摘要
目的了解和掌握辽宁省蚊虫密度、季节消长等变化规律,为蚊虫防制和蚊媒传染病的风险评估、预警及防控提供科学依据。方法 2014-2018年每年的5-10月,在辽宁省城区(居民区、公园和医院)和农村(农户和牲畜棚)5类生境,采用诱蚊灯法进行蚊密度监测,分析蚊种构成、密度及季节消长趋势。结果 2014-2018年辽宁全省共布放诱蚊灯7 000盏,捕获蚊虫275 736只,蚊虫种群构成中淡色库蚊、中华按蚊、三带喙库蚊居前3位,分别占捕获总数的24.59%、21.01%和19.06%。蚊虫总密度为19.70只/(灯·h),2014-2018年蚊虫密度分别为16.75、26.05、15.83、20.23和19.65只/(灯·h),其中不同生境蚊虫密度以牲畜棚最高,达72.60只/(灯·h),医院最低,为2.40只/(灯·h)。蚊虫总体的季节消长情况呈单峰型曲线,各年度蚊虫密度高峰均出现在8月上旬或8月下旬。结论辽宁省蚊虫防制以牲畜棚和农户为重点控制场所,5-10月是控制蚊虫的关键时间段。建议各监测点继续加强媒介蚊虫监测工作,为蚊虫及蚊媒传染病可持续控制提供依据。
Objective To investigate the seasonal fluctuation of mosquito density in Liaoning province, China, and to provide a scientific basis for mosquito control and risk assessment, early warning, and prevention and control of mosquito-borne diseases. Methods From 2014 to 2018, mosquito density was monitored by the lamp trapping method from May to October in five mosquito habitats within urban areas(residential areas, parks, and hospitals) and rural areas(rural households and livestock sheds) of Liaoning province. Mosquito composition, density, and seasonal fluctuation were analyzed. Results From 2014 to 2018, a total of 7 000 mosquito traps were set up in Liaoning province and 275 736 mosquitoes were caught. In terms of mosquito species composition, Culex pipiens pallens, Anopheles sinensis, and Cx.tritaeniorhynchus were the top three, accounting for 24.59%, 21.01%, and 19.06% of the total mosquito counts,respectively. The overall mosquito density was 19.70 mosquitoes/lamp·hour. From 2014 to 2018, the mosquito density in each year was 16.75, 26.05, 15.83, 20.23, and 19.65 mosquitoes/lamp·hour, respectively. In terms of mosquito habitats,livestock sheds had the highest mosquito density(72.60 mosquitoes/lamp·hour), while hospitals had the lowest(2.40 mosquitoes/lamp·hour). In each year, the overall mosquito density fluctuated seasonally with a single peak in early or late August. Conclusion For mosquito control in Liaoning province, livestock sheds and rural households are the key places and the May to October period is the key time. Vector mosquito surveillance at each surveillance site should continue to be strengthened to provide a basis for the sustainable control of mosquitoes and mosquito-borne infectious diseases.
