ISSIS-XI
Manuela Branco, Instituto
Superior Agronomia, Universidade Técnica de Lisboa (ISA-INIA), Portugal: The meeting will be held on the
campus of the National Agronomic Station (Estação Agronómica Nacional, Instituto Nacional de
Investigação Agrária (EAN-INIA)). It will be jointly organized and sponsored by
ISA-UTL and EAN-INIA. The meeting place
is located in a park in the city of Oeiras,
which is about halfway between Lisbon
(17 km distance) and Cascais (13 km).
Travel to both cities can be made by train, more or less in 15 min.
Oeiras is near an interesting tourist region in the route line Lisbon- Estoril
- Cascais - Cabo da Roca (the westernmost point in Continental Europe) and
Sintra (UNESCO World Heritage Centre), which we will explore for the one-day
field trip including the possibility of collecting scale insects (e.g., in
Sintra). The date of the meeting is not
decided, but we are planning for it to be between the end of September 2007
(two last weeks) and early October (first week). We are planning to send the first
announcement out sometime during the first three months of 2006. If you need more information or details
please do not hesitate to contact me (mrbranco@isa.utl.pt).

Lerzan Erkilic, Plant Protection Research
Institute, Adana, Turkey: I
hope that everyone received their copy of the proceedings. If not, they can
find them at the following address: http://www.yyu.edu.tr/issis.asp The site also includes images of activities
during the meetings. I would like to
thank Bora for all his efforts in preparing the proceedings and putting them at
this address at Yüzüncü Yil
University. I hope the coming year brings health,
happiness and success to all.

