The larval habitats of mosquitoes were investigated in Abeokuta, Nigeria in order to determine the breeding sites of the existing mosquito fauna and its possible public health implications on the residents of the City. The habitats were sampled between August 2005 and July 2006 using plastic dippers and a pipette. The habitats were grouped as ground pools/ponds, gutters/open drains, tyres, domestic containers and treeholes/ leaf axils. Ten species of mosquitoes were encountered in the five habitats namely Mansonia africana, M. uniformis, Culex quinquefasciatus, Aedes aegypti, Ae. albopictus, Ae. vittatus, Cx tigripes, Anopheles gambiae s.l., An. funestus and Eretmapodite clnysogaster. Ae. aegypti bred in all the habitats sampled while Cx quinquefasciatus bred in four habitats except tree holes/leaf axils. An. gambiae s.l and Ae. albopictus occurred in three habitats while other species bred only in one or two habitats. Ground pools and domestic containers recorded the highest number of species followed by gutters/open drains. Tree holes/leaf axils was the least preferred habitat with the lowest number of species occurrence. However, statistical analysis revealed non-significant difference in species occurrence in the five habitats. The availability of the habitats to support the breeding of Aedes, Culex and Anopheles, which are known vectors of urban yellow fever, lymphatic filariasis and malaria suggest that the residents ofAbeokuta City are at risk of mosquito-borne diseases. It is important that residents of the City are enlighten on the environmental factors that contribute to mosquito breeding and that the Government should institute proper sanitation measures to reduce mosquito breeding sites.
为了确定尼日利亚阿贝奥库塔现有蚊虫种类的滋生地及其对该市居民可能产生的公共卫生影响,对该地蚊虫的幼虫栖息地进行了调查。2005年8月至2006年7月期间,使用塑料水勺和移液管对这些栖息地进行了采样。栖息地被分为地面水池/池塘、排水沟/露天排水渠、轮胎、家用容器以及树洞/叶腋。在这五种栖息地中发现了十种蚊子,分别是非洲曼蚊、纯色曼蚊、致倦库蚊、埃及伊蚊、白纹伊蚊、条斑伊蚊、凶小库蚊、冈比亚按蚊(复合组)、嗜人按蚊和克莱氏真足蚊。埃及伊蚊在所有采样的栖息地中都有滋生,而致倦库蚊在除树洞/叶腋外的四种栖息地中滋生。冈比亚按蚊(复合组)和白纹伊蚊出现在三种栖息地中,而其他种类仅在一两种栖息地中滋生。地面水池和家用容器中记录的蚊虫种类最多,其次是排水沟/露天排水渠。树洞/叶腋是最不受青睐的栖息地,出现的蚊虫种类最少。然而,统计分析显示五种栖息地中蚊虫种类的出现情况没有显著差异。这些栖息地能够支持作为城市黄热病、淋巴丝虫病和疟疾已知传播媒介的伊蚊、库蚊和按蚊的滋生,这表明阿贝奥库塔市的居民面临蚊媒疾病的风险。重要的是要让该市居民了解导致蚊虫滋生的环境因素,并且政府应制定适当的卫生措施以减少蚊虫滋生地。
