Surveys
to assess the amount of pesticide in wool and the use of pesticides
by woolgrowers in Queensland.
Ward MP, Armstrong RT.
Queensland Department of Primary Industries, Animal Research
Institute, Locked Mail Bag 4, Moorooka, Queensland 4105.
OBJECTIVE: To measure the amounts of pesticide
residue in wool grown in Queensland between 1997 and 1999, and
to describe the use of pesticides for the control of lice infestations
and blowfly strike in Queensland sheep flocks.
DESIGN: Pesticide residues were measured in a random sample
of wool from Queensland clips offered for sale during 1998 and
1999. Information on pesticide use was obtained from a trace-back
postal survey.
PROCEDURE: Samples taken from wool lots were tested for the
presence and amount of organophosphorus (OP), synthetic pyrethroid
(SP) and insect growth regulator pesticides. A questionnaire
seeking information on flock characteristics and pesticide use
was sent to the manager of each flock from which a wool sample
was tested.
RESULTS: The mean amount of OP and SP residue was 2.0 and 0.8
mg/kg, respectively. Ninety-five and 98% of wool samples contained
< 9 mg/kg and 7 mg/kg of OP and SP residues, respectively.
The mean amount of cyromazine, diflubenzuron and triflumuron
was 12.7, 5.8 and 13.0 mg/kg, respectively.
The amounts of OP, cyromazine and triflumuron
residues were greater in wool from
flocks located in southern Queensland.
CONCLUSION: Most (95%; 95% CI, 92-97%) Queensland wool clips
grown between 1997 and 1999 meet the suggested Australian maximum
acceptable residue amounts for OP and SP pesticides.

Malaria
is one of the main parasitic diseases in south of Iran. Anopheles
stephensi is known to be the main malaria vector in this area.
The natural breeding places of this vector were different. Many
of them had running water and other had standing water. The
larvicidil activity of a new chitin synthesis inhibitor Crriflumnron,
SC 48%) was studied in the laboratory and field conditions.
In the laboratory studies, the efficacy of triflomuron on the
third instar larvae of Anopheles stephensi was determined. These
larvae were treated with triflumuron on diferent exposure times
(0.5 ,1 ,2, 4, 6, 8, 12, 16, 24, 48 hour, and continued exposure
time). The results indicated that with the increase of the exposure
time, the mortality will gradually increase to about 75% up
to the 24 hour and to about 90% up to the continued exposure
times. The results revealed that larvicide would be present
at a desired concentration (about 0.0008 mg/l) in the larval
breeding place. Triflumuron was applied at 48 , 72 , 96 and
120 gr a.i/ha dosages. Triflumuron was effective on the larvae
of anopheline mosqunes in the natural breeding place with standing
water at 96 and 120 gr a.i/ha dosages. In the natural breeding
place with running water, triflumuron was not effective at any
dosages.

Dissipation of residues of benzoylurea insecticides
teflubenzuron (TFB) and triflumuron (TFM)
under field conditions was evaluated on a pear orchard in Greece.
Residues were determined by UV-HPLC analysis, with a detection
limit of 0.030 mg/kg for both pesticides. TFB residues in pears
were found to persist for 2 weeks and
decline thereafter with 48% of the initial deposit remaining
42 days after the last application. TFM residues were found
to decline following first-order kinetics and with a half-life
of 39(+/-7) days. Residues of both pesticides found in
pears collected at harvest maturity were lower than the maximum
residue limits (MRLs) set by individual countries. Dissipation
of TFB and TFM in cold-stored pears
was also evaluated. TFB residues were very persistent for the
whole storage period, whereas TFM residues
did not dissipate for 6 weeks and then showed a constant decline;
7% of the initial concentration remained at the end of the storage
period of 29 weeks.

High-performance
liquid chromatographic determination of benzoylurea insecticides
residues in grapes and wine using liquid and solid-phase extraction.
Miliadis GE, Tsiropoulos NG,
Aplada-Sarlis PG.
Benaki Phytopathological Institute, Kifissia,
Greece.
A method for the determination of the benzoylurea
insecticides diflubenzuron, triflumuron,
teflubenzuron, lufenuron and flufenoxuron in grapes and wine
by HPLC has been developed and validated. Grape samples (50
g) were homogenized and extracted with ethyl acetate-sodium
sulfate and further cleaned-up by solid-phase extraction on
silica sorbent. Wine samples (10 ml) diluted with water (1:3)
were solid-phase extracted on an octadecyl sorbent using methanol
as the eluent. The pesticides were separated on a reversed-phase
octadecyl narrow-bore column by gradient elution and the residues
were determined with a UV diode array detector. The calibration
plots were linear over the range 0.05-5 micrograms/ml. Recoveries
of benzoylurea pesticides from spiked grapes (0.02-2.0 mg/kg)
and wine (0.01-0.2 mg/l) were 85.8-101.6% and 69.1-104.8%, respectively,
and the limits of quantification for these insecticides were
< 0.01 mg/kg for grapes and < 0.01 mg/l for wine. The
method was applied to the determination of flufenoxuron and
teflubenzuron residues in grapes from treated fields and in
produced wine.

