将冈比亚按蚊和致倦库蚊（双翅目：蚊科）成年蚊子暴露于从用拟除虫菊酯杀虫剂制剂按推荐浓度（40 mg ai/m(2) 的高效氯氰菊酯 SC 处理；50 mg ai/m(2) 的高效氯氰菊酯 SC；50 mg ai/m(2) 的氟氯菊酯 EW；25 mg 的溴氰菊酯 WT）处理的聚酯网复制样品中 3 分钟。 ai/m(2))，或仅用这些剂量的四分之一进行治疗。在马拉维家庭使用蚊帐 4 个月后，化学检测显示蚊帐上的拟除虫菊酯沉积物略低于目标浓度。将两种处理浓度下的拟除虫菊酯生物测定结果与按蚊进行比较，溴氰菊酯的死亡率(99.7-100%)显着高于其他化合物(高效氯氰菊酯94-96%，氟氯氰菊酯80-89%)。库蚊生物测定死亡率较低（高效氯氰菊酯 56-74%；氟氯氰菊酯 63-65%；溴氰菊酯 50-81%），三种拟除虫菊酯杀虫剂在推荐剂量下的结果没有显着差异。
Adult mosquitoes, Anopheles gambiae Giles and Culex quinquefasciatus Say (Diptera: Culicidae), were exposed for 3 min to replicate samples of polyester netting cut from replicate bednets treated with pyrethroid insecticide formulations at the recommended concentration (alphacypermethrin SC at 40 mg ai/m(2); eyfluthrin EW at 50 mg ai/m(2); deltamethrin WT at 25 mg ai/m(2)), or treated with only a quarter of those dosages. After 4 months domestic use of the bednets in Malawi, chemical assays showed that pyrethroid deposits on the netting were somewhat less than the target concentrations. Comparing the pyrethroid bioassay results with Anopheles at both treatment concentrations, deltamethrin gave significantly higher mortality (99.7-100%) than the other compounds (alphacypermethrin 94-96%, cyfluthrin 80-89%). Culex bioassay mortality was lower (alphacypermethrin 56-74%; cyfluthrin 63-65%; deltamethrin 50-81%) and results with the three pyrethroid insecticides at their recommended doses did not differ significantly.
