阿拉伯按蚊和阿氏按蚊。通过在房屋中收集除虫菊酯喷布和在肯尼亚西部一个毗邻阿赫罗水稻灌溉计划的村庄捕捉人饵收集除虫菊酯；并使用相同的方法。冈比亚.l.安丹。在甘蔗产区的米瓦尼村采集虫体，用ELISA法测定恶性疟原虫的子孢子率。平均子孢子率分别为1.1%和4.3%。阿拉比森和阿恩。Funestus和Miwani分别为6.0%。冈比亚.l.4.3%的INAN。昆虫接种率(EIR)既来自人类诱饵收集(IR-HBC)，也来自于在室内休息的人类吸血雌性动物的比例(IR-HBF)。IR-HbF似乎是反映EIR的更真实的指标。在艾希罗和米瓦尼，人们平均分别被感染叮咬416次和91次/人/年。主要载体为EAN。万岁的安丹。冈比亚.l.在米瓦尼。鉴于阿赫罗疟疾的密集和常年传播，应考虑使用杀虫剂控制病媒传播，而在传播是季节性的米瓦尼，可以用氯氰菊酯浸泡的蚊帐替代室内喷洒。必须以有效的抗疟疾药物的供应来加强这些措施。
Anopheles arabiensisandAn. funestuswere collected by pyrethrum spray sheet collections in houses and by human-bait catches at a village in western Kenya adjacent to the Ahero rice irrigation scheme; and using the same methods,An. gambiaes.l. andAn. funestuswere collected at Miwani, a village in the sugar-cane belt.Plasmodium falciparumsporozoite rates were determined by ELISA. At Ahero the mean sporozoite rates were 1·1% and 4·3% inAn. arabiensisandAn. funestus, respectively, while at Miwani the rates were 6·0% inAn. gambiaes.l. and 4·3% inAn. funestus.Entomological inoculation rates (EIR) were derived from both human-bait collections (IR-HBC) and by the proportion of human blood-fed females caught resting indoors (IR-HBF). The IR-HBF appeared to be a more realistic index of EIR. At Ahero and Miwani people were exposed to an average of 416 and 91 infective bites/person/year, respectively. The main vectors wereAn. funestusat Ahero andAn. gambiaes.l. at Miwani. In view of the intense and perennial malaria transmission at Ahero, vector control by insecticides should be considered, while at Miwani, where transmission is seasonal, permethrin-impregnated bed nets could be an alternative to indoor spraying. These measures must be augmented with availability of effective antimalarials.
