Present studies were carried out to examine the insecticide susceptibility of larval and adults of Aedesaegypti ( Ae. aegypti ) from laboratory and field populations of Lahore.Four major groups of commonly used insecticides against Aedesaegyptii .e neo- nicotenoids (imidacloprid 5% SC), phenyl-pyrazoles (fipronil 2.5% EC), pyrethroids (deltamethrin 2.5% SC) and organophosphates (DDVP 50% EC)were tested against Aedesaegypti ,the common vector of dengue, according to WHO standard procedures. Larval and adult toxicity results were different for Wild and laboratory strains exposed to different groups of insecticides. Regression analysis showed significant trends in mortality. Imidacloprid proved to be the most toxic with LC 50 = 0.001 in wild larval strains of Aedesaegypti collected from different localities of Lahore while fipronil was most effective with LC 50 values of 0.005 μlitre/ml for wild larval samples. For both adults and larval strains deltamethrin showed least efficacy representing its high tolerance and resistance against pyrethroids. Laboratory samples were more resistant than field samples as resistant ratio varies (2.5-10) from insecticides to insecticides.