Michelle Leddel,
Century High School, Alhambra, California, USA and Joel Grossman, editor of IPM
Practioner, California, USA: 'Our little scale insect' may become a household term after
people learn about a just published book, "A Perfect Red." By Amy
Butler Greenfield. Joel Grossman, who writes the Entomological
Society of America Conference Highlights for the IPM Practitioner, and I have a
book review that should be of broad interest to readers of the Scale. For more information see www.amybutlergreenfield.com and www.aperfectred.com.
REVIEW OF NEW BOOK "A Perfect Red: Empire, Espionage,
and the Quest for the Color of Desire" (Harper-Collins, 2005; 338 pages;
ISBN: 0060522755). This is a tale of
colonialism, empires, world trade, pirates, fashion, the color red, and a scale
insect, Dactylopius, whose harvest as
a medicine, clothing dye, food ingredient (mixed with chocolate it looked like
a bowl of blood and repulsed the Spanish Conquistadors), etc., dates back
thousands of years in the Americas. The book, which includes tales of botanical
and scale insect espionage, is designed to appeal to the general reader. It
reads like a novel, because its author Amy Butler Greenfield has the skills of
a novelist. Greenfield is also an
historian with knowledge of multiple languages, which aided in combing European
archives for documents pertaining to world trade in the red cochineal dye
harvested in the bodies of Dactylopius
scale insects grown in southern Mexico.
A Perfect Red places the cochineal scale into the larger fabric of world
history. That history is surprisingly relevant today, with its geo-political
intrigue and stories of heads of state (e.g. Spanish kings) turning to deficit
spending and going beyond their budgets to finance their imperial aims,
religious agendas, and military machines. Indeed, the cochineal scale insect
grown by small farmers in southern Mexico
was second only to silver in providing the financing that kept the Catholic
Spanish Empire on top of the world and ahead of the Protestant British in the
16th and 17th centuries. Far from being a textbook, this book places scale
insects into the heart of modern world history and is very enjoyable reading.
It will be a welcome change of pace from scientific papers, and provide readers
with some cochineal scale historical tales to enliven dinner and party
conversations. Some of the gaps in our
knowledge are almost as interesting as Greenfield's
sweeping world history, and it is here that entomology using modern DNA and
other technologies can be brought into play. For example, it is clear that the
cochineal scale insect of commerce was deliberately bred for its red dye in
southern Mexico.
But not even Greenfield can tell us
how many thousands of years ago the Dactylopius
of commerce was first cultivated by the ancient Mexicans. Just as we unravel the genetic heritage of
corn, we might similarly determine when the cochineal scale (and perhaps also
its prickly pear cactus host plant) was first domesticated. Indeed, being able
to date scale insect domestication in Mexico
and comparing it to silk moth domestication in China
would be useful to historians, anthropologists, and others.
Lerzan Erkilic, Plant Protection Research Institute, Adana, Turkey: Since
2004, I am spending more research effort on the practical side of scale insects
studies. We recently established a beneficial insects rearing facilities for
citrus mealybug biological control in citrus groves rearing Cryptolaemus montrozieri and Leptomastix dactylopii. We also provide
advice and technical services to facilitate the usage of beneficials in citrus
groves. However, biological control is currently used in only about 5% of
citrus due primarily to problems with pesticide residues.
Jan Giliomee,
University of Stellenbosch, South Africa:
During the past year my post-doc student Waktola Wakgari and I published
descriptions of all female stages of six mealybug species that occur on citrus
in South Africa (African Entomology 13:281-332). This was necessary to enable
the morphological identification of immatures (and adults) that may be found on
exported fruit. The presence of South African endemics on fruit is of course
not acceptable to importing countries and may lead to consignments being
destroyed. Waktola briefly returned to South
Africa from Ethiopia,
where he now works, to bring about changes to the manuscript suggested by our
valued reviewer Penny Gullan, who happened to be visiting from California
at the time.
Giuseppina Pellizzari, Universita di Padova, Legnaro,
Italy: I am
continuing my work on collecting Italian scale insects. Among them several
appear to be new species, but I have not had time to describe them. I hope to
begin doing this in the near future. Last year we discovered two new alien
scale species that are recorded outdoors in Italy
for the first time, namely Fiorinia pinicola and Pseudococcus
comstocki. A third species, an Eriococcus species, was recorded on
ornamental plants of Leptospermum scoparium, a plant native to New
Zealand. Rosa Henderson kindly provided me
with descriptions of New Zealand
eriococcids and I also checked the Australian species but my specimens don’t
fit any of them. Has anyone else collect
eriococcids on Leptospermum? Dug Miller thinks the Eriococcus species may be native to North America. During 2005, I collaborated with two Italian
colleagues (Tino Russo and Antonio Tranfaglia) in writing a book on the scale
insects of olive and fruit trees; it is near completion and will be in press
soon. In addition, I am working with several European colleagues to build a
list of alien arthropod species of Europe. It consists of compiling a list of alien
arthropod species (except Aranea and Crustacea) in Europe.
Alien species are defined as species whose primary introduction was caused
directly or indirectly by man’s activity. We will use 1492 (or the
"discovery" of America)
as the departure date for considering species aliens. We will publish the
results in a book "Alien invasive species of insects and mites in Europe". In the list of alien introduced insects, as
you can imagine, scales constitute a major component.
Yair Ben-Dov, Department of
Entomology, Agricultural Research Organization, Bet Dagan, Israel: During 2004 I have been updating the 11 families, which I
am processing, for ScaleNet, the
joint project with Dug Miller. Data were added and updated on the families: Aclerdidae, Asterolecaniidae, Beesoniidae,
Carayonemidae, Coccidae, Dactylopiidae, Diaspididae (subfamilies Aspidiotinae,
Comstockiellinae and Odonaspidinae), Kerriidae, Lecanodiaspididae, Margarodidae
and Pseudococcidae. This is the appropriate time to thank our colleagues
for the comments, notes and corrections which they sent us. We very much
appreciate your feedback, as it contributes to ScaleNet, for the benefit of
all. The Catalogue of the Margarodidae (Ben-Dov, Y. 2005. A systematic
catalogue of the of the Scale Insect family Margarodidae (Hemiptera: Coccoidea)
of the world. Intercept
Publishers, Wimborne, UK & Lavoisier, Paris. 400 pp.) was
published on January 2005, and it is available for purchase from the Publisher;
information is available at the URL: http://www.intercept.co.uk. Subsequently, the database for the family has been added to
ScaleNet, and it is now available on-line.
The website Directory of
Scale Insects (Hemiptera: Coccoidea) Systematists, was developed and
placed on-line during 2004 on the Internet at the URL: http://www.agri.gov.il/publications/systematists. This website was developed to provide
information on systematists of scale insects, beginning with Carl von Linnaeus
(1707-1778) to the present. A scale
insect systematist is regarded, in the context of this Directory, as a person
who has been either an author or co-author of a new taxon in the Coccoidea.
During 2005 I have added data for several ‘new’ systematists, corrected errors
and supplemented the information from available records. It is my wish to
update and upgrade the Directory. Therefore, 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 to the included information, please send the information by email
to yairbd@int.gov.il.
Chris Hodgson, The National Museum of Wales, Wales, UK: All of the projects listed
in last year’s “The Scale” as being nearly completed are finished and are
either in the late stages of publication or have been published. In addition, Jon Martin and I published a
paper on a new soft scale genus (Fistulicoccus)
and 2 new species from Hong Kong and New
Guinea (in Zootaxa). The following projects are now at an advanced
stage and should be published reasonably soon: Vahedi & Hodgson - on some Porphyrophora species from Europe, the
Middle East and north Africa (in Systematics and Biodiversity); Hodgson &
Foldi - morphology of the adult males of Margarodidae sensu Morrison (in
Zootaxa); the morphology of Marchalina
hellenica (with Sofia Gounari); a revision of the soft scale genus Cissococcus in South Africa (with Ian
Millar - we believe this genus does belong to the Coccidae but it is the only
known gall-forming soft scale); a check list of the insects of the Galapagos
Islands (with Charlotte Causton and many others); the systematics and biology
of the South African eriococcid genus Calycicoccus
(with Penny Gullan, Jan Giliomee and Lyn Cook).
On-going projects are: the phylogeny of the non-margarodoid genera based
on adult males; a revision of the monophlebid genus Palaeococcus (with the help of Zvi Mendel, Sofia Gounari and
others); a possible revision of the margarodid genus Stigmacoccus (with Gillian Watson and Amauri Bogo); descriptions of
the type species of the South American eriococcid genera (with Dug Miller); the
immature stages of New Zealand Coccidae (with Rosa Henderson); the males of the
diaspid genus Leucaspis from New
Zealand (with Rosa Henderson and Ben Normark); and, finally, a revision of the
Coccidae of Australia (with Penny Gullan).
None of this would be possible without the on-going support of the
National Museum of Wales, Cardiff,
to whom I am extremely grateful.
Penny Gullan, Rhodes University, Grahamstown, South Africa: I'm writing this from Doug Downie's lab at Rhodes
University in Grahamstown. Pete
Cranston and I have been on sabbatical leave in South
Africa since the end of September and are
enjoying the change of scene, as well as the escape from administration and
teaching. While here I'm mainly working on the taxonomy of mealybugs of the
South African endemic plant genus Elytropappus
(Asteraceae). The best known and most widely distributed species of Elytropappus, E. rhinocerotis, commonly is called "renosterbos"
(rhinoceros bush) because early settlers believed that it was eaten by
rhinoceros. Apparently there's no evidence for that claim. Certainly it is not
palatable to livestock, but is a weedy pasture shrub in many places. However,
both gall midges (Cecidomyiidae) and mealybugs seem to like it, and a few
species of each induce galls on the foliage. In addition to gall-inducing
pseudococcids, especially of the genus Diversicrus,
there are other mealybug species that live among the bracts of galls induced on
renosterbos by the gall midges and yet other mealybugs that feed on the stems.
So the insect-plant associations are complex.
In mid October, Pete and I spent an enjoyable few days in Stellenbosch,
where we were looked after royally by Jan and Warnia Giliomee. We gave seminars
at Stellenbosch University,
met with other other academics and friends, and did some collecting and
sightseeing in the local area. Jan has kindly agreed to continue the search for
Diversicrus mealybugs on Elytropappus, since the type locality
for the type species, D. longulum, is
fairly close to Stellenbosch. I'm
looking forward to a visit to the South African National Collection of Insects
(SANC) in December. I'll spend a week there hosted by Ian Millar and get the
chance to examine their extensive collection of African scale insects,
including type material from De Lotto and Brain. One taxon of special interest
to me, Ian and Chris Hodgson is Cissococcus
Brain, which is gall-inducing on Rhoicissus
(Vitaceae). Cissococcus is believed
to be the only member of the family Coccidae to induce complex (covering) galls,
but I had been guessing that it's really an eriococcid, perhaps related to the
only native South African eriococcid, Calycicoccus
(also a gall inducer). Chris Hodgson has studied immature and adult males of a
couple of collections of Cissococcus and
he's still betting on Coccidae. I now have some fresh specimens and the nymphs
sure do look coccid-like. Hopefully the DNA will tell us the true
relationships. While I'm enjoying
southern Africa, my lab group at University
of California, Davis (UCD), is busy
with taxonomic and molecular activities on various scale insect groups. Cory
Unruh is continuing her taxonomic and molecular phylogenetic research on
iceryine margarodids for her Ph.D. Nate Hardy is completing the required
coursework as well as doing molecular work for his Ph.D. on Australian
gall-inducing eriococcids. Janie Booth is finishing up her Masters on Matsucoccus. Demian Kondo has become a
gel-jock! Under the expert tuition of originally Lyn Cook and now Geoff Morse,
he has been extracting DNA, doing PCRs and getting nucleotide sequences for
coccids. He plans to produce the first molecular phylogeny for the higher
groups within Coccidae and perhaps challenge (or support) the Hodgson higher
classification of the family. In June
2005, our PEET (Partnerships for Enhancing Expertise in Taxonomy) team had
another get-together at UCD. Thirteen of us participated for part or all of a
week: the Normark lab (University of Massachusetts, Amherst), the Gullan lab
(UCD), Ray Gill and Gillian Watson (California Department of Food &
Agriculture, Sacramento), Dug Miller (USDA, Beltsville) and Lyn Cook (all the
way from the Australian National University, Canberra). We ran a workshop on
cytology and endosymbionts of scale insects, at which Lyn was the lead trainer,
showing us the wonders of coccoid chromosomes. Lyn also went on a pre-workshop
field trip with Ben Normark and his students, and she stayed on in Davis
after the workshop to work on a long overdue Gullan & Cook manuscript
(which is still not done). I'll be seeing Lyn briefly in January 2006 when I
travel back to California via a
two-week stop in Australia.
I will also see Rosa Henderson at Landcare Research,
New Zealand, for one day
in February.
Imre Foldi, Muséum
national d'Histoire naturelle, Paris, France: My research on the archaeococcoids
has resulted in two publications in 2005. One on the Matsucoccidae of the
Mediterranean basin, the other on a generic revision of the family Margarodidae
sensu stricto. I also have a paper in
preparation on a generic revision of the family Monophlebidae, with
descriptions of several new species. In
addition, Chris Hodgson and I are collaborating on a very interesting
comparative study on margarodid males; this is finished and is in press. We intend to follow this with another, more
complete phylogenetic analysis based on adult males. With Ferenc Kozàr, I am
currently working on some mealybugs from South America
collected on one of my collecting trips.
I have enjoyed working with both Chris and Ferenc. It was also a great pleasure to meet with
Douglas Williams again in 2005 and have discussions during his recent visit to Paris.
André
Panis, Laboratoire de Biologie des Invertebres, Antibes, France:
I made short collecting trips to northern or higher altitude localities
in the southern sections of France
where some cold-limited scale-insect species were collected in the wild many
years ago. I was investigating the question of their survival in the hard
winter of 2005. A paper is in
preparation on the present distribution and new host-plants of one of these
species, Icerya purchasi Maskell,
about one century after its introduction (on the French Riviera in 1910). Yearly number of generations of Pseudococcus maritimus (Ehrhorn) was
established in a vineyard. I found P.
maritimus, as morphologically defined by Gimpel and Miller (1996), on wine
grapes in the southern areas of France
in the seventies for the first time and again in 1999 and 2000. Three mealybugs
are widely distributed in the southern vineyards: Heliococcus bohemicus Sulc, Phenacoccus
aceris (Signoret), and Planococcus
ficus (Signoret). Two other species are restricted to just a few vineyards:
Planococcus citri (Risso) and Pseudococcus maritimus. In some areas Pseudococcus viburni (Signoret), which
is very similar to P. maritimus,
lives on wine grapes. I have not found it on wine grapes in the south.
Laurence Mound, Australian National Insect Collection, Canberra, Australia:
We have recently completed an inventory of the Pseudococcidae slide
material in the collection and are planning to do the rest of the Coccoidea
slide collection in the near future.
This inventory is included in this edition of “The Scale” on page 13.
Also since many of the readers of “The Scale” may be interested in
aphids, I want to draw attention to the ABRS list of Australian aphids.
See www.deh.gov.au/cgi-bin/abrs/fauna/tree.pl?pstrVol=APHIDOIDEA&p
Wengei Tong, Harvard University, Cambridge, Massachusetts USA: I'm just starting my PhD at Harvard,
and am thinking of working on Icerya
purchasi and East African scales. Ben Normark suggested that I post a note
about this on "The Scale".
Adrian
Rakimov, Mildura, Australia, : I have recently been
introduced to the fantastic world of scale insects. I am one year into my PhD
on the distribution, lifecycle and biological control of the grapevine scale (Parthenolecanium
persicae) in Australian vineyards. Very little work has been done on P.
persicae and other coccids in Australian vineyards, which has made my work
challenging, but at the same time provided me with a wealth of opportunities! Parthenolecanium
persicae is the most common coccid pest of grapevines in Australia, however, I have also found significant infestations of Coccus
hesperidum and Parasaissetia nigra. To date I have collected a
number of parasitoids of P. persicae from around Australia including; Coccophagus lycimnia, Metaphycus
maculipennis, M. helvolus, Microterys sp. and Cheiloneurus
sp. I have also collected male P. persicae and this appears to be the
first record of them in Australia. Currently, I am establishing glasshouse cultures of P.
persicae and parasitoids to be used in future bioassay experiments. I also
plan to look at how ants affect the ability of natural enemies to control
populations of P. persicae. If anyone has any obscure or hard to get P.
persicae papers or specimens, it would be greatly appreciated if you could
send them to me at: The Department of Primary Industries, PO Box 905,
Mildura, Victoria 3502, Australia.
Selma Ulgenturk, Ankara University Agriculture Faculty, Ankara
– Turkey: This year I continued my research in
the following areas: 1) Biological
control of euonymus scale (Unaspis
euonymi Comst., Diaspididae) using Chilocorus
kuwanae Silvestri (Coccinellidae); 2) Biological relationships between some
mealybugs and the parasitoid Anagyrus
pseudococci (Girault) (Encyrtidae) and their interactions with the mealybug
predator Cryptolaemus montrizieri
Mulsant (Coccinellidae); 3) The effectiveness of entomopathogen Paecilomyces farinosus (Deuteromycotina:
Hyphomucetes) on citrus mealybugs Planococcus
citri (Risso) and P. ficus (Signoret)
(Pseudococcidae) and the interactions of the mealybugs with fungicides. I also completed the following research: 1)
Studies on some biological characters of Planococcus
citri (Risso) on certain ornamental plants under laboratory conditions. 2)
Some morphological and biological characteristics of Melanaspis inopinata Leonardi (Diaspididae)
Demian Kondo, University of California, Davis California, USA: The year 2005 has been flying by pretty fast for me; too
many projects and too little time. My work this year can be summarized as
follows: I had finally described a new mango pest coccid from Thailand in
collaboration with M.L. Williams (Zootaxa: 1045:25-37); with P.J. Gullan we
published a review of the genus Austrotachardiella Chamberlin and described
a new species from Colombia (Neotropical Entomology 34(3): 395-401); with M.L.
Williams and P.J. Gullan we erected the new genus Octolecanium in order
to accommodate Neolecanium perconvexum (Cockerell) and describe a new
species from Guatemala (TIP Revista Especializada en Ciencias
Químico-Biológicas 8(1): 5-11); also with Mike and Penny, we reviewed the
coccid genus Xenolecanium Takahashi and erected the new genus Takahashilecanium
in order to accommodate Xenolecanium perconvexum Takahashi (Entomological
Science 8: 109-120); a short paper and abstract with Mike on the coccid genus Akermes
Cockerell came out in the ISSIS proceedings (Proceedings of the X international
symposium of scale insect studies; Pp. 71-77; P. 78, April 19-23, 2004, Adana,
Turkey). Two more papers are in press, the first one on the taxonomy and
biology of the mealybug genus Plotococcus Miller & Denno in Brazil,
with descriptions of two new species (Kondo, T., Gullan, P.J. Culik, M. and
Ventura, J.A., Studies on Neotropical Fauna and Environment), and a new genus
of African soft scale, Pseudocribrolecanium gen. nov.(Journal of Insect
Science). This last paper resulted from a collecting trip in June to Ghana sponsored by the PEET project that supports my
postdoctoral research at UC Davis. The trip to Ghana consisted of members from various Institutions including
the New York State Museum, Brigham Young University, and the University
of California, Davis. Geoff Morse who is conducting postdoctoral research in Davis at the Cranston and Gullan
lab until the end of 2005 was also a member of the expedition to Ghana and helped me collect the species that resulted in the Pseudocribrolecanium
paper. With a little bit of pressure, a lot of encouragement, patience and
cooperation by Lyn Cook, Geoff Morse, Penny Gullan and the students at the Cranston and Gullan lab, I have started a project aimed at
producing a genetic level phylogeny of the family Coccidae. In order to conduct
this study I have asked several of my colleagues, e.g. Gillian Watson, Ray
Gill, Chris Hodgson, Jon Martin, Mike Williams, Greg Hodges, and others for
help in obtaining alcohol or dried material for DNA extraction. I am still
short of many coccids for this work, and would like to ask for help. I
especially need specimens from coccids included in the subfamily Eriopeltinae
(e.g. Eriopeltis festucae, Luzulaspis spp., Poaspis spp.,
etc); Cyphococcinae (i.e. Cyphococcus Laing and Messinea
De Lotto); Cissococcinae (i.e. Cissococcus fulleri Cockerell);
Coccinae: Paralecaniini (Paralecanium spp., Fistulococcus spp., Austrolecanium
spp., Maacoccus spp., etc); and Filippinae (e.g. Ceronema spp., Filippia
follicularis, Kozaricoccus bituberculatus, Takahashia
japonica, etc.). I will appreciate coccids from other subfamilies as well.
Finally but not least, I would like to take this opportunity to express my
thanks to Lerzan Erkilic and M. Bora Kaydan and all those who organized the
successful ISSIS 2004 meeting at Adana, Turkey.
Lyn Cook, Australian National University, Canberra,
Australia: This year I have
been able to return to working on scale insects almost full time after spending
the past four years doing mostly plant systematics, evolution and
biogeography. I currently have funding
to work on scale insect-host plant interactions and continue to be primarily
interested in gall-inducing 'eriococcids'.
In June this year, I visited Penny Gullan's lab in California
and attended "scale camp", where it was good to catch up with other
coccidologists and talk scales. I've
also been lucky to have been able to go on several big field trips in Australia
(totalling more than six months over the past 4 years) and have collected many
new gallers - particularly eriococcid gallers of Myrtaceae. I have also continued to work on Apiomorpha and genetic data suggest that
the genus represents a cryptic species-radiation of well over 100 species; all
on Eucalyptus. Mike Crisp (ANU) and I are continuing
collaborations on plant systematics and hope to be able to test some hypotheses
of scale insect-host cospeciation. We
currently have an honours student (Robert Edwards) working on a molecular
phylogeny of Melaleuca, which will
feed into our studies of cospeciation between the newly discovered species
radiation of eriococcid gallers and their host Melaleucas. The undescribed
species (probably more than 30) appear to be most closely related to
eriococcids currently named "Sphaerococcus" ferrugineus and
"S." socialis. Some other
collaborative projects include the evolution of eriococcids that feed on Nothofagus (joint with Penny Gullan and
Nate Hardy), Matsucoccus systematics
(Penny G and Janie Booth) and a molecular phylogeny of Coccidae (primarily with
Demian Kondo). I would like to thank all
those coccidologists who have provided specimens and identifications for the
molecular systematics studies and hopefully papers will start to come out in
2006.
M.
Bora Kaydan, Ankara University, Faculty of Agriculture, Plant Protection
Department, Turkey: At last we have
finished the “Proceedings of the Xth International Symposium of Scale Insect
Studies” with Lerzan Erkýlýç; it was published this summer. Now I am working on
the scale insect fauna of the eastern part of Turkey. All summer I collected interesting species from unusual
and diverse locations. This project will continue two more years. I also have been studying mealybug-parasitoid
interactions. Some recent faunistic articles on scale insects were accepted by
“Acta Phytopathologica et Entomologica Hungarica”, “Bolletino di Zoologia
Agraria e di Bachicoltura” with the assistance of Dr. Kozár. Finally I am
planning to describe two new species of Atrococcus and Stipacoccus
and to prepare a list of mealybug species of Turkey because a lot of new species have been added in the last
five years.
Benjamin
Normark, University of Massachusetts, Massachusetts, USA, bnormark@ent.umass.edu.
The main focus of our laboratory continues to be on molecular systematics of
Diaspididae. We are always very grateful to receive samples of diaspidids
from anywhere. We are interested in the
genetic diversity of common pests, as well as the systematics of non-pests, so
virtually any sample with recoverable DNA (ideally in 100% ethanol) is useful
to us. We recently published one paper
on molecular systematics of the Aspidiotus
nerii complex (first author Lisa Provencher) in Annals of the Entomol. Soc. Am., and
another on molecular systematics across Diaspididae (first author Geoffrey
Morse) in Syst. Entomol. We have also recently submitted a third paper
(on the molecular phylogeography of an eriococcid, the beech scale Cryptococcus fagisuga, first author
Rodger Gwiazdowski) to Biological Control. Our next publication (including authors Geoff
Morse and Rosa Henderson) will probably be on the molecular phylogenetics of New
Zealand Leucaspis.
Ph.D. student Matthew Gruwell is doing his Ph.D. dissertation on the primary
endosymbionts of diaspidids; Ph.D. student Rodger Gwiazdowski is starting
dissertation work on the molecular systematics of Chionaspis, especially of the sexual/parthenogenetic species
complexes Ch. pinifoliae and Ch. salicis. Undergrad Jeremy
Andersen has done a lot of work this year to expand our sequencing effort
across Diaspididae and especially to develop the gene CAD new molecular marker
for inferring phylogeny in scales. And I
am still working to recruit another graduate student for a well-funded NSF
research assistantship: alert your undergraduate students. We all travelled to Davis
in June for the third Scale Camp, hosted by the Gullan lab, and learned from
Lyn Cook about how to do chromosome squashes and from Gillan Watson, Ray Gill,
and Penny about how to make good slides for morphological characters. Ray Gill gave us detailed maps and directions
to collecting sites -- and a truck! -- that enabled us to have a very
productive diaspidid safari in the Mojave.
I remain especially interested in the unusual genetic systems of scale
insects and related issues such as: sex ratios, sex determination, genomic imprinting,
ploidy levels of bacteriomes/mycetomes, and cytogenetics. One venue where
I was invited to speak about these issues was the Gordon Research Conference on
Epigenetics, where I was impressed to find researchers on the fundamentals of
gene regulation (e.g., Amar Klar of the National Cancer Institute) who are
interested in scale insect genetic systems, and who remember Spencer Brown and
Uzi Nur. Indeed, I met the world's
leading researcher on genomic imprinting in Drosophila -- Vett Lloyd of Mount
Allison University
in New Brunswick
-- and found her keen to start in on mealybugs.
SOO-jung SUH, South Korea suhsj97@npqs.go.kr: I am a new face
in the world of scale insects, and I would like to introduce myself. I am working
for the National Plant Quarantine Service (NPQS) and have been charged with the
identification of Coccoidea and Aleyrodidae. Actually I knew very little about
scale insects until last year, and I still consider myself a novice. I have
been interested in scale insects and whiteflies because they are major pests on
many plants in my country. I wanted to improve my identification skills, so I
trained with Greg Hodges for 11 months (from August 2004 to June 2005) at the
Division of Plant Industry, FDACS. This trip was a great experience for me and
I learned a lot about scale insects. I appreciate Greg's help and kindness and
I was very glad to meet Dug Miller and Greg Evans while I was in the United States. I returned home in July 2005 and started working on scale
insects and whiteflies of South Korea. I am particularly interested in the Diaspididae, so I
have been concentrating on the Korean armored scale insects. Currently only 69
species have been recorded as occurring in South Korea, but I think more species
are likely to be added in the future because neighboring nations, such as Japan
and China, have many more identified species than Korea. I am planning to start a new project that
will be a taxonomic revision of the Korean armored scale insects. I hope I can
find new species during the survey phase of the study and plan to finish the
project in 2009.
Vett Lloyd, Mt. Allision University, New Brunswick, Canada vlloyd@mta.ca: I'm a (very) recent convert to
the wonderful world of mealybugs. I've been working on genomic imprinting in Drosophila for many years and have
recently started to expand our work to Planococcus
citri. We're interested in studying the mechanism of genomic imprinting and
paternal chromosome elimination in mealybugs.
Greg Hodges, Division of Plant Industry, Gainesville, Florida : This past year
has been a very busy one for myself, my wife and my lab. My wife (Dr. Amanda
Hodges) is currently the entomology coordinator for the Southern Plant
Diagnostic Network () and one of her main objectives has been to organize
taxonomic workshops for taxonomists based at land grant universities in the
southeastern United
States. In
December 2004, I participated in one of these workshops () sponsored by the Southern Plant Diagnostic Network along
with Drs. Doug Miller, Gary Miller, Mike Williams, Greg Evans, Susan Halbert,
Chris Dietrich and Steve Wilson. There were approximately 32 participants at
the workshop and it was a lot of fun but a lot of work. Several nice
publications from the above taxonomists were generated from this workshop and
will be available in the December 2005 issue of the Florida Entomologist. Not
too long after our ‘Homoptera’ workshop, Amanda asked me to help with another
session. This time it was all about pink hibiscus mealybug (Maconellicoccus
hirsutus) and all the various mealybugs that we routinely encounter in Florida. This past year I also hosted a very promising visiting
scientist from South
Korea. Her
name is Dr. Soo Jung Suh and she spent 11 months with me learning about the
taxonomy of the Coccoidea and also the Aleyrodidae. From her visit, we have
generated four publications that will be out soon. Soo left my lab this past
June and returned to South Korea where she has been asked to be the primary scale
insect/whitefly identifier for the National Plant and Quarantine Service for
her country. In October 2005, I had another visiting scientist spend time with
me. Her name is Nereida Mestre Novoa from Cuba. She is currently finishing up her dissertation and
working on the Coccidae of Cuba. This
has also been an active year on the pest front for Florida. The pink hibiscus mealybug has continued to give us
problems, especially in getting into new areas due to plant movement. The
lobate lac scale (Paratachardina lobata (Kerriidae)) is still a major
pest for south Florida and we now have about 300 host records for this scale in Florida alone. We have also seen the spread of Duplachionaspis divergens (Diaspididae)
within our state this year and it looks as though it may have the potential to
be nasty little pest for some of our ornamental grasses. If any of you ever get
a wild hair to come my way, please know that you are all welcome. Just drop me
a line () and let me know when or if you need specimens.

