Relation of the sex chromosome to DDT resistance in the German cockroach
1. Reciprocal crosses were made between a DDT-resistant and a nonresistant strain of the German cockroach. 2. The techniques employed in rearing the roaches and obtaining toxicological data on the different strains, as well as the genetical and statistical procedures, are described. 3. The …

In vivo studies of suspected mechanisms of DDT-resistance in Blattella germanica (L.)
… of penetration, metabolism, and excretion of DDT have been studied in vivo in resistant and susceptible strains of the German cockroach, Blattella germanica (L.). The cockroaches were exposed to various DDT treatments for intervals ranging from 3 to 72 hours. DDT and its metabolites were …

Dichlorodiphenyltricholorethane (DDT) resistance mechanisms in Drosophila melanogaster and applications for the cowpea pest Clavigralla tomentosicollis
Control of insects by insecticides has led to resistance in both medical and agricultural pests as well as health and environmental concerns, and improved insect pest management (IPM) programs are necessary. The arrival of next-generation sequencing (NGS) and lowered sequencing costs provides the …

Genome-wide sequencing and an open reading frame analysis of DDT susceptible (91-C) and resistant (91-R) Drosophila melanogaster laboratory populations
DDT resistance in the Drosophila melanogaster resistant (91-R) and susceptible (91-C) fly lines has been previously examined for differential expression of transcripts and proteins. Here I present the first whole genome sequencing analysis of the 91-R and 91-C fly lines to identify structural …

Regulation of cytochrome P450 genes in drosophila melanogaster by the chemical environment
… the changes incurred in a strain selected for DDT resistance. Finally, I address the function of a brain-specific P450 that is highly conserved across Drosophila species, by using a GAL4/UAS RNAi system to study the reproductive effects of knocking down the gene Cyp4g15. Using molecular …

Investigating the role of glutathione and glutathione biosynthetic genes in the adaption of Anopheles gambiae to insecticides
… spraying (IRS). The development of insecticides resistance mitigates these approaches. Glutathione (GSH) is widely distributed among all living organisms, and is associated with detoxification pathways, especially the Glutathione S-transferases (GSTs). Its direct involvement and relevance in …
