摘　　要：目的了解和掌握盘锦市蚊虫密度及季节消长情况,为蚊虫防治提供科学依据,并对蚊媒传染病提供预警信息。方法 2017—2019年每年5—10月采用诱蚊灯法对盘锦市城镇、农村5种不同环境蚊虫种类、密度进行监测。结果共捕获成蚊16 687只,计3属6种。中华按蚊和淡色库蚊为优势种,分别占所捕获蚊总数的43.94%和28.69%。不同年份主要蚊种构成比不相同。蚊虫总的密度为23.64只/(灯·h),其中2017年最高,为30.08只/(灯·h);2018年最低,为9.40只/(灯·h)。5种生境蚊虫密度以牲畜棚最高,达38.95只/(灯·h),其他生境、场所蚊虫密度以居民区>农户>公园>医院。蚊虫在5—10月均有活动,高峰一般在7—8月。结论初步掌握了盘锦市蚊虫密度、蚊虫种类、季节消长,为合理防治蚊虫和蚊媒传染病提供科学依据。Objective To learn and master the density and seasonal fluctuation of mosquitoes in Panjin,and provide scientific basis for mosquito control and early warning information for mosquito-borne diseases.Methods The species and density of mosquitoes in five different environments in towns and rural areas of Panjin were monitored by using the light trap method from May to October every year.Results From 2017 to 2019,a total of 16 687 mosquitoes belonging to 3 genera and 6 species were captured.Anopheles sinensis and Culex pipiens pallens were the dominant species,accounted for 43.94% and 28.69% respectively.The composition ratios of main mosquito species were different among years.The general average mosquito density was 23.64 insects per lamp in an hour,the highest was 30.08 insects per lamp in an hour in 2017,and the lowest was 9.40 insects per lamp in an hour in 2018. Among the five habitats investigated,the highest mosquito density,38.95 insects per lamp in an hour,was found in livestock sheds areas,followed by residential areas,living quarters of farmers,parks and hospitals.Mosquitoes were active from May to October,and the peak of mosquito activity usually occurred from July to August.Conclusion A preliminary understanding of mosquito density,species composition and seasonal fluctuation in Panjin has provided a scientific basis for reasonable control of mosquitoes and mosquito-borne diseases.
