摘　　要：目的分析浙江省2021年不同地貌、生境蚊虫种类构成差异及4-11月蚊密度消长差异,为蚊虫控制和蚊媒传染病防制提供科学依据。方法2021年4-11月浙江省各县(市、区)选择居民区、公园、医院、农户和牲畜棚5类生境,采用诱蚊灯法每月上旬监测1次蚊虫。使用Excel 2021和SPSS 15.0软件对蚊虫种群和密度数据进行汇总与统计分析,描述性分析蚊密度消长差异,采用χ2检验分析不同地貌、生境蚊虫种类构成差异,蚊密度差异分析采用秩和检验。结果2021年浙江省共捕获雌蚊103669只,三带喙库蚊为优势蚊种,占53.40%;不同地貌区(χ^(2)=40563.669,P<0.001)、生境(χ^(2)=60457.931,P<0.001)蚊虫种类构成差异有统计学意义。除白纹伊蚊外,各蚊种种群数量均在牲畜棚生境中最多。2021年蚊密度为8.48只(/灯·夜),4-11月蚊密度消长曲线呈单峰型,6月达到密度高峰,为25.48只(/灯·夜)。结论浙江省不同地貌区、不同生境蚊虫种类构成存在差异,不同地貌区、不同生境的蚊密度消长趋势存在差异,各县(市、区)需要结合本地区蚊虫种群分布和密度消长情况制定不同的蚊虫监测方案与防控措施。Objective To investigate the differences in mosquito species composition and density fluctuation between different terrains and habitats in Zhejiang Province,China from April to November 2021,so as to provide a scientific reference for mosquito control and mosquito-borne disease prevention.Methods From April to November 2021,five types of habitats were selected in counties/cities/districts of Zhejiang Province,including residential areas,parks,hospitals,rural households,and livestock sheds,and mosquitoes were monitored once at the beginning of each month using the light trap method.Excel 2021 software was used to summarize the mosquito population and density data,and SPSS 15.0 software was used for statistical analysis.A descriptive analysis was employed to investigate the difference in mosquito density fluctuation.The Chi-square test was used for the difference in mosquito species composition between different terrains and between habitats.The rank-sum test was used for the difference in mosquito density.Results In 2021,103669 female adult mosquitoes were captured in Zhejiang Province,and Culex tritaeniorhynchus was the dominant mosquito species,accounting for 53.40%.There was a significant difference in the species composition of mosquito between different terrains(χ^(2)=40563.669,P<0.001)and between habitats(χ^(2)=60457.931,P<0.001).Apart from Aedes albopictus,other species of mosquitoes were numerous in livestock sheds.The mosquito density was 8.48 mosquitoes/light·night in Zhejiang Province in 2021,and the mosquito density fluctuation curve showed a single-peak from April to November,reaching a peak in June,which was 25.48 mosquitoes/light·night.Conclusions There exist significant differences in mosquito species composition and density fluctuation trend between different terrains and between habitats in Zhejiang Province.Counties/cities/districts in Zhejiang Province should develop different mosquito surveillance programs and preventive and control measures based on the distribution and density fluctuati
