Insecticide resistance is an inherited characteristic involving changes in one or more insect
gene. The molecular basis of these changes are only now being fully determined, aided by …

The past ten years have seen the elucidation of the molecular basis of insect resistance to
many chemical insecticides. Target genes, mostly in the nervous system, have been …

Mosquitoes in the Culex (Culex) pipiens complex of species, known as vectors of periodic
filariasis and deadly encephalitides, have recently emerged as important vectors of West …

Acetylcholinesterase (AChE) is the target of two major insecticide families,
organophosphates (OPs) and carbamates. AChE insensitivity is a frequent resistance …

Acetylcholinesterase (AChE) insensitive to organophosphate and carbamate insecticides
has been identified as a major resistance mechanism in numerous arthropod species …

A house fly strain, ALHF, was collected from a poultry farm in Alabama after a control failure
with permethrin, and further selected in the laboratory with permethrin for five generations …

Resistance-modified acetylcholinesterases have been described in many insect species
and sequencing of their genes has allowed several point mutations to be described. Most …

Genetic changes conferring adaptation to a new environment may induce a fitness cost in
the previous environment. Although this prediction has been verified in laboratory …

Abstract A 2.2‐kb full length cDNA containing an ORF encoding a putative
acetylcholinesterase (AChE) precursor of 673 amino acid residues was obtained by a …

A cDNA sequence encoding a Drosophila Ace-paralogous acetylcholinesterase (AChE)
precursor of 701 amino acid residues was identified as the second AChE gene (Ace2) …