Gregory Evans, Beltsville, Maryland, USA,
Gregory.A.Evans@usda.gov. After many
years working with scale insect systematists, Dug Miller, Avas Hamon and Greg
Hodges, I was given the privilege of joining the ranks in June 2004 as the
National Coccidology Specialist for USDA/APHIS, a position previously occupied
by Doug Odermatt (retired). My primary duty is to identify species of scale
insects and whiteflies intercepted at the U.S.
ports-of-entry. Several new species have been intercepted, particularly by Bert
Lindsey (APHIS, Los Angeles), that
I plan to describe with Dug Miller, who has been extremely helpful to me. We
are also working together with Dr. Alessandra Rung to resolve the taxonomic
status of Planococcus citri versus P. minor by a combination of
morphological and DNA studies. I am especially grateful to André Panis for
collecting and sending specimens of Planococcus
citri from the type locality in France
for our study. John Dooley (APHIS, San Francisco)
and I are working on keys to the scale insects and whiteflies found on bananas.
I continue to work on the systematics of aphelinid parasites of scale insects,
aphids and whiteflies when I can.
Dug Miller and
Alessandra Rung, Beltsville, Maryland, USA: Our
major projects have been to complete expert system keys for the identification
of scale insects intercepted at U. S.
ports-of-entry. To date a family key http://www.sel.barc. usda.gov/ scalekeys/all_families.htm
and mealybug key http://www.sel.barc.usda.gov/scalekeys
/NET/Mealybugs.html are available on line.
We currently are working on a soft scale key but are having difficulty
finding funds to support the effort. The
newest in the series of catalogs that has been published as a result of
ScaleNet is A systematic catalogue of the Cerococcidae, Halimococcidae,
Kermesidae, Micrococcidae, Ortheziidae, Phenacoleachiidae, Phoenicococcidae,
and Stictococcidae of the world which was published in 2005 by Intercept (see http://www.intercept.co.uk). I have just submitted the last of our
ScaleNet-based catalogs on the Diaspidinae, Leucaspidinae, and Ulucoccinae to
the American Entomological Institute (AEI); this has been a major task because
it contains 1600 camera ready pages.
Unfortunately, Intercept was bought out by a French company Lavoisier
and they were not interested in continuing to publish the volumes produced
through ScaleNet. We also are pleased to
announce that the book that John Davidson and I have been working on for nearly
30 years is now in print “Armored scale insect pests of trees and shrubs.” It is available from Cornell University Press
at http://www.cornellpress.cornell.edu/cup_order.html. Douglas Williams and I have just completed a
manuscript on the armored scale genus Furcaspis
which we also hope will be published by AEI. The other big news is that I am considering
retiring in January of 2007 after 37 years with the US Department of
Agriculture. This gives me a year to
clean up all of the projects that are still in process and to straighten things
out in the collection so that the next person here will begin with a clean
slate. One important project for 2006 is
to obtain cabinets for the slide collection so that we can incorporate the
Kosztarb collection. We have written
several proposals for funding, but have yet to succeed. The Miller Hotel has had a few visitors this
year including Amanda and Greg Hodges, Douglas Williams, Janie Booth, and Cory
Unruh.
Douglas Williams,
The Natural History Museum, London, UK:
For some reason I am unable to convince Douglas
to write something for “The Scale” so I (Dug Miller) am writing something for
him. The problem is, I miss a lot, and
probably misrepresent his numerous accomplishments. In terms of travel, I know that he visited Beltsville,
Maryland so that we could finish a paper on
the armored scale genus Furcaspis. He also visited with his colleagues Danièle
Matile and Imre Foldi in Paris
where he is working on species of Stictococcus
and other genera. He seems to have new
papers coming out several times each year and I hope that we have caught most
of them in ScaleNet. When he is home, I
know he spends considerable time drawing the many exciting new scales that come
across his desk; his major current works are on Protortonia and the Iceryines with Penny Gullan.
Michael Kosztarab,
Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA: Michael professionally had a
productive year by seeing four of his articles published. He was fortunate last May to meet three of
his former graduate students: Avas Hamon and Michael Williams in Beltsville,
Maryland, during the celebration honoring the still living US Department of
Agriculture aphidologist [and coccidologist] Louise M. Russell. In Regensburg,
Germany Michael also met
former graduate student Gema Perez Guerra and her family. Michael is serving for the third year in a
row as the faculty adviser for the Virginia Tech Hungarian Student
Association. Michael’s main hobby and
pastime remains working in the garden and greenhouse. [Extracted from a holiday
letter].
Agatino Russo, Gaetana Mazzeo and Pompeo Suma, Istituto
di Entomologia Agraria, Catania, Italy: We are still working on the systematics of the Coccoidea,
and faunistic and physiological aspects of the Pseudococcidae. Currently we are
involved in studies on species living in Sicilian protected natural
environments that are poorly known, and about species newly introduced through
commerce of ornamental plants. A paper is in progress on the species related to
succulents. A national research project
is underway on the side effects of insecticides on the citrus mealybug and its
parasitoids. Initial results have been presented in National and International
Congresses (OILB, IOBC, Congresso Nazionale Italiano di Entomologia) and have
been published. Next year we will begin
research on populations of Planococcus citri in Sicily to distinguish them from other populations in the Mediterranean Basin using molecular tools; similar studies will be carried out
on P. citri parasitoids.
Jon Martin, The Natural History Museum, London, UK : NHM scales on the move:
The big news in the collections world has been the move of the entire entomological collection of London ’s Natural History Museum during 2005. This has been to allow demolition of the Entomology building to make way for the creation of Phase 2 of the museum’s “Darwin Centre”. For the scale insect collections, Jon Martin began preparing in earnest in 2004, with a complete overhaul of the dry collections. Several separate collections, including the former Newstead and Green collections, were amalgamated into one. This “new” dry collection comprises small shunt boxes and small glass-topped boxes, and is alphabetically arranged according to up-to-date name combinations, making location of any named taxon much easier and quicker. The slide collections, already in much better order than the dry collections had been, were prepared for shipping by tightening the rows of slides to minimise movement. Several cabinets required attention to drawer handles and locks, to allow all cabinets to be secured. The scales, along with Lepidoptera and parasitic Hymenoptera, began their journey in June 2005. Their new location is some 4 miles from the main South Kensington museum, at Wandsworth (Southfields) and physically close to the Wimbledon tennis ground. By the end of October, approximately 100,000 coccoid slides and over 8,000 boxes of dry scales had been trucked across London , along with 82,000 drawers of Lepidoptera, their cabinets and the Entomology Library – not to mention 25 staff and their working environment. Once settled in, some distortion of wooden cabinets led to drawer-jamming and the whole coccoid and whitefly dry collection was then re-rehoused in metal “Dexion” drawer units, which was a job that Jon could have done without. Fortunately, settling has not led to such major problems with the wooden “Hill” slide cabinets. After the inevitable closed period, Gillian Watson (California Department of Agriculture) became the first visitor to the NHM scales’ new location in November. At the time of writing Ferenc Kozar ( Hungarian Academy of Sciences) is putting the new system through its paces. In theory at least, the whole process will be reversed in 2008 or 2009, with Darwin Centre 2 due to accommodate as much as possible of the NHM’s entomological collection. For now, the temporary arrangements are functioning well. The 4 th floor of the old building, which many coccidologists will recall (fondly, we hope!), is already but a memory.

insect, Parlatoria oleae Clovee (Homoptera: Diaspididae) and its
parasitoids in Upper Egypt. (In English; Summary In Arabic). Assiut Journal of
Agricultural Sciences 35(3): 197-208. [AbouEl2004]. Notes: The population fluctuations of P. oleae
were studied in two regions of Assiut Governorate (Sahel-Selim and Assiut
College Farm), Egypt, during 2002 and 2003. The pest population decreased gradually from
January till April and then increased to reach its maximum level of abundance
in September 2002 and October 2003 in Sahel-Selim. The average mean number of P.
oleae was 512.83 and 626.5 individuals/50 leaves during 2002 and 2003,
respectively. Approximately, the same trend occurred in Assiut College Farm,
except that the population of the pest was very low compared with that at
Sahel-Selim. Three P. oleae parasitoids, Encarsia aurantii,
Aphytis chrysomphali and Aphytis diaspidis, were found in
Sahel Selim, while A. diaspidis was the only parasitoid species
recovered from Assiut College Farm. The first two parasitoids, E.
aurantii and A. chrysomphali, are considered as first
record on the olive scale insect in Assiut. The effects of weather factors
(minimum and maximum temperatures as well as relative humidity) on the
population of the pest and its parasitoids and the effects of these parasitoids
on the population of the pest were also determined in Sahel-Selim.

parathion-methyl (Folidol 600 CE at 100 ml/100 litre) in 2002 to control P.
persicae in vineyards was investigated in a field experiment in Monte
Belo do Sul, Rio Grande do Sul, Brazil. The insecticides were sprayed using 800
litre of water/ha seeking third instar nymphs. Fenitrothion, methidathion,
parathion-methyl, trichlorfon, imidacloprid and thiamethoxam were efficient for
P. persicae control. Dimethoate and thiacloprid reduced pest
population levels below 50%.

C., Llanderal-Cázares, C., Soto-Hernández, M. & Castillo-Márquez, L.E. 2005. Cochineal (Dactylopius coccus
Costa) production in prickly pear plants in the open and in microtunnel
greenhouses. (In English; Summary In Spanish). Agrociencia (Montecillo) 39(2):
161-171. [AldamaLlSo2005]. Notes:
Some countries produce cochineal in the open to obtain carminic acid as a
natural red dye. In México, this is done on protected cut cladodes because of
the environmental conditions, natural enemies, and competitors. This results in
a disadvantage when compared to production in other countries. For this reason,
prickly pear plants (Opuntia ficus-indica) found in the open and
protected in two types of microtunnel greenhouses were infested. Fresh and dry
weight, carminic acid content, length of the biological cycle, the presence of
natural enemies of the cochineal, as well as the resistance of the plant in
various cycles were evaluated. The microtunnel made of transparent plastic was
the best treatment to produce cochineal. The plants in this microtunnel resisted
three cycles, while the ones in the green raffia canvas resisted two cycles.
The length of the biological cycle decreased when the temperature increased and
was lower in the greenhouses than in the open. The carminic acid content ranged
between 19.4 and 22.9%. The predators of D. coccus found were Baccha
sp., Laetilia coccidivora, Hyperaspis trifurcata, Sympherobius
sp. and the competitor D. opuntiae.

