Three trials with torn bed nets impregnated with permethrin and deltamethrin were made under field conditions at the Soumousso Field Station and the Vallée du Kou rice-field area, both in Burkina Faso, and the Djoumouna fish pond area in the Congo Republic. Even a considerably torn correctly impregnated bed net could be an useful method for limiting human-anopheline contacts. But bed nets in poor condition, i.e. too little impregnated and too much torn, cannot protect the users against anopheline bites. Protection increases with insecticide concentration, but at a high dosage insecticide could have more a repellent than a killing effect. Therefore a balance has to be found for the optimum rate of insecticide treatment of bed nets to obtain a real reduction in malaria transmission and morbidity, in every epidemiological situation.
在布基纳法索的苏穆苏野外工作站和库河谷稻田地区以及刚果共和国的朱穆纳鱼塘地区的野外条件下，对用氯菊酯和溴氰菊酯浸渍的破损蚊帐进行了三项试验。即使是破损相当严重但浸渍正确的蚊帐，也可能是限制人与按蚊接触的一种有用方法。但是，状况不佳的蚊帐，即浸渍过少且破损过多的蚊帐，无法保护使用者免受按蚊叮咬。防护效果随杀虫剂浓度的增加而提高，但高剂量的杀虫剂可能更多地起到驱避作用而非杀灭作用。因此，在每种流行病学情况下，都必须找到蚊帐杀虫剂处理的最佳比例，以真正减少疟疾传播和发病率。
