Dieldrin and Diazinon Resistance in Populations of the Australian Sheep Blowfly, Lucilia cuprina, from Sheep-grazing Areas and Rubbish Tips

Diazinon resistance, fluctuating asymmetry and fitness in the Australian sheep blowfly, lucilia cuprina.

Genetic evidence suggests that the evolution of resistance to the insecticide diazinon in Lucilia cuprina initially produced an increase in asymmetry. At that time resistant flies were presumed to be at a selective disadvantage in the absence of diazinon. Subsequent evolution in natural populations selected modifiers to ameliorate these effects. The fitness and fluctuating asymmetry levels of r...

Environmental and genetic effects on the asymmetry phenotype: Diazinon resistance in the Australian sheep blowfly, Lucilia cuprina.

The asymmetry phenotype of diazinon-resistant flies lacking a fitness/asymmetry Modifier (+/+; R/-) was dominant and independent of developmental temperature, larval density and diazinon concentration. Asymmetry score, pooled over three bristle characters, was approximately 50% greater for these phenotypes than for those of modified genotypes (M/+; +/+) and unmodified susceptibles (+/+; S/S) re...

The biology and ecology of the Australian sheep blowfly, Lucilia cuprina (Wiedemann) – an update

Cuticular lipids of adults and puparia of the Australian sheep blowfly Lucilia cuprina (Wied.).

The presence of a strong contact component in the sex and ovipositing behavior of the sheep blowfly Lucilia cuprina Wied. prompted an investigation into the chemical composition of the cuticular wax of the adult male and female flies as well as that of the blowfly puparia. Thin-layer chromatography indicated that the lipids in all the waxes examined comprise hydrocarbons, nonglyceryl esters, tr...

Estimating population densities of the Australian sheep blowfly Lucilia cuprina (Wiedemann) (Diptera: Calliphoridae) from catches in wind-oriented traps

An analysis of 2-hourly catches of the blowfly, Lucilia cuprina, in 10 wind-oriented fly traps on 34 trapping days (06.00 – 18.00h) during the period November 1984 – May 1985 indicated that air temperature was the principal factor regulating the number of insects caught. Small but significant effects were associated with radiation, time of day and relative humidity; effects due to wind were not...
