摘　　要：目的了解海南省海口市、文昌市、定安县、屯昌县及临高县按蚊的分布现状。方法采用牛帐法于2011年4～5月在这5市县的山区、丘陵及平原三类环境中选取15个村庄进行调查。结果共捕获按蚊13种2 939只,其中嵌斑按蚊所占比例最高,达58.9%(1 731/2 939),其次为中华按蚊,达26.0%(761/2 939)。主要媒介微小按蚊仅在屯昌2个调查点捕获;另外在海口演丰镇捕获嗜人按蚊。结论中华按蚊及嵌斑按蚊是我省主要按蚊种类;微小按蚊的种群密度可能处于较低水平,分布点也可能在减少;但嗜人按蚊的分布点可能在扩大。Objective To understand the distribution of Anopheles in Haikou,Wenchang,Tunchang,Dingan and Lingao,Hainan Province.Methods From April to May 2011,Anopheline mosquitoes were collected by using cow bait.Three kinds of sites located in mountainous,hilly and（or）plain areas were chosen from each of the five counties（cities）for conducting the survey.Results A total of 2 827 Anopheline mosquitoes of 13 species were collected.An.tessellates and An.sinensis were the main species,the percentage of them were 60.3% and 26.5% respectively.An.minimus were only collected in mountainous areas in Tunchang County.And An.anthropophagus was captured in Yanfeng,Haikou.Conclusion An.tessellatus and An.sinensis were the main vector species in Hainan Province.The density of An.minimus in these sites might be low or sporadically distributed,but the distributiion of An.anthropophagus might be expanding.
