Journal ArticleDOI
An amino acid substitution on the second acetylcholinesterase in the pirimicarb-resistant strains of the peach potato aphid, Myzus persicae.
TL;DR: cDNAs encoding two acetylcholinesterases (AChEs) were isolated from the peach potato aphid, Myzus persicae, and a single amino acid substitution of Ser431Phe on MpAchE2 was found in the pirimicarb resistant strains.
Journal ArticleDOI
An amino acid substitution attributable to insecticide-insensitivity of acetylcholinesterase in a Japanese encephalitis vector mosquito, Culex tritaeniorhynchus.

TL;DR: The F455W replacement in the Ace2 gene is solely responsible for the insecticide-insensitivity of AChE in TYM mosquitoes.
Journal ArticleDOI

TL;DR: The identification and characterization of the gene responsible for the dimolting (mod) mutant that undergoes precocious metamorphosis with fewer larval–larval molts is reported, suggesting that authentic epoxidized JHs are not essential in very young larvae of B. mori.
Journal ArticleDOI
Fenitroxon insensitive acetylcholinesterases of the housefly, Musca domestica associated with point mutations.
TL;DR: The cDNA of AChE in the housefly, Musca domestica, was sequenced and individual flies were genotyped by this gene in an inhibition assay of A ChE activity with an organophaspate, fenitroxon, and mutations at Gly and Tyr were associated with the insensitivity.
Journal ArticleDOI
Sequence of a cDNA encoding acetylcholinesterase from susceptible and resistant two-spotted spider mite, Tetranychus urticae.
TL;DR: Acetylcholinesterase from two-spotted spider mites was compared between an organophosphate susceptible (TKD) and a resistant (NCN) strain, and the inhibition of AChE by DDVP, ambenonium, eserine and n-methyl-eserine showed that NCN was more insensitive than TKD.