Notes: Several alternatives for C. montrouzieri
artificial rearing were tested. They were: the use of Galleria mellonella
eggs, aphid colonies and banana plants infested with the mealybug Dysmicoccus
bispinosus [D. texensis]. C. montrouzieri was able to
feed itself and complete its life cycle over the three assayed substrates. No
deformations on C. montrouzieri larvae, pupae or adults were
observed. The adults obtained were used as parental for the next generation.
This method could be recommended for Cuban laboratories where C.
montrouzieri is massively reared.

products are widely used for food coloration in Japan. An investigation concerning the photo-mutagenicity
and photo-carcinogenicity of frequently used colorants in Japan was performed. Colorants examined were from Laccifer
lacca (lac-color), Coccus cacti (cochineal-color), Carthamus
tinctorius (carthamus yellow), Gardenia augusta (gardenia yellow and gardenia blue), Monascus
anka and Monascus purpureus (monascus red), the skin of Vitis
vinifera and V. labrusca (grape-skin color), Tamarindus
indica (tamarind brown) and Beta vulgaris (beet red). No
significant increase in bacterial mutation was found when Salmonella
typhimurium TA98, TA100 and TA102 were simultaneously treated with
colorants and subjected to UVA irradiation for 30 min. When colorant solutions
were subjected to UVA irradiation for 4 h, irradiated solutions containing
lac-color became slightly mutagenic toward S. typhimurium TA98
without metabolic activation. A decrease in cell survival resulted when WTK-1
cells were subjected to UVA irradiation for 60 min in the presence of purpurin
at 1 mg/ml. Delayed cytotoxicity was also observed following 24 h incubation in
fresh medium of samples that were subjected to UVA irradiation for 60 min in
the presence of colorant (carthamus yellow, grape-skin color, gardenia blue,
cochineal-color, monascus red or purpurin).

scanning electron microscopy (SEM) and low temperature scanning electron
microscopy (LTSEM). Beauveria bassiana, Lecanicillium dimorphum
and Lecanicillium cf. psalliotae, were inoculated
directly on the scale insects or on insect infested plant material. We found
that L. dimorphum and L. cf. psalliotae
developed on plant material and on scale insects, making infection structures. B.
bassiana was a bad colonizer of date palm leaves (Phoenix dactylifera L.) and did not parasitize the scale insects.

yanonensis causes damage on ornamental citrus fruit in Menton,
France. To reduce its population, the town decided to use
biological control which is more environmentally friendly. A specific parasitic
wasp, Aphytis yanonensis, already introduced in France from Japan, was collected on the trees of the town. The rearing,
maintained by the INRA laboratory of Valbonne, aimed at producing parasitoids
by augmentative releases to control the pest. The parasitoid was quite well
acclimatized and the rate of parasitized scales increased after releases.
However, Aphytis yanonensis seems not to be established and could
not be really efficient unless by renewed releases each year.

Under' - Diversity, endemism and evolution of the Australian insect fauna:
examples from select orders. Australian Journal of Entomology 43: 216-234.
[AustinYeCa2004]. Notes: The
Australian insect fauna is highly endemic and characterised by numerous unique
higher-level taxa. In addition, a number of groups are noticeably absent or
depauperate on the continent. Many groups found in Australia show characteristic Gondwanan distribution patterns
on the southern continents. There are extensive radiations on the plant
families Myrtaceae and Mimosaceae, a specialised arid/semiarid fauna, and
diverse taxa associated with rainforests and seasonally wet tropical regions.
The fauna is also poorly studied, particularly when compared with the flora and
veterbrate groups. However, studies in the last two decades have provided a
more comprehensive picture of the size of the fauna, relationships, levels of
endemism, origins and its evolution. Here we provide an overview of these and
other aspects of Australian insect diversity, focusing on six groups, the
Thysanoptera and the five megadiverse orders Hemiptera, Coleoptera, Diptera,
Lepidoptera and Hymenoptera. In the section on Hemiptera, the genera Cystococcus
and Callipappus are discussed, as well as Icerya purchasi.

Notes: The evaluations were conducted weekly in the vegetative
and blooming/fructification phases in four quadrants (N, S, E, W) of the plant.
2,230 specimens of S. articulatus were collected in the vegetative
phase and 1,006 in the blooming/fructification, therefore, 59,8% adults. From
the total of 965 P. egena, 416 were immatures and 549 adults. The
main conclusions are: (I) M. communis may be useful as plant
bait; (2) this plant may be cultivated or not around the crops of economic
importance because it may function as a reservoir of the pest or of its natural
enemies; (3) the relationship of predator/prey/plant quadrant/phenology phases
was, respectively, 1.14:1.0 and 1.0:1,08 in north and east quadrant; while in
the south and west quadrants it was 1.0:2.26 and 1.0:2.80; and, (4) the
predation of S. articulatus by P. egena was, on
average, 1.0-2.8 nymphs and 1.66-4.44 adults (in vegetative phases) and
1.0-3.76 and 1.0-3.98 (in blooming/ fructification) with significant
differences at P 0.01.

honey production of Marchalina hellenica (Coccoidea:

Insectology 57(2): 127-130. [Bacand2004].
Notes: M. hellenica is an important
honeydew-producing scale insect useful to apiculture and endemic in the pine (Pinus
halepensis) forests of Greece. Until 1995, this insect was known to be monophagous
on certain species of the genus Pinus. From 1995 onwards, several
attempts were made to establish M. hellenica on fir trees, A.
cephalonica, on Mt. Helmos (Greece). In 1995 and 1996, inoculation treatments, either
with 2nd instar insects or with adult individuals, were used for the
establishment of the insect on fir trees. These trials were successful and for
the first time in 1999, honey was collected, the physicochemical
characteristics of which suggest that the honey was of good quality. These
results create the necessary preconditions for the increase in honey production
derived from the honeydew secretions of M. hellenica.

Société Entomologique de France 40(2): 169-176. [BacandSaPa2004]. Notes: Marchalina hellenica
is a scale insect, endemic in pine (Pinus halepensis) forests of Greece and other Mediterranean countries, which plays a
major role in the production of honeydew honey. We investigated the
morphological and the biological characteristics of M. hellenica
in the pine forests of Mt. Parnis in comparison with those in the high-altitude fir (Abies
cephalonica) forest of Mt. Helmos where it has been recently established, after
anthropogenic intervention. Morphologically, the final body size of the 1st
instar and the adult stages of M. hellenica in the fir forest
were equal to those in the pine forest. Biologically, in the fir forest, the
insect exhibited a long 1st instar's period, which was the stage of its
overwintering. In the pine forest, the 1st instar period was short and the
insect overwinters in the stage of 2nd instar. The number of eggs per female in
the fir forest was quite low (25-145) compared with the number of eggs in the
pine forest (200-300). Concerning the qualitative parameters of the resulting
honeydew-honey, statistically significant differences were found in Diastase
and HMF (p<0.0001). No difference was found in sucrose, fructose + glucose
and water content, neither to electrical conductivity and total acidity. All
values were within the EU limits (EU Directive 2001).

and field experiments were carried out in 2003 to determine the efficacy of F.
larvarum in controlling the black oak scale, T. vitis. F.
larvarum was the only entomogenous fungus that is active in the area. A
high infestation level (60.4%) by the fungus was recorded in abandoned
orchards, whereas it was almost negligible in 13 commercial orchards. Limited
effects of parasitoids and predators were recorded in the experimental fields.
Only in 2 out of 13 vineyards were T. vitis observed to be
attacked by the parasitoid Coccophagoides moeris. The most common
predators observed were Lestodiplosis spp. and members of the
family Rhaphidiidae.

hirsutus (Green) using insect growth regulator. Research on Crops 6(1):
68-71. [Balika2005]. Notes: A
field trial was conducted during the 2000/01 rabi season to evaluate the
efficacy of buprofezin (Applaud 25 SC), applied at 1125, 1500 or 2250 ml/ha,
against the grape mealy bug. Results revealed that 10 days after the 1st, 2nd
and 3rd sprays, buprofezin at 2250 ml/ha recorded the least number of mealy bug
colonies per vine (27.7, 19.3 and 8.2, respectively) and was at par with
buprofezin at 1500 ml/ha, which in turn was at par with buprofezin at 1125
ml/ha. Similarly, 10 days after the 1st, 2nd and 3rd sprays, buprofezin at 2250
ml/ha recorded the least number of mealy bug colonies per bunch (6.8, 2.9 and
2.0, respectively), followed by buprofezin at 1500 and 1125 ml/ha which were at
par with each other. The lower dosage of buprofezin 25 SC (1125 ml/ha) along
with fish oil rosin soap (Meenark) at 3125 g/ha can be recommended for the
management of mealy bugs on grape vines and bunches.

Variation in the degree of coupling between delta C-13 of phloem sap and
ecosystem respiration in two mature Nothofagus forests. New
Phytologist 166(2): 497-512. [BarbouHuDu2005].
Notes: Day-to-day variability in the carbon isotope composition
of phloem sap (delta C-13(hd)) and ecosystem respiratory CO2 (delta C-13(R))
were measured to assess the tightness of coupling between canopy photosynthesis
(delta C-13(hd)) and ecosystem respiration (delta C-13(R)) in two mature Nothofagus
solandri (Hook. f.) forests in New Zealand. Abundant phloem-tapping
scale insects allowed repeated, nondestructive access to stem phloem sap 1-2 m
above ground. delta C-13(hd) was compared with delta C-13 predicted by an
environmentally driven, process-based canopy photosynthesis model. Keeling
plots of within-canopy CO2 were used to estimate delta C-13(R). By including a
lag of 3 d, there was good agreement in the timing and direction of variation
in delta C-13(hd) and predictions by the canopy photosynthesis model,
suggesting that delta C-13(hd) represents a photosynthesis-weighted,
integrative record of canopy photosynthesis and conductance. Significant day-to-day
variability in delta C-13(R) was recorded at one of the two forests. At this
site, delta C-13(R) reflected variability in delta C-13(hd) only on days with
< 2 mm rain. We conclude that the degree of coupling between canopy
photosynthesis and ecosystem respiration varies between sites, and with
environmental conditions at a single site.

Family Margarodidae (Hemiptera: Coccoidea) of the World. Intercept Ltd., Wimborne, U.K.. 400 pp. [BenDov2005a]. Notes: This catalogue of the scale
insect family Margarodidae (Hemiptera: Coccoidea) includes data on 442 species
and subspecies that are placed among 77 genera. The family Margarodidae
includes some destructive pests of agricultural crops such as citrus, coconut,
grapevine, mango, oil palm, deciduous fruit trees, forest trees and
ornamentals. On the other hand, several margarodid species are beneficial
insects, as they produce components of economic importance. This book is a synthesis
and catalogue of all the information published on these genera, species and
subspecies worldwide from 1758 to December 2003, plus several works published
in 2004. Data are provided on their correct scientific names, taxonomy, common
names, synonyms, host plants, distribution, natural enemies, biology, economic
importance and published references. Neomargarodes cucurbitae
Tang, 2000 is homonym and n. syn. of Neomargarodes cucurbitae
Tang & Hao, 1995. Four new combinations are introduced in this Catalogue,
namely, Margarodes australis (Jakubski) n. comb., Margarodes
floridanus (Jakubski) n. comb. Margarodes sinensis
(Silvestri) n. comb. and Margarodes williamsi (Jakubski) n. comb.
The generic name Porphyrophora Brandt, 1833, is regarded as a nomen
protectum, while Coccionella Hahnemann, 1793 as a nomen
oblitum and a synonym of Porphyrophora.

research is the phytosociological study of some typologies of semideciduous and
evergreen wood vegetation of the Apulia region, in the southeast of peninsular Italy. The associations, which have been defined on the
basis of 152 phytosociological relevees and elaborated by cluster analysis
methods, are: the Aleppo pine woods (Thymo capitati-Pinetum halepensis
and Cyclamino hederifolii-Pinetum halepensis ass. nova), the cork
oak woods, which in Apulia find the eastern limits of their distribution (Carici
halleranae-Quercetum suberis ass. nova), the kermes oak shrubbery (Arbuto
unedi-Quercetum calliprini) and woods (Hedero helicis-Quercetum
calliprini ass. nova), the holm oak woods, which represent the major
vegetational potentiality of the region (Cyclamino hederifolii-Quercetum
ilicis, Cephalanthero longifoliae-Quercetum ilicis and Festuco
exaltatae-Quercetum ilicis), the Trojan oak woods, which find the
western limits of their distribution in the area of Murge, between Apulia and
Basilicata (Euphorbio apii-Quercetum trojanae and Teucrio
siculi-Quercetum trojanae), and the woods of Quercus virgiliana
(Irido collinae-Quercetum virgilianae ass. nova and Cyclamino

0405.htm] The pink hibiscus mealybug (PHM) can destroy more than 200 plant
species by injecting them with toxic saliva while sucking their sap. The exotic
insect pest recently invaded California and Florida, and has proven difficult to monitor and kill, partly
because their waxy outer coating, or cuticle, resists penetration by
conventional insecticides. But ARS scientists have now found a way to lure male
mealybugs with pheromones, making them easier to detect.

The SOFM type neural networks in the process of identification of selected
orchard pests. (In English; Summary In Polish). Journal of Research and
Applications in Agricultural Engineering 49(4): 5-9. [BoniecPi2004]. Notes: One of the advantages of the
Kohonen type neural network, called also as SOFM (Self Organizing Feature
Maps), is the ability of the discussed neural network to determine the degree
of similarity occurring between classes. The SOFM network can be also used to
detect regularities occurring in the obtained empirical data. If at the network
input, a new unknown case appears which the network is unable to recognize, it
means that it is different from all the classes known previously. The SOFM
network taught in this way can serve as a detector signaling the appearance of
a widely understood novelty. Such a network can also look for similarities
between the known data and the noisy data. In this way, it is able to identify
fragments of images presenting photographs of e.g. orchard pests. The purpose
of this research was to use the SOFM neural networks in the process of
identification of 5 selected orchard pests, namely Dasyneura mali, D. piri, Parthenolecanium corni, Zeuzera pyrina and Cossus cossus. The desirable
features enable the Kohonen neural network to identify the pests correctly
based on the presentation of images not originating from the teaching set, i.e.
noisy photographs taken under different light exposure conditions and using
different qualities of the equipment.

German; Summary In English). Gesunde Pflanzen 57(1): 18-26. [BorowkHeHu2005]
Notes: Biological plant protection is considered an important part of
integrated pest management (IPM) and may eventually culminate in global
resource management. IPM involves all factors that are suitable for and
contribute to "a unified programme to manage pest populations so that
economic damage is avoided and adverse side effects to the environment are
minimized". Unfortunately, the entomological challenges in the direction
of global resource management are only minor aspects of the task to be solved.
Efforts to control a number of pests on cassava in East Africa, specifically in
the Republic of Malawi, must focus on the cassava mealy bug Phenacoccus
manihoti, but also on the green cassava mite Mononychellus
tanajoa, the grasshopper Zonocerus elegans, and the bacterial
disease Xanthomonas campestris pv. manihotis [X. axonopodis
pv. manihotis]. Moreover, the effective management of these insects and
microorganisms needs also to consider external, particularly sociological and
economic factors that currently interfere with the best efforts of the
scientists involved. These external factors are a formidable challenge to the
best scientific state of the art available. In view of our experiences in East Africa, we propose to transform IPM into a system of Integrated Production
(IP) as a generally applicable, sustainable, long-term strategy for global
plant protection. If adopted, this would be a move into the direction
envisioned by delegates at the World Conference at Rio de Janeiro.

pastures. In Australia, similar problems with H. summervillei
were observed in 1926 on Pasaplum grass in a pasture. In New Caledonia, the phenomenon was studied from 1998 to 2003 on the
main island, and the results are given here. Like in Australia, a natural reduction of populations was observed, so
pronounced that the species is supposed to be extinct locally. The factors were
not determined.

