Entomology 129(6):
323-329. Notes: In order to evaluate the possibility of classical biological
control of the pink wax scale Ceroplastes rubens (Hom., Coccidae)
with the parasitoid Anicetus beneficus (Hym., Encyrtidae), endemic parasitoids were
collected (2000/2001) in three provinces in Papua New Guinea and parasitization
levels were determined. Eight hymenopteran parasitoid species were identified: Aprostocetus
sp. (Eulophidae), Coccophagus sp. (Aphelenidae), five Encyrtidae: Cheiloneurus
sp. and Moranila sp. (Pteromalidae). Levels of parasitization were low,
varying between 1.4 and 2.8%. A. beneficus was imported from Australia and
1100 specimens were released in spring 2002 at two locations with mango
infested by C. rubens (Laloki and Tahira) in the CentralProvince. A.
beneficus did establish at both sites. Six months after release,
parasitization levels of C. rubens had increased from 2.8 to
5.9% (P=0.05) at Laloki and from 1.8 to 22.2% (P=0.01) at Tahira, with A.
beneficus being the most frequent parasitoid (69% of all parasitoids).
Workers of the ant genus Tapinoma (Dolichoderinae) were
frequently collected from infested trees at Laloki, but were not present at
Tahira. It is assumed that their presence is at least partly responsible for
the lower degree of parasitization and number of A. beneficus at this
site. The necessity of further studies is stressed.

Stem application of neonicotinoids to suppress Coccus viridis (Green)
population in coffee plantations. Annals of Plant Protection Sciences 14(1):
73-75. Notes: Two field trials were carried out during August 2002 and March
2003 at 2 locations in Yercaud, Tamil Nadu, India, to assess the efficacy of
application of neonicotinoids on the auxillary branches (first experiment) and
main stem (second experiment) of coffee (Coffea arabica) plants against Coccus
viridis. The treatments comprised thiamethoxam 25 WG at 0.025 and 0.050
g/plant, imidacloprid 17.8 SL at 0.025 g/plant, imidacloprid 80 SL at 0.050
g/plant, dimethoate 30 EC at 0.300 g/plant, and an untreated control. In both
trials, imidacloprid and dimethoate were included as the standard controls. The
application of thiamethoxam at 0.05 g/plant on the auxillary branches was very
effective in suppressing the population of Coccus viridis, causing 93.1%
reduction. The application of insecticides on the main stem was less effective.
Thiamethoxam at 0.025 g/plant was comparable with imidacloprid (0.050 g/plant)
and dimethoate (0.300 g/plant).

synthetic and natural food dyes on activities of CYP2A6, UGT1A6, and UGT2B7.
Journal of Toxicology and Environmental Health. Part A. 68(16): 1431-1444.
Notes: Synthetic or natural food dyes are typical xenobiotics, as are drugs and
pollutants. After ingestion, part of these dyes may be absorbed and metabolized
by phase I and II drug-metabolizing enzymes and excreted by transporters of
phase III enzymes. However, there is little information regarding the
metabolism of these dyes. It was investigated whether these dyes are substrates
for CYP2A6 and UDP-glucuronosyltransferase (UGT). The in vitro inhibition of
drug-metabolizing enzymes by these dyes was also examined. The synthetic food
dyes studied were amaranth (food red no. 2), erythrosine B (food red no. 3),
allura red (food red no. 40), new coccine (food red no. 102), acid red (food
red no. 106), tartrazine (food Yellow no. 4), sunset yellow FCF (food yellow

as an insecticide or as an adjuvant in pesticide preparations. This article examines
the properties of paraffin oil (and mineral oils in general) in terms of
density, adhesion and mechanism of activity. Results are presented of tests
carried out since 1998 at Skierniewice, Poland, on
the effectiveness of paraffin oil-based insecticidal products for the control
of pests on ornamental shrubs and trees, including conifers, under garden and
commercial conditions. The products tested included Floril 019 AL, Promanal 012
AL, Promanal 60 EC, Treol 770 EC and Paroil 95 EC. This last was particularly
effective against Panonychus ulmi, Oligonychus ununguis, Schizotetranychus schizopus,

myrmecophytes: Patterns of abundance and implications for mutualism function
(Hymenoptera: Formicidae). Sociobiology 46(2): 433-442. Notes: We assessed how
the abundance of ant-tended Hemiptera associated with two Amazonian
myrmecophytes, Tococa bullifera and Maieta guianensis, varied as a
function of resident ant species. We collected five species or morpho-species
of adult Hemiptera in the domatia of M. guianensis, with four of these
species also found in Tococa bullifera. Maieta guianensis plants inhabited
laevis had over four-fold more Hemiptera in them than plants inhabited
minutula. In contrast, the density of Hemiptera in Tococa bullifera domatia
was independent of the species of ant resident. For each of the two ant species
inhabiting Maieta guianensis, there was a positive and significant
relationship between the abundance of Hemiptera and workers inhabiting a plant.
This relationship was also significant and positive for the Tococa
bullifera plants inhabited by C. laevis. However, there was no
relationship between Azteca worker and hemipteran density, although there was a
trend towards a positive relationship. Our results indicate that hemipteran
abundance can vary significantly between different myrmecophyte species, but
that the nature of this relationship is mediated by the identity of the ant
associate. Because hemipterans are herbivores, the costs and benefits of
different ant partners to the host plant may vary in ways that are often
overlooked. Coccus hesperidum, C. viridis, Dysmicoccus sp. and Nipaecoccus
sp. are the species discussed.

Phylogenetic position of the ant genus Acropyga Roger (Hymenoptera:
Formicidae) and the evolution of trophophoresy. Insect Systematics &
Evolution 37(2): 197-212. Notes: Trophophoresy is exhibited in two ant genera: Acropyga
(Formicinae), in which all 37 species are thought to be trophophoretic, and
Tetraponera (Pseudomyrmecinae), in which it has been observed in only one
species, T. binghami. This study analyses a dataset comprised of both
morphological and molecular (D2 region of 28S rRNA and EF1-alpha) data.
Evidence is presented in favor of Acropyga being monophyletic, hence
trophophoresy has evolved only once within the Formicinae and twice within the
ants overall. The data further suggests that Acropyga belongs within a
clade containing Anoplolepis, Aphomomyrmex, and Petalomyrmex.
were found to be the sister group to Acropyga. The results indicate that
the Lasimi and Plagiolepidini are not monophyletic and are in need of
reexamination. Given the extant pantropical distribution of Acropyga
it is speculated that Acropyga maybe of Gondwanan origin
and that trophobiosis was the first form of agriculture to evolve in the ants.

Liang, A.P. 2005. [A proposal to stop using the insect
order name "Homoptera".]. (In Chinese with summary in English.)
Chinese Bulletin of Entomology 42(3): 332-337. Notes: The advent of cladistics
and its wide use has greatly improved our knowledge of many higher taxa in
biota and many artificial (non-monophyletic) taxa. The insect order Homoptera
is one of those non-monophyletic groups recognized in recent years. More and
more morphological and molecular evidence has indicated that the traditional
Homoptera is not a natural group but is a paraphyletic relative of Hemiptera.
However, many Chinese entomologists are not aware of this development and the
order name Homoptera, together with its concept is still widely used in many
Chinese entomological literatures such as textbooks, faunal work, taxonomic
monographs, dissertations and various scientific papers. The present author,
then, makes this appeal to the Chinese entomologists, proposing to stop the use
of the insect order name Homoptera and to use the monophyletic ordinal name
Hemiptera to include the true bugs and what were previously known as the
homopterans, including the psyllids (Psylloidea), whiteflies (Aleyrodoidea),
aphids (Aphidoidea), scale insects (Coccoidea), cicadas (Cicadoidea),
spittlebugs or froghoppers (Cercopoidea), leafhoppers (Membracoidea), treehoppers
(Membracoidea) and planthoppers (Fulgoroidea).

japonicus occurrence in jujube orchards.]. (In Chinese with summary in
English.) Yingyong Shengtai Xuebao 17(3): 472-476. Notes: Employing community
character indices and canonical correlation analysis, this paper studied the
insect community structure and its relationship with the occurrence degree of Ceroplastes
japonicus in jujube orchards. The results showed that based on the
community discrepancy coefficient of 0.20, the insect community in various
sampling fields could be categorized into two groups, i.e., plain and hill. The
occurrence of C. japonicus in the plains was more numerous, with lower insect
community diversity, smaller species number, and a higher dominance of
phytophagous insects, while that in the hills was less numerous, with more
likely insect community diversity, more abundant species, and a higher dominance
of natural enemy insects. Canonical correlation analysis indicated that at the
significant level of 0.05, the first and second pairs of canonical correlation
coefficients of C. japonicus occurrence characters and insect community
characters were 0.9904 and 0.8538, respectively, suggesting that the occurrence
japonicus was significantly correlated with the characters of insect
community. Community diversity (with the coefficient of 3.4893), species number
(with the coefficient of 5.8060), and dominance (with the coefficient of
6.9353) have the most important effects on the occurrence of C.

important citrus pests. To determine coccoideos population levels and to count
parasitized hosts decennial samplings were made. The rate of parasitism was
also calculated, as well as the distribution and dynamics in each population.
Populations were characterized for presenting greater increases from September
to February. Pn-P. ziziphi; Pb-P. ziziphi, Pb-L. gloverii and Pb-L.
beckii showed similarities among them, but they were significatively
different from Pn-L. beckii and Pn-L. gloverii. Orange population
infested 47.7% of P. ziziphi, 0.35% of L. beckii and 0.9% of L.
gloverii, whereas the white population over-parasited 61, 0.85 and 1.4%
of the same species respectively. The species of coccoidias showed greater
hyperparasitism of P. ziziphi, with significant differences compared to L.
beckii and L. gloverii.

Proceedings of the meeting of the International Organization for Biological and

scale Aonidiella aurantii (Maskell) is an important pest of citrus
orchards in Spain. It
causes cosmetic damage to the fruit resulting in downgrading in the
packinghouses. Several populations of A. aurantii in citrus orchards from Valencia were
tested for resistance to the insecticide chlorpyrifos during 2003-2004. All
tests were made by bioassays. Fruits infested with first immature stages were
dipped for 10 seconds in different concentrations of the chemical between 50
and 20,000 ppm of active ingredient. Mortalities were assessed after 15 days,
considering dead those insects that had not developed to the second stage. The
estimated CL SUB 50 was used in order to compare the values of susceptibility.
The results showed important differences between orchards. Susceptibility was
usually correlated with the history of previous treatments made in the plot,
with greater degree of resistance in orchards with more previous applications.
Some plots showed a high degree of chlorpyrifos resistance, with CL SUB 50
values 250 times higher than those found in the most susceptible plots.

crawlers (Hemiptera: Diaspididae) that settled on fruit of commercial kiwifruit
cultivars Actinidia arguta cv. K2D4, A. chinensis cv. Hort16A and A.

increased as the fruit matured. The settlement of greedy scale was greater than
on Hort16A fruit, with minimal differences between scale species on other
cultivars. Comparisons of scale settlement with scale phenology found fruit of
K2D4 was vulnerable to settlement from the first summer generation, with
second-generation scale mainly infesting Hayward
fruit. Hort16A fruit can be infested by both generations. Implications of these
findings for the pest status of scale insects, and customisation of the

diversity of insects in saltcedar woodlands in Xinjiang, West
China. (In Chinese with summary in English.) Shengtaixue Zazhi 25(2):
189-193. Notes: In this paper, the insects and mites in two different sized
saltcedar woodlands in Fukang (larger size) and Hutubi (smaller size) in the
northern Xinjiang of West China were surveyed over the season. There were
approximately 100 species in 50 families and 11 orders. According to the
trophic level and feeding mode, seven guilds were established, i.e., predator,
parasitoid, strip-feeder, sap-sucker, gall-maker, flower-and seed feeder, and
tourist. The species richness in Fukang was higher than that in Hutubi (81 to
71), with 53 species shared by both sites, but species proportion in each guild
was similar at both sites. Predators, strip-feeders and sap-suckers contained
more species, with each accounting for 1.15 of total species. Sap-suckers and
gall-makers were most abundant, followed by strip-feeders. Most abundant
species were Adiscodiapis tamariciocola (Diaspididae), Aceria tamaricis
(Eriophyidae, Acarina), and Psectrocema barbatum (Cecidomyidae),
whose numbers accounted for > 25% of total individuals for each species,
followed by Diorhabda elongata deserticola (Chrysomelidae), Coniatus
steveni (Curculionidae) and Ornitholvolva heluanensis
(Gelechiidae), whose numbers accounted for 5[approximately]10% of total
individuals for each species. The Pielou's evenness and Shannon-Wiener
diversity indices of insect communities were greater in Fukang woodland than
those in Hutubi woodland during early and mid seasons, but less than those in
Hutubi woodland during the later season. The Berger-Parker dominance index of
insect community in Fukang was smaller than that in Hutubi.

(2,3,4,4-Tetramethylcyclopentyl)methyl acetate, a sex pheromone from the
obscure mealybug: First example of a new structural class of monoterpenes.
Journal of Chemical Ecology 31(12): 2999-3005. Notes: The sex pheromone of the
obscure mealybug, Pseudococcus viburni, consists of
(1R*,2R*,3S*)-(2,3,4,4-tetramethylcyclopentyl)meth yl acetate, the first
example of a new monoterpenoid structural motif in which the two isoprene units
forming the carbon skeleton are joined by 2'-2 and 3'-4 connections rather than
the usual 1'-4, head-to-tail connections. This highly irregular terpenoid
structure, and the irregular terpenoid structures of related mealybug species,
suggest that these insects may have unique terpenoid biosynthetic pathways.

