Abstract：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 106 841 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.
