Abstract: Objective To investigate the distribution of mosquito populations in Chongqing, China, and to provide a basis for the development of mosquito control measures. Methods From August to October, 2018, eight districts/counties in Chongqing were selected according to their geographical locations for field investigation in both urban and rural areas. Mosquitoes were captured by trapping lamps, mosquito data were collected and descriptively analyzed by Excel 2010 and ArcGIS 10.60 softwares, and the rank sum test was used by SPSS 25.0 software for different mosquito species density in urban and rural areas. Results A total of 5 species of mosquitoes in 4 genera were collected, and the total mosquito density was 14.83 only/(lamp·hour). The urban mosquito density was 0.67 only/(lamp·hour), and the dominant species were Culex pipiens quinquefasciatus and Aedes albopictus; the rural mosquito density was 18.69 only/(lamp·hour), and the dominant species were Cx. tritaeniorhynchus and Armigeres subalbatus. Rongchang area had the highest total mosquito density, and the density of Cx. tritaeniorhynchus in rural areas was higher than that in urban areas (Z=-3.019, P=0.003). Conclusion The total mosquito density is relatively high in Chongqing, and appropriate mosquito control measures should be taken according to local conditions to prevent and control the occurrence of mosquito-borne diseases.

摘要： 目的 了解重庆市蚊虫种群分布情况，为制定蚊虫防制措施提供依据。方法 2018年8-10月按地理方位在重庆市选取8个区（县）作为调查点，分别在城区和农村地区开展调查，采用诱蚊灯法捕捉蚊虫，收集整理蚊虫数据并采用Excel 2010和ArcGIS 10.60软件进行描述性分析，针对城区和农村地区不同蚊种密度采用SPSS 25.0软件进行秩和检验分析。结果 共采集蚊虫4属5种，密度为14.83只/（灯·h），城区蚊虫密度为0.67只/（灯·h），优势种为致倦库蚊和白纹伊蚊，农村地区蚊虫密度为18.69只/（灯·h），优势种为三带喙库蚊和骚扰阿蚊。荣昌地区总蚊密度最高，农村地区三带喙库蚊密度高于城区（Z=-3.019，P=0.003）。结论 重庆总体蚊密度较高，应因地制宜采取适当的蚊虫防制措施，防控蚊媒病的发生。
