Targeted application of an organophosphate-based paint to windows and doors against A. coluzzii resistant to pyrethroids under real-life conditions in Vallée du Kou, Burkina Faso

Insecticide Paint Inesfly 5A IGR™ was applied to doors and windows and tested in combination with pyrethroid-treated LLINs. The residual efficacy was evaluated monthly by WHO bioassays using Anopheles gambiae ‘Kisumu’ and local populations of Anopheles coluzzii resistant to pyrethroids. The frequency of L1014F kdr and Ace-1 R G119S mutations was, respectively, reported throughout the study. (MapVEu VBP0000296)
