Laboratory evaluation of Fendona 6SC® treated bednets and Interceptor® long-lasting nets against Anopheles gambiae sl in Burkina Faso

---

Résumé

Insecticide-treated bednets play a cornerstone role in the efforts to control malaria. Bednets entomological efficacy is the determinant factor of their use to control malaria. In this study, we compared under laboratory conditions, the efficacy of two long-lasting nets (PermaNet® versus Interceptor®) and two treatments kits KO TAB®(deltamethrin) versus Fendona 6SC®(alpha-cypermethrin) against Anopheles gambiae sl malaria vectors. The efficacy of washed and unwashed bednets was assessed by contact bioassays using World Health Organization (WHO) cones. Three to five-days-old mosquitoes were exposed to the netting for 3 min; the median and 95% knockdown time, the after 24 h mortality was recorded for each type of bednet. The mortality after 24 h was equivalent for the Fendona 6SC® treated bednets and the KO TAB® treated bednets [79.4% confidence limits (CL)(73.9–84.6) and …