Armored Scale Insect Pests of Trees and Shrubs Ithaca, NY: CornellUniv.
Press. 442 pp. Notes: Armored scale insects are among the most damaging and
least understood of the pests that prey on forest trees, fruit and nut crops,
landscape ornamentals, and greenhouse plants. The passage of U.S.
plant quarantine laws was prompted by devastation caused by an armored scale in
the nineteenth century, and the appearance of new invasive species remains a
vital concern at ports of entry and for arborists, farmers, nursery workers,
foresters, and gardeners everywhere. This book provides the most comprehensive
available information on the identification, field appearance, life history,
and economic importance of the 110 economically important armored scale insects
that are found in the United
States. The authors have devised the first field
key to economic armored scales, which will be invaluable to those trying to
identify the pests and prevent the introduction of new exotics. (Most of the
species covered are not native to the United
States but broadly distributed across the
globe.) The extensive color plates and highly detailed line drawings surpass
anything available in other volumes on armored scale insects, and have not
previously been published. Especially noteworthy are the data on distribution,
host plants, and the kinds of damage caused by armored scales. The species
descriptions include scientific names, synonyms, common names, field
characteristics, microscopic characters, affinities, host plants, distribution
by state, life history, economic damage, and selected references.

parasite insects is reported. The main predators of the mealybugs are
Coccinellidae, particularly Scymnus couturieri. Among the
parasites, the most numerous are Encyrtidae. Some, such as Epidinocarsis lopezi [Apoanagyrus
lopezi], directly attack mealybugs and are thus useful assistants.
Others live as parasites on predators or parasites of mealybugs and so reduce
the efficiency of those assistants. In addition, some other insects, whose role
is not yet known, are also present. The paper presents the relative abundance
of all the collected species.

tenuivalvata (Newstead) in sugar cane fields. (In English with summary

Population estimation of P. tenuivalvata was done in
different sites of the cane field, i.e. east, north, south, west and field
centre, in Giza, Egypt.
Insect density proportionally increased from May to December in all field sites
and the scales became intensive throughout September-November. The plants
located in the west site intensively harboured the highest population of scales
followed by the north site. The number of scales on the plant - east and south
sites were approximately similar. Centre site had the lowest number of insects.
Plant infestation decreased as the distance between plant location and field
border increased, so cane plants nearby the field border were heavily infested
than plants far from the field border. At the same time, the lower part of the
cane plant seems to be the poorest site for insect location and feeding while
the middle was the most favourable site followed by the upper part of the cane
plant. P. tenuivalvata preferred the lower surface of cane leaves for
settling and feeding. Nymph and adult stages showed clear preference to
north-western direction of sugarcane field where its population was always
abundant throughout the season.

phylogenetic study of armoured scale insects (Hemiptera: Diaspididae).
Systematic Entomology 31(2): 338-349. Notes: [DOI
10.1111/j.1365-3113.2005.00316.x] Armoured scale insects are economically
important parasites of woody plants and grasses. They are promising subjects
for the evolutionary study of physiology (no complete gut), genetics
(chimerism, paternal genome elimination, frequent parthenogenesis) and
coevolution (with host plants, parasitoids, Septobasidium fungi, endosymbiotic
bacteria). Little phylogenetic work has been accomplished with armoured scales,
and uncertainty surrounds their classification. Here, we report the
phylogenetic results of Bayesian and parsimony analyses of 705 base pairs of
Elongation Factor 1a and 660 base pairs of 28S from eighty-nine species of
armoured scale insects, representing forty-seven genera and five tribes in the
subfamilies Diaspidinae and Aspidiotinae, together with two outgroups. 28S was
aligned based on a secondary structural model. Our results broadly corroborate
the major features of the existing classification, although we do not find
perfect monophyly of any of the traditionally recognized subfamilies or tribes.
The subfamily Aspidiotinae is paraphyletic with respect to the subfamily
Diaspidinae. Diaspidinae consists of two main clades that only roughly
correspond to the tribes Lepidosaphidini and Diaspidini. Diaspidini is nearly
monophyletic, except that it includes a single aspidiotine species. Other
members of the tribe Aspidiotini form a clade, except that the clade includes a
single species of Leucaspidini and excludes Maskellia and Pseudaonidia. Our results
weakly support the hypothesis that the most recent common ancestor of the
Diaspididae had adult females that were permanently enclosed within the derm of
the second instar (the pupillarial habit) and had diploid adult males that
eliminated their paternal genomes during spermatogenesis (late paternal genome

during 2000/03 in Kenya to assess the impact of D-C Tron Plus, an
oil-formulated insecticide (Petroleum spray oil), on the management of coffee
green scale, Coccus alpinus, and to evaluate its ability to sustain and
conserve the biological control agents of this pest, particularly the predators
(ladybirds) and parasitoids. Three rates of D-C Tron plus; 50, 100 and 200
ml/20 litres of water were assessed. The untreated plots were incorporated as
the control. The three rates significantly managed the green scale infestations
as compared with the control. The same rates and the control, when compared
with the banded coffee trees, showed significantly equal levels of mean number
of ladybirds per tree and parasitism, thus indicating the sustainability of the
biological control agents. The findings from this study indicated the
suitability of D-C Tron Plus as a biorational pesticide in integrated pest
management programmes in coffee farming in Kenya.

Schauff (Hymenoptera: Encyrtidae) totaling 24,586 were imported from Puerto
Rico and field released in Palau from
August 2003 to June 2004. Anugyrus loecki and A.
papayae appear to be promising biological control agents of PM in Palau. No
field recovery of P. mexicana was made in spite of several field releases. The
reduction of the papaya mealybug population density levels below detectable
levels was observed in a six-month period following the introduction of these
exotic parasitoids. Following the successful implementation of a classical
biological control program, the risk of this mealybug spreading to other
islands in the Republic of Palau and
to neighboring MicronesianIslands has
been considerably reduced.

Host suppression and stability in a parasitoid-host system: experimental
demonstration. Science 309(5734): 610-613. Notes: We elucidate the mechanisms
causing stability and severe resource suppression in a consumer-resource
system. The consumer, the parasitoid Aphytis, rapidly controlled an
experimentally induced outbreak of the resource, California red
scale, an agricultural pest, and imposed a low, stable pest equilibrium. The
results are well predicted by a mechanistic, independently parameterized model.
The key mechanisms are widespread in nature: an invulnerable adult stage in the
resource population and rapid consumer development. Stability in this
biologically nondiverse agricultural system is a property of the local
interaction between these two species, not of spatial processes or of the
larger ecological community.

2005. Evaluation of buprofezin for the management of grape mealy bug, Maconellicoccus
hirsutus (Green). Journal of Entomological Research 29(4): 339-344.
Notes: Field experiments were conducted in Tamil Nadu, India, during the 2002
and 2003 rabi seasons, to evaluate the performance of buprofezin at 1125 and
1500 ml/ha in controlling the grape mealybug (Maconellicoccus hirsutus).
The efficacy of buprofezin, as a foliar spray, was also compared to carbosulfan
and chlorpyriphos. Buprofezin reduced the nymphal and adult populations and
bunch infestation of M. hirsutus and increased the fruit
yield compared to untreated controls and recommended insecticides. As the
efficacy of both doses was statistically at par, the lower dose of 1125 ml/ha
is sufficient to effectively mitigate mealy bug colonies. There were no phytotoxic
symptoms observed on any part of the treated plants due to any of the

Respiration by mangrove ants Camponotus anderseni during nest
submersion associated with tidal inundation in Northern
Australia. Physiological Entomology 31(2): 120-126.
Notes: The ant Camponotus anderseni lives exclusively in twigs of the mangrove
alba, which forms the fringe at the wettest part of the mangrove zone.
During inundation, which can last up to 3 h, the entrance hole to the nest
cavity is blocked with a soldier's head that effectively prevents flooding, but
simultaneously blocks gas exchange with the surroundings. The ants and brood,
together with their mutualistic Coccid, Myzolecanium sp. 1, occupy an
average of 23% of the volume of the nest cavities (maximum of 50%).
Measurements of CO SUB 2 production in the laboratory indicate respiratory
rates of 1.90 and 0.41 microL CO SUB 2 h SUP -1 mg SUP -1 live mass at 25(deg)C
for workers and larvae, respectively. Measurements of sealed natural nests show
that mean respiratory rates decrease to 18.9% and 1.8% of the normoxic rate at
CO SUB 2 concentrations of 10% and 25%, respectively. In artificial nests where
the initial CO SUB 2 is elevated, the respiratory rates after 1 h are reduced
to 48% and 2.3% of the normoxic rate when exposed to CO SUB 2 concentrations of
10% and 25%, respectively. Air samples from natural nests in the field taken
more than 12 h after inundation have mean CO SUB 2 concentrations of up to
4-5%, which means that the CO SUB 2 concentration in the parts farthest from
the entrance must be much higher. In sealed nests in the laboratory, the O SUB
2 concentration after 1 h decreases by 6.8% and, in the same period, the CO SUB
2 concentration increases by 12.1%, which suggests that the ants have partly
switched to anaerobic respiration. The rapid and extreme depression of the
respiratory rates of C. anderseni represents an
outstanding physiological adaptation that allows their survival under the
extreme conditions of tidal inundation.

Design and development of power operated roller type lac scraper. Agricultural
Mechanization in Asia, Africa and Latin
America 37(1): 35-37. Notes: Lac is the hardened
resin secreted by the tiny lac insect [Kerria lacca]. Lac insects thrive
only on certain trees called lac hosts. Butea monosperma (Palas), Zizyphus
mauritiana (Ber) and Schleichera oleosa (Kusum) are the
major lac hosts used in India. Lac
cultivation involves five major operations which are pruning, inoculation, used
up broodlac (phunki) removal, harvesting and lac scraping. Mostly, lac
cultivation operations are carried out manually with the aid of locally
manufactured traditional tools. Manual lac scraping is a very slow and tedious
process. In one method, farmers sit on the ground in a group and scrape lac
with the traditional tools like a small scraping knife (dauli) and sickle. In
another method, farmers remove lac encrustation by beating lac sticks with
bamboo stick. One person scrapes 5-10 kg of lac in a day. As scraping is done
on the ground, unwanted foreign materials like sand, soil, and wooden twigs
find their way into scraped lac, reducing the price to farmers and creating
problems during lac processing in industries. In order to increase the output
and reduce the drudgery of lac production, a simple power operated roller type
lac scraper was designed and developed. The machine consists of a scraper,
separation screen, feed hopper, drive mechanism and machine frame. The machine
scrapes lac under the action of shear and compressive forces. One person
operates the machine and scrapes approximately 13.5 kg lac stick h SUP -1 with
a scraping efficiency of 95%.

storage on Anagyrus ananatis Gahan (Hymenoptera: Encyrtidae). Biological
Control 35(1): 9-16. Notes: Studies were conducted to determine the survival
and reproduction of Anagyrus ananatis Gahan (Hymenoptera: Encyrtidae) individuals
following cool storage above and below its developmental threshold (T-o) (12.65
degrees C). When immatures were stored at 14.8 degrees C, they had emergence
rates comparable to the control after 8 weeks, which indicated high survival
rates at that temperature. Storage at 10.1 degrees C was deleterious to
parasitoid survival (17-100% mortality), especially when individuals were
stored without preconditioning. Preconditioning by exposing the individuals to
14.8 degrees C for 1 week before storage at 10.1 degrees C improved parasitoid
survival and fecundity compared to those without preconditioning. Effects were
severe when A. ananatis individuals were stored at 10.1 degrees C while in
the prepupal stage because most failed to develop further. Individuals that
were preconditioned at 14.8 degrees C before being held at 10.1 degrees C
experienced no mortality in the prepupal stage. The I week of storage at 14.8
degrees C allowed all prepupae to develop into the pupal stage before they were
transferred to 10.1 degrees C. Prepupal to early pupal stages can only be
stored for brief periods (< 2 weeks) at 10.1 degrees C because prolonged
exposure is lethal.

Effect of pink pineapple mealybug hosts on Anagyrus ananatis Gahan size and
progeny production. Biological Control 35(1): 1-8. Notes: Studies were
conducted to improve the colony production of Anagyrus ananatis Gahan
(Hymenoptera: Encyrtidae) when reared on the pink pineapple mealybug (PPM), Dysmicoccus
brevipes (Cockerell) (Hemiptera: Pseudococcidae). Parasitization of
large PPM (> 0.85 mm length) by A. ananatis resulted in an almost
3:1 ratio of female:male offspring. A strong positive correlation (r(2) =
0.8935) was found between PPM weight and parasitoid size (i.e., length). Male
parasitoids were not as food limited as females when the mealybug host was
small. Despite the ability of A. ananatis to parasitize all host
stages except crawlers, gravid adult female PPM produced larger parasitoids
with higher fecundity. Allowing PPM to continue feeding on squash following
parasitization produced larger parasitoids. However, for A. ananatis propagation
it is more efficient to remove PPM from squash hosts and size them (via
sieving) before exposing them to the parasitoid. Mealybugs > 0.6 mg in
weight and > 0.5 mm in size can be used for parasitoid rearing to produce
female A. ananatis (> 1.4 min length) that exhibit fecundities
similar to those for A. ananatis that developed on PPM
that fed on squash following parasitization (similar to 28 progeny per female).
Furthermore, to maintain an A. ananatis female-biased sex ratio,
PPM hosts > 0.6 mm (medium size) would be preferable for use in parasitoid
colony production. The length and width of PPM mummies were good predictors of
the sex and body size of the parasitoid contained within, and may be potentially
used as important indicators of parasitoid quality and fitness in a mass

Weeds adjacent to Hawaiian pineapple plantings harboring pink pineapple
mealybugs. Environmental Entomology 35(1): 68-74. Notes: Surveys were conducted
to identify the weeds bordering Hawaiian pineapple plantings that could serve
as hosts for the pink pineapple mealybug, Dysmicoccus brevipes (Cockerell).
Collected mealybugs were held to determine parasitization by the encyrtid Anagyrus
ananatis Gahan. Greater than 15 species of weeds were found around
pineapple plantings in both disturbed (e.g., mowed, herbicide treated, manual
weed removal) and undisturbed areas. Weed diversity was low in the undisturbed
areas with guinea grass, Panicum maximum, being the dominant
species and free of pink pineapple mealybug. Weed species composition was more
diverse in the disturbed areas adjacent to plantings, with routinely mowed
areas being more diverse. Although pink pineapple mealybug is a polyphagous
mealybug, it was only found in moderate densities on rhodesgrass, Chloris
gayana, and wire grass, Eleusine indica, both of which were
found in mowed and unmowed weedy areas with the former species being more
common. All phenological stages of rhodesgrass were infested with pink
pineapple mealybugs, but only mature wire grass plants were infested. None of
the pink pineapple mealybugs collected from the weeds produced parasitoids,
which suggests that the most common weeds found during these studies did not
serve as reservoirs for A. ananatis. Because some common
weed species harbored Dysmicoccus mealybugs, weed
management could play a significant role in reducing pink pineapple mealybug
movement into pineapple plantings.

