To test the efficacy of nets treated with repellent and insecticide against susceptible and insecticide-resistant An. gambiae mosquito populations, we impregnated mosquito bed nets with an insect repellent mixed with a low dose of organophosphorous insecticide and tested them in a rice-growing area near Bobo-Dioulasso, Burkina Faso. During the first 2 weeks posttreatment, the mixture was as effective as deltamethrin alone and was more effective at killing An. gambiae that carried knockdown resistance (kdr) or insensitive acetylcholinesterase resistance (Ace1(R)) genes. The mixture seemed to not kill more susceptible genotypes for the kdr or Ace1(R) alleles. Mixing repellents and organophosphates on bed nets could be used to control insecticide-resistant malaria vectors if residual activity of the mixture is extended and safety is verified. specialized BURKINA FASO 052 14 11 1707-1714 2008 1080-6040 https://www.documentation.ird.fr/hor/fdi:010044050 10.3201/eid1411.071575 1080-6040 [F B010044050] https://www.documentation.ird.fr/hor/fdi:010044050 https://www.documentation.ird.fr/intranet/publi/2008/11/010044050.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-12-05 2021-06-08 fdi:010044050 fre
