[Study on inhibiting effect of 14 insecticides on esterase of Culex tritaeniorhynchus from five geographic populations].
Isoelectrofocusing technique was used to study the inhibiting effect of 14 insecticides on esterase isozymes of Culex tritaeniorhynchus from natural populations in Fuzhou, Shanghai, Qingdao, Dalian and Beijing areas. Among 14 insecticides, organophosphates were good inhibitors to all esterase isozymes, but Allethrin, Propoxur, DDT, Dieldrin had no or almost no inhibiting effect on esterase. 26 esterase isozyme bands of Culex tritaeniorhynchus were revealed by isoelectrofocusing.
