目的 调查上海市杨浦区地下车库蚊种构成，了解种群形成原因及趋势。方法 2013年12月至2014年11月从不同封闭类型的地下车库集水井中采集蚊幼虫，饲养至成蚊后制作雄蚊尾器标本进行鉴定。结果 全封闭小空间型车库内均为骚扰库蚊；全封闭大空间型车库内骚扰库蚊占该车库有效标本数的54.09%（119/220），淡色库蚊占27.27%（60/220）；半封闭型车库内淡色库蚊占该车库有效标本数的54.23%（141/260），致倦库蚊占35.77%（93/260）。结论 上海市地处中国淡色库蚊与致倦库蚊种群交叉地带，两者同时存在，亦存在中间过渡类型，该地区蚊种构成复杂，需密切监测以控制蚊媒传染病。

Objective To investigate on mosquito species of underground garage, and to make a preliminary research on the reason and tendency of them. Methods Gathered the mosquito larva from different kinds of underground garage in December of 2013 to November of 2014, then made some specimens of male mosquito genitalia after they were reared to adults. Results Culex pipiens molestus were the only species in the closed and small underground garage. Culex pipiens molestus accounted for 54.09%(119/220) of the Cx. pipiens complex in the closed and large underground garage, while Cx. pipiens pallens accounted for 27.27%(60/220). Culex pipiens pallens accounted for 54.23%(141/260) of the Cx. pipiens complex in the half-closed underground garage, while Cx. pipiens quinquefasciatus accounted for 35.77%(93/260). Conclusion Shanghai is located in the area with both Cx. pipiens pallens and Cx. pipiens quinquefasciatus, and it's complicated of mosquito species. It's necessary to monitor tightly in order to control the mosquito-borne infectious diseases.
