2013—2017年鞍山市蚊虫监测分析

Mosquitoes surveillance in Anshan City from 2013 to 2017

目的掌握鞍山市蚊虫种群分布、季节消长等变化规律,为蚊虫防治提供依据。方法采用诱蚊灯法进行监测。结果 2013—2017年共捕获蚊虫72 470只,平均蚊密度为60.39只/(台·h)。2013年蚊虫密度最高,达160.83只/(台·h);2016年蚊虫密度最低,仅为24.97只/(台·h)。淡色库蚊为优势种,占捕蚊总数的74.38%。蚊虫密度季节消长曲线基本呈单峰型,蚊虫活动高峰期为7—9月。农村平均蚊密度为146.02只/(台·h),显著高于城区的3.31只/(台·h),牲畜棚与农户蚊密度分别为271.26和20.78只/(台·h)。结论鞍山市蚊虫主要防治对象是淡色库蚊,农户和牲畜棚是重点控制场所,应采取综合防治措施,降低蚊密度,有效防控蚊媒病的发生。

Objective To master the variation of mosquito population distribution and seasonal fluctuation in Anshan City,and provide basis for mosquito control. Methods The light traps were used to investigate mosquitoes. Results A total of 72 470 mosquitoes were captured from 2013 to 2017,with an average mosquito density of 60. 39 insects per light trap per hour. The highest mosquito density was 160. 83 insects per light trap per hour in 2013,and the lowest mosquito density was 24. 97 insects per light trap per hour in 2016. Culex pipiens pallens was the dominant species,accounting for 74. 38% of the total number of mosquitoes. The seasonal fluctuation curves of mosquito density were basically single peak from July to September. The average mosquito density was 146. 02 insects per light trap per hour in rural areas,significantly higher than that of 3. 31 insects per light trap per hour in the urban area,and the mosquito density in livestock sheds and peasant households were 271. 26 and 20. 78 insects per light trap per hour respectively. Conclusion Culex pipiens pallens was the main control object in Anshan City,and peasant household and livestock shed were the key control places. Comprehensive control measures should be taken to reduce the mosquito density and effectively prevent and control mosquito-borne diseases.
