The findings demonstrate significant resistance to temephos in Ae. aegypti populations across urban areas of Tamil Nadu, underscoring the importance of regular resistance monitoring system and the implementation of integrated insecticide resistance management strategies. Although An. stephensi remains susceptible, continuous surveillance is important to maintain larvicidal efficacy. The outcomes of the study provide essential baseline data to inform and strengthen vector control programmes.
