Pyrethroid resistance in adult mosquitoes, Aedes Aegypti from Jaipur City, Rajasthan

In current study, resistance status was evaluated in adult mosquitoes of Aedes aegypti against two synthetic pyrethroids from urban area of Jaipur, Rajasthan during July, 2015 to January, 2017. Mortality percentage for field and susceptible mosquitoes stain was determined against cypermethrin and permethrin by regression analysis using log probit method by using CDC bottle bioassay. The resistance ratio (RR) against permethrin was observed to be RRLC₅₀= 2 and RRLC₉₀=2.5 in field collected population, whereas, regarding cypermethrin resistance level was observed at RRLC₅₀= 1.5 and RRLC₉₀= 3.16 as compared to laboratory susceptible population.
