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...
متن کاملPolygenic and single gene responses to selection for resistance to diazinon in Lucilia cuprina.
Following mutagenesis with ethyl methanesulfonate, selection in a susceptible strain with a concentration of the insecticide diazinon (0.0004%, w/v) above that required to kill 100% of the susceptible strain, the LC100 of that strain, resulted in a single gene response. The resultant four mutant resistant strains have equivalent physiological, genetical and biochemical profiles to a diazinon-re...
متن کاملEnvironmental 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...
متن کاملGenetic control of Lucilia cuprina
The Lucilia cuprina genetic control program conducted by members of CSIRO Entomology is reviewed. A strategy for reviving interest in area-wide control of this pest is suggested through the development of mass-rearing abilities, leading to the application of SIRM to eradicate the pest from Tasmania. Genetic control methods could be integrated in the SIRM program if appropriate strains could be ...
متن کاملSpecies, sub-species and hybrid populations of the blowflies Lucilia cuprina and Lucilia sericata (Diptera:Calliphoridae).
The blowflies Lucilia cuprina Wiedmann and Lucilia sericata Meigen (Diptera:Calliphoridae) are facultative ectoparasites of warm blooded vertebrates, particularly domestic sheep. Despite being similar in morphology and ecology, the two species and different populations of each species, are known to vary in their importance as pests in different regions of the world. To elucidate the genetic bas...
