Adult bioassay was conducted in the laboratory on two populations of Culex fuscocephala, a vector of Japanese encephalitis (JE) in India, against two organochloride compounds (DDT and dieldrin), an organophosphate compound (malathion), a carbamate pesticide (propoxur) and two synthetic pyrethroids (deltamethrin and cyfluthrin) using WHO techniques. The adult populations from Mandya an irrigated agricultural area, and Mysore, a non-agricultural place in Karnataka, India, have been employed for the experiments JE outbreaks were reported from these places at different times. Among the insecticides used malathion in 5% concentration was found to be the most effective while, cyfluthrin (0.05%) and deltamethrin (0.025%) were very effective in much lesser concentration For both propoxur (0.1%) and DDT (4.0%) the two populations of Cx. fuscocephala expressed least susceptibility in terms of the LT50. Against dieldrin (0.4%), cyfluthrin, DDT and malathion Mysore population showed relatively more susceptibility than Mandya population. However for deltamethrin and propoxur the Mandya population registered less tolerance than the Mysore population. Thus adult population responses to different insecticides are variable in the present study.
