Update on resistance status of Anopheles gambiae s.s. to conventional insecticides at a previous WHOPES field site Yaokoffikro 6 years after the political crisis in Côte dIvoire

摘要

BackgroundAt Yaokoffikro field site near Bouaké, in central Côte d'Ivoire, a group of experimental huts built in 1996 served over many years for the evaluation of insecticides against highly resistant mosquitoes. Breeding sites of mosquitoes and selection pressure in the area were maintained by local farming practices until a war broke out in September 2002. Six years after the crisis, we conducted bioassays and biochemical analysis to update the resistance status of Anopheles gambiae s.s. populations and detect other potential mechanisms of resistance that might have evolved.
