Characterization and monitoring of deltamethrin-resistance in Anopheles culicifacies in the presence of a long-lasting insecticide-treated net intervention.

ABSTRACT:

Background

Deltamethrin-impregnated, long-lasting insecticidal nets (LLINs) were distributed in the study area from November 2014 to January 2015 to evaluate their impact on malaria transmission in the presence of insecticide-resistant vectors. Studies were carried out in 16 selected clusters in Keshkal sub-district, Chhattisgarh State, India to monitor and characterize deltamethrin resistance in Anopheles culicifacies sensu lato.

Results

Deltamethrin susceptibility of An. culicifacies decreased in a post-LLIN survey compared to a pre-LLIN survey and was not significant (p > 0.05) while, the knockdown values showed significant increase (p < 0.05). Pre-exposure to piperonyl butoxide, triphenyl phosphate showed synergism against deltamethrin (p < 0.001). Biochemical assays sho
