Residual efficacy of deltamethrin 2.5 wp on various types of surfaces was tested against Anopheles culicifacies under field conditions using WHO standard procedure. Deltamethrin was most effective on the thatched surface and produced 100% mortality of An. culicifacies adults up to 12 weeks, even when exposed at the lowest dose /12.5 mg/m2. It was least effective on brick surface and 100% mortality was observed only for three weeks. The efficacy was observed for 8 and 7 weeks on mud and cement surfaces, respectively. However, at the higher rate of application, i.e. 25 mg/m2, 100% mortality of this species was obtained for 12, 10, 9 and 12 weeks on mud, cement, brick and thatch surfaces, respectively.
采用世界卫生组织标准程序，在野外条件下测试了2.5%溴氰菊酯可湿性粉剂在不同类型表面上对库氏按蚊的残留药效。溴氰菊酯在茅草表面效果最佳，即使以最低剂量（12.5毫克/平方米）暴露，在长达12周的时间里库氏按蚊成虫的死亡率仍达100%。在砖块表面效果最差，仅在三周内观察到100%的死亡率。在泥土和水泥表面分别观察到8周和7周的药效。然而，在较高施用量（即25毫克/平方米）下，该蚊种在泥土、水泥、砖块和茅草表面的死亡率分别在12周、10周、9周和12周达到100%。