Laboratory of Parasitology, Veterinary
School of Lyon, Marcy L'Etoile, France.
The current importance of Dermanyssus gallinae, mainly in egg
layer, in Europe is pointed out. The limits of conventional
control methods are underlined (development of mite resistance--future
insecticide legislation and animal welfare legislation). Alternative
control methods such as feeding deterrents or biological control,
are reviewed in the context of poultry pest management.

Suppression
of the blowfly Lucilia sericata using odour-baited triflumuron-impregnated
targets.
Smith KE, Wall R.
School of Biological Sciences, University of
Bristol, U.K.
Field trials were carried out in 1995 and 1996
on farms in the south-west of England to assess the extent to
which odour-baited targets could be used to suppress populations
of the ectoparasitic blowfly, Lucilia sericata, in sheep pastures.
Targets were constructed from 41 x 41 cm squares of aluminium
sheet, covered by white cloth which had been dipped in a mixture
of sucrose solution (50% w/v) and the chitin synthesis inhibitor
triflumuron (10% suspension concentrate).
Each target was baited with approximately 300 g of liver and
sodium sulphide solution (10%). Three matched sheep farms were
used in the trials. In 1995, triflumuron-impregnated
targets were placed around the periphery of sheep pastures at
one of the farms in late June, at approximately one target per
hectare. In 1996, triflumuron-impregnated
targets were placed around the periphery of sheep pastures of
a second of the farms in early May, at approximately five targets
per hectare. Each year, five sticky targets, used to monitor
the L. sericata populations, were also placed in fields at the
experimental and the other two farms, which acted as controls.
In 1995, the results provided some, although inconclusive, evidence
that the triflumuron-impregnated
targets had reduced the numbers of L. sericata relative to the
populations on the two control farms. In 1996, however, the
density of L. sericata on the experimental farm was reduced
to almost zero and remained significantly lower than on two
control farms throughout the period during which the triflumuron-impregnated
targets remained in the field. The results are discussed in
relation to the use of triflumuron-treated
targets as a practical means of controlling L. sericata and
sheep blowfly strike.

Fluorinated
organics in the biosphere.
KEY BD, HOWELL RD, CRIDDLE CS
Dep. Civil
Environ. Eng., Mich. State Univ., East Lansing, MI 48824, USA.
BIOSIS COPYRIGHT: BIOL ABS. The use of organofluorine compounds
has increased throughout this century, and they are now ubiquitous
environmental contaminants. Although generally viewed as recalcitrant
because of their lack of chemical reactivity, many
fluorinated organics are biologically active. Several
questions surround their distribution, fate, and effects. Of
particular interest is the fate of perfluoroalkyl substituents,
such as the trifluoromethyl group. Most evidence to date suggest
that such groups resist defluorination, yet they can confer
significant biological activity. Certain volatile fluorinated
compounds can be oxidized in the troposphere yielding nonvolatile
compounds, such as trifluoroacetic acid. In addition, certain
nonvolatile fluorinated compounds can be transformed in the
biosphere to volatile compounds. Research is needed to assess
the fate and effects of nonvolatile fluorinated organics, the
fluorinated impurities present in commercial formulations, and
the transformation

[Small-scale
evaluation of the efficacy of growth-regulating insecticides
on larvae of the Simulium damnosum complex (Diptera: Simuliidae)]
[Article in French]
Doannio JM, Dossou-Yovo J, Duval
J, Hougard JM.
Institut Pierre Richet/O.C.C.G.E., Bouake, Cote
d'Ivoire.
The efficacy of insect growth regulators was
assessed in small scale tests on larvae of the Simulium damnosum
complex (Diptera: Simuliidae) in the Ivory
Coast. Three compounds [OMS
2015 (triflumuron), OMS
3009 (teflubenzuron), OMS
3013 (chlorfluazuron)] belong to the group of benzoylphenyl-urea
substitutes; these IGR's are supposed to inhibit chitin synthesis.
Two other compounds are Juvenile Hormone Analogs (JHA's) (OMS
3007 and OMS 3019). The last compound (OMS 3010) is a phenoxycarbamate.
The first three compounds had a low efficacy on blackfly larvae,
which is consistent with the literature data for another compound
of this group: diflubenzuron. The other three compounds (OMS
3007, OMS 3010 and OMS 3019) were much more efficient, OMS 3010
and OMS 3019 showing high activity at low concentrations. These
results would justify further studies on the effect of larval
age and exposure parameters, and eventually full scale river
tests.

