In five Tanzanian villages, nets impregnated with permethrin or lambdacyhalothrin were given out. The people received them enthusiastically and brought their nets for re-impregnation at six monthly intervals. Bioassays showed that the insecticidal power of permethrin impregnated nets remained adequate for six months unless the nets were washed. Nets with 30 mg lambdacyhalothrin/m2 retained high insecticidal power despite washing, but this dose caused temporary cold-like symptoms in those sleeping under freshly treated dry nets. Methods by which durable bednets might be made affordable by Tanzanian villagers are discussed.
在坦桑尼亚的五个村庄发放了用氯菊酯或高效氯氟氰菊酯浸泡过的蚊帐。人们热情地领取了这些蚊帐，并每隔六个月就把蚊帐拿来重新浸泡。生物测定表明，除非蚊帐被清洗，用氯菊酯浸泡过的蚊帐的杀虫效力能保持六个月。每平方米含30毫克高效氯氟氰菊酯的蚊帐尽管经过清洗仍保持高杀虫效力，但这个剂量会使睡在刚处理过的干蚊帐下的人出现类似感冒的暂时症状。文中讨论了使坦桑尼亚村民能够买得起耐用蚊帐的方法。
