At 2 sites in western Kenya targeted for future malaria vaccine trials, adult culicine mosquitoes were sampled over one year by 5 collection techniques to assess human exposure to potential vectors of pathogens other than malaria. Collections included 20,910 females representing 19 species in Kisian and 4,312 females of 11 species in Saradidi. Common species in Kisian included Culex quinquefasciatus (71.4%), Mansonia uniformis (15.8%), Ma. africana (6.2%), Aedes mcintoshi (2.0%), Coquillettidia fuscopennata (1.9%) and Ae. ochraceus (1.8%). Common species in Saradidi included Cx. quinquefasciatus (92.7%), Cx. nebulosus (4.5%) and Ma. uniformis (1.0%). Human-bait collections identified 16 man-biting culicine species in Kisian and 9 in Saradidi. Man-biting rates at Kisian for the 5 most common species were 1.8, 14.6 and 13.5 times higher than at Saradidi for indoor, outdoor and tent collections, respectively. Exposure indoors was estimated to be 1,277 bites/man/year at Kisian and 720 at Saradidi. Blood meal identification for 1,083 mosquitoes confirmed that the common culicine species feed primarily on humans and cows.
在肯尼亚西部两个计划开展未来疟疾疫苗试验的地点，通过5种采集技术在一年时间内对成年库蚊进行了采样，以评估人类接触除疟疾之外其他病原体潜在传播媒介的情况。采集的样本包括基西安的20910只雌蚊，分属19个物种，以及萨拉迪迪的4312只雌蚊，分属11个物种。基西安的常见物种包括致倦库蚊（71.4%）、同型曼蚊（15.8%）、非洲曼蚊（6.2%）、麦氏伊蚊（2.0%）、棕翅库蚊（1.9%）和 Ochraceus伊蚊（1.8%）。萨拉迪迪的常见物种包括致倦库蚊（92.7%）、朦胧库蚊（4.5%）和同型曼蚊（1.0%）。人饵诱捕采集发现，基西安有16种叮咬人类的库蚊，萨拉迪迪有9种。基西安最常见的5个物种在室内、室外和帐篷采集时的叮咬率分别比萨拉迪迪高1.8倍、14.6倍和13.5倍。据估计，基西安室内的暴露量为每人每年1277次叮咬，萨拉迪迪为720次。对1083只蚊子的血餐鉴定证实，常见的库蚊主要吸食人和牛的血液。