Enhanced production of pink pineapple mealybug, Dysmicoccus brevipes
(Hemiptera: Pseudococcidae). Biocontrol Science and Technology 16(4): 389-401.
Notes: A mass rearing program was developed for the pink pineapple mealybug
(PPM), Dymsicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae),
to provide host material for producing the encyrtid parasitoid Anagyrus
ananatis (Gahan). PPM individuals produce honeydew that accumulates on
heavily infested squash and entraps crawlers and older instars. A new protocol
was tested to reduce accumulated honeydew with minimal mortality to PPM.
Butternut and kobocha squash were placed in rearing containers and covered with
coarse vermiculite (> 2.36 mm diameter) after being infested with PPM. Use
of vermiculite removed the honeydew from the squash surface. PPM produced using
vermiculite were easily harvested from the host squash, but mealybugs produced
on squash without vermiculite were embedded within the honeydew. When
individual kobocha squash fruit were inoculated with 300-400 mature PPM adults
(> 0.6 mm length), about 700 adult PPM (appropriate for A. ananatis production)
were produced for each dollar value (USA) of
squash fruit (i.e., similar to 1500 PPM per individual squash).

morphological development of Anagyrus ananatis a constant
temperatures. Biocontrol Dordecht 51(5): 585-601. Notes: The lower
developmental temperature threshold (T-0) and the Degree Days (DD) required for
the encyrtid endoparasitoid Anagyrus ananatis Gahan to develop
from egg to adult on the pink pineapple mealybug (PPM), Dysmicoccus brevipes
(Cockerell) (Hemiptera: Pseudococcidae), were determined. The T-0 was estimated
to be about 12.65 degrees C for both females and males. In contrast, females
and males required about 275 and 265 DD, respectively, to complete development
from egg to adult. Temperatures from 19 to 29 degrees C were optimal for mass
rearing of A. ananatis, with the optimal temperature being around 24
degrees C. At this temperature, A. ananatis could complete almost
two generations in the time it takes PPM to complete only one generation.
Although A. ananatis is a koinobiont, the mealybug host was killed
within a few (6-8) days after parasitization. The developmental stages of A.
ananatis were described (e.g., appearance, size, color) and their time
periods quantified when reared on PPM at 23.5 +/- 0.5 degrees C. Encyrtiform
eggs were inserted through the dorsal surface of the PPM and were attached to
the host via a slender stalk. This immature parasitoid remained attached to the
host cuticle via the stalk until entering the prepupal stage. The host mealybug
mummified during the parasitoid's prepupal stage. First adult eclosion occurred
at 24 days post-parasitization.

control on pear primarily focuses on containing few species. Cydia
pomonella is the most dangerous due to either suitable climatic
conditions of the last decade or the occurrence of insect populations resistant
to some of the most commonly used insecticides. Cacopsylla pyri and Quadraspidiotus
perniciosus [Diaspidiotus perniciosus] are also
among the most feared pests and are contained by means of specific chemical
applications. Other species infest the pear orchard occasionally and
insecticide applications are triggered by specific damage threshold. Some of
them occur sporadically close to harvest (Lygus rugulipennis and Ostrinia
nubilalis) or in orchards where environmental friendly pest control
strategies are applied (Stephanitis pyri, Dysaphis pyri, Cossus

complex was carried out from August 2003 to December 2004 in mixed cropping
agroecosystems in 4 areas of northeastern zone of Tamil Nadu, India: Mangadu,
Poonamallee, Padappai and Manimangalam. In all these areas, vegetable crops
such as bhendi [okra], brinjal [aubergine] and radish were cultivated and
border crops such as castor, curry leaf [Murraya koenigii], Sesbania
grandiflora, subabul [Leucaena leucocephala] and Hibiscus
sp. were grown. Groundnut was intercropped with black gram, cowpea and mung
bean. Among the various orders of insect, Coleoptera contributed the maximum
number of predators in all the areas, followed by Odonata. Ladybird beetles,
followed by dragonflies, were found to be the dominant predatory insects. Cheilomenes
sexmaculata and Coccinella transversalis were the
predominant ladybird beetles in all types of crops and were found to be feeding
on aphids, whitefly nymphs, scale insects and mealy bugs.

Climate variables and their role in site discrimination of invasive insect
species distributions. Environmental Entomology 35(4): 958-963. Notes: This
study investigated the influence of climate variables on insect establishment
patterns by using discriminant analysis to classify the climatic preferences of
two groups of polyphagous insect species that are intercepted at New
Zealand's border. One group of species is
established in New Zealand, and
the other group is comprised of species that are not established. The
discriminant analysis classified the presence and absence of most species
significantly better than chance. Late spring and early summer temperatures
correctly classified a high proportion of sites containing the presence of both
established and nonestablished species. Soil moisture and winter rainfall were
less effective discriminating the presence of most of the species studied here.
Cold winter air temperature was also a good classifier for the insect species
that are not established in New
Zealand. This study showed that multivariate
statistical techniques such as discriminant analysis can help distinguish the
climatic limits of insect distributions over large geographical scales.

total, 162 exotic pests have been introduced into the country during this
period. Of these, approximately 130 are presently acclimatized and exhibit a
different distributional range according to their climatic requirements and
host plants. Most are pests of ornamentals (79 species), woody plants (38
species), Citrus (16 species), horticultural crops (15 species), fruit trees
and grapevine (14 species). Most of the introduced species are Hemiptera (64%,
mainly aphids and scale insects), followed by Coleoptera (12%), Lepidoptera
(7%), Diptera (6%), Thysanoptera (3%) and Hymenoptera (2%). Mites account for
6% of the introduced pests. Majority of the alien pests are from the Americas

spp.) with and without infection by Neotyphodium fungal endophytes. New
Zealand Journal of Agricultural Research 48(3):
329-337. Notes: Pasture mealybug (Balanococcus poae) was found
infesting two field trials evaluating the performance of selected strains of
the endophyte Neotyphodium lolii in ryegrass (Lolium spp.) in Canterbury, New
Zealand. Deterioration of endophyte-free plots
relative to endophyte-infected plots had been observed. In Trial A, pasture
mealybug were sampled in plots of the perennial ryegrass cultivar 'Grasslands
Nui', without endophyte (nil), or infected with the wild-type endophyte, or the
selected strains, AR1 and AR37. In Trial B, mealybug numbers on six ryegrass
cultivars infected with AR1 or wild-type were compared with those on the same
cultivars without endophyte. In sampling these trials, the presence of a root
aphid, Aploneura lentisci, was also noted. Populations of mealybug in
both trials were similar on all endophyte-infected treatments and significantly
lower than populations on nil treatments. Neither AR1 nor wild-type appeared to
reduce root aphid numbers, while AR37 may have had some effect. The amount of
dead grass was significantly greater in nil than in endophyte-infected plots in
Trial A, and yield of ryegrass was correlated with numbers of mealybug and root
aphid present. Pasture productivity in nil treatments had recovered by spring,
in the year of the outbreak. The presence of endophyte, strain of endophyte and
cultivar were all significant factors affecting both total dry matter and green
yield in Trial B. Pasture mealybug accounted for 55% of the variation in a
decline in growth rate that occurred in this trial over the summer-autumn
periods between 2000 and 2001, particularly in the nil treatments. Two years
after the outbreak there was 25% less ryegrass and persistently lower pasture
yields in nil plots. We conclude that pasture mealybug are capable of
inflicting severe damage to endophyte-free ryegrass in Canterbury,
particularly during dry summer-autumn periods.

of the appearance of the predator no measures were recommended. In 2005, no
further outbreak was observed.

parasites of European beech (Fagus Sylvatica L.).] Holzbrutende
Borkenkafer als Schadlinge der Rotbuche ([Fagus sylvatica L.). (In German with
summary in English.) Mitteilungen der Deutschen Gesellschaft fur allgemeine und
angewandte Entomologie 15: 225-229. Notes: Since 2001, the infestation of
living beech (F. sylvatica) by the broad-leaved ambrosia beetle (Trypodendron
domesticum; Coleoptera, Scolytidae) is observed (in Germany).
Anatomical and physiological investigations on the infestation clearly show
that there is a susceptibility of beech for the infestation. In the inner bark
of infested beech trees, small extensive necroses were found to be present.
This tissue damage is made responsible for the attraction of the beetles by
alcohol emissions set free. The necroses are the results of feeding damage by
the beech scale (Cryptococcus fagisuga). It is concluded that the infestation
process by beetles and the beech bark disease complex are closely linked.

Podsiadlo, E. 2005b. Morphological adaptations for
respiration in Coccidae (Hemiptera: Coccinea). Polskie Pismo Entomologiczne
74(4): 423-430. Notes: The size of spiracles, of clypeo-labral shield and their
location in relation to each other were analysed in Coccus hesperidum
Linnaeus, Parthenolecanium corni (Bouche), Sphaerolecanium prunastri
(Fonscolombe), Luzulaspis frontalis Green and Scythia
festuceti (Seulc). It is suggested that possessing small spiracles results
from a considerable share of cutaneous respiration in gas exchange. On the
other hand, the presence of large spiracles indicates limited cutaneous
respiration or restricted access of air to spiracles. It has been assumed that
oxygen deficit intensified the activity of mandibulo-maxillary muscles, which through
their contractions and relaxations may stimulate gas exchange. Further, more
intensive work of these muscles causes the development (increase in size) of
clypeo-labral shield which serves as a means for attaching them. Movement of
the mouthparts backwards between anterior and posterior spiracles is probably
aimed at more effective ventilating not only the anterior tracheal trunks but
also the posterior ones.

respiration in Cryptococcidae (Hemiptera: Coccinea) occurring in Poland.
Polskie Pismo Entomologiczne 75(2): 277-281. Notes: The size and location of
spiracles and size of clypeo-labral shield were analysed in Cryptococcus
fagisuga and Pseudochermes fraxini. In these
species, the access of air to spiracles is hindered due to their living in bark
crevices of trees. Morphological adaptation to these unfavourable oxic
conditions is the location of spiracles in deep cavities of sclerotized wall
which, presumably, contain air reserves being the source of oxygen. In both
species, the clypeo-labral shields are very large, which is an adaptation to
feeding in woody parts of plants and to living in unfavourable oxic conditions.

Field evaluation of methomyl against mealy bug, Maconellicoccus hirsutus
(Green) and predatory coccinellid, Cryptolaemus montrouzieri mulsand in
grapes. Pesticide Research Journal 18(1): 28-30. Notes: Bio-efficacy
experiments conducted in two concurrent trials from December to April and April
to August indicate that methomyl (Lannate(R) 40 SP) at 500-800 g ai ha(-1) was
effective in containing the populations of mealy bug, Maconellicoccus hirsutus
on grapes. Methomyl 300-600 g ai ha(-1) registered higher population of
predatory coccinellids than other treatments in both the trials; however, it
was not comparable with untreated check. But better recolonization of
coccinellids was noticed in methomyl treatments than in dimethoate. Methomyl at
500-800 g ai ha(-1) recorded the maximum fruit yield (14-17.5 t ha-1), which
were superior to other treatments including methomyl 300 g and 400 g ai ha(-1)
and dimethoate 300 g ai ha(-1). The methomyl treatments at 500, 600, 700 and
800 g ai ha(-1) gave higher returns in grapevine cultivation with cost-benefit
ratios of 1:14.8, 1:16.5, 1:16.6 and 1: 16.5, respectively, when compared to
dimethoate application and untreated check.

arthropod pests on Kalmegh, Andrographis paniculata - an
important medicinal plant. Insect Environment 11(2): 89-91. Notes: A field
study was undertaken during 2001-02 in Bangalore, Karnataka, India to
record various pests and their seasonal incidence on kalmegh, A.
paniculata. Seedlings were raised in June and transplanted in July at a
spacing of 60x30 cm in 20 beds of 2x2 m SUP 2 size. Observations on pest
incidence and plant parts attacked were recorded from 5 randomly selected beds
(5 plants per bed) at 15 days interval. Brown scale, Parasaissetia nigra, was
found to be causing significant damage, as the affected plants exhibited
stunted growth and drying, followed by semilooper, Panilla sp. nr. albopunctata,
which damaged the plants by feeding on young leaves, flower buds and tender
pods resulting in foliage loss. This is thought to be the first record of
arthropod pests on kalmegh from India.

mealybug in Florida and
the United States.
Stochastic Environmental Research and Risk Assessment (SERRA) DOI 10.1007/s00477-005-0027-0.
Notes: This paper estimates the expected annual impacts of the Pink Hibiscus
Mealybug infestation on the economies of Florida and
the rest of the United States. The
approach involves a Markov chain analysis wherein both short run and long run
expected damage from infestation are calculated. Use is made of the CLIMEX
model that predicts the potential pest-establishment regions in the U.S.
While predictions based upon the CLIMEX model extend the scope of damage beyond
damage is significantly dependent upon the rate of arrival and detection of
species in those regions. Damage is significantly higher when a longer time
horizon is considered. When nursery owners bear the full cost of quarantines in
the form of loss of sales and treatment costs of infected plants, the
cost-effectiveness of quarantines as a regulatory tool is diminished. The long
run propensity of the system, in terms of the fraction of time spent in the
possible 'states' of infestation and control, determines the extent of damage,
and not the annual value of crops that could be potential hosts to the pest.

