在冈比亚的萨鲁贾村，疟疾主要通过冈比亚按蚊复合体的蚊子传播，人们对用三种拟除虫菊酯杀虫剂之一的氯氰菊酯40 mg/m（2）处理过的蚊帐的可接受性和功效进行了试验。氯菊酯500 mg/m2，氯氟氰菊酯10 mg/m2。在用杀虫剂处理过的蚊帐中发现的活蚊子比在对照蚊帐中少。在用氯氰菊酯处理的蚊帐下发现的死蚊子明显多于用氯菊酯或三氟氯氰菊酯处理的蚊帐。用每种杀虫剂处理过的蚊帐的使用者中有一部分人报告了副作用，但都不严重，而且处理组之间的流行率相似。在生物测定中，用氯氰菊酯处理过的未洗蚊帐比用氯菊酯或氯氟氰菊酯处理过的蚊帐更能有效地杀死按蚊。无论使用哪种杀虫剂，清洗蚊帐后，杀灭活动都有所减少。用氯氰菊酯处理过的蚊帐被广泛接受，可有效杀灭按蚊，因此应评估其对疟疾传播的个人防护作用。
In the Gambian village of Saruja, where malaria is transmitted mainly by mosquitoes of the Anopheles gambiae complex, a trial was undertaken of the acceptability and efficacy of bednets treated with one of three pyrethroid insecticides alphacypermethrin 40 mg/m(2). permethrin 500 mg/m(2) and lambdacyhalothrin 10 mg/m(2). Fewer mosquitoes were found alive under nets treated with insecticide than under control nets. Significantly more dead mosquitoes were found under nets treated with alphacypermethrin than under nets treated with permethrin or lambdacyhalothrin. Side-effects were reported by a proportion of the users of nets treated with each of the insecticides, but none were severe and their prevalence was similar between treatment groups, Unwashed nets treated with alphacypermethrin were more effective at killing anopheline mosquitoes in bioassays than nets treated with permethrin or lambdacyhalothrin. Killing activity was reduced when nets were washed, irrespective of which insecticide was used, Bednets treated with alphacypermethrin are well accepted, effectively killed anopheline mosquitoes and should therefore be evaluated for personal protection against malaria transmission.
