In this study we 1) describe the abundance of Anopheles and culicine immatures in different water body types in urban Malindi, Kenya, 2) compare Anopheles immature density in relation to culicine immature density, and 3) identify characteristics that influence the likelihood of water bodies being co-colonized by Anopheles and culicines. Entomological and environmental cross-sectional surveys conducted in 2001 and 2002 were used in the analysis. A total of 889 Anopheles and 7,217 culicine immatures were found in diverse water body types in 2001 and 2002. Car-track pools (n = 45) and unused swimming pools (n = 25) comprised 61% (70 of 115) of all water bodies found and served as the main habitats for Anopheles immatures. Of the 38 water bodies found containing Anopheles immature mosquitoes, 63% (24 of 38) were car-track pools and unused swimming pools. Culicine immatures utilized several water body types as habitats. We found that Anopheles and culicine immatures had higher density when occurring individually compared to when they occurred simultaneously. We determined that season, permanency, and water body area size influenced the likelihood of water bodies being simultaneously positive for Anopheles and culicines. Though Anopheles immatures were found in diverse water body types, their numbers were low compared to culicine immatures. The low density of Anopheles immatures suggests that Anopheles larval control is an achievable goal in Malindi.
在本研究中，我们：1）描述肯尼亚马林迪市不同水体类型中按蚊和库蚊幼虫的丰度；2）比较按蚊幼虫密度与库蚊幼虫密度；3）确定影响水体被按蚊和库蚊共同定殖可能性的特征。分析使用了2001年和2002年进行的昆虫学和环境横断面调查。2001年和2002年在不同水体类型中共发现889只按蚊幼虫和7217只库蚊幼虫。汽车轨道积水池（n = 45）和废弃游泳池（n = 25）占所有发现水体的61%（115个中的70个），并作为按蚊幼虫的主要栖息地。在发现含有按蚊幼虫的38个水体中，63%（38个中的24个）是汽车轨道积水池和废弃游泳池。库蚊幼虫利用多种水体类型作为栖息地。我们发现，按蚊和库蚊幼虫单独出现时的密度高于它们同时出现时的密度。我们确定季节、永久性和水体面积大小会影响水体同时出现按蚊和库蚊阳性的可能性。尽管在不同水体类型中都发现了按蚊幼虫，但与库蚊幼虫相比数量较少。按蚊幼虫的低密度表明在马林迪控制按蚊幼虫是一个可以实现的目标。
