Publisher Summary This chapter reviews the morphology and structure of polytene
chromosomes. The chapter focuses on the gene mapping and building of cytogenetic maps …

Pesticide resistance is an evolutionary phenomenon (Dobzhansky 1951), which cannot be
fully understood without genetic data. Genetic studies are a major tool in developing …

The last 50 years of research into infections in Australia and New Zealand caused by larvae
of the sheep blowfly, Lucilia cuprina, have significantly advanced our understanding of this …

The cytochrome P450 gene superfamily is represented by 90 sequences in the Drosophila
melanogaster genome. Of these 90 P450 sequences, 83 code for apparently functional …

Messenger RNA levels of the cytochrome P450 gene CYP6A1 were measured in the
insecticide resistant Diazinon-R 'Rutgers' strain and in the susceptible strain sbo of the …

Laboratory and field experimentation has shown that resistant and susceptible diazinon
genotypes of flies collected from the field may have similar fitness in an environment free of …

Maynard Smith et al. 1 have recently suggested that newly evolved phenotypes will be more
variable than long-established ones when developmental constraints have evolved through …

The function of the intracellular pupil mechanism is examined by comparing the responses
of photoreceptors in normal flies with those from white-eyed flies that lack the pupil. In white …

The level of expression of the Cyp6a2 gene is much higher in the DDT-resistant 91-R strain
than in the susceptible 91-C strain of Drosophila melanogaster (Waters et al.(1992b) Proc …

Up‐regulation of detoxifying enzymes in insecticide‐resistant strains of the house fly is a
common mechanism for metabolic resistance. However, the molecular basis of this …
