目的 对云南省昆明市五华区的蚊虫进行调查，为蚊媒监测及科学制定蚊类防制措施提供依据。方法 2016年7-10月根据五华区海拔数据分为高（>2 200 m）、中（1 800~2 200 m）、低（<1 800 m）3个层次，不同海拔高度各选1个调查点，东、西、南、北方位各选1个调查点，中方位选择3个调查点，采用诱蚊灯通宵捕蚊和人饵诱捕法监测蚊密度，对所捕获蚊类进行鉴定分类和统计。结果 共捕获蚊虫4 578只，隶属于4属12种，优势蚊种为致倦库蚊（2 188/4 578，47.79%），7月捕获最多（1 479/4 578，32.31%）；诱蚊灯法监测蚊密度，以7月最高，达7.70只（灯/·h）；厂口农贸市场牛棚捕获蚊虫数量最多，占捕获总数的18.50%（847/4 578）。结论 五华区存在传播流行性乙型脑炎、疟疾、登革热等虫媒传染病的传播媒介，极易引起蚊媒传染病的暴发流行，应制定科学合理的蚊类防制措施。
Objective Mosquitoes in Wuhua district of Kunming city, Yunnan province were investigated to provide evidence for mosquito monitoring and scientific control measures. Methods During July to October 2016, three altitudes, high(>2 200 m), intermediate(1 800-2 200 m), and low(<1 800 m) were selected, and one survey point was set up at each altitude. Seven sampling stations were established at the East, West, South, and North of the survey point. Mosquito collection was conducted by lure light trap and human baiting overnight. Collections were identified, data were tabulated and analyzed. Results A total of 4 578 mosquitoes were captured, belonging to 4 genera and 12 species. The catches in July was most abundant(1 479/4 578, 32.31%), and the light trapping was more efficient(7.70 per lamp hour). Culex pipiens quinquefasciatus was the predominant species(2 188/4 578, 47.79%). The most productive site was the produce market, collecting 847 mosquitoes, accounting for 18.50% of the total. Conclusion The mosquitoes that vector epidemic encephalitis B, malaria, dengue fever and other insect-borne diseases were identified at Wuhua district, Kunming. Control measures should be proposed and implemented.
