摘要
目的了解上海市黄浦区蚊虫种群、密度及其季节消长规律,为制定蚊虫防制措施提供科学依据。方法选取辖区内5个具有代表性的室内生态环境作为监测点,采用人工小时法,每年3—11月,按照每月3次的频率分别在上、中、下旬用电动吸蚊器各监测1次,每次每个点15 min。结果 2008—2015年共捕获蚊虫成虫677只,平均蚊虫密度为2.6只/(人·h),我区优势蚊种为淡色库蚊和白纹伊蚊。2008—2015年上海市黄浦区蚊密度每年的消长呈单峰型曲线,高峰值出现在2012—2014年。不同生态环境蚊虫密度由高到低依次为居民住宅区、公园、机关、学校宿舍。2008—2015年蚊虫密度逐月分析显示,蚊类在每年6—7月和9—10月有2个峰值出现。结论黄浦区优势蚊种主要为淡色库蚊和白纹伊蚊,每年6—7月和9—10月是蚊类出现的高峰时间。建议加强蚊虫高峰季节前的控制,加强对蚊虫及其传播疾病的长期监测、预警、控制对策和措施的研究。
Objective To determine mosquito species, density and seasonal changes District, Shanghai; and to provide scientific evidences for control strategies. Methods in Huangpu In total five representative indoor spots were selected. Mosquito monitoring was carried out using the labor hour method from March to November each year. Mosquitos were monitored by electric mosquito absorption three times each month, which was in early, middle and late of the months, and last for 15 minutes each time. Results In total there were 677 mosquito adults were captured from 2008 to 2015, with an average mosquito density of 2.6 / { pcs/h ~ site ）. Main mosquito species were Culex pipiens pallens and Aedes albopictus. The mosquito density increased first, peaked in 2012 - 2014 and declined afterward in the study period from 2008 to 2015. The density was the highest in residential areas, followed by parks, government buildings, and school dormitories. The monthly distribution of mosquito density in 2008 -2014 showed two peaks, which were in June to July and September to October, respectively. Conclusion The major mosquito species are Culex pipiens pallens and Aedes albopictus in Huangpu district. June to July and September to October are the two peak periods. Strengthened control measures are advised before the peak periods. Long-term monitoring, early warning and control measures of mosquito transmission need to be strengthened.
