TLDR
Using a partial cDNA of this gene, genomic fragments generated by EcoR1 restriction enzyme in various laboratory and natural populations of Culex that are OP resistant are probed.Abstract:
Increased detoxification by esterases is a common mechanism of resistance to organophosphate (OP) insecticides in insects. Utilizing a partial cDNA of this gene, we probed genomic fragments generated by EcoR1 restriction enzyme in various laboratory and natural populations of Culex that are OP resistantread more

Gene amplification and insecticide resistance
Chris Bass,Linda M. Field +1 more
TL;DR: This mini-review summarises the involvement of gene duplication/amplification in the insecticide/acaricide resistance of insect and mite pests and highlights recent developments in this area in relation to P450-mediated and target-site resistance.
Journal ArticleDOI
Worldwide migration of amplified insecticide resistance genes in mosquitoes.
TL;DR: The results suggest that amplified esterase B2 genes originated from an initial event that has subsequently spread organophosphate insecticide resistance by migration, and that electrophoretically dissimilar esterases B varied considerably.
Biochemical genetics and genomics of insect esterases
TL;DR: This article reviews the biochemistry and genetics of insect esterases, focusing mainly on developments, from a genomics perspective and the bulk of it is organized around the major clades of insectEsterases as revealed by the comparative genomic analysis.
Book ChapterDOI
Biochemical Genetics and Genomics of Insect Esterases
TL;DR: The Comprehensive Molecular Insect Science (CMIIS) as discussed by the authors is a complete reference encompassing important developments and achievements in modern insect science, including reviews on the ecdysone receptor, lipocalins, and bacterial toxins.
Journal ArticleDOI
Studying stress: the importance of organism‐level responses
TL;DR: The importance of studying the effects of stress on individual organisms is addressed by considering the use of individual-level information to elucidate the mechanistic bases of interpopulation variation; predict population-level effects; and monitor stress in natural communities.

Molecular Cloning: A Laboratory Manual
TL;DR: Molecular Cloning has served as the foundation of technical expertise in labs worldwide for 30 years as mentioned in this paper and has been so popular, or so influential, that no other manual has been more widely used and influential.

TL;DR: The finding that selection by pesticides may result in the amplification of genes encoding detoxifying enzymes in whole, normally developed, reproducing insects emphasizes the biological importance of this mechanism and opens new areas of investigation in pesticide resistance management.
Journal ArticleDOI
Molecular evidence that insecticide resistance in peach-potato aphids (Myzus persicae Sulz.) results from amplification of an esterase gene.
TL;DR: Qualitative differences between restriction patterns in different clones of resistant aphids correlated with the presence or absence of a specific chromosome translocation and with production of E4 or FE4.

Carbamate-resistance in mosquitos. Selection of Culex pipiens fatigans Wiedemann (=C. quinquefasciatus Say) for resistance to Baygon.
TL;DR: The authors consider the relatively slow rate of development of resistance to Baygon, the reduced expressivity of the resistance character in adults, and its specificity for the selective agent and for closely related carbamates to be encouraging indications as to the usefulness of this class of compounds for mosquito control.
