The insecticides carbaryl and Folithion were tested on a village scale in the vicinity of Lagos, Nigeria, by the WHO Insecticide Testing Unit in 1963. Whereas carbaryl reduced the density of anophelines and culicines for two months, Folithion greatly reduced their density for six months or more. The mortality among mosquitos leaving treated dwellings and caught in window-traps in the carbaryl-treated village was fairly high for only one month after treatment, but in the Folithion-treated village it was high for seven months. Bio-assay results showed that Folithion was effective on mud for two-and-a-half months, on wood for seven months, and on thatch for six months. Carbaryl was not effective on mud; on wood it was effective for nine months or more, and on thatch for six to nine months.Anopheles hargreavesi was found to be more exophilic than Anopheles gambiae or culicines.
1963年，世界卫生组织杀虫剂测试单位在尼日利亚拉各斯附近的村庄对杀虫剂西维因和伏杀硫磷进行了大规模测试。西维因使按蚊和库蚊密度降低了两个月，而伏杀硫磷使它们的密度大幅降低了六个月或更长时间。在西维因处理过的村庄，经处理的房屋中飞出并被窗户诱捕器捕获的蚊子死亡率仅在处理后一个月内相当高，但在伏杀硫磷处理过的村庄，死亡率在七个月内都很高。生物测定结果表明，伏杀硫磷在泥土上的有效期为两个半月，在木材上为七个月，在茅草上为六个月。西维因在泥土上无效；在木材上有效期为九个月或更长时间，在茅草上为六至九个月。发现哈氏按蚊比冈比亚按蚊或库蚊更倾向于栖息在室外。