Novel technique to increase the shelf life of cassava (Manihot esculenta L.)
stems stored for propagation. Advances in Horticultural Science 19(3): 123-129.
Notes: Healthy, mature stems approximately 1.2-1.5 m long from 3 cassava
cultivars (Sree Prakash, Sree Jaya and H-165) were stored for 5 months under
hot, dry weather conditions under seven treatments: T SUB 1 - stems stored vertically
under tree shade; T SUB 2 - stems stored vertically under tree shade and
watered at 15-day intervals; T SUB 3 - stems stored vertically under tree shade
with bottom portion (2-3 cm) buried in sand bed and watered at 15-day
intervals; T SUB 4 - stems stored horizontally under tree shade; T SUB 5 -
stems stored vertically in the open; T SUB 6 - stems stored vertically in the
open and watered at 15-day intervals; and T SUB 7 - stems stored vertically in
the open with bottom portion (2-3 cm) buried in sand bed and watered at 15-day
intervals. Insecticide chlorpyrifos (active ingredient (a.i.) 20%) was applied
to all stems to protect them from termite (Odontotermus sp.) and soft scale (Aonidomytilus
albus) infestation. Fungicide carbendazim (a.i. 50%) was applied to
stems stored in treatments T SUB 1, T SUB 2, T SUB 3, T SUB 5, T SUB 6 and T
SUB 7, whereas mancozeb (a.i. 75%) was applied to stems stored in treatment T
SUB 4 to protect them from any fungal infection. Stems of the three cassava
cultivars in treatments T SUB 3 and T SUB 7 retained greater moisture content
(68.8-71.0%), greater percentage of fresh stem (90.0-91.7%), had greater starch
content (256.3-269.9 mg/gram dry stem), and showed greater percentage of
sprouting (90.7-95.3%). Plants from these stems showed a lower reduction in
storage root yield (2.6-3.6 t/ha) as compared to storage root yield of plants
from fresh stems. It is recommended that cassava stems be stored vertically
with bottom portion (2-3 cm) buried in sand bed and watered at 15-day intervals
under open conditions with appropriate plant protection measures over a period
of five months under hot, dry weather conditions.

Influence of floral resource plants on control of an armored scale pest by the
parasitoid Encarsia citrina (Craw.) (Hymenoptera: Aphelinidae). Biological
Control 37(3): 320-328. Notes: We tested the hypothesis that control of an
herbivorous pest would be improved by providing floral resources for adult
natural enemies. The herbivore was euonymus scale, Unaspis euonymi
(Comstock) (Homoptera: Diaspididae), a serious pest of woody ornamental plants.
The experimental landscape consisted of 3x3 m plots, each containing a central
bed of Euonymus fortunei (Turcz.) that was infested with the scale.
Floral resource plants were cultivars of four species that overlapped in bloom
periods to provide a continuous supply of floral resources during summer: Trifolium
repens L., Euphorbia epithymoides L., Coreopsis verticillata L. var. 'Moonbeam,'
canadensis L. var. 'Golden Baby.' Plots contained either low or high
densities of all four species, or no resource plants. Densities of euonymus
scale were typically lower in plots containing resource plants than in plots
without them. Parasitism by Encarsia citrina (Craw.)
(Hymenoptera: Aphelinidae) was rarely influenced by the experimental
treatments, flower biomass, whole-plant biomass, or scale density, but in some
cases was inversely correlated with density of scales within a generation and
in the subsequent generation. Parasitism occasionally reduced densities of
scales in plots containing resource plants, but this effect apparently was
related to vegetative, not floral qualities of plants. A steady increase in
parasitism rate over the three-year course of the experiment across the entire
landscape was associated with decreasing density of scales, suggesting a
numerical response by the parasitoid population. These findings suggest that
the parasitoid is capable of effectively controlling euonymus scale in
ornamental landscapes where environmental conditions are favorable.

Systematic notes and a detailed description of Opuntia ficus-indica (L.)
Mill. (Cactaceae). Agrociencia 39(4): 395-408. Notes: Opuntia ficus-indica is
the cactus species with the highest economic importance worldwide. It is
cultivated for its fruits, forage, or as host of the cochineal insect, but only
in Mexico are
their young cladodes consumed as vegetables. The main goals of this study were:
a) to integrate systematic notes about its common nomenclature, origin,
reproductive biology and ploidy levels of O. ficus-indica; b) to present a
complete botanical description based on specimens collected in north-central Mexico; and
c) to discuss the taxonomical relationships with other Opuntia species to which
it has been associated. This cactus is native of Mexico,
where the highest cultivar richness is found. From a cytogenetic standpoint,
specimens with varying ploidy levels have been identified and reproduction is
sexual and propagate asexually, the latter being the most extensively used for
cultivating. Samples from 72 different cultivars were collected from 17
locations across eight Mexican States. There seems to be evidence to support
the fact that O. ficus-indica is a different species from O.
amyclae, O. megacantha and O. streptacantha.

some commercial organic formulations against guava scale insect, Pulvinaria

327-331. Notes: The bio-efficacy of two commercial organic formulations neem
spray Aza-3000 EC and DC tron-plus, a petroleum product, was evaluated against
guava scale insect Pulvinaria psidii [Chloropulvinaria psidii] at a
farmer's field in Ghoragachha village in Nadia, West Bengal, India, and
compared to Metasystox [demeton-S-methyl] 25 EC widely used by guava farmers to
suppress populations of the same pest. Both neem spray Aza-3000 EC and DC
tron-plus were given at 2.0, 3.0 and 4.0 ml/litre of water, while Metasystox 25
EC was given at 1.0, 1.5 and 2.0 ml/litre of water. Befitting with the pest
activity, two rounds of sprayings with all the formulations were given, i.e.
one on 8 May 2004 and
the other on 24
May 2004. Neem spray Aza-3000 EC and DC tron-plus
at all rates were as effective as Metasystox 25 EC, producing a remarkable
reduction in the population buildup of P. psidii (82.00-93.00%) over the
control at 10 days after sowing (DAS). Sooty mould, which developed on the
leaves due to the secretion of honeydew by the scale insect, was also
eliminated after 7-10 DAS with these two organic formulations. Hence, neem
spray Aza-3000 EC and DC tron-plus at 2-3 ml/litre of water may be appropriate
for the protection against P. psidii.

Effects of low temperatures on Chilocorus kuwanae (Coleoptera:
Coccinellidae) trophic activity. European Journal of Entomology 103(3):
547-551. Notes: Chilocorus kuwanae Silvestri is an effective predator of Unaspis
euonymi (Comstock), a scale insect harmful to spindle trees (Euonymus
europeus L. and E. japonicus Thumb). The feeding
behaviour was studied on wild adults, collected from spindle trees in the
Botanic Garden of Perugia University, and fed on overwintering U.
euonymi females. The insects were exposed to gradually changing
constant temperatures (13[degree] [forward arrow]10[degree] [forward arrow]
8[degree] [forward arrow] 6[degree] [forward arrow] 4[degree] [forward arrow]
2[degree] [forward arrow] 13[degree] [forward arrow] 15[degree]C) for a ten day
period at each temperature. C. kuwanae adults preyed on the
scale also at low temperatures. The number of scales eaten decreased with
decreasing temperatures from the initial 13[degree]C to 4[degree]C, and at
2[degree]C the trophic activity of C. kuwanae adults almost stopped
although they made brief walks in the petri dishes. At all tested temperatures
the ladybirds made holes in or lifted the scale cover and preyed on the female.
Sometimes they lifted the scale cover, but did not prey on these U.
euonymi females which were destined to die from cold. As the
temperature dropped from 13[degree]C to 40[degree]C, the number of females
eaten by ladybird males and females did not differ statistically. When the
temperature was raised to 13[degree]C and 15[degree]C, the ladybirds resumed
feeding. Large differences were recorded between sexes, with females showing a
much higher feeding activity than males. Scale cover lifting was most frequent
at the beginning of the experiment and then decreased with diminishing
temperatures, although no significant difference was recorded among
temperatures within the range from 10[degree]C to 4[degree]C. The threshold for
trophic activity can be taken as 2[degree]C since we noted that a few (12%)
individuals on one day showed predatory activity. At 13[degree]C and
15[degree]C lifting activity rose again but remained at a lower level than at
the initial exposure to 13[degree]C. There was no significant difference in
activity at 13 and 15[degree]C upon raising the temperature. As for total
number of U. euonymi damaged by C. kuwanae the trend in damage
revealed the same pattern as for number of scales eaten. At the final exposure
to 15[degree]C, 60% of C. kuwanae females laid eggs. Our
data demonstrate that C. kuwanae can reduce U.
euonymi populations in a submediterranean environment even in winter
when the range of temperatures is similar to that tested in this experiment.

develops on the prickly pear cactus (Opuntia ficus-indica), and is
exploited for its capacity to produce natural dyes such as carminic acid (CAC).
Cochineal insects were introduced in Chile in
1989, and exports of dry cochineal began in 1994 and grew to cover 15% of the
world market. However, the current price of dry cochineal is nearing production
costs. Hence, it is necessary to increase yields without increasing costs. A
study was conducted to evaluate the effect of biotic factors on the
concentration of CAC in cochineal insects. CAC was positively affected by the
density of cochineal insects around the plant, plant age, and by the
nutritional status of the plant, and was negatively affected by the age of the
cladode. Additionally, CAC was significantly affected by season: 16.9% of dry
weight in the autumn and 19.1% in the spring. This knowledge may be used in
designing cultural strategies to increase CAC accumulation in cochineal

Local identification and valuation of ecosystem goods and services from Opuntia
scrublands of Ayacucho, Peru.
Ecological Economics 57(1): 30-44. Notes: Opuntia scrublands are important
ecological-economic systems in the Andean area. They perform a major role
protecting slopes against erosion, improving the soil properties and providing
a variety of products employed in the human diet, and in animal feeding, as
well as cochineal insects, a highly valued source of dyes. The collection of
the insects has represented an important economic activity for the local
communities since pre-Columbian times. Current Peruvian production represents
between 85% and 90% of the global market, and is mainly based on collection of
the insect in natural Opuntia scrublands located in the
poorest Andean areas of Ayacucho. Although much is known about the financial
benefits of cochineal for exporters and dye manufacturers, information about
the value of standing Opuntia scrubs to collectors and the
relative contribution of Opuntia scrubs to their household
economies is scarce. This paper contributes to the estimation of the use value
scrublands to local communities in Ayacucho by initially exploring the cultural
domain of Opuntia in order to identify the ecosystem goods and services
recognized by peasants, and later presenting empirical estimates of their
importance to annual household income.

Carrera, K. 2006. Classical biological control of the pink hibiscus mealybug, Maconellicoccus
hirsutus (Green), in southern California.
Biological Control 37(2): 155-166. Notes: A cooperative classical biological
control project against the pink hibiscus mealybug, Maconellicoccus hirsutus
(Green), infestation in the low-desert region of California was
initiated in the fall of 1999. Subsequently, the parasitoids Anagyrus
kamali Moursi (Encyrtidae), Gyranusoidea indica Shafee, Alam
& Agarwal (Encyrtidae) and Allotropa sp. nr. mecrida
(Walker) (Platygastridae) were reared and released for permanent establishment.
Population densities of mealybug and percent parasitism were monitored at a
number of mulberry tree and carob tree sites for five consecutive years. The
population density of M. hirsutus within the first year
was reduced by approximately 95%. Over the entire 5-year period of the project,
the average regional population density of the mealybug exhibited a continued
decline. Anagyrus kamali was the predominant parasitoid, often
parasitizing in excess of 50% of the mid-to-late stage M. hirsutus in the first
2 years following the parasitoid's release. Although Gyranusoidea indica was
rarely found from spring through early fall, it did represent 40% of the
parasitoid species composition during winter. By 2005, the platygastrid
parasitoid, Allotropa sp. nr. mecrida did not appear to be
established following numerous releases in 2003 and 2004. Hyperparasitism of A.
kamali by resident species (Marietta sp.;
sp.) was frequently over 35% during 2000. However, hyperparasitism was
considerably lower during each successive year, coincident with declining
densities of both mealybug and the primary parasitoid host. Field collections
of two other species of mealybugs common in Imperial
Valley demonstrated that they are not being
utilized as alternate non-target hosts by the newly introduced parasitoids.

incidence of pest and disease were conducted at Pune and Padegaon during 2001
to 2003 for suru and preseasonal conditions to develop a model for predicting
the incidence of pests and diseases. It was seen that ESB pest build up started
from 11th MW reached its peak in 15th and 17th MW for treated and untreated
plots, respectively, for preseasonal crop at Pune. Ranges of different weather
parameters, at Pune, for pest build up were Tmax - 34.0 degrees C - 39.0
degrees C. Tmin -17.6 degrees C - 23.2 degrees C, RH 1-51%-69% and RH II - 20%
- 22%. soil temperature - 22.0 degrees C - 28.8 degrees C. Linear regression
model for 15 MW which predicts the incidence of ESB nearer to the observed
values was developed. Mealybugs are among the pests mentioned.