& Ferraro, M. 2004. Germline cyst
development and imprinting in male mealybug Planococcus citri.
Chromosoma. Berlin 113(6): 284-294. [BugliaFe2004]. Notes: In the epigenetic modifications
involved in the phenomenon of imprinting, which is thought to take place during
gametogenesis, one of the primary roles is exerted by histone tail
modifications acting on chromatin structure. What is more, in insects like
mealybugs, with a lecanoid chromosome system, imprinting is strictly related to
sex determination. In many diverse species gametes originate in specific,
highly evolutionarily conserved structures called germline cysts. The use of
staining techniques specific for fusomal components like F-actin has allowed us
to describe for the first time the morphogenesis of male germline cysts in the
mealybug Planococcus citri. Antibodies to anti-methylated lysine
9 of histone H3 (MeLy9-H3) and anti-heterochromatin protein 1 (HP1) were used
during cyst formation to investigate the involvement of these epigenetic
modifications in the phenomenon of imprinting and their possible concerted
action in sex determination in P. citri. These observations
indicate: (i) a specific role for F-actin in the segregation, typical of the
lecanoid chromosome system, of genomes of paternal origin; (ii) that the two
vital gametes originating from a given meiosis, although carrying the same
genome, differ in the levels of both MeLy9-H3 and HP1, one of them being more heavily
labelled by both antibodies.

2004. Parasitoid behaviour: predicting field from laboratory. Ecological
Entomology 29(6): 657-665. [CasasSwMu2004].
Notes: Most of what is known about parasitoid behaviour comes from
laboratory observations: field quantitative observations on searching
parasitoids are extremely difficult to do and are rare. The basic components of
Aphytis melinus's response to California red scale (Aonidiella aurantii) were
studied in the laboratory: encounter, rejection, drumming, probing,
oviposition, and host-feeding. It was then asked whether these observations
provided a reliable guide to behaviour in the field in a situation that was
very different from the laboratory. Field observations were carried out on bark
on the trunk and interior branches of trees where live scale density is
extremely high in patches, dead scale make up 90% of all scale, and could be
expected to interfere with Aphytis search. The laboratory
observations predicted well the time taken in the field for each basic event
(drumming or probing) and average times spent on a scale. Also well predicted
were the distributions of times spent on drumming, probing, and total time on a
scale. Rejection rates were much higher in the field. Thus, the laboratory
studies predicted foraging behaviour in the field with variable success;
potential explanations for observed mismatch between laboratory and field and
its possible larger implications are discussed.

determine the characteristics of lac foraging behaviour of Kerria lacca
and its preference to host branch in foraging. Results showed that K.
lacca hardly hosted on branches over two years old and the distribution
of lac insects on branches had no relation to orientation. The diameter of
hosted branches ranged from 0.47-1.60 cm. On erect branches, K. lacca
was distributed around the branch but on most declining branches, K.
lacca only settled on the shaded parts. Comparison anatomy showed that
the periderm and cortex of two-year-old branches were thicker than those of
one-year-old branches. Furthermore, the layer of sclereids and fibres in
two-year-old branches was thicker than that in one-year-old branches by 27
micro m. The distance from periderm to phloem of 2-year-old branches was
farther than that of one-year-old branches. The periderm and cortex of the
upper parts of the branches were thinner than the basic parts of the branch.
The phloem of parts reached by sunlight was thinner than the shaded parts.
Furthermore, the keratinization of host tree suberin and tinsel on the epiderm
also inhibited K. lacca foraging.

Notes: There are 30 scale insect species which have been
intercepted from agricultural products coming into Taiwan by quarantine workers at customs. This study
attempted to develop a molecular diagnostic technique (polymerase chain
reaction-restriction fragment length polymorphism, PCR- RFLP) using genomic DNA
markers (ribosomal DNA, rDNA) for identifying 16 scale insect species. NS7 and
ITS6 primer sets were used to amplify ITS1 and its flanking regions of rDNA
from genomic DNA as a template extracted from a single specimen. DNA extracted
from these 16 scale insect species yielded a single fragment after PCR amplification.
These PCR products were then cut with various restriction endonucleases in
order to compare the results of restriction fragment length polymorphism. Our
results also reveal that it is possible to discriminate these 16 scale insect
species based on the species-specific patterns acquired from digesting the PCR
products with the endonucleases, TaqI, MspI, and HaeIII. Furthermore, we also a
set up a molecular key for these 16 scale insect species based on their RFLP
digestion patterns.

2005. Development of Diomus austrinus Gordon (Coleoptera:
Coccinellidae) on two mealybug prey species at five constant temperatures.
Biological Control 33(1): 39-48. [ChongOeOs2005]. Notes: Diomus austrinus
Gordon is a generalist mealybug predator native to southern Florida. The objective of this study was to provide
information on the development and survival of D. austrinus when
reared on two common mealybug species [the Madeira mealybug, Phenacoccus madeirensis Green, and the citrus
mealybug, Planococcus citri (Risso)] at five constant
temperatures (15, 20, 25, 30, and 35 deg C). Results of this study demonstrated
the efficacy of D. austrinus as an egg predator of mealybugs
within the temperature range found in greenhouses. D. austrinus
successfully completed development on both mealybug species, with larval
development requiring 1-4 days longer on the citrus mealybug than on the Madeira mealybug. D. austrinus feeding on the Madeira mealybug completed development in 15 days at 20 deg C, 22 days at 25
deg C, and 39 days at 30 deg C. The lower and upper larval developmental
thresholds of D. austrinus appeared to be 15 and 35 deg C,
respectively. Estimates of lower developmental thresholds using a linear model
agreed with the observed results. Survival of D. austrinus from
egg to adult among temperature/prey species combinations ranged from 60 to 90%.
In all temperature/prey species combination, the cohorts were slightly
female-biased, with an average proportion of females of 0.53. Females reared on
Madeira mealybugs at higher temperatures were generally
larger than those reared on citrus mealybugs.

[DimetrAb2004]. Notes: The
red-striped soft scale insect Pulvinaria tenuivalvata (Hemiptera:
Coccidae) started to infest sugarcane plants (Saccharum officinarum)
in different districts of Egypt during the last decade. The percentage of infestation
was recorded in El-Wakf area, Qena Governorate (Naghhamadi mill zone) in Upper Egypt in some fields. There were three levels of infestation, i.e. low,
intermediate and high. From these fields, samples were selected for physical
and chemical studies. The results showed that the stalks of infested plants
decreased in weight and the sugar content (glucose and sucrose) was drastically
reduced. The primary and secondary humidity and the cellulose content also
increased in the healthy plants compared to the infested ones. All the physical
characters of the infested plants were significantly affected in comparison
with the healthy ones.

their hosts speciate. Totally congruent phylogenies of interacting taxa have
not been observed often but a number of studies have provided evidence that
various hemipteran insect taxa and their primary bacterial endosymbionts share
phylogenetic histories. Like other hemipterans, mealybugs (Pseudococcidae)
harbour multiple intracellular bacterial symbionts, which are thought to be strictly
vertically inherited, implying codivergence of hosts and symbionts. Here,
robust estimates of phylogeny were generated from four fragments of three
nuclear genes for mealybugs of the subfamily Pseudococcinae, and a substantial
fragment of the 16S-23S rDNA of their P-endosymbionts. Phylogenetic congruence
was highly significant, with 75% of nodes on the two trees identical, and
significant correlation of branch lengths indicated coincident timing of
cladogenesis. It is suggested that the low level of observed incongruence was
influenced by uncertainty in phylogenetic estimation, but evolutionary outcomes
other than congruence, including host shifts, could not be rejected.

453-455. [Dragan2004]. Notes: The
armored scale insect, P. pentagona, is an important agricultural
pest, currently restricted to the southwest region of Bulgaria around the towns of Petrich and Sandanski. Dead
insects were observed in a peach orchard near Petrich and over 200 specimens
with evidence of fungal infection were collected in spring 2001 and 2002. The
fungal infections were caused by a pathogen belonging to the species Fusarium
larvarum (Nectria aurantiicola), which has never previously been
reported from Bulgaria. The fungus was isolated in pure culture.

A simple gravimetric technique for estimating honeydew or nectar production. New Zealand Journal of Ecology 28(2): 283-288.
[DunganBeWa2004]. Notes: We
describe a simple gravimetric technique for measuring the standing crop or
production of carbohydrate-rich solutions such as honeydew or nectar. Simulated
honeydew was sampled by absorbing droplets of solutions of known concentration
and volume with dried and weighed pieces of filter paper. The change in mass of
the paper after redrying provides an estimate of the total solution carbohydrates.
This method was compared with a widely used technique, whereby the volume and
concentration of droplets is measured with microcapillary tubes and a sugar
refractometer. A factor was derived to convert gravimetric refractometer
readings (g sucrose 100 g SUP -1 solution) to volumetric carbohydrate
concentration (g carbohydrate 100 ml SUP -1 solution) for the simulated
honeydew solutions. There was no difference in the ratio of
measured-to-expected carbohydrate mass between the 2 techniques, showing that
the quick, easy, and accurate filter paper method is appropriate for measuring
carbohydrate-rich solutions. The technique was developed to aid the study of
honeydew production by scale insects (Ultracoelostoma spp.) in New Zealand beech (Nothofagus spp.) forests.

Mediterranean Plant Protection Organization. 2004. Unaspis citri. Bulletin OEPP 34(2): 299-301.
[EMPPO2004]. Notes: Unaspis
citri is a serious pest widely distributed on citrus throughout the
main citrus-growing areas of the world. It is often detected on consignments of
citrus fruits in international trade. It has been reported to attack plants of
12 different genera belonging to 9 families, but it seems to prefer Rutaceae.
Other hosts include: Annona muricata, Musa paradisiaca, Cocos nucifera,
Psidium guajava, Ananas comosus, Artocarpus heterophyllus and Tillandsia
usneoides. The origin of U. citri is in South-East Asia and it is now present in Australia, North, Central and South America, Pacific Islands, Egypt, Syria and China. Topics covered include synonymy, taxonomic position,
detection, identification, and comparisons to similar species.

Mealybugs may have met their match: Insect predators and parasites home in on
this growing menace. Agricultural Research Magazine 53(4). [Flores2005]. Notes:
[http://www.ars.usda.gov/is/AR/archive/apr05/bugs0405.htm?pf=1] This species of
mealybug, Maconellicoccus hirsutus, has spread throughout the Caribbean region since first being detected on the island of Grenada in 1994. It later spread to Mexico, Central
America, and in 2002, Florida. USDA's Animal and Plant Health Inspection Service
(APHIS) and the Florida Department of Agriculture and Consumer Services
responded together to the Florida
infestation by releasing two effective parasites (Anagyrus kamali
and Gyranusoidea indica) and a predatory ladybug (Cryptolaemus
montrouzieri) to control the mealybug, which has resulted in over 98
percent reduction in PHM population density. Despite these efforts, plants from
an infested ornamental nursery in Florida were shipped last year to 36 other U.S. states -- and PHM may have been hiding in some of
these shipments and may become established in these states. APHIS is therefore
expanding production of PHM natural enemies in preparation for release in other
states.

species (Hemiptera: Sternorrhyncha: Coccoidea). Annales de la Société
Entomologique de France 40(2): 145-168. [Foldi2005]. Notes: The matsucoccoid scale insects
inhabit the northern hemisphere, feed exclusively on Pinus spp.,
and some are very serious pests. This taxonomic revision of the Mediterranean
species supports their status as valid species, despite the wide variation of
certain morphological characters caused by environmental factors. For the genus
redescription and illustrations, Matsucoccus matsumurae Kuwana,
the type species of the genus from Japan is used. The Mediterranean species, M.
feytaudi, M. pini and M. josephi are redescribed and
illustrated. A key for their identification is provided using morphological
characters and quantitative features. In M. feytaudi, all stages
of development of both the male and female are described and illustrated.
Lectotypes of M. feytaudi and M. pini are
designated. Some information on the biology, host plants, economic importance,
natural enemies and distribution of all species is given. A world list of
extant and fossil species of Matsucoccidae is provided along with some
pertinent (host plant, feeding site, distribution) information.

stricto. (Hemiptera: Sternorrhyncha: Coccoidea). Annales de la Société
Entomologique de France 41: 81-25. [Foldi2005a]. Notes: The ground pearls comprise the
scale insect family Margarodidae s. str., and are subterranean plant sucking
parasites on roots of a wide variety of plants. Some ground pearls are serious
destructive pests of grape vines, sugar cane, oil palms, cotton or lawn grass
around the world. Both female and male development is characterised by an
apodous, feeding 2nd-instar nymph, called a cyst. The cyst is primarily
circular and often colourful, shiny, metallic or pearl-like, from which the
common name "ground pearls" is derived. Other unique features are the
strongly developed prothoracic legs for digging, the construction of a
protective test from their own liquid excreta in which the cyst is enclosed and
a behavioral adaptation by modification of their life-cycle to survive in
adverse environmental conditions. The 10 genera, currently include 105 species,
form a monophyletic group with a worldwide distribution - First-instar nymphs
and cysts are feeding instars; however, adults male and females lack mouthparts
and do not feed. Species of ground pearls reproduce either bisexually or
parthenogenetically, parthenogenesis is facultative in Eurhizococcus
brasiliensis. Females undergo three, four or five developmental stages,
while male have five. During the cyst stage, one, two or three molts may occur.
Most species have a single generation each year, although development in Margarodes
vitis requires three years including three instars of cysts. This
revision redescribes and illustrates the type species of each genus, including Margarodes
vitis (Philippi) and provides a key to the genera based on the
morphology of adult females. Lectotypes of Dimargarodes mediterraneus
(Silvestri), Heteromargarodes americanus Jakubski, Promargarodes
sinensis Silvestri and Termitococcus carratoi Silvestri
are designated. A nomenclatural change is proposed, the genus Sphaeraspis
Giard, 1894 is considered to be a synonym of Margarodes Guilding,
1829. This work also provides information on the history of the group of
Archaeococcoids; on the biology, economic importance and distribution of the
margarodids.

