Abstract:
Insecticide based vector control approaches are facing challenges due to the development of resistance in vector mosquitoes. Therefore, a proper resistance surveillance programme using baseline lethal concentrations is crucial for the resistance management strategies. Currently, the World Health Organization’s (WHO) diagnostic doses established for Aedes aegypti and Anophlese are being used to study the resistance status of Aedes albopictus. In this study we established the diagnostic doses for permethrin, deltamethrin and malathion using a known susceptible reference strain and 5 field collected populations were screened against these doses following the WHO protocol. This study established the diagnostic dose of malathion 3.4%, permethrin 0.45% and deltamathrin 0.08%, that differs from the WHO doses. Among the insecticides tested on 5 wild populations, only deltamethrin showed high effectiveness. While, different susceptibility and resistance patterns where observed against permethrin, malathion and DDT 4%. This study may facilitate the health authorities in future to improve chemical based vector control operations in the dengue endemic areas.
