Susceptibility status of Ae. albopictus and Ae. aegypti was evaluated in different localities of four towns namely Samanabad, Nishtar, Ravi and Iqbal town in Lahore district, Eastern Punjab, Pakistan.Susceptibility test using WHO test kits was applied on adult females (12-24) hrs. Post emergence (non-blood fed) live mosquitoes under laboratory conditions at 27-29 0C temperature and 85-95% humidity. Ae. aegypti and Ae. Albopictus were found resistant to 4% DDT with < 36.28% mortality. Both species were also found resistant against 0.05% deltamethrin, 0.05%, lambdacyhalothrin and 0.75% permethrin at all localities with <75.00%, <87.00% and <81.05% mortalities respectively. Ae. albopictus was found resistant to0.1% bendiocarbat Samanabad and Iqbal towns, while resistance possible to be confirmed at Nishtar and Ravi towns. Ae. aegypti found susceptible to 0.1% bendiocarbat Samanabad town, resistant at Ravi town and resistance possible to be confirmed (incipient) at Nishtar and Iqbal towns with 92.23% and 94.00% mortalities. Malathion was found most suitable insecticide with 100% mortality rate in Ae. albopictus and Ae. aegypti at Lahore district. Alternative use of malathion and bendiocarb may be the best option to reduce dengue vector density.