Suma, P., Borges da Silva, E., Blumberg, D. & Mendel, Z. 2004. Management strategies of mealybug pests of
citrus in Mediterranean countries. Phytoparasitica 32(5): 507-522.
[FrancoSuBo2004]. Notes: Six
mealybug species are reported as citrus pests in the Mediterranean basin: the
citrus mealybug Planococcus citri, the citriculus mealybug Pseudococcus
cryptus, the long-tailed mealybug Pseudococcus longispinus,
the citrophilus mealybug Pseudococcus calceolariae, the obscure
mealybug Pseudococcus viburni and the spherical mealybug Nipaecoccus
viridis. Some of these species were recently introduced in the region
and are still expanding their distribution, e.g., N. viridis.
Mealybugs are usually occasional or potential pests of citrus. However, some
species are considered key pests in certain situations. Pest
status may change with pest management systems and/or other ecological
alterations. Management strategies of mealybug populations in citrus orchards
have been generally based on biological control (mostly as classical biological
control and to a lesser extent as augmentative releases). However, chemical
controls are widely used mainly due to low adaptation of the principal natural
enemies to the climatic conditions in the Mediterranean. The application of pheromones is still restricted to
the monitoring of the citrus mealybug, whose sex pheromone is commercially
available. Mass trapping and mating disruption should be considered for use in
IPM programmes as an alternative to the supplementary chemical control.
Enhancement of biological control through the management of ant populations is
another possible control measure. The management strategies of mealybug pests
of citrus and the possible levels of integration of different tactics based on
the pest status are discussed.

I.H., O'Shea, M.G., Leonard, G.J. & Sly, L.I. 2004. Molecular investigation of the microbial
populations of the pink sugarcane mealybug, Saccharicoccus sacchari.
Annals of Microbiology 54(4): 455-470. [FrankeOSLe2004]. Notes: In an attempt to better
understand the microbial diversity and endosymbiotic microbiota of the pink
sugarcane mealybug (PSMB) Saccharicoccus sacchari Cockerell
(Homoptera: Pseudococcidae), culture-independent approaches, namely PCR, a 16S
rDNA clone library, and temperature gradient gel electrophoresis (TGGE) were
used. Previous work has indicated that the acetic acid bacteria Gluconacetobacter
sacchari, Gluconacetobacter diazotrophicus, and Gluconacetobacter
liquefaciens represent only a small proportion of the microbial
community of the PSMB. These findings were supported in this study by TGGE,
where no bands representing G. sacchari, G. diazotrophicus, and G.
liquefaciens on the acrylamide gel could be observed following
electrophoresis, and by a 16S rDNA clone library study, where no clones with
the sequence of an acetic acid bacterium were found. The dominant band in TGGE
gels found in a majority of the mealybug samples was most similar, according to
BLAST analysis, to the ß-symbiont of the craw mealybug Antonina crawii
and to "Candidatus" Tremblaya princeps, an endosymbiont
from the mealybug Paracoccus nothofagicola. Mealybugs collected
from different areas in Queensland,
Australia, were found to produce similar TGGE profiles,
although there were a few exceptions. A 16S rDNA clone library based on DNA
extracted from a mealybug collected from sugarcane in the Burdekin region in Queensland, Australia, indicated very low levels of diversity among
mealybug microbial populations.

treatment of fruits: California red scale on citrus. Journal of Economic Entomology
97(6): 1861-1867. [FuesteKoFo2004]
Notes: A process for removing or killing California red scale, Aonidiella aurantii
(Maskell), from citrus fruit as a postharvest treatment was evaluated. The
process subjects the fruit to vacuum, steam, and vacuum that physically removes
red scale from the fruit and kills those scales that are not removed from the
fruit. Different numbers of cycles and steam temperatures were compared for
efficacy in removing scale from lemons or killing those that remained. Multiple
(two to
three) cycles removed up to
96% of first moult scales on the fruit, but they were much less effective in
removing other stages, especially those that had advanced beyond the second
instar. However, it was extremely effective in killing the scales remaining on
the fruit. Although this process does not eliminate cosmetic damage caused by
scale presence, it might be used in combination with high-pressure washers
currently used in packing houses to allow importers and exporters to meet the
most stringent quarantine requirements. Because of its killing power, this
technique should be tried on other insects and commodities to see whether it
can be substituted for certain uses of methyl bromide.

is an insect that becomes economically important to agriculture when it
establishes symbiotic relationships with sap sucking insects. In sugarcane, it
is associated with Saccharicoccus sacchari and Pulvinaria
pos elongata. When infestation levels are very high, Pulvinaria,
in association with the ant, can induce severe losses in both sugar
concentration and tonnage of cane. To understand the life cycle of each
species, experiments were set up under laboratory and greenhouse conditions and
the incidence of natural enemies was determined in the field in Colombia. S. sacchari had a mean life cycle of
54.8 days, passing through two instars and the adult stage; mean progeny per
female was 219; they are gregarious and concentrate on the stem internodes. Two
species of unidentified Encyrtidae parasitized S. sacchari, with
a parasitism rate of 47%. A species of Diadiplosis (Cecidomyiidae)
eats eggs of the mature females, and a fungus identified as Aspergillus
pos parasiticus affected 53.2% of individuals in the field. Pulvinaria
sp. had a mean life cycle of 77 days and passed through two instars and the
adult. Mean progeny per female was 179; they are located on the underside of
the leaf and are not very mobile. In the greenhouse, Diadiplosis
coccidivora (Cecidomyiidae) fed on eggs of Pulvinaria sp.
females at rates up to 85%. In the field, a wasp (Encyrtidae) was found
emerging from second instar individuals of Pulvinaria sp.

drop of pest populations, these quickly recovered. The most effective control
was achieved with a combination of all three control methods, using Cryptolaemus
montrouzieri and once monthly washing with water and denaturised
alcohol in addition to chemical sprays.

effect of temperature on the development of the vedalia beetle, Rodolia
cardinalis (Mulsant) (Coleoptera: Coccinellidae), fed Icerya
purchasi Maskell (Homoptera: Margarodidae) was studied under controlled
laboratory conditions. Adults exposed to temperatures of 25, 28, 31, 34, and
37(deg)C for 72 h showed 95-100% survival, however egg production was
significantly reduced at 34 and 37(deg)C. In addition, eggs maintained at
34(deg)C showed reduced hatch and survival of larvae, and eggs held at 37(deg)C
failed to hatch. The duration of each developmental stage and survival of each
stage were measured at 10, 14, 18, 22, and 25(deg)C. There was no egg eclosion
at 10(deg)C. The developmental time from egg to adult emergence decreased from
79 to 18 days for temperatures from 14 to 25(deg)C. The sex ratio was
unaffected by these temperatures. The lower developmental temperature threshold
of R. cardinalis was estimated to be 10.8(deg)C and the
degree-day accumulation was calculated as 279 for development from egg to adult
eclosion. These results will guide further research designed to optimize
management of vedalia populations in the San Joaquin Valley of California.

[HaraJa2005]. Notes: Mealybug Maconellicoccus
hirsutus (Green) adults, nymphs, crawlers, and eggs were tested for
their susceptibility to hot water immersion at 47, 48, and 49 Degree C. Eggs
inside ovisacs were found most tolerant with prolonged survival compared with
other stages at all temperatures. Ovisacs required an average of 1.38, 1.46,
and 1.62 times longer treatment duration than adults, nymphs, and crawlers,
respectively, for 99.9% predicted mortality at 47, 48, and 49 Degree C. Lethal
time estimations were calculated from inverse predictions of regressions
derived from logit-transformed data as well as those created using a kinetic
model. LT 99.9 estimations were 47.0, 21.2, and 11.9 min at 47, 48, and 49
Degree C, respectively, by using regressions with logit transformations. The
kinetic model predictions were 43.9, 19.6, and 11.1 min at 47, 48, and 49
Degree C, respectively. During the study no emergence from eggs inside ovisacs
was found after treatments of 52, 24, and 14 min at 47, 48, and 49 Degree C,
respectively. Results from this study provide efficacious temperature-time

Fiala, B., Malsch, A.K.F., Hashim, R.B. & Maschwitz, U. 2004. Limits of protection against non-specific scale
insects (Hemiptera: Sternorrhyncha: Coccoidea) in myrmecophytic and
non-myrmecophytic species of Macaranga (Euphorbiaceae).
Entomologia Generalis 27(1): 1-13. [HeckroFiMa2004]. Notes: In Malaysia, myrmecophytic three-partner associations of several
species of Macaranga (Thouars 1806) are colonised by specific
mutualistic Coccidae living in the interior of the stem. These Coccidae are
tended by symbiotic species of the ant-genus Crematogaster (Lund 1881) and cause no damage to the plant. In addition
to these regular coccid associates, facultative infestations by epigaeic and
subterranean scale insects occur on the surface of stems, leaves, and roots.
The effects of several species of exophytic Coccoidea on M. bancana
(Muell Arg 1866) and M. hullettii (King ex Hook 1887) were
investigated. Exophytic epigaeic non-mutualistic Coccidae led to the death of
all infested M. bancana seedlings after 8 months. Myrmecophytic Macaranga
species do depend on the mutalistic ant-partners as a biotic defense against
Coccoidea. This may become disadvantageous when ant presence is reduced, e.g.
in young plants. A high degree of subterranean colonisation by ant tended
Pseudococcidae and other scale insects on Macaranga plant roots
has also been found. While myrmecophytic species are damaged by epigaeic
non-specific Coccoidea in the absence of their ant partners, root
Pseudococcidae show no detrimental effects on the trees. Associated with
various ant partners, especially with several species of the genus Pseudolasius
Emery 1887, root Pseudococcidae represent a non-protective, second
ant-Coccoidea mutualism, living facultatively next to the obligate mutualistic myrmecophytic
three-partner association.

species of Umbonichiton (Hemiptera: Sternorrhyncha: Coccoidea:
Coccidae) from New Zealand. Zootaxa 854: 1-11. [HenderHo2005]. Notes: The Coccidae of New Zealand
were revised recently and the genus Umbonichiton introduced to
include five species, four of which were described as new. This paper describes
another two new species, Umbonichiton bispinatus Henderson &
Hodgson and Umbonichiton rimu Henderson & Hodgson, both of
which are known only from the podocarp Dacrydium cupressinum. The
two species appear to be closely related. The genus Umbonichiton
is re-diagnosed and a key is presented for the separation of the adult
females.

insect species (Hemiptera: Diaspididae, Coccidae) in the urban landscape
setting. Journal of Entomological Science 39(4): 611-622. [HodgesBr2004]. Notes: Proper timing of pesticide
applications is paramount when attempting to control scale insects that are
important pests of landscape plantings. Use of degree-days and phenological
indicators can better time the applications and reduce the number of
treatments. Seasonal appearance of five species of scale insects in the urban
landscape along with flowing phenology of 40 plant species were systematically
monitored during 1997, 1998 and 2000 in Athens, GA. Scale insects discussed in
some detail are Ceroplastes ceriferus, Fiorinia theae, Melanaspis
obscura, Parthenolecanium corni, and Unaspis euonymi.
Other species for which degree-day information and limited life history data
were collected included Acanthococcus quercus, Icerya purchasi,
Pulvinaria acericola, P. floccifera, P. innumerabilis, and Toumeyella
liriodendri.

Potential of temperature, controlled atmospheres, and ozone fumigation to
control thrips and mealybugs on ornamental plants for export. Journal of
Economic Entomology 98(2): 289-298. [HollinAr2005]. Notes: Ozone (O SUB 3) fumigation is a
potential quarantine treatment alternative for controlling stored-product pests
and surface insect pests on fresh agricultural commodities. We explored the
effects of temperature, treatment time, controlled atmospheres, and vacuum in
combination with O SUB 3 to control two important pests of ornamental crops:
western flower thrips, Frankliniella occidentalis (Pergande), and
longtailed mealybug, Pseudococcus longispinus Targioni Tozzetti.
Treatment parameters tested were O SUB 3 concentrations from 0 to 3,800 ppm,
treatment durations were from 30 to 120 min, vacuums were from 0 to 0.41 bar
below ambient, temperatures were from 32.2 to 40.6 Degree C, and controlled
atmospheres were composed primarily of nitrogen, carbon dioxide, or breathing
air (BA). Treatment efficacy was enhanced by higher O SUB 3 concentration and
temperature, lower oxygen, and longer treatment times. Reduced pressure was not
an important factor. Mealybugs were more difficult to kill than thrips. A
30-min treatment of O SUB 3 at 200 ppm in 100% CO SUB 2 at 37.8 Degree C killed
47.9 and 98.0% of mealybugs and adult female thrips, respectively. All of the
ornamentals tested were damaged to some degree by O SUB 3 treatments. However,
crops with thick leaves such as orchids exhibited little damage, and the waxy
portions of certain flowers were not damaged. The results suggest that O SUB 3
has potential as a quarantine treatment to control thrips and mealybugs on
selected commodities.

wilt associated virus and mealybug wilt of pineapple. Acta Horticulturae (ISHS)
666: 209-212. [HuSeMe2005]. Notes: [IV
International Pineapple Symposium, A. Rebolledo Martinez, Ed.) The long-term
goals of our research on MWP are to understand the interactions between
viruses, vectors and host plants, and to use this information to develop
strategies to manage this important disease. Our recent work shows that
pineapple mealybug wilt associated virus (PMWaV) is a complex of
closteroviruses. We have produced specific monoclonal antibodies against two
distinct PMWaVs. A reverse transcription-polymerase chain reaction assay was
developed to detect and distinguish these two viruses. The entire genome of
PMWaV-2 was cloned and its sequence determined. The genome contains 10 open
reading frames and is typical of the monopartite closteroviruses. PMWaV-1 has
also been cloned and ten kilobases have been sequenced. The two PMWaVs are
distinct and share less than 50% nucleic acid homology with each other based on
available sequences. Both PMWaVs can be acquired and transmitted by mealybugs (Dysmicoccus
spp.). We have shown in transmission experiments that the presence of PMWaV-2
and mealybug exposure are necessary for the induction of MWP. Mealybug feeding
on pineapple plants in the absence of the PMWaVs, or the presence of the PMWaVs
in the absence of mealybug feeding, does not induce MWP symptoms. Meristem
propagation through tissue culture has been shown to produce PMWaV-free plant
material. Constructs of selected PMWaV-2 genes are being introduced into
pineapple to develop MWP-resistant transgenic plants by inducing gene-silencing
mechanisms.