Ovicidal activity was observed in four adult
groups (virgin males; virgin females; newly gravid females;
and inseminated, reproducing females) of the German cockroach,
Blattella germanica (L.), fed the chitin synthesis inhibitors
triflumuron, chlorfluazuron, hexafluron,
and UC 84572 (structure not disclosed) at the LC50's and LC95's
determined from fifth-stage nymphs. All compounds were active
only when fed to reproducing females (including the feeding
period in which the ootheca is developing). Hexafluron
and triflumuron at the LC50 caused 100% inhibition of hatch
in reproducing females. Chlorfluazuron and UC 84572 at
the LC50 had similar ovicidal activity (45.8 and 50.0% hatch,
respectively). Female German cockroaches fed the chitin synthesis
inhibitors before mating and after the ootheca had protruded
from the abdomen were not affected. Reproductive capabilities
of males were not affected, and males did not effectively transfer
the compounds to untreated females during mating.

Effects
of five insect growth regulators on laboratory populations of
the North American house-dust mite, Dermatophagoides farinae.

The potential of insect growth regulators
(methoprene, hydroprene, fenoxycarb, diflubenzuron and triflumuron)
to control populations of the North American house-dust mite
Dermatophagoides farinae (Hughes) was assessed in laboratory
bioassays. Methoprene was most effective at suppressing population
growth, especially at concentrations of 1.0% (10,000 ppm) and
5.0% (5000 ppm) active ingredient. Hydroprene, structurally
related to methoprene, also suppressed house-dust mite populations
but not as consistently as methoprene. Fenoxycarb may be effective
at controlling house-dust mites but at greater concentrations
than were tested. Diflubenzuron and triflumuron,
two chitin-synthesis inhibitors, failed to suppress mite numbers
and may, in fact, stimulate reproduction in some cases. Almost
all concentration of the insect growth regulators were shown
to be ineffective when assayed 90 days after treatment.

Efficacy
of chitin synthesis inhibitors on nymphal German cockroaches
(Dictyoptera: Blattellidae).
DeMark JJ, Bennett GW.
Second- and fifth-instar Blattella germanica
(L.), fed the chitin synthesis inhibitors
triflumuron, chlorfluazuron, hexafluron, and UC 84572
(structure not disclosed) were examined for mortality and developmental
abnormalities. All compounds were active against B. germanica
(L.), with lower diet concentrations being required to kill
second instars compared with fifth instars. Chlorfluazuron was
significantly more active against second and fifth instars (LC50
= 0.000191 and 0.000363% AI, respectively for the second and
fifth instars). UC 84572 also killed nymphs at extremely low
concentrations (LC50 = 0.000508 and 0.000754% AI, respectively,
for second and fifth instars). LC50's
for hexafluron and triflumuron against fifth instars were more
than 1,000 times higher than that for chlorfluazuron.
Sensitive periods of exposure were determined by comparing effects
when four different age classes of fifth instars (1-, 4-, 7-,
and 10-d old) fed on the compounds for 3 d. Triflumuron
was most effective when ingested during the first three age
classes and hexafluron was most effective during the last three
age classes. Chlorfluazuron and UC 84572 were most effective
when ingested during the second age class (days 4-6).
Adults surviving exposure during the fifth instar were often
deformed and weak; they died at a greater rate than the controls.
However, most surviving adults were able to reproduce normally.

Effects
of chitin synthesis inhibitors on incorporation of nucleosides
into DNA and RNA in a cell line from Manduca sexta (L).
Klitschka GE, Mayer RT, Droleskey
RE, Norman JO, Chen AC.
Five putative chitin synthesis inhibitors (CSI)
were tested to determine if they inhibited nucleoside incorporation
into acid precipitable material in a cell line from Manduca
sexta (L.). The results varied. Diflubenzuron (DFB) (100 micron)
inhibited cytidine incorporation by 38%; EL-494 (100 micron)
inhibited adenosine incorporation by 43%; Bay Sir 8514 (100
micron) inhibited uridine incorporation by 24%. Superdiflubenzuron
(100 micron) was the worst inhibitor overall (18-22%) for the
benzoylphenyl urea CSI. The triazine CSI, CGA 19255, was the
best inhibitor tested with 60% inhibition for cytidine and 49%
for adenosine incorporation into DNA and RNA. Examination of
cells incubated with diflubenzuron by scanning electron microscopy
revealed distinct external morphological changes. Transmission
electron microscopy showed that crystalline structures accumulated
in the cytoplasm of cells treated with DFB. The crystalline
structures were assumed to be diflubenzuron and they persisted
even after diflubenzuron was removed from the medium.

Feeding
BAY Vi 7533 to hens.
Miller RW, Wong Y, Thomas OP.
BAY Vi7533 (2-chloro-N-[[[4-(trifluoromethoxy)phenyl]
amino] carbonyl] benzamide) was fed to White Leghorn and Vedette
Mini-broiler breeder hens at concentrations ranging from 0 to
25 ppm in the ration. Concentrations of 15 and 25 ppm resulted
in greater than 95% mortality of house flies, Musca domestica
L., seeded as larvae into the droppings. Concentration of 25
ppm reduced egg production in the White Leghorn but not in the
Vedette Mini-broiler hens. At each concentration
(except 5 ppm for Vedette Mini-broilers) residues of the compound
were detected in the eggs. These residues, however, had
no adverse effects on fertility or hatchability of the eggs.