Role of olfaction in host selection by Pseudaphycus maculipennis
(Hymenoptera: Encyrtidae). New
Zealand Plant Protection 58: 311-314. Notes: The
volatile stimuli for host finding by Pseudaphycus maculipennis were
examined in a Y-tube olfactometer. The responses of naive female parasitoids
(2-3 days old) to two mealybug species, Pseudococcus viburni (obscure
mealybug) and Pseudococcus longispinus (longtailed mealybug) on sprouting
potato were measured. The percentage of parasitoids to choose the odour-laden
arm compared to clean air was similar for both mealybug species on potato
sprouts (80 to 82.5%). When given a choice between mealybug species on potato
sprouts, the parasitoid preferred the obscure mealybug. The parasitoids also
responded to an excised sprout from an uninfested potato when compared with
clean air. Further choice tests showed that honeydew secreted by either
mealybug species was similarly attractive, while honeydew was more attractive
than the ovisacs from obscure mealybug. This work shows that P.
maculipennis exhibits a strong response to the plant of their host and
prefer obscure mealybug to longtailed mealybug despite a similar response to
honeydew from both species.

Schuster, T.D., Cobb, N.S., Whitham, T.G.&Hart, S.C.2005. Relative importance of environmental
stress and herbivory in reducing litter fall in a semiarid woodland. Ecosystems
8(1): 62-72. Notes: We examined the impact of soil stress (low water and
nutrient availabilities) and two keystone insect herbivores on pinyon pine (Pinus
edulis) needle litterfall. We compared trees growing on two distinct
soil types: volcanic cinders, which exhibit pronounced water and nutrient
limitation, and sandy-loam soils, which have higher water-storage capacity and
nutrient availability. Using two long-term herbivore removal experiments (15
and 18 years, respectively), we also examined the effects of the pinyon needle
scale (Matsucoccus acalyptus, which attacks juvenile trees) and the
stem-boring moth (Dioryctria albovittella, which attacks mature trees) on pinyon
litterfall. These herbivores reach high densities on cinder soils but are
absent or occur at much lower levels on sandy-loam soils. Four years of
litterfall measurements showed four major patterns. First, independent of
herbivory, needle litterfall was 20% lower under trees on high-stress cinder
soils than on sandy-loam soils. Second, in agreement with the negative impact
of scales on tree growth (that is, a 30% decline in stem growth), trees with
scale infestations had 25% lower litterfall rates than trees resistant to
scale; however, 15 years of scale-insect removal did not significantly increase
needle litterfall. This implies possible intrinsic differences in litter
production between scale-resistant and scale-susceptible trees. Third, in
contrast with significant negative effects of moth herbivory on tree growth
(that is, a 27% decline in stem growth), moth herbivory had no effect on needle
litterfall. This, along with increased stem density in moth-susceptible trees,
may be evidence of compensatory production.Fourth, there were strong year by soil type and year by scale herbivory
interactions, such that in some years the effect on litterfall can be obscured
or reversed by some other factor. In summary, soil stress has a strong and
predictable effect on needle litterfall, whereas the relationship between
insect herbivory and need le litterfall is weaker and depends on the individual
herbivore. These effects, however, are mediated by other environmental factors
that have considerable annual variation.

Inter and intra-colonial recognition of nest and nest-mates by Microcerotermes
beesoni Snyder (Isoptera: Termitidae). Indian Journal of Forestry
28(3): 301-305. Notes: Each colony of the termite has its own peculiar odour.
Every member of the colony recognizes this odour and avoids entering in the
nests of other colonies. Experiments were undertaken to alter the memory of
colony odour of the termite M. beesoni. The memory of colony
odour cannot be easily altered, however, if slightly reduced by some technique,
resulted in the dullness or death of the termites. Colony odour seems to be
genetic in origin and environment probably does not play any role in its development.

teak in Assam.
Insect Environment 11(1): 31-32. Notes: Teak (Tectona grandis) is an
important timber tree and nearly 280 insects have been found associated with
teak all over the country. The scale insect Icerya aegyptiaca
(Margarodidae; Homoptera) was found on teak during 2003 in Jorhat, Assam, India. A
survey was conducted on 50 teak clones collected from various states for any
insect pest or disease incidence from April 2003 to December 2004. A sudden
incidence of the teak scale insect, I.
aegyptiaca, was noticed on several teak clones during July and August 2003.
A total of 6 clones were found heavily infested, followed by 8 clones which were
moderately infested. Out of 50 clones, 27 clones were found less infested with
scale insect as per Rohrmoser severity scale. A total of 9 clones were not
infested with the teak scale insect. After 6 months, data were collected on
growth parameters, such as length and girth (10 cm above the ground level), to
test the performance of different clones. It was found that growth was reduced
due to the scale insect infestation.

Laboratory study of life cycle and feeding rate of the beetle Cybocephalus
fodori minor (Col.:
Cybocephalidae) predator of pistachio oyster shell scale Lepidosaphes pistaciae
(Hom.: Diaspididae). (In Persian with summary in English.) Journal of Science
and Technology of Agriculture and Natural Resources 10(2): 255-267. Notes: The
predatory beetle C. fodori minor has recently been reported in Iran.
Also few studies have been reported on life cycle of Cybocephalus beetles,
especially on that of C. fodori minor. Thus, the life
cycle and feeding rate of this predatory beetle was studied on pistachio oyster
shell scale, L. pistaciae, under laboratory conditions (at 25+/-2(deg)C,
65+/-5% relative humidity and 16:8 (light:dark) h photoperiod). The life cycle
fodori minor was completed at six stages including egg, three larval
instars, pupa and adult. The duration of the development for one generation
(not considering preoviposition period) was 43-46 days for males and 38-42 days
for females. The developmental time length for the egg, larval instars 1-3,
pupa, male and female adults longevity, preoviposition and postoviposition
periods was 8.8+/-0.1, 5.2+/-0.1, 34+/-0.1, 6.8+/-0.1, 17.3+/-0.3, 59.2+/-2.2,
65.8+/-3.1, 6.8+/-1.6 and 3.5+/-0.5, respectively. The average fecundity (number
of eggs laid by a female per her life time) was 64.7+/-6.2. The sex ratio in
the laboratory and in the field was 1:1. The daily feeding rate for the female
and male adults, larval instars feeding on adult female scale was 7.1+/-3.5,
6.9+/-2.2, 1.8+/-0.2, 3.7+/-0.2 and 5.9+/-0.3, respectively. These parameters
were also determined when those stages were fed on the eggs and second nymphal
stages of pistachio oyster shell scale. Adult beetles over 60 days exhibited
the highest feeding on this scale.

Analysis of factors responsible for low yield of lac in India.
Journal of Applied Zoological Research 16(1): 95-96. Notes: Though a single lac
insect (Kerria lacca) has a potential to multiply by 250 times in one
generation, actual seed (broodlac) to yield (lac-produced) ratio is very low.
Single cell cultures maintained on Flemingia macrophylla in the
laboratory yielded 56-175 times more lac that was reduced to 45-50 times in the
field. When the mode of infestation was changed to mass inoculation and the
scale of operation was increased, the yield was drastically reduced to 3, 4 and
7 times of the input on Butea monosperma, F. macrophylla and
mauritiana, respectively, for rangeeni strain; and 5, 9 and 14 times,
respectively, on F. macrophylla, Z. mauritiana and Schleichera oleosa for
kusmi strain during rainy/winter season crop under field condition. With up
scaling of lac culture operations, quantitative and qualitative loss of
broodlac, damage due to pests and management of lac insect population on the
host plant became critical factors affecting adversely the lac crop.

supplement No.3, Volume I). Muzaffarnagar, India:
Uttar Pradesh Zoological Society.Notes:
Silkworms (Bombyx mori) feed on mulberry (Morus spp.) leaves during
their entire larval period and utilize the leaf proteins for the biosynthesis
of silk. It is therefore clear that mulberry plays dominant role in cocoon
production as a source of nutrition to the silkworm. Mulberry foliage is
vulnerable to various pathogens and pests. The pests not only reduce the yield
but also alter the biochemical components. Although the study undertaken on
these aspects is meagre, the findings support the fact that if silkworms are
fed with pest-infested leaves of mulberry cultivars, which are obviously
nutritionally inferior, it leads to crop failure. Many biochemical components
such as total proteins, total soluble sugars, total reducing sugars, starch,
free amino acids, photosynthetic pigments and some micro- and macroelements analysed
in the pest-infested leaves showed either increase or decrease compared to
healthy leaves. The enzymes protease [proteinase], amylase and nitrate
reductase showed a significant variation. The growth and development of
silkworms were also found to be affected when they were fed with pest-infested
mulberry leaves. This review focuses on 5 major pests, i.e. mealy bug (Maconellicoccus
hirsutus), spiralling whitefly (Aleurodicus disperses), jassids (Empoasca
flavescens [ Empoasca vitis]), thrips (Pseudodendrothrips mori)
and leaf roller (Diphania pulverulentalis).

Samples of parasitized aphids and scale insects were collected in different
plant hosts nearby citrus orchards in three different places, in TerceiraIsland (Azores),
namely, Biscoitos, S. Sebastiao and Terra-Cha, aimed at finding plant species
that can provide alternative hosts for parasitoids of citrus pests. Emerged
parasitoids consisted mainly of braconids, i.e., Lysiphlebus fabarum (Marshall),
testaceipes (Cresson) from Aphis fabae Scopoli in Pittosporum
undulatum and Banksia sp., and Aphidius
funebris (Mackauer) from Uroleucon sonchi (Linnaeus), in Sonchus
sp. One specimen of both Aphelinus chaoniaWalker and Microterys
nietneri (Motschulsky) from Coccus hesperidum in Hedera
obscura emerged from Parasaissetia nigra (Nietner) in P.
undulatum and also Moranila californica (Howard).
Secondary parasitism of the pteromalid Pachyneuron aphidis (Bouche) was
also collected from Aphis solanella, in Solanum nigrum L. These parasitoid
species are reported for the first time from the Azores.

Laboratory trials were conducted to test the side-effects of 5 insecticides,
Etifos M (chlorpyrifos-methyl), Applaud (buprofezin), Admiral (pyriproxyfen),
Laser (spinosad) and Biolid E (narrow range mineral oil) on 4 parasitoids of
citrus scales: Aphytis melinus, Coccophagus semicircularis, Coccophagus lycimnia
(Hymenoptera: Aphelinidae) and Leptomastix dactylopii (Hymenoptera:
Encyrtidae). The tests were conducted using a spray PotterTower
following the standard principles accepted by the IOBC/WPRS Working group
"Pesticides and Beneficial Organisms". Contact toxicity on adults
after 24, 48 and 72 h as well as fertility, sex ratio and fecundity of the
progeny were observed. A test was also carried out spraying citrus mealybug
mummies parasitized by L. dactylopii. Total mortality
(100%) of all tested parasitoids due to contact toxicity was observed 24 h
after the treatment with chlorpyrifos-methyl and spinosad. The mean levels of
mortality obtained after 72 h on C. semicircularis and L.
dactylopii were 76 and 58%, respectively, after treatment with mineral
oil. Buprofezin after 72 h caused 95, 100, 42 and 76% mortality on C.
semicircularis, C. lycimnia, L. dactylopii and A. melinus, respectively.
The other IGR (pyriproxyfen) caused lower mortality rates (88% on C.
lycimnia, 48% on L. dactylopii and 62% on A. melinus).
The average number of progeny per single L. dactylopii surviving female was
13.45+/-4.10 (buprofezin), 13.67+/-9.61 (mineral oil), 10.83+/-5.67
(pyriproxyfen) and 15.09+/-10.35 (untreated control) with no statistically
significant differences. The sex ratio of the progeny (M:F) was 0.8:1
(buprofezin), 2.6:1 (mineral oil), 1:1 (pyriproxyfen) and 0.8:1 (untreated
control). The surviving A. melinus females produced a mean
number of progeny of 3.75+/-0.35 (buprofezin), 36.04+/-4.20 (pyriproxyfen) and
36.44+/-2.42 (untreated control) with the first value significantly different
from the others. The sex ratio of the progeny (M:F) was 0.8:1 (buprofezin),
0.6:1 (pyriproxyfen) and 0.6:1 (untreated control). The surviving C.
lycimnia females (pyriproxyfen) did not produce any progeny, while
39.98+/-7.59 mean progeny were produced by the untreated control. Semi-field
and field trials are needed to better define the compatibility of the tested
pesticides with IPM strategies in citrus groves in Italy.

Examining the relative importance of spatial and nonspatial coexistence
mechanisms. American Naturalist 166(4): E75-E94. Notes: Much of the work on
species coexistence has focused on the presence or absence of single
mechanisms. Most theoretical frameworks, however, do not allow one to measure
the strength of coexistence mechanisms, and so it has been difficult to
determine the relative importance of each mechanism when multiple mechanisms
are present. We present a model inspired by the California red
scale (Aonidiella aurantii) system, in which two parasitoids coexist
on a single, tree-dwelling host-scale insect. Previous work suggests that
coexistence may be promoted both by intraguild predation (IGP) and by differing
preferences for hosts on stems versus hosts on leaves (habitat preference). By
applying an analytic framework that quantifies the strengths of spatial
coexistence mechanisms, we are able to measure the individual contributions of
IGP, habitat preference, and their interaction to maintaining coexistence. We
find that habitat preference is much more effective at promoting coexistence in
this model than in IGP. Furthermore, the effects of habitat preference and IGP
are not independent. When the two parasitoids prefer different habitats, the
coexistence-promoting effects of habitat preference are strengthened by IGP if
IGP gives a moderate advantage to the inferior competitor. If IGP either
confers an excessive advantage or favors the superior competitor, it can
diminish the coexistence region.