Injection measures with systemic insecticides on fruit trees for leaf miner and
sucking pests management. Journal of Experimental Zoology 8(1): 221-223.
[ImtiazKhRe2005]. Notes: Injections
with systemic insecticides have been found economically cheap, environmentally
safe and comparatively effective for the control of leaf miner and sucking
pests (i.e. aphids, leaf hoppers and mealy bugs-Pseudococcidae). Different
pesticides were soaked in small pieces of sponge and placed into the tree via a
hole (1-2 cm diameter) made into the tree trunk. A maximum of two rounds of
treatment were required for sufficient control. In a single application, 8-12
ml of 40% monocrotophos, methamidophos or dimethoate was used for sucking pest
control, while 16-20 ml of the insecticides were required for sufficient leaf
miner control. Approximately 80% control of the pests were observed within a
week following the treatment.

Kaneko, S. 2004. Within-plant vertical distributions of the
scale insect Nipponaclerda biwakoensis and its five parasitoids
that exhibit frequent successful multiparasitism on the common reed.
Entomological Science 7: 331-339. [Kaneko2004].
Notes: Within-short vertical distributions of the scale insect Nipponaclerda
biwakoensis, five species of gregarious parasitoid wasps attacking the
scale, and successful multiparasitism (emergence of multiple parasitoid species
from a single host) by the parasitoids on the common reed were investigated.
Each reed shoot collected was longer than 2.0 m, and was divided into pieces of
0.5 m each from the base of the shoot. The mean number of adult female scales
per 0.5 m of shoot increased with height, but the mean rate of overall
parasitism of the female scales decreased with height. The five parasitoids
showed species-specific within shoot distribution patterns, with respect to the
rate of parasitism: Astymachus japonicus, Boucekiella depressa
and Encyrtidae sp. 2 showed the greatest rates of parasitism at heights of
0-0.5, 0.5-1.0 and 1.0-1.5 m, respectively. The parasitism rate by Aprostocetus
sp. was higher at the lower half of the shoots, whereas that by Encyrtidae sp.
1 was higher at the central positions. The distribution of the five parasitoids
largely overlapped with each other at the level of scale aggregations.
Nevertheless, successful multiparasitism occurred frequently only in several
types of species combinations that involved two parasitoid species showing
similar within-shoot distribution patterns. The rate of successful
multiparasitism by B. depressa with A. japonicus or
Aprostocetus sp. and that by Encyrtidae sp. 2 with Encyrtidae sp.
1 was constantly high at different vertical positions on the shoots. This may
be because B. depressa and Encyrtidae sp. 2 preferentially
oviposit into scales previously parasitized by these other species.

post-byzantine icons by HPLC. Journal of Liquid Chromatography & Related
Technologies 28(5): 739-749. [KarapaDaTs2005].
Notes: A high performance liquid chromatography (HPLC)
methodology, combined with UV-Vis Diode Array Detection, is developed for the
separation and identification of five reddish natural dyestuffs: cochineal,
madder, lac dye, dragon blood, and brazilwood. The method is used for the
identification of organic dyes in extracts originating from five icons, four of
which are representative for the post Byzantine era (15th to 19th century) and
one is typical for the Byzantine coloring technology (created at the 14th
century). The origin and the nature of the coloring content of Mediterranean
art objects, created in these historical periods are not well known. Carminic
acid, the main active, coloring, ingredient of cochineal was identified in four
icons, including the one of the 14th century. Brazilwood was found to be the
only organic colorant in one icon of the post Byzantine era. It was also
present, in addition to cochineal, in the icon of the Byzantine period. Further
discussion, associated with the dyestuff origin, is provided based on the
analytical results and the available historical data.

rarely bees, inside plant stems, or feed on plant roots. Here we provide the
first report of Cryptostigma from Peru. We describe Cryptostigma guadua sp.
nov. based on the adult female and the first-instar nymph. These coccids have
been collected only from the nests of Camponotus (Myrmostenus)
longipilis, Camponotus (Myrmostenus) mirabilis and Camponotus
(Pseudocolobopsis) sp. from inside live bamboos of Guadua
sp. in lowland tropical forests in Parque Nacional del Manu, in southeast Peru. The adult female and the first-instar nymph
(crawler) of Cryptostigma guadua sp. nov. are compared to closely
related species.

and new data of distribution in Central
Europe. IOBC/WPRS Bulletin
27(5): 19-24. [KozarKo2004a]. Notes:
In recent years Pseudaulacaspis pentagona (Targioni-Tozzetti,
1886) has become established in several new localities in Central Europe, however,
in some places it has been absent in recent years. Mortality was close to 100%
with great fluctuation from one part of the country to another. Mortality in
winter correlated with absolute minimum temperatures of December. The absolute
minimum below 20 Celsius caused very high mortality, however even winter this
cold did not eliminate populations from most of the infested regions. The
pheromone trap catches during the second generation reveal that this species
can reestablish high density very quickly. Density has been increasing in the Budapest area since 1991.

Notes: The developmental biology of citrus mealybug, Planococcus
citri (Risso) (Hemiptera: Pseudococcidae), was studied at constant and
varying temperatures on roses, Rosa hybrida L. Mealybug
populations were sampled daily to determine thermal constants and day-degrees
(DD) at 18.3 deg C, 26.6 d/15.5 deg C night and a fluctuating temperature
averaging 20.3 deg C. The thermal constant at 18.3 deg C was 289 DD for females
and 346 DD for males; the median number of days from egg to adult was 39 for
females and 47 ( plus or minus 1 SEM) mean days for males. At fluctuating
temperatures averaging 20.3 deg C, the thermal constant for females was 365 DD
and 421 DD for males; the median number of days from egg to adult for females
was 39, and 45 ( plus or minus 2.0 SEM) mean days for males. For females reared
at 26.6 deg C during the day and 15.5 deg C during the night, the thermal
constant was 326 DD, and the median days to egg hatch, second instar, third
instar, and adulthood were 6, 17, 26,and 32, respectively. The lower
developmental threshold was determined to be 10.9 deg C for the egg stage.
Information about development of the citrus mealybug on roses is discussed in
terms of effective pest management.

[Prediction of potential geographic distribution areas for the pine bark scale,
Matsucoccus matsumurae (Kuwana) (Homoptera: Margarodidae) in China using GARP modeling system. (In Chinese). Acta
Entomologica Sinica 48(1): 95-100. [LiHaXu2005]. Notes: The pine bark scale, Matsucoccus
matsumurae (Kuwana), is a major invasive pest of Pinus
trees. Based on the genetic algorithm for rule-set prediction modeling system
(GMS), the potential geographic distribution of the scale in China were analyzed. The results indicated that the
spreading of the scale in China under-went three main phases, i.e., sporadic
distribution phase, gradually spreading phase and rapidly spreading phase. It
was predicated that the population of the pine bark scale could be established
in 27 provinces, municipalities and autonomous regions in China, especially in the northeast and the eastern coastal
areas, and the expanding direction is upcountry in China. Further predictive analysis with Liaoning and Jilin provinces confirmed the precision of the method, and
showed that the expanding direction was consistent with that of the
countrywide, and 6 grand risk areas and 13 key areas for subsequent dispersion
were further defined for the region.

orchards in the western part of Henan province.] (In Chinese). China Fruits No. 5: 43-44. [Liu2004]. Notes: In recent years the powdery
scale (Pseudococcus comstocki) has become an important pest for
apple orchards in China. The infected trees usually reach 2.3-9.7%, but reaching 17.6%. Its
first generation nymphs usually attack the young tissues of the tree, the
second and third generation nymphs mainly attack the fruit. The bagged fruit
could be attacked by 30%. The nymphs often cause yellow, white and green marble
spots with red brown or yellow brown circles. It has three generations a year.
Its eggs hibernate in cracks in the bark or in the soil. The destructive period
for the first generation nymphs is in mid- to late May. Practice showed
spraying 1500x dilution solution of 40% Lorsban emulsion or 1500x dilution of
52.25% Nurelle-D505 emulsion in mid- to late May controls the pest.

investigations on insect pests of prickly pear cactus (Opuntia
ficus-indica (L.) Miller) in Sicily were carried out. Diaspis echinocacti
(Homoptera: Diaspididae), the common Cactus Scale, was the pest of this crop;
it can produce serious damage resulting in death and desiccation of their
hosts. It is now a cosmopolitan pest and is found in each country where Opuntia
spp. are cultivated. Recently it's becoming a problem on prickly pear and
ornamental cactus on some specialist farms in Sicily, requiring specific measures of control. This pest is
mainly located on aerial portions of the plant, especially on basal pads and
fruits. During research some natural enemies were found, among them Plagiomerus
diaspidis (Crawford) (Hymenoptera: Encyrtidae) showed higher impact on
prickly pear cactus populations. P. diaspidis is a specific
solitary internal parasite of cactus scale and it is the most effective natural
enemy in Sicily.

to semiochemicals released from a scale host, Coccus hesperidum.
Chemoecology 14(3/4): 151-156. [LoBueFoMi2004].
Notes: Metaphycus flavus is a parasitoid species
collected from the Mediterranean region which lays its eggs in the immature
stages of several economically important soft scale insects (Hemiptera:
Coccidae), including brown soft scale, C. hesperidum (host
insect). Preliminary tests suggested that the parasitoid is most successful in
producing offspring when it oviposits in the younger stages of brown soft
scale. In Y-olfactometer bioassays measuring wasp choices and residence times,
naive parasitoids were significantly more attracted to yucca leaves infested
with 26-, 27- or 28-day-old scale than to uninfested leaves, whereas leaves
with older (29- to 30-day-old) scale were no more attractive than uninfested
leaves. Parasitoids also spent significantly more time in the arm with yucca
leaves infested with 26-day-old scale than in the arm with uninfested leaves.
These results are consistent with observations of the parasitoid's reproductive
success on scale of different ages, whereby older scale are more likely to
encapsulate the developing eggs of M. flavus females than are
younger scales. Further bioassays determined that yucca leaves that had been
infested with 26-day-old scale but from which the scale had been removed were
as attractive as infested leaves. In contrast, infested yucca leaves from which
scale had been removed and the leaves subsequently washed with distilled water
were less attractive than infested leaves. Furthermore, the wash water
containing scale residues was attractive to female wasps. In total, these
results suggest that M. flavus females utilize volatile, water
soluble compounds produced by brown soft scale as cues to locate suitable
hosts.

transmission of Taro bacilliform virus. Australasian Plant Pathology 34(1):
73-76. [MacanaEbHu2005]. Notes:
Investigations were conducted into the transmission of Taro bacilliform
badnavirus (TaBV) by seed and mealybugs. Seed transmission was investigated by
artificially pollinating TaBV-infected taro. Seeds derived from four
successfully pollinated plants tested positive for TaBV by PCR. Twenty seeds
derived from each pollinated plant were also germinated; 2/80 seedlings showed
TaBV-like symptoms and tested positive for TaBV by PCR. Pollen samples taken
from TaBV-infected plants also tested positive for the virus. Mealybug
transmission was investigated by exposing 51 healthy taro plants to Pseudococcus
solomonensis that had been reared on TaBV-infected taro plants. Typical
virus symptoms developed on 17 plants between 24 and 36 days after feeding; all
these plants, in addition to 13 symptomless plants, tested positive for TaBV by
PCR. This is the first report of TaBV transmission by P. solomonensis
and the first report of P. solomonensis in Samoa.

[MackayArPa2005]. Notes: A
project to develop cultivars that are tolerant to -12 deg C was initiated in
1991 in Texas, USA, to extend the landscape use of oleanders. Seeds from
cultivars Hardy Red, Franklin D. Roosevelt and Professor Parlatorre, which are
considered to be more winter hardy, were used as parental lines. Cranberry
Cooler, Grenadine Glace and Pink Lemonade cultivars originated from Hardy Red
seeds irradiated with 45 rads. Peppermint Parfait originated from Hardy Red
control seeds (0 rad). Raspberry Sherbet was obtained from Professor Parlatorre
control seeds (0 rad), while Petite Peaches and Cream was obtained from
Professor Parlatorre seeds irradiated with 30 rad. Data are presented on the
morphological characters and field performance of each cultivars. Aphis
nerii, Aspidiotus nerii, Pseudaulacaspis cockerelli and Asterolecanium
pustulans are possible pests for these new cultivars but are more
likely in humid climates. The plants can also be attacked by Syntomeida
epilais. Recently, Homalodisca coagulata has been
identified as a vector of bacterial leaf scorch (Xylella fastidiosa)
in oleander.

Enhancement of Sphaeropsis canker of aleppo pine by the Israeli pine bast scale. Phytoparasitica
33(1): 28-32. [MadarSoKi2005]. Notes:
An interaction between the fungal pathogen Sphaeropsis sapinea
(Fr.) Dyko & Sutton, causal organism of Sphaeropsis canker,
and the Israeli pine bast scale Matsucoccus josephi (Homoptera:
Margarodidae), causal agent of pine decline, was studied, since both were
prevalent on Aleppo pine (Pinus halepensis) stands. Sphaeropsis
sapinea was isolated from larvae (stage II) and molts of the Israeli
pine bast scale collected in four Aleppo pine stands. When Aleppo pine saplings were infested with pine bast scale and
subsequently inoculated with S. sapinea most plants died, whereas
mortality of seedlings inoculated with S. sapinea alone without previous
scale infestation was negligible. Scale infestation of saplings without
subsequent fungal inoculation caused the death of one third of the plants.
Wounding of pine shoot apices by removal of needle fascicles enhanced infection
by S. sapinea. The results support the assumption that M.
josephi can play an important role in transmitting the fungal inoculum
to the host tree as well as enabling its penetration to the shoots through
wounds in the bark.

in May 2002 at the Indian Institute of Horticultural Research Farm, Bangalore, India. The coccinellid predator, Cryptolaemus
montrouzieri was released for its suppression on sapota. The population
of the mealybug declined from initial infestation of 507.6/shoot to 0.00 in 2 months
time. No other natural enemy except C. montrouzieri was observed
on R. invadens. The maximum temperature, minimum temperature,
morning relative humidity and evening relative humidity ranged from 27 to 36
deg C, 18 to 22 deg C, 52 to 91% and 30 to 76%, respectively. There was no
marked influence of these abiotic factors on the mealybug population during the
study period. The decline in the mealybug population on sapota was due to the
predatory activity of C. montrouzieri.

