Abstract
The pyrethroids efficacy in larvae and adults of Aedes aegypti from semi-arid zone, Jaipur was investigated using World Health Organization standard procedures. Studies were carried out on 4^th instar larvae and female adults of Aedes aegypti and percent mortality determined by log probit analysis. Data of LC₅₀ and LC₉₀ values were observed to be 0.0003 and 0.0794 ppm and 0.0063 and 0.0158 ppm for cypermethrin and permethrin against larvae of Aedes mosquitoes vector respectively. The results showed that both larvae and adults of A. aegypti were more susceptible to cypermethrin than permethrin as tested. Mortality rates after exposing adults to discriminating concentrations showed LC₅₀ and LC₉₀ to be 0.0019 and 1.0501 ppm and 0.1000 and 0.3981 ppm for cypermethrin and permethrin respectively, when subjected for 60 min. time exposure. As the study area is endemic outbreak prone, the present study of pyrethroids susceptibility assay could yield a powerful approach in mosquito’s population control strategy.