Optimum sample size and spatial dispersion of red scale, Aonidiella aurantii on an
orange orchard in Australia.
Journal of Asia-Pacific Entomology 9(1): 49-54. Notes: Two-stage sampling and
geostatistical techniques for cost-effective and precise sampling were examined
using red scale data that were collected from a commercial orange orchard in
Kulnura, Australia in mid-summer, 2004 and 2005. The distribution pattern of
red scale on a twig and a fruit well followed the negative binomial, and the
degree of aggregation was higher on a fruit than a twig. The analysis of
variance and two-stage sampling were used to obtain the suitable sample unit (a
leaf, a twig including 2 leaves and 15 cm branch and a fruit in this study) and
optimum sample size. A fruit was the most suitable than any other sample units,
and a twig was better than a leaf. The optimum sample size for twigs and fruits
per tree was 4 twigs (2 leaves and 15 cm branch) and 4 fruits (2 directions), respectively.
The variance of primary sample unit for fruits was higher than that of
secondary sample unit, but that was reversed for twigs. There was a non-linear
relationship between 2 years for the density on 40 fruits of the same tree,
because the Spearman rank correlation coefficient (0.84) was much higher than
the Pearson's (0.29). The spatial continuity for directions of 0[degree],
45[degree], 90[degree], 135[degree], and omni-direction was similar except
90[degree] in which trees were touched with together. The autocorrelation
analysis showed that omnidirectional 10m apart from each sampled tree was
needed to obtain the independent data.

well as on their potential control with releases of the coccinellid predators Rhyzobius
lophanthae and Chilocorus bipustulatus reared in
insectaries. P. oleae was studied in southern Greece,
while Aspidiotus nerii and L. ulmi were studied in central Greece
during November 2001-October 2002. The scales L. ulmi, P. oleae and Aspidiotus
nerii completed one, two and three generations during this period,
respectively. The hymenopterous parasitoid Aphytis mytilaspidis and the
parasitic mite Hemisarcoptes nr. malus were recorded as natural
enemies of L. ulmi. Four natural enemies of Aspidiotus nerii were found,
namely the parasitic wasps Aphytis melinus and Aphytis
chilensis and the coccinelid predators R. lophanthae and C.
bipustulatus, while Aphytis maculicornis, C. bipustulatus
lophanthae acted against P. oleae. Releases of R. lophanthae
bipustulatus were not responsible for the reduction of the population
ulmi, which was due to the activity of the local populations of H.
As for Aspidiotus nerii and P. oleae, the reduction of
infestation level was credited to the activity of R. lophanthae and C.

sp. and C. dicis on flex revoluta, are described from high altitudes on
(Borneo Is.), Malaysia, and
adinandrae is recorded from Sabah and Nepal and
arborea, and Eurya acuminata. The known species
are revised, and their status as species is discussed. Two new genera are proposed,
based on two new species: Kuchingaspis hopeae occurring on Hopea
sp. at Kuching, Sarawak
(Borneo Is.), and Larutaspis lithocarpi associated with Lithocarpus wallichianus
on Bukit Larut, Malaya. Pinnaspis
megaloba Takahashi, 1942, is transferred to Larutaspis on the basis
of the original description. Another species was collected in association with Kuchingaspis
hopeae, and is tentatively placed in Chionandaspis, but it is
not formally named. All the genera treated in this paper belong to the subtribe
Chionaspidina, and are similar in the median trullae prominent and set close,
appressed together, or fused together and the second trullae reduced to very
small pointed processes in the adult female. They distinctly differ in some
other details, and may not be closely related to each other in spite of the
similarity, which should involve convergence and/or parallelism.

Material of dipterocarp-associated gall-inhabiting coccoids collected in Negeri
Sembilan, Malaya (Homoptera:
Coccoidea). Insecta Matsumurana 62: 123-151. Notes: Four species of
dipterocarp-associated gall-inhabiting coccoids were collected in Negeri
Sembilan, Malaya, Malaysia, in
2003 and 2004 in surveys conducted under a project on biodiversity in tropical
forests, and taxonomic accounts of them are given in this paper. One of them, Gallacoccus
longisetosus, sp. nov., is described on the basis of two female and
three male instars. This species is probably rightly referred to Gallacoccus,
and yet peculiar among the known species of the genus in having spinous but
remarkably elongated setae dorsally on the first-instar female. The other
species are also referred to Gallacoccus, but they are not
formally named owing to the insufficient material; instead, they are designated
by tags coined by combining abbreviations of the collection year, locality, and
host plant. One of them is closely similar to G. longisetosus in many
adult male characters, whereas the other two resemble Gallacoccos heckrothi in
the male nymphs or the adult female. Some features and their characters are
discussed with regard to their significance in function and phylogeny: dermal
pits in the first-instar female, legs in the first instar male, penial sheath
pores and other sensilla, and papillae and claws in the adult male. The
discussions remain preliminary, but suggest intricate relationships between
function and phylogeny.

Aphids and scale insects on threatened trees: co-extinction is a minor threat.
Oryx 40(2): 233-236. Notes: Co-extinction is the extinction of a species
following the extinction of another species that it used as a resource, such as
a food plant in the case of insect herbivores. The magnitude of the global
co-extinction threat to two herbivorous insect taxa (aphids and scale insects)
was estimated by compiling a list of species in these groups that are dependent
on globally threatened trees. Eleven species of aphid (0.69%) and thirteen
scale insects (1.15%) have a threatened tree as their sole host. This measure
is comparable to recent estimates for insect herbivores, but far less than the
published overall estimates of extinction risk for invertebrates, and
highlights the dependence of insect herbivores on a wide range of habitat
features. Species mentioned include Mascarenococcus, Chileputo,
Neoplatylecanium, Paralecanium, Richardiella, Lachnodiopsis, Udinia,
Ceroplastes and Dysmicoccus.

Morphological description and illustration of female developmental stages of Stictococcus
vayssierei (Homoptera: Stictococcidae). (In English with summary in
French.) International Journal of Tropical Insect Science 26(2): 126-133.
Notes: The African root and tuber scale S. vayssierei is the only known
hypogeal species of the family Stictococcidae. Its wide range of host plants
together with concurrently field observed differences in host preference
provided evidence of polyphagy or the involvement of more than a single-scale
species. To establish the baseline information for future taxonomic studies,
newly emerged larvae were collected from infested cassava from three sites in
the humid forest zone of southern Cameroon. A
glass binocular magnifier was used to observe morphological changes of live
individuals and slide-mounted individuals of all developmental stages were
examined with a compound microscope. S. vayssierei females went through
three developmental stages, i.e. two larval instars and an adult stage. The
first and second instars were purple-red, while the adult was brown. The body
size and degree of sclerotization of the dorsal line increased in each
developmental stage. White waxy secretions on the basal periphery of the second
instar, and both dorsum and periphery of the adults, distinguished them from
the first instar, which lacks the white waxy secretions. On slide-mounted
specimens, certain aspects of the anal complex (i.e. number of opercular plates
and -setae) were found to be the most discriminating features of S.
vayssierei life stages. These results are useful for further studies on
the diversity of subterranean stictoccocid scales.

Spread of horse chestnut scale (Pulvinaria regalis) in Germany.
Pages 285-286 in Alford, D.V. & Backhaus, G.F. (Eds.), Plant Protection
and Plant Health in Europe: Introduction and Spread of Invasive Species, held
at Humboldt University, Berlin, Germany, 9-11 June 200 Alton, UK: British Crop
Protection Council.Notes: [Symposium
Proceedings NO. 81.] Results are presented of a nationwide survey conducted by
the Plant Protection Service in 2004 on the current status of knowledge
regarding the spread, infestation and management of horse chestnut scale (Pulvinaria
regalis) in some cities and nurseries in Germany. In
recent years, the pest has increased its geographical range and infestations
have also become more severe. The pest is no longer restricted to the major
cities, but has also spread to smaller ones. The pest occurs mainly in urban
locations, rather than in nurseries, where it is an aesthetic problems in green
areas such as city parks. Nevertheless, infestations in nurseries appear to be
increasing, so commercial problems are to be expected. Pest
control on parkland and roadside trees is rarely practiced, even following
infestations of horse chestnut scale. Usually, control measures are taken only
on high quality trees. In general, recommendations and advice for the adoption
of chemical and biological control measures are wanting. Future spread and
infestations can be controlled with the adaption of beneficial organisms
(parasitoids and predators) and strict monitoring and inspection of traded

allgemeine und angewandte Entomologie 15: 143-146. Notes: A thick protective
mass of wax filaments covers each female of the sap-sucking bug, Callococcus

measuring up to 10 mm in diameter, are sometimes abundant in eastern Australia
on the stems of the host plant (Kunzea ericoides), and the wax is of
interest biologically for two reasons. First, unlike many coccid species that
secrete waxy coverings, ants do not attend C. banksiae despite often walking
near them on the plant stems. Second, a particular species of thrips, Teuchothrips
fuscipennis (Moulton) (Phlaeothripidae) breeds beneath the waxy mass,
and the larvae and adults move quickly and freely between the wax filaments
without adhering in any way. The wax surface is the subject of current
investigations, for which this report on taylor-made triglycerides provides a

intertrophic effects detected in 10-year population dynamics of biological
control of the arrowhead scale by two parasitoids in southwestern Japan.
Population Ecology 48(1): 59-70. Notes: Relative effects of weather and
three-trophic interactions were studied for a classical biological control
system consisting of the arrowhead scale Unaspis yanonensis, known formerly
as a serious pest of the Satsuma mandarin orange Citrus unshiu, and its
two introduced parasitoids, Coccobius fulvus and Aphytis
yanonensis. Yearly population responses of the three insect species on
a per-tree basis for up to 10 years at two orange groves were analyzed by
general linear models, with a backward stepwise procedure, to select among
abiotic (summer/winter temperature and rainfall) and biotic (densities of the
three insect species and orange bearing in the previous years) independent
variables. Temperature positively affected the arrowhead scale and the two
parasitoids. A negative correlation of rainfall was detected for all three
insect species. Mandarin fruiting showed negative delayed density dependence,
thereby supporting the observed alternate bearing phenomenon in mandarins,
presumably due to physiological imbalance triggered by climatic factors. The
arrowhead scale was negatively correlated with fruit production in the
preceding years, possibly due to reduced resistance in subsequent years of mast
fruiting. We found a negative correlation of the arrowhead scale with Coccobius
only in a single grove and none with Aphytis. Thus, it appears that
bottom-up forces may be more important than top-down control by the parasitoids
in the post-transient phase of this system.

Cellophane tape with adhesive on both sides to monitor the emergence of
armoured scale crawlers in Eastern Sicily
lemon orchards. Bulletin OILB/SROP (Sect. Reg. Ouest Palearctique) 29(3):

Crops. Proceedings of the meeting of the International Organization for
Biological and Integrated Control of Noxious Animals and Plants, West

September 2005.] Oleander scale, Aspidiotus nerii (Homoptera:
Diaspididae), is a cosmopolitan pest mainly spread in the Mediterranean basin.
This scale insect usually has three generations per year. This corresponds to
three waves of emergence of mobile nymphs, which can be assigned to succeeding
generations. In the spring-summer of 2003, 2004 and 2005, in lemon cv.
Femminello siracusano orchards in eastern Sicily, Italy, we
tested transparent cellophane tape with adhesive on both sides to monitor the
emergence of first instar scales, called crawlers. The crawlers were captured
on the tape as they move across a twig or branch. These tapes were used to
confirm the arrival of the new generation and the beginning of crawler activity
and predict when to manage the Oleander scale. The first generation started in
March-April. Mobile nymphs then moved towards sheltered areas of the tree,
settling preferably on the underside of foliage and fruits. This generation
developed in 8 to 9 weeks. A second generation then occurred in June, taking a
similar amount of time to develop. Insecticide mode of action and formulation
are important because the armor covers and protects all stages but the crawler
and the adult male. Contact insecticides target the crawler stage, such as more
selective horticultural mineral oils. Care must be taken to conserve natural
enemies. Populations of other pests, such as whiteflies, may increase if
insecticides kill their natural enemies. Spray schedules can be determined by
presence of scales in the field rather than by the calendar dates.

piceae is an important pest of spruce. Some biological aspects of the
pest were studied on blue spruce (Picea pungens) in an urban ecosystem
in Ankara, Turkey
during 2001-03. Physokermes piceae has one generation in a year and
overwintered during the second larval stage. These oviparous insects stored
their eggs in 2 chambers under their bodies. Oviposition started in May and
crawlers appeared in the end of June and beginning of July. The second larval
stage occurred in September-May. Adult males and females were observed in the
middle of April up to the middle of June. Males mostly infested the lower
needle surfaces while females preferred the surfaces of young branches. The
ratio of the males in the population was 54.37%, whereas the females comprised
45.62% of the population. The number of egg was 844.63+/-49.09 in 2001 and
925.35+/-49.84 in 2002.

Distribution and new host records for Cosmospora aurantiicola and Cosmospora
flammea : entomopathogens of Diaspididae in New
Zealand Plant Protection 58: 283-287. Notes:
Adventive armoured scale insects (Diaspididae) are of particular concern in New
Zealand horticulture due to their polyphagous
nature, the damage they can cause, and their implications in biosecurity. Two
important species of fungal entomopathogens recorded on armoured scale insects
in New Zealand are Cosmospora
aurantiicola(Fusarium larvarum) and C.
flammea (F. coccophilum). Both have previously been recorded in New
Zealand from unidentified Coccoidea; C.
aurantiicola has also been recorded on Hemiberlesia lataniae and
rapax. During 2002-2003, five forays were carried out to provide
further information on the host range of the species and to collect strains of
the entomopathogens that may have potential as biocontrol agents for armoured
scale insects. Aspidiotus nerii, Hemiberlesia sp., Leucaspis
brittini, Leucaspis spp., Pinnaspis dysoxyli and Eriococcus

mass-reared and used in biological control of insect pests. Experiments were
conducted to find out a better and cheaper artificial diet for mass-rearing of
adult C. carnea. Three adult diets were tested in the laboratory
conditions in comparison with standard diet; that was mixture of yeast extract,
casein, honey, sugar and distilled water. Parameters were fecundity, larval
period, pupal period and adult longevity. The results revealed that the mixture
of egg yolk, milk and honey was better than all other diets.

