[Inhibition by organophosphate insecticides of carboxylesterase in Helicoverpa armigera]
Acta Entomologica Sinica 41 (Suppl.), S12-S18
Abstract: The inhibition of 22 organophosphates (OP) to the activity of carboxylesterase, using alpha- and ß-naphthyl acetate as substrate separately, was investigated in cotton bollworms (Helicoverpa armigera). The inhibition potential of paraoxon, dichlorvos, SV1, quinalphos, malaoxon, IBP were much stronger than the other insecticides tested. The relationship between chemical structure and the inhibition potential to carboxylesterase was also studied. The inhibition potential was: phosphate > phosphorothionate, phosphorothiolate > phosphorodithioate, phosphoramidate > phosphorothiolamidate and (C₂H₅O) ₂OP > (CH₃O) ₂OP.
