“…Percentage egg hatch is plotted against target age (days), where target age is the length of time following initial treatment prior to bioassay. 47% (Howard & Wall, 1996a). Furthermore, only 6% of eclosed larvae pupariated; longer exposure times prevented any pupariation.…”

“…This is because a number of the exposed males would be able to disrupt the fertility of unexposed females, assuming exposed males are equally competitive and as long lived as unexposed males (Langley & Weidhaas, 1986;Wall & Howard, 1994;Wall, 1995). Previous studies have shown that after contact with materials impregnated with insect growth regulators, such as triflumuron or pyriproxyfen, male flies can disrupt the reproduction of unexposed virgin females (Langley et al, 1988;Howard & Wall, 1996a). This may be the result of direct effects through impairment of spermatogenesis or insemination ability.…”

“…This may be the result of direct effects through impairment of spermatogenesis or insemination ability. Alternatively exposed males may simply pick up sufficient active ingredient on their bodies to be able to pass on effective doses to unexposed females during mating (Masner et al, 1968;Howard & Wall, 1996a).…”

“…It causes transovarial ovicidal and larvicidal effects in both the face fly, Musca autumnalis and the house fly, Musca domestica following ingestion or topical/tarsal contact by female adults (Knapp & Herald, 1982Knapp & Cilek, 1988;Howard & Wall, 1995a,b). Furthermore, after contact with targets impregnated with triflumuron, male M. domestica can impair the reproductive output of unexposed virgin females (Langley et al, 1988;Howard & Wall, 1996a). This may be the result of direct effects on males, through impairment of spermatogenesis or insemination ability or, alternatively, exposed males may simply pick up sufficient active ingredient on their bodies to be able to pass on effective doses to unexposed females during mating (Howard & Wall, 1996a).…”

Effects of targets impregnated with the chitin synthesis inhibitor triflumuron on the blowfly Lucilia sericata

The effects of exposure of adults of the blowfly Lucilia sericata (Meigen) for 24 h to cloth targets impregnated with the chitin synthesis inhibitor triflumuron plus sucrose or sucrose only, were considered. When both male and female L. sericata were exposed to targets treated with sucrose only, the percentage egg hatch varied between 60–75%. When both sexes were exposed to targets treated with 10% triflumuron plus sucrose the percentage egg hatch varied between 3–7%. When females alone were exposed to triflumuron, prior to the introduction of unexposed males, egg hatch varied between 4–14%. The exposure of males alone to 10% triflumuron treated targets, prior to the introduction of unexposed virgin females, did not give any consistent significant decrease in the mean percentage egg hatch. However, repetition of this trial with males exposed to targets treated with 15 or 20% triflumuron, resulted in a percentage egg hatch of 3.1% and 10.3%, respectively. These results suggest that at relatively high target concentrations, males can transfer effective doses of triflumuron to unexposed virgin females. The exposure of adults to triflumuron treated targets did not significantly increase the mortality of either male or female L. sericata. Furthermore, bioassays showed that there was no significant decline in the ovicidal effectiveness of targets treated with 10% triflumuron and sucrose solution following exposure to sun and rain for up to 8 weeks in 1995 and 1996. The results suggest that targets treated with triflumuron suspension concentrate and sucrose may form the basis of an effective system for the control of L. sericata in the field. However, the relatively high concentrations of triflumuron required and the low efficiency with which males are able to transfer effective doses to unexposed females may diminish one of the main theoretical advantages of using a chitin synthesis inhibitor, such as triflumuron, over a conventional insecticide.

Lufenuron, a chitin-synthesis inhibitor, interrupts development ofDrosophila melanogaster

The chitin‐synthesis inhibitor lufenuron was administered to Drosophila melanogaster to better understand the effects of chitin‐synthesis interruption during the development and reproduction of this insect. When larvae were fed a diet containing a low concentration (<1 ppm) of lufenuron, mortality was observed during either larval or pupal development, depending on the dose. Survivor adults were unable to fly, probably due to abnormal cuticular development in the wing hinge regions of the thorax. Larvae fed a higher concentration (10 ppm) completed development within that instar, but died during ecdysis to the next instar, presumably due to inadequate cuticle synthesis. Third instar larvae pupariated, but the puparium was abnormal, and pupation did not occur. Adults fed 10 ppm showed normal viability but slightly depressed oogenesis; additionally, although their eggs were fertilized, they failed to hatch. Examination of the embryos showed that they completed development but were unable to perforate the surrounding vitelline membrane, probably due to a weakened chitinous mouth hook assembly that was insufficiently rigid to effect hatching. These results identify stages during D. melanogaster development when chitin synthesis and deposition are critical. This information will be useful for identifying chitin‐synthesis mutants of this insect. J. Exp. Zool. 278:37–44, 1997. © 1997 Wiley‐Liss, Inc.

Autosterilizing devices, composed of 20X50 cm rectangles of white polyester cloth, baited with 50% w/v sucrose and impregnated with 10% suspension concentrate of the chitin synthesis inhibitor triflumuron, were suspended in two caged-layer poultry houses on a 6 ha farm near Bhubaneswar, Orissa Province, in north-east India. Populations of Musca domestica Linnaeus declined significantly over 6 weeks in houses in which the triflumuron-treated targets had been deployed. Following the removal of the targets from these houses, the M. domestica populations subsequently increased. No comparable changes were observed in a control poultry house in which an equal number of targets, dosed with 50% w/v sucrose only, were suspended. Laboratory evaluation of the sugar-baited triflumuron targets confirmed that exposure of the strain of M. domestica present in the poultry manure to triflumuron-treated targets reduced egg hatch to less than 1%. There was no decline in the quantity of triflumuron present on targets during their 6 week exposure in the poultry houses, as shown by gas chromatography. Furthermore, a laboratory bioassay demonstrated no decrease in the potency of the chemical over the exposure period. However, the quantity of sugar present on targets decreased significantly after only 3 weeks exposure. However, populations in the treatment houses were not eliminated and immigration from surrounding houses may have reduced the effectiveness of the technique. The results are discussed in relation to the use triflumuron-treated targets as a practical autosterilizing system for house fly control in livestock production systems.
