Abstract

The present study was designed to evaluate the susceptibility of Culex quinquefasciatuns against malathion in Sargodha district of Pakistan. The activities of detoxifying enzymes i.e., β-esterases, GSTs and monooxygenases were also estimated. Our results revealed 100 percent mortality in insecticide treated groups after 24 hours of exposure. There was no difference in the activities of insecticide detoxifying enzymes between control and treated groups. We concluded from our work that malathion is still effective against C. quinquefasciatuns in the area for control of mosquito population.
