RESUMEN
This study aimed to carry out a malaria situation analysis, species composition and susceptibility levels of the main malaria vector, Anopheles stephensi, to different insecticides in Bashagard. A longitudinal survey was conducted in 2 randomly selected villages in Bashagard. Malaria vectors were sampled by dipping method for the larvae and hand catch, night-biting catch, total catch, and shelter pit collection for the adults. Standard WHO susceptibility tests were used for a variety of insecticides on F1 progeny of An. stephensi reared from wild-caught females. In total, 693 adult anopheline mosquitoes and 839 third and fourth-instar larvae were collected and identified. They comprised 7 species; the most abundant adult and larvae anopheline mosquito was An. dthali (40.7% and 30.5% respectively). An. culicifacies (24.2%) and An. stephensi (16.7%) were the next most common species for adult mosquitoes. An. stephensi was fully susceptible to malathion and pyrethroid insecticides but resistant to DDT and tolerant to dieldrin.
