摘　　要：目的掌握兰州市主要城区蚊虫种群构成、不同生境下蚊虫密度及季节消长趋势,为防控工作提供科学依据。方法采用诱蚊灯法开展调查。对2012—2020年兰州市蚊密度监测数据进行整理分析。结果2012—2020年共捕获蚊虫10010只,蚊虫总密度为449只/(灯·h)。其中淡色库蚊为优势种群,占蚊虫总数的9847%,其次是三带喙库蚊(043%);不同生境以牲畜棚蚊密度最高942只/(灯·h),医院最低1.69只/(灯·h);牲畜棚、公园和农户蚊种较丰富;2017年总体蚊密度最高,为46只/(灯·h);9年捕获蚊虫总密度季节消长趋势呈单峰曲线,最高峰在7—8月。结论2012—2020年兰州市蚊密度总体控制较好,应继续加强以环境治理为基础的综合防蚊灭蚊工作。Objective To understand mosquito population composition,mosquito density and seasonal trend in different habitats in the main areas of Lanzhou,and to provide scientific basis for the prevention and control of mosquito.Methods Lamp trap method was adopted for the surveiliance.The surveillance data in Lanzhou City from 2012 to 2020 were analyzed.Results A total of 10010 mosquitoes were captured from 2012 to 2020,with the density as 449 mosquitoes per lamp per hour.Culex pipiens pallens was the dominant species accounting for 9847%,followed by Culex tritaeniorhynchus(043%).In different habitats,the highest density of mosquitoes was 942 mosquitoes/(lamp·hour)in livestock sheds and the lowest was 169 mosquitoes/(lamp·hour)in hospitals.Mosquito species were abundant in livestock sheds,parks and farmers The overall mosquito density in 2017 was highest at 46 mosquitoes/(lamp·hour).The seasonal trend of the total density of mosquitoes in 9 years showed a unimodal curve,with the peak between July and August.Conclusion The mosquito density was controlled well in Lanzhou from 2012 to 2020.The integrated mosquito control with environmental management as the basis should be strengthened.