Scale insects are very important pests of fruit trees and they suck the sap
from the above ground plant parts thereby causing the injury. The survey work
brought to light eleven species of scale insects infesting different fruit
trees in nine districts of Himachal Pradesh, India. The
infestations of following diaspidids viz., Aonidiella aurantii was recorded on Citrus
spp. (hill lemon, rough lemon, sweet lime and sweet orange) and grapes; Aonidiella
orientalis on guava, mango and olive; Aulacaspis tubercularis,
Chrysomphalus dictyospermi, Hemiberlesia lataniae and Octaspidiotus

apple, apricot, pear, plum and sweet cherry; Pseudaulacaspis manni on
walnut; and Quadraspidiotus perniciosus [Diaspidiotus perniciosus]
(Comstock) on apple, peach, pear and plum. Out of the above mentioned
diaspidids C. asiatica is reported for the first time from India,
infesting apple and plum besides, Aulacaspis tubercularis, C. dictyospermi, H.

September 2004.] A study was carried out in an autumn-fruiting ('Autumn Bliss')
and 2 traditional ('Malling Exploit and 'Fertodi Zamatos') raspberry
plantations in Nagyrede, Hungary, between 2002 and 2003 to search for pests probably
responsible for cane death, and to study the natural enemies controlling the
population of the most important cane pests observed. In 'Autumn Bliss', all
canes were cut at the end of each vegetation period (annual growing method),
while in 'Malling Exploit' and 'Fertodi Zamatos', there were primocanes and
fructocanes every year (biennial growing method). The difference between the
growing methods and the cultivars played an important role in the incidence of
pests. In the plantations, the most frequent pest damaging canes was raspberry
cane midge (Resseliella theobaldi). The larvae of the pest were parasitized
considerably. The reared parasite was a chalcidoid species belonging to the
genus Aprostocetus. The life history of this species was also investigated.
Another important pest damaging canes was rose stem girdler (Agrilus
aurichalceus [ A. macroderus]) in the plantations, but the pest was
less dangerous in the annual growing method ('Autumn Bliss'). Further research
is needed in connection with the parasite chalcidoid species (Baryscapus
agrilorum and Tetrastichus heeringi), which were
reared from Agrilus aurichalceus larvae, for their role in the control of
the pest population. Other pests (Aulacaspis rosae, Oecanthus pellucens,
Atrococcus bejbienkoi and Lasioptera rubi) of raspberry canes
were of low significance in contributing to cane death.

Countercurrent Chromatography, CCC 2004, Tokyo, Japan, 28-31
August, 2004. Cazes, J. (Ed.)] The natural colouring agents Kaoliang (from Sorghum
nervosum [Sorghum bicolor] seed coat) and Lac (from Laccifer
lacca [Kerria lacca]) colours were separated using pH-zone-refining
countercurrent chromatography (pH-z-CCC) on an analytical or preparative scale.
The main components of Kaoliang colour have been reported to be apigeninidin
and luteolinidin, however, the structures of other compounds present in the
colour have not been elucidated as it is difficult to separate the compounds
using conventional chromatographic techniques. Therefore, the separation of
this colour was performed by pH-z-CCC that isolated three compounds. LC/MS and
SUP 1 H-NMR analyses were used to determine the structures established as a
halogenated phenyl compound, p -coumaric acid and methylated apigenin. Lac
colour mainly consists of four anthraquinone derivatives, named laccaic acid A,
B, C, and E. These four laccaic acids were separated on a large scale by
pH-z-CCC. The purified Lac colour (1 g) was submitted to pH-z-CCC with
tridodecylamine as a ligand, and produced 790, 41, 109 and 6 mg laccaic acid A,
B, C, and D, respectively, with a minimum purity of 96%.
Walter, G.H. & Abeeluck, D. 2006. Confirmation of
the existence of alloparasitoids in nature - host relationships of an
Australian Coccophagus species that parasitizes mealy bugs. Entomologia
Experimentalis et Applicata 118(2): 97-103. Notes: Heteronomous
hyperparasitoids are parasitic wasps with sex-related host relationships that
are unique to a group of genera in the chalcidoid family Aphelinidae. Females
are primary parasitoids of various sedentary bugs (mainly, scale insects, mealy
bugs, and whiteflies). Males, in contrast, are hyperparasitic, and they
frequently develop at the expense of female conspecifics. Alloparasitoids
constitute a special category of heteronomous hyperparasitoids, for their males
never develop through female conspecifics. The existence of alloparasitic host
relationships and the utility of the category 'alloparasitoid' have both been
questioned. Here, we present results that confirm the existence of the
alloparasitic way of life among heteronomous aphelinids. We investigated an
undescribed species of Coccophagus (Hymenoptera:
Aphelinidae), an Australian parasitoid that attacks the introduced lantana
mealy bug, Phenacoccus parvus Morrison (Homoptera: Pseudococcidae), in Queensland. A
year-long field survey regularly returned large numbers of female Coccophagus
spec. near gurneyi individuals from P. parvus (total n=4212), but only
few males (n=11). Males emerged from samples only when the encyrtid parasitoid Anagyrus
diversicornis (Howard) (Hymenoptera: Encyrtidae) was present in samples
in relatively high numbers. Laboratory oviposition tests confirmed that A.
diversicornis is a male host and showed that males do not develop at
the expense of conspecific females. Other studies show that males are attracted
in numbers to virgin females held in cages above mealy bug-infested Lantana
montevidensis (Spreng.) Briq. (Verbenaceae) in the field, demonstrating
that they are common in the population as a whole. This confirms that the males
need hosts other than conspecific females and that their usual hosts are
present outside of the lantana (P. parvus) system. The implications
of these results for developing a realistic classification of heteronomous host
relationships are discussed.

abundant, constituting 88.1% of the population of parasitic wasps. The
parasitism rate was 13.4%, on average. The rate of parasitism was higher on the
upper than on the lower twigs, and on the shaded portion than on the eutropic
or middle portions of Euonymus japonicus. Analysis based
on aggregation index, and Taylor's and Iwao's laws revealed that the parasitic
wasps showed an aggregated type of distribution.

with mineral, protein, fat, vitamin and glucose contents of the host plant. Wax
secretion of the male E. pela was related to the contents
of mineral, water-solubility matter, fibrin and glucose. The total amino acid
content of L. vulgare branches decreased by 28.17% due to E.
pela. The growth of the female E. pela needed K, Ca and Mn, and the

Spatial distribution of Drosicha corpulenta underground. (In
Chinese with summary in English.) Chinese Bulletin of Entomology 42(4):
412-415. Notes: The underground distribution of Drosicha corpulenta
population was investigated. The distribution and population of the insect were
correlated to distance from the base of tree trunk, mainly distributing in 0 to
5 cm soil depth from the base of tree trunk. The analysis of spatial
distribution pattern using various distribution pattern indices indicated L, m
*/ x and C were greater than 1, and C SUB A and I were greater than 0,
demonstrating that the insect had an aggregative distribution.

Fruits 1: 14. Notes: An experiment was conducted in China with
14-year-old trees of a Satsuma mandarin cultivar grafted on a rootstock of Poncirus
trifoliate. Different concentrations of 25% Arktai water dispersible
granules [of unstated composition] and 40% Supracide [methidathion] were used
for control of citrus arrowhead scale (Unaspis yanonensis). Results showed
that a 4000-6000x diluted solution of 25% Arktai water dispersible granules was
very effective at killing the scales. The best time for spraying was at the
nymphal stage. Its effectiveness could last for 25 days and was superior to 40%

Agricultural University 28(2): 152-154. Notes: The biological characteristics
of white wax scale (Ericerus pela), and the chemical control measures used on the
pest were evaluated. Mated females pass the winter on twigs and small branches
obtusifolium. In Changchun (Jilin, China),
females develop in mid-April and produce a large number of eggs from early to
late May. Eggs hatch in early June and tiny crawlers begin to move on the leaf
surface. In late August, females settle down for winter after mating with
males. The insecticides chlorpyrifos and alpha-cypermethrin were the most
effective in killing nymphs.

Vertical stratification in the spatial distribution of the beech scale insect (Ultracoelostoma
assimile) in Nothofagus tree canopies in New
Zealand. Ecological Entomology 31(2): 185-195.
Notes: The degree of infestation by New
Zealand sooty beech scale insects (Ultracoelostoma
assimile, Homoptera: Margarodidae) varies dramatically among adjacent
southern beech trees (Nothofagus spp., Fagaceae), but has
previously been assumed to be uniformly or randomly distributed within
individual host trees. In this study, a full-census survey was conducted from
ground level to canopy level on 14 naturally occurring, canopy-dominant red
beech (Nothofagus fusca) trees (size range 38.7-107.6 cm diameter at
breast height) to determine the degree of within-tree heterogeneity in
herbivore density. The within-tree distribution of the sooty beech scale was
vertically stratified and highly heterogeneous, with the greatest densities
occurring on bark surfaces in the canopy rather than on the trunk, and on the
lower rather than upper sides of the branches. The spatial distribution was
strongly negatively correlated with trunk and branch diameter, and increasing
bark thickness (as a function of diameter) provides a plausible explanation for
differences in the establishment and population density of sooty beech scale
insects with trunk and branch size. Furthermore, there was a significant change
in the spatial distribution of scale insect populations on trunks and branches
of trees of increasing diameter at breast height. This indicates a strong
temporal component to the spatial dynamics of the sooty beech scale insect
driven by changing host phenology. Future studies on phytophagous insects
infesting large host trees need to consider more explicitly changes in
population dynamics through space and time. Because of the high degree of
within-tree heterogeneity in population density, the total population size of
scale insects on an individual tree could not be predicted from any measure of
population density low on the trunk. However, the dry weight biomass of sooty
mould fungi growing on the ground beneath infested trees was a remarkably
accurate predictor of the total population.

Density-dependent effects on the reproductive fitness of the New
Zealand beech scale insect (Ultracoelostoma assimile)
across multiple spatial scales. Ecological Entomology 30(6): 733-738. Notes:
Intraspecific competition can be an important factor influencing the individual
fitness of organisms. This study reports density-dependent effects on the
fecundity of the beech scale insect (Ultracoelostoma assimile, Hemiptera:
Margarodidae) on naturally occurring, canopy-dominant red beech (Nothofagus
fusca, Fagaceae) trees in New
Zealand. For the first time an increasing
intensity of intraspecific competition at increasing spatial scales within individual
host trees is demonstrated. Beech scale insect 'tests' containing adult female
scale insects and eggs were collected from the trunks of 10 red beech trees
[17.7-48.5 cm in diameter at breast height (1.4 m), d.b.h.] with varying
densities of scale insect infestation. The relationship between individual
female fecundity and scale insect density at three spatial scales: local
(within 5 cm), lower trunk (below 2 m above ground level), and whole tree, was
tested. Beech scale insect fecundity was density dependent, with total female
egg load decreasing with increasing scale insect density. The strength of the
density-dependent effect increased with increasing spatial scale, suggesting
that scale insects are creating a tree-wide drain on the quality of phloem sap,
rather than depleting nutrients from localized, high-density areas within
trees. These results indicate that at high densities, the New Zealand beech
scale insect can have a negative effect on the nutritional quality of the
phloem of red beech, thus negatively affecting conspecifics elsewhere on
individual host trees. The increasing intensity of the effect with increasing
spatial scale within individual trees emphasizes the importance of measuring
density-dependent effects at the appropriate spatial scale.

Preliminary evidence suggests that beech scale insect honeydew has a negative
effect on terrestrial litter decomposition rates in Nothofagus forests of New
Zealand. New Zealand Journal of Ecology 30(2): 279-284. Notes: Honeydew
production by New Zealand beech scale insects (Ultracoelostoma spp.,
Hemiptera: Margarodidae) is widely considered to have a positive influence on
native animal abundance and ecosystem functioning. As a first assessment of
whether there is a positive relationship between honeydew throughfall and
litter decomposition rates, we placed experimental litter bags in each of 10
high and 10 low honeydew plots in mixed southern beech (Nothofagus) forest at
each of two sites, Lakehead and Rotoiti, in the Nelson Lakes National Park.
High and low honeydew plots were selected using sooty mould biomass on the
forest floor as a surrogate for honeydew through fall, as sooty mould biomass
was shown to be strongly correlated (r = 0.906) with scale insect population
size at the Rotoiti site. Contrary to our expectation, terrestrial litter
decomposition was significantly lower in high honeydew plots than in low
honeydew plots, at both Lakehead and Rotoiti. The presence of introduced wasps
spp., Hymenoptera: Vespidae) at the Lakehead site did not appear to have any
significant effect on litter decomposition rates, despite the fact that wasps
are thought to intercept much of the honeydew produced in this forest. Variance
in litter decomposition rates between high and low honeydew treatments was
predominantly determined by a direct relationship between sooty mould biomass
and litter decomposition rate at the scale of individual litter bags. However,
the mechanistic explanation for the observed relationship is unclear. Future
studies should be directed towards quantifying the functional relationship
between honeydew through fall and growth rates of sooty mould, and their
subsequent effects on abiotic conditions, microarthropod community dynamics and
microbial activity rates in litter.