(Comstock) and San Jose scale, Quadraspidiotus perniciosus
(Comstock) (Homoptera: Diaspididae). Biological Control 32(3): 337-347.
[MatadhHaLa2005]. Notes:
Laboratory studies were carried out to investigate the ovipositional preference
for host species and host age, and the functional response of parasitoids of
euonymus scale, Unaspis euonymi (Comstock) and San Jose scale, Quadraspidiotus
perniciosus (Comstock) (Homoptera: Diaspididae) on San Jose scale in
temperature controlled cabinets at 25(deg)C and 16L:8D photoperiod. The
introduced parasitoids, Encarsia sp.nr. diaspidicola
(Silvestri) and Aphytis proclia (Walker) (Aphelinidae:
Hymenoptera) which have been reared continuously on San Jose scale for
augmentative release programs against euonymus scale were evaluated for host
scale preference between euonymus and San Jose scales to determine if their
rearing history had changed their host preference. Recently collected field
strains of Encarsia citrina Craw (Aphelinidae: Hymenoptera) and E.
sp. nr. diaspidicola were also evaluated for host scale preference.
Both laboratory strains of E. sp. nr. diaspidicola
and A. proclia have lost the ability to parasitize euonymus scale
and developed a preference for San Jose scale. We attribute this variation in
preference to genetic changes resulting from long term rearing of the
parasitoids on the alternate host. In contrast, the field strains of E.
citrina and E. sp. nr. diaspidicola
successfully parasitized both euonymus and San Jose scales. The host age preference for oviposition by E.
citrina, E. sp. nr. diaspidicola (lab strain) and A.
proclia was examined by exposing them to 5-45-day-old San Jose scales. E. citrina significantly
preferred 11-day-old scales, E. sp. nr. diaspidicola
(lab strain) preferred 5-9-day-old scales and A. proclia
preferred scales aged between 23 and 25 days old. To compare potential
efficiency of each species we studied the functional responses of females
exposed to 4, 8, 16, 32, 64 or 128 scales for 24 h. E. citrina
exhibited a type I response and E. sp. nr. diaspidicola
(lab strain) and A. proclia exhibited type II responses to host
density. E. sp. nr. diaspidicola (lab strain)
attacked greater number of scales per day compared to E. citrina
and A. proclia.|

the parasitism rates of introduced parasitoids on host, the arrowhead scale (Unaspis
yanonensis) in stable host-parasitoids system. Journal of Applied
Entomology 128(4): 267-272. [MatsumItNi2004b].
Notes: In 1980, two species of parasitoid wasps Aphytis
yanonensis DeBach et Rosen and Coccobius fulvus Compere
et Annecke) were introduced to Japan from China as biological control agents to combat the arrowhead
scale (Unaspis yanonensis Kuwana). These introductions represent
one of the most successful projects in the history of biological control in Japan. To examine whether density dependent parasitism was
inevitable for success of biological control, we tried to detect temporal and
spatial density dependence in parasitism rates using time-series data of scale
density, as well as parasitism, over a 16-year period. The work was conducted
in a Satsuma mandarin orange (Citrus unshiu Marc.)
orchard in which we previously demonstrated that the system appeared to have
stabilized after a decline in scale density following the introduction of the
parasitoids. Earlier work also indicated that C. fulvus
contributes most to the reduction in, and the stability of, scale density. In
this study, we examined: (1) the relationship, on a whole-orchard basis,
between scale density and the rates of parasitism by A. yanonensis, C.
fulvus, and a combination of the two species; (2) whether parasitism
was positively correlated to scale density on a single-tree basis among
generations and (3) whether spatial density dependence was detectable within
generations on an individual-tree basis. Parasitism by A. yanonensis
was temporally density-dependent on scale population density at the
whole-orchard level, while parasitism by C. fulvus was not.
Parasitism by A. yanonensis or by C. fulvus was
rarely positively correlated to scale density at the single-tree level, and
spatial density-dependence was hardly detected at all at this level. Most
analyses of combined parasitism rates were similar to rates of parasitism by C.
fulvus alone. Contrary to conventional wisdom of biological control
theory, this study demonstrates that density dependence is not necessarily
detected, even in a system in which a natural enemy has long held pest density
stable at low levels.

2005. The triple alliance: how a plant-ant, living in an ant-plant, acquires
the third partner, a scale insect. Insectes Sociaux 52(2): 169-176.
[MoogSaHa2005]. Notes:
Mutualistic associations between ants and plants often involve a third partner,
scale insects (Hemiptera, Coccoidea). In southeast Asia, plant-ants of the
genus Cladomyrma live together with coccoids in hollowed twigs of
a wide range of ant-plants (myrmecophytes). Established colonies never lack
sap-sucking scale insects and the ants appear to be dependent on the honeydew
excretions of their trophobionts. Acquisition of scale insects thus seems to be
an important step in the successful establishment of a new colony on a host
plant. Coccoids may either be transported by a foundress ant on her nuptial
flight (vertical transmission via co-dispersal) or ant and coccoid disperse on
their own and associate anew during colony initiation (horizontal
transmission). Here we test the assumption that founding gynes of Cladomyrma
do not transport scale insects during their dispersal flight, and we determine
when and how trophobionts are acquired. The results obtained in this study show
that although coccoids are not carried by foundresses, their numbers within
founding chambers of Cladomyrma increased with the founding
stage. In all Cladomyrma species, colony-founding is claustral
and the entrance hole into the nest chamber is first plugged with pith debris
and later grows over by wound callus. However, access of trophobionts into
hollow twigs is facilitated either by additional small openings ('secondary
slits') produced by the foundress ant after hollowing out a nest chamber or by
the maintenance of an orifice at the entrance hole during the founding period.
Immature pseudococcids experimentally placed onto twigs close to a Cladomyrma
foundation readily entered these slits. Exclusion experiments suggest that
foundresses of C. petalae are less successful in rearing their
first offspring if entry of coccoids into founding chambers is prevented.

paper briefly discusses the principle of augmentation and describes the current
status of augmentative biological control of citrus pests such as Aonidiella
aurantii and Planococcus citri in South Africa. Only natural enemies which are currently available
to growers are discussed in this article, i.e. the parasitoids Coccidoxenoides
perminutus, Trichogrammatoidea cryptophlebiae and Aphytis
lingnanensis and the predator Cryptolaemus montrouzieri.

A.K. 2005. Study on the biology of
the mealybug, Ferrisicoccus psidii. Annals of Plant Protection
Sciences 13(1): 239-240. [Mukhop2005]. Notes:
A new mealybug was observed infesting guava in Coimbatore, Tamil Nadu, India. The pest was identified as Ferrisicoccus
psidii. Daily observations were made on the ecdysis of nymphs, waxy
secretions, sex ratio, preoviposition and oviposition period, fecundity and
incubation period of eggs. The crawlers, sexes of which were indistinguishable
at that stage completed their moulting at the age of 4-11 days, being 72.0% at
7-9 days. The second and third instar female nymphs completed their moulting at
the age of 10-24 (15.5 plus or minus 2.80) and 17-29 (21.35 plus or minus 2.60)
days, being 66.8 and 60.0% at the age of 13-17 and 19-22 days, respectively.
The second, third and fourth instars of male moulted at the age of 10-20 (13.28
plus or minus 2.02), 11-19 (14.71 plus or minus 2.0) and 15-23 (18.69 plus or
minus 1.80) days, being 69.4, 62.4 and 68.5% at the age of 11-14, 13-16 and
17-20 days, respectively. The colour of the crawlers and last 3 instars of
female were rosy, creamy pink, pinkish chocolate and chocolate; waxy dusts are
found on their dorsum, quantity being progressively increased with the progress
of development and stage. The last 3 instars of female secreted 7-8 pairs and
13 pairs of marginal waxy tassels, mostly abdominal. All the instars of female
and the second instar of male secreted a tubular waxy anal process. The normal
preoviposition and oviposition period and fecundity of the species are also
discussed. This is thought to be the first record of F. psidii in
the Indian subcontinent.

Nassar, N.M.A. 2004. Cassava: some considerations on its ecology and
improvement. Journal of Food, Agriculture & Environment 2(3/4): 167-173.
[Nassar2004]. Notes: Cassava is
the principal food for poor people in the tropics. India leads the world by productivity of 26 t/ha. Cassava
reproduces by cuttings which accumulates pathogens. Apomixis represents an
alternation to avoid this contamination. Apomixis was discovered in the wild
cassava and transferred successfully to the cultivated one. Wild cassava
relatives offered sources for its improvement for tolerance to bacteria blight
and mosaic. More than 2 million hectares in Nigeria are now planted by cultivars from cassava hybrids
with Manihot glaziovii. The species is potentially used for
breeding cultivars tolerant to mealy bug and offers the safest way to control
this pest if the artificial ecosystem of biological control has broken down.
Cassava diversity in unmanaged ecosystems is highly affected by both the
environment and human pressures.

Nweke, F. 2004. New challenges in the cassava transformation in
Nigeria and Ghana. EPTD Discussion Paper -- Environment and Production
Technology Division, International Food Policy Research Institute 118.
[Nweke2004]. Notes: The cassava
transformation involves a shift from production as a low-yielding,
famine-reserve crop to a high-yielding cash crop increasingly prepared and
consumed as gari. This paper documents the four key factors that are driving
the cassava transformation in Nigeria and Ghana. First, the IITA's new high-yielding Tropical Manioc
Selection (TMS) varieties boosted cassava yield by 40% without fertilizer
application. Second, high consumer demand for cassava by rural and urban
households fuelled the producer incentive to plant more land with cassava.
Third, the use of the mechanical grater to prepare gari released labour,
especially female labour, from processing for planting more cassava. Fourth,
the Africa-wide biological control programme averted the devastating cassava
mealybug epidemic (Phenacoccus manihoti). Challenges to enhancing
the value of cassava as a powerful poverty-alleviating crop in Africa
are identified.

distribution of California red scale, Aonidiella aurantii
(Maskell), on orange trees.] Distribuzione spaziale di Aonidiella
aurantii (Maskell) su piante di arancio. (In Italian; Summary In
English). Informatore Fitopatologia 54(11): 54-58. [OrtuCo2004]. Notes: Specific surveys on within-tree
spatial distribution of California
red scale, Aonidiella aurantii, on orange trees were conducted in
2002-03 in Italy, to determine the most infested parts of canopy from
where the insect spreads throughout the tree. The following plant organs were
sampled: fruits, leaves, green twigs and 3- to 4-year-old branches from each canopy
quadrant (north, east, south, west). Population density of each sample was
determined using a microscope. The results were analysed using analysis of
variance. Population distribution did not differ significantly among the four
quadrants of the canopy. The highest population density occurred on twigs,
followed by fruits and then by leaves. The highest insect density observed
during the first generation, on 2- to 3-year-old twigs, indicated a slow
movement of California red scale from lignified to green twigs. Therefore,
pruning the heavily infested twigs allows to reduce the centres of infestation
of A. aurantii population, to create unfavourable microclimatic
conditions for population development and to reduce population density using
low environmental-impact insecticides.

products were evaluated against nymphs I, nymphs II, and mature females of the
wild cochineal Dactylopius opuntiae (Cockerell) under laboratory
conditions: a domestic detergent (Roma(R)) and a new unclassified product (Peak
Plus, in registration). Each was sprayed on directly infested prickly pear
cladodes. Concentrations tested for both products were 0.5, 1.0, 1.5, 2.0, 2.5,
3.0 and 6.0%. Replicated applications of the same concentrations, also were
evaluated from 0.5 to 3.0% over the same development stages. Higher
susceptibility of nymphs I was observed, showing mortality of nearly 50% with
6% Roma(R), while nymphs II and mature females were more susceptible to Peak
Plus, achieving approximately 50% control with concentrations of 1.5 and 3.0%,
respectively. In repeated applications, the highest mortality was observed in
mature females for both products.

The current presence and activity of yellow scale (Aonidiella citrina)
in citrus trees in Italy were investigated during 1999-2001 in Calabria and Sicily. Pheromone traps were used to assess pest population
composition and the composition of useful entomofauna. Aonidiella citrina
was limited in the area where it was first sighted 10 years ago. Three insect
generations were completed and overwintering was observed at different
developmental stages (mainly during the second instar stage). Three intense
flight periods were observed (April, July and September), each formed by 2
cohorts. The most active predators were Aphytis melinus and Encarsia
citrina.

Effects of food colorants on photooxidation of lipids added to Alaska pollack Theragra chalcogramma surimi.
Fisheries Science 71(2): 397-404. [PanUsOh2005]. Notes: Food colorants including rose
bengal, erythrosine B, phloxine B and cochineal extracts were added to Alaska pollack Theragra chalcogramma surimi
which was previously added with methyl linoleate (MeLe) or ethyl
eicosapentaenoate (EPA Et). All the surimi were exposed to a 100-watt light
tungsten bulb (4500 lux) in a cold room at 5 deg C. Four isomeric
hydroperoxides, including 13-cis,trans-, 13-trans,trans-, 9-trans,cis- and
9-trans,trans-MeLe hydroperoxides, were generated by oxidation of MeLe added to
surimi with and without cochineal extracts after exposure to light for several
hours. For the surimi containing rose bengal, erythrosine B and phloxine B,
extracted lipids contained not only the above four hydroperoxide isomers but
also 12-cis,trans- as well as 10-trans,cis-MeLe hydroperoxides. EPA Et added to
surimi which contained rose bengal, erythrosine B and phloxine B generated
characteristic isomeric hydroperoxides, including 6-cis,trans- and
17-cis,trans-EPA Et hydroperoxides due to 1O2 mediated oxidation. The
pro-oxidative potentials of four food colorants in surimi against added EPA Et
or MeLe increased as the order of cochineal extracts < phloxine B <
erythrosine B < rose bengal. These results clearly demonstrated that the
addition of certain food colorants to surimi accelerated 1O2 mediated lipid
oxidation to result in the generation of characteristic hydroperoxide isomers.
