[Preliminary studies on levels of sensitivity to phosphoric esters in the Italian population of the Culex pipiens complex]. 1982

F Villani, and G Majori, and R Romi

A preliminary survey of the susceptibility level to organophosphate (OP) insecticides in six populations of Culex pipiens from Central Italy has been carried out. The correlation between OP resistance and highly active esterase electromorphs has also been investigated. The bioassay and electrophoresis results show an association between OP resistance and the highly active esterase allele Est-3A and confirm what it was found in populations of C. pipiens from Southern France. Est-3A appears to be a reliable indicator of OP resistance in mosquitoes of italian C. pipiens.