Structural and compositional change in an old-growth eastern hemlock Tsuga
canadensis forest, 1965-2004. Forest Ecology and Management 231(1/3):
114-118. Notes: Eastern hemlock (Tsuga canadensis) was once
relatively common in the northeastern USA. However, recent disturbances -
including exotic pests (Adelges tsugae and Fiorinia
externa) and white-tailed deer (Odocoileus virginianus)
overpopulation - have exacerbated declines in eastern hemlock forest in the
20th century. As a previously undisturbed stand, the Mianus River Gorge
Preserve (MRGP) in New York provided an ideal site to investigate the potential
impact of these factors on the structure and composition of old-growth eastern
hemlock forests. The woody vegetation of this forest was first surveyed in 1965
and then again in 2004. The overstorey tree community was similar between the
two time periods with eastern hemlock dominant in both samples. Conversely,
seedlings, saplings, and transgressives exhibited sharp declines in most
species, including eastern hemlock, which resulted in dissimilar community
composition and structure for these age classes between 1965 and 2004. Despite
relative continuity in the dominance of mature eastern hemlocks, low
recruitment due to overbrowsing makes the long-term persistence of eastern
hemlock in the old-growth forest of MRGP tenuous.

Wiesenborn, W. D. 2005. Biomass of arthropod trophic levels
ramosissima (Tamaricaceae) branches. Environmental Entomology 34(3):
656-663. Notes: Tamarix ramosissima Ledebour (Tamaricaceae) is an invasive
shrubby tree naturalized in riparian areas throughout the western United
States. Biomasses of arthropod taxa on T. ramosissima branches were
quantified as dry mass per plant dry mass on three trees at each of three sites
near surface water at Las Vegas Wash, NV, during 2002 and 2003. Biomass of two
phytophagous-arthropod taxa, Opsius stactogalus Fieber
(Homoptera: Cicadellidae) and Chionaspis spp. (Homoptera:
Diaspididae), comprised 97.7% of arthropod biomass and varied among sites and
among trees within sites. Their biomass was positively related to percent water
of branches. Biomass of O. stactogalus was strongly
associated with those of its parasites, Polynema saga (Girault) (Hymenoptera:
Mymaridae) and Gonatopus sp. (Hymenoptera: Dryinidae), and predatory
Dictynidae (Araneae) and weakly associated with those of omnivorous Attalus
spp. (Coleoptera: Melyridae) and Formica xerophila M. Smith
(Hymenoptera: Formicidae). Biomass of Chionaspis spp. was only associated
with biomass of predatory Cybocephalus californicus Horn
(Coleoptera: Nitidulidae). Biomass of predatory Salticidae (Araneae) was not
associated with that of either phytophagous arthropod taxon. Low percentage of
secondary-consumer biomass and large fluctuations in biomasses of O.
stactogalus and Chionaspis spp. between years
suggest populations of phytophagous arthropods on T. ramosissima are not
regulated by natural enemies. T. ramosissima branches offer
vertebrates arthropod prey with low diversity and highly variable biomass.

Washington; Delemont, Switzerland: Island Press; CABI Bioscience Centre.Notes: Prevention is the first and most
cost-effective defense against invasive alien species. The use of species lists
in prevention is discussed, and three further principal strategies to reduce
introductions (interception, treatment and trade prohibition) are outlined. The
value of early detection and the need for contingency plans are covered. Even
the most effective prevention and early warning systems have leaks, so control
options must be investigated; the factors that a management project dealing
with invasive species must address are given. Best practices in eradication,
containment and control (including mechanical, chemical and biological control,
habitat management and integrated pest management) are outlined. The following
examples are given: the Australian Defense Force s efforts to prevent the
introduction of species from East Timor by returning troops, public awareness
and early detection of Miconia calvescens in French
Polynesia, eradicating screwworms (Cochliomyia hominivorax) from North
America and North Africa and biological control of the orthezia scale (Orthezia
insignis) on St. Helena to save the endemic tree, Commidendrum robustum.

and chemical composition of waxes secreted by two wax scale insects, Ceroplastes
ceriferus (Fabricius) and C. japonicus Green (Homoptera:
Coccidae).]. (In Chinese.) Acta Entomologica Sinica 48(6): 837-848. Notes: The
ultra-morphology and chemical composition of waxes secreted by the scale
insects, Ceroplastes ceriferus (Fabricius) and C. japonicus Green
(Homoptera: Coccidae) were studied with the techniques of scanning electron
microscope (SEM) and gas chromatography/ mass spectrometry (GC/MS). The results
indicate that the two wax scale insects have a similar waxy secretion and wax
test forming process. The scale insects in their first and second instars
secreted dry wax that formed a star-shaped test. Every wax horn around the
margin of the test consists of two segments. This corresponds to the two
developmental instars. Furthermore, each of the two segments of the wax horn
included many sub-segments. Meanwhile, wax accumulated into a cap-like
structure with many layers on the dorsal region of the body. It was believed
that some kind of rhythm existed in the secretion of wax. A lot of striate
punctures formed wax glands that are not usually found with on slide specimens
of wax scale insects observed under light microscopy. As the scales developed
into the 3rd instar and adult stage, the wax secretion changed into "wet
state" and formed a waxy test in tortoise shell shape. The wax glands on
the dorsal surface mainly are trilocular and quadrilocular pores. Dense wax
pores arranged in longitudinal strips were also found on the anal plates. The
main chemical compositions of the wax secretions of the two scale insects were
determined with GC/MS by the esterification and unesterification. For C.
ceriferus, 14 and 14 compounds were determined from its wax secretion
with the two methods respectively; while 10 and 25 compounds were determined
respectively from the wax secretion of C. japonicus. The main compositions
of the wax secretions include a series of long chain saturated and unsaturated
hydrocarbons, fatty acids, fatty alcohol, esters, and some compounds with ring
structures of multi-, macro-, or heterocyclic ring. Their biological functions

ultra-morphology and chemical composition of waxes secreted by the scale insect
shanxiensis (Homoptera: Coccidae) was researched with the techniques of
scanning electron microscope (SEM), infrared absorption spectra (IR) and gas
chromatography/mass spectrometry (GC/MS). The result indicated that the scale
insect secreted wet wax in its nymph stage. The wet wax coagulated into
translucent wax covering on the body surface. However, the female adult
secreted its wax secretion with white color and long thread form. According to
the infrared absorption spectra characteristic of the waxes, it can be known
that both waxes either from male nymph or female adult were composed by a
series of saturated and unsaturated long carbon chain compounds. But the two
waxes are different in the chemical functional group's kind and numbers that
composed the compounds, because of the differences in absorption peaks' numbers
and forms which appeared in the two infrared spectra from the wave number 1 800
cm-1 to 1 000 cm-1. Through detected with GC/MS, 14 compounds with carbon atom
number form C13 to C32 were obtained form the wax of the male scale insect.
These compounds included 5 saturated higher fatty acids, 1 unsaturated higher
fatty acid, 1 saturated higher fatty alcohol, 1 unsaturated higher fatty
alcohol, 1 unsaturated ester, 1 saturated aldehyde. and 4 saturated alkane

presents one new species of the genus Coccidencyrtus Ashmead, i.e. Coccidencyrtus
longiclavatus Xu sp. nov. collected from Shangdong, Jiangsu, Zhejiang,
Fujian in China. A key for three species of Coccidencyrtus Ashmead
from China is given. One new species of the genus Mayrencyrtus Hincks are
presented in this paper, i.e. Mayrencyrtus longiscapus Xu sp. nov.
collected from Shanxi, Shaanxi in China. All specimens are deposited in the
Institute of Applied Entomology, College of Agriculture & Biotechnology,
Zhejiang University. Coccidencyrtus longiclavatus Xu, sp.
nov. Host: Quadraspidiotus pernisiosus on pear tree, Lopholeucaspis japonica
on Citrus, Diaspids on walnut tree. Distribution: Shangdong (Tai'an) , Jiangsu
(Donghai), Zhejiang (Linhai), Fujian (Jianning). This species is similar to Coccidencyrtus
exiguous Noyes et Ren, and Coccidencyrtus mandibularis Hayat,
Alam et Agarwal 1975, but can be distinguished from the latter by 1) antennal
scape 4.6 times as long as wide, 2) the first-fifth funicle segments subquadrate,
3) clava as long as funicle and half pedicel combined, with truncated apex. Mayrencyrtus
longiscapus Xu sp. nov. Host: Eulecanium gigantea, Drosicha
contrahens. Distribution: Shanxi (Taiyuan), Shaanxi (Yangling). This
species is similar to Mayrencyrtus japonicus Tachikawa.

[A study on afforestation and utilization of kusum as a lac host.]. (In Chinese
with summary in English.) Forest Research 18(2): 204-208. Notes: A study was
conducted on the sowing technology, afforestation, branch utilization and
biological characteristics of Schleichera oleosa as lac (Kerria
lacca) host. The results showed that seed germination rate could be
increased by removing the capsule. Seedlings were raised in March and planted
at the beginning of monsoon (June and the first 10 days of July) in Yunnan
Province, China. The land suitable for the tree should be deep and loose soil,
and good drainage condition such as in the mid- and low area of hillside.
Afforestation effect could be better if the tree was planted at the south side
of the hill. Young sapling could grow better with scarification, weeding and
fertilizer application. S. oleosa was the best host tree for
lacca and the output of lac was stable during winter and summer. It was
also a favourable tree species for keeping brood and producing lac.

[Occurrence and infestation of pest insects on apricot in Xinjiang, China.].
(In Chinese with summary in English.) Xinjiang Agricultural Sciences 42(5):
363-365. Notes: Approximately 57 species of insect pests infest apricots in
Xinjiang, China, among which 19 are serious ones. Brachycaudus helichrysi,
Hyalopterus amygdali, Eutetranychus pruni, Bryobia rubrioculus, Apocheima
cinerarium, Orthosia incerta, Malacosoma parallela and Euproctis
kargalika mainly attack the leaves. Rhynchites auratus, Laspeyresia
pomonella [Cydia pomonella], Grapholita molesta and Eurytoma
samsonowi mainly attack the flower, fruit and seed. Sphaerolecanium
prunastri, Parthenolecanium corni, Pseudaulacaspis pentagona, Quadraspidiotus
perniciosus [Diaspidiotus perniciosus], Scolytus seulensis, Scolytus rugulosus
lineatella mainly attack the branches and stems.

Change in volatiles of Diospyros kaki L. f. damaged by Ceroplastes
japonicus Green and their attraction to Chilocorus kuwanae
Silvestri. (In Chinese with summary in English.) Chinese Journal of Applied and
Environmental Biology 12(2) Serial No. 60: 215-219. Notes: Diospyros kaki L. f.
(Ebenaceae), which could release volatiles to attract a natural enemy ladybug
after damaged by Ceroplastes japonicus Green (Homoptera: Coccidae), was studied
in this paper. The result showed that 74.17% damaged twigs and leaves were
found attracting Chilocorus kuwanae, and the undamaged ones were only 20.00%.
The volatiles of D. kaki could be greatly changed and had a higher attractive
ability to C. kuwanae when the host plant was damaged by C.
japonicus. The compounds and relative contents of two volatiles were
analyzed by gas chromatography/mass spectrum (GC/MS). The volatiles from
undamaged twigs and leaves were found with 29 kinds of compounds and 92.98%
relative contents of hydrocarbons, and those from damaged ones with 32 kinds
and 97.15%. Furthermore, 3 kinds of alcohol and 2 of hydrocarbon disappeared
from the volatiles, and 8 new compounds were found, including 4 kinds of
hydrocarbon, 3 of terpene and 1 of ketone. These new compounds possibly
possessed biological function in attracting C. kuwanae. D.
kaki was shown to release infochemicals to attract natural enemies
after it was damaged. The result could be used in ensuring infochemicals,
simulating attractant and exploring new approach in biological control.

Effect of the pest Marchalina hellenica Gennadius (Homoptera, Margarodidae) on the
growth parameters of Pinus brutia Ten. in Mugla Region
(Turkey). Polish Journal of Ecology 53(3): 451-458. Notes: Marchalina hellenica
Gennadius is a common pest prevalent in Pinus brutia Ten. forests in Mugla
province of Mediterranean Region of Turkey (28 degrees 20'03"E; 37 degrees
12'18"N). The pest is known to suck sap from a number of pine tree
species, especially Pinus brutia. The goal of this research is to determine whether
the pest has a negative impact on the volume increments of Pinus brutia trees and
forests. Two areas with identical site conditions are selected for study: one
non-infested and one infested with Marchalina hellenica. The effects of
site quality and age on the sampled trees have been eliminated. The diameter
growth at breast height, basal area (the cross-sectional area of a tree at
breast height) and the increment of tree volume are determined separately for
both study areas. A t-test applied to volume increments of both infested and
noninfested trees of all ages proves that infestation causes significant
negative impacts on trees between the ages of 40 and 80 years. The greatest
loss of increment in single trees is 2.0% (of the volume of non-infested tree)
which occurs at the age of 70 years old. When considering the entire stand, the
greatest loss of increment is 3.4% (of the volume of non-infested stand) which
occurs at the age of approximately 45 years.

conducted to test the quality of the parasitoid Aphytis melinus DeBach
(Hymenoptera: Aphelinidae), the main bio-control agent of the California Red
Scale Aonidiella aurantii Maskell (Homoptera: Diaspididae), reared in
the insectary of the Sicilian Regional Phytosanitary Service. The trials were
conducted following the guidelines of the IOBC working group "Quality
control of mass reared arthropods", under the following conditions
25+/-2(deg)C, 60+/-10% RH, 16L:18D. The parameters analyzed were the number of
adults as specified on the releasing container, the sex-ratio (100 adults from
bulk material), survival in transport (1000 adults maintained at 17+/-2(deg)C
for 5 days in a container with honey on the lid) and fecundity (observed on 30
females placed individually in contact for 5 days with 100 specimens of Aspidiotus
nerii Bouche (Homoptera: Diaspididae) on squash). The data on the
number of adults confirmed the quantities indicated on the containers and
averaged 5000+/-500 (n=3). The percentage of females was 70.8+/-4.6% (n=5) and
the percentage of mortality after 5 days was 9.3 (n=5). The mean progeny
produced per single female was 39.67+/-10.63% (n=3).
