Abstract

The LD 50 ,α naphthylacetate(α NA)esterase kinetics,α,β NA esterase activity and IC 50 of dichlorvos(DDVP),phoxim and malathion to Del R、2Cl R and susceptible (SP) strains of houseflies were determined. The resistances of the Del R and 2Cl R to DDVP, phoxim and malathion were 0 966～7 190 folds as much as those of the SP strain,indicating a low resistance level to organophosphate insecticides in the pyrethroid resistant houseflies. An obvious correlation of the carboxylesterase activity with IC 50 suggested that the carboxylesterase would play a significant role in the resistance to organophosphates in pyrethroid resistant houseflies.
