Cross-Resistance Patterns Among Lucilia cuprina (Diptera: Calliphoridae) Resistant to organophosphorus Insecticides
Strains of Lucilia cuprina (Wiedemann) have been characterized as having low, internlcdiate, or high levels of esterase-mediated hydrolysis of the organophosphorus insecticide, chlorfenvinphos. TheseExpand

Predicting resistance and managing susceptibility to cyromazine in the Australian sheep blowfly Lucilia cuprina
Four cyromazine-resistant variants of Lucilia cuprina were selected after ethyl methanesulfonate mutagenesis and screening above the concentration of cyromazine lethal to susceptibles. Resistance isExpand

Biochemical characterization of the products of the Adh loci of Drosophila mojavensis
The electrophoretic pattern of alcohol dehydrogenase (ADH) of Drosophilia mojavensis is composed of multiple bands. In previous studies from this laboratory we suggested on the basis of geneticExpand

Differential regulation of duplicate alcohol dehydrogenase genes in Drosophila mojavensis.
These studies report the existence of multiple forms of alcohol dehydrogenase in extracts of Drosophila mojavensis. The existence of these forms can be best explained by the hypothesis of aExpand

A phenol oxidase polymorphism in Drosophila melanogaster
A phenol oxidase enzyme (PHOX) has been identified on electrophoretic gels following simple activation by 50% propan-2-ol in phosphate buffer. Three electrophoretically detectable allozymes wereExpand

Molecular genetic characterization of a locus that contains duplicate Adh genes in Drosophila mojavensis and related species.
Drosophila mojavensis and other species of the mulleri subgroup contain a duplicate gene encoding the enzyme alcohol dehydrogenase (ADH). Studies on the genetic relationship of the two genes usingExpand

ORIGIN AND EXPRESSION OF AN ALCOHOL DEHYDROGENASE GENE DUPLICATION IN THE GENUS DROSOPHILA
The origin of variation in regulatory mechanisms and the subsequent evolution of different regulatory systems may have fundamental importance in transspecific evolution (e.g., Dobzhansky et al.,Expand

Fitness and Asymmetry Modification as an Evolutionary Process A Study in the Australian Sheep Blowfly, Lucilia cuprina and Drosophila melanogaster
Biologists have usually considered resistance to pesticides as an applied problem, albeit one of considerable importance. An ever increasing range of organisms have become resistant to chemicalExpand

The Acetylcholinesterase Gene and Organophosphorous Resistance in the Australian Sheep Blowfly, Lucilia Cuprina
Acetylcholinesterase (AChE), encoded by the Ace gene, is the primary target of organophosphorous (OP) and carbamate insecticides. OP resistance has developed via a range of mechanisms in insect manyExpand
