摘　　要：目的分析2017-2021年四川省三带喙库蚊监测数据,掌握四川省三带喙库蚊的分布和种群动态变化情况,为防控工作提供科学依据.方法2017-2021年在四川省21个市州采用诱蚊灯法捕获不同生境中的三带喙库蚊.结果2017-2021年共捕获三带喙库蚊106841只,平均蚊密度为0.609只/(灯·h),农村监测点的平均蚊密度为1.407只/(灯·h),城市监测点的平均蚊密度为0.079只/(灯·h),农村平均蚊密度显著高于城市.四川东部城市的蚊密度明显高于西部城市.季节消长变化趋势呈单峰曲线,蚊密度的峰值月份为6-9月.2019年7月蚊密度最高,为3.476只/(灯·h).结论三带喙库蚊在四川省内分布广泛,在部分城市已成为优势蚊种,需要加强农村地区的三带喙库蚊防治工作.Objective To analyze the monitoring data of Culex tritaeniorhynchus in Sichuan Province from 2017 to 2021,and master the distribution and dynamic changes in the population of Culex tritaeniorhynchus,and provide scientific basis for the control work.Methods From 2017 to 2021,the light trap method was used to capture Culex tritaeniorhynchus in different habitats in 21 cities in Sichuan Province.Results From 2017 to 2021,a total of 106841 Culex tritaeniorhynchus adults were captured,with an average density of 0.609 mosquitoes/(lamp·h).The average mosquito density in the rural monitoring points was 1.407 mosquitoes/(lamp·h),higher than that of 0.079 mosquitoes/(lamp·h)in the urban monitoring points.The mosquito density in eastern cities of Sichuan was higher than that in western cities.The seasonal fluctuation trend showed a unimodal curve,with a peak from June to September.The highest mosquito density was 3.476 mosquitoes/(lamp·h),taking place in July 2019.Conclusion Culex tritaeniorhynchus is widely distributed in Sichuan Province,dominant in some cities.It is necessary to strengthen the control of Culex tritaeniorhynchus in rural areas.
