目的 利用全自动静电吸附诱蚊监测灯(静电诱蚊灯)监测蚊虫,为开展科学规范的蚊虫调查和监测方法提供参考。方法 于2009-2013年选择嘉定区所有13个乡镇,利用静电诱蚊灯监测蚊虫密度,同时选取1个监测点比较静电诱蚊灯和吸入式诱蚊灯两种方法监测蚊虫密度、种类的差异及蚊种构成比和季节消长趋势的相关性。结果 静电诱蚊灯采用253.7 nm紫外线光谱,对本地区常见蚊种引诱率较强,与吸入式诱蚊灯(波长360 nm)相比,静电诱蚊灯诱获蚊虫数量为吸入式诱蚊灯的2.12倍;且对三带喙库蚊、中华按蚊的引诱效果较好,对其他昆虫引诱率低,虫体完整。利用静电诱蚊灯自动监测6 h的平均密度比全夜监测12 h的结果高71.93%,差异有统计学意义(t=-2.837,P=0.016),蚊虫活动集中在上半夜。结论 静电诱蚊灯在波长、监测时间、自动性、防雨防潮、标本麻醉及虫体损伤等方面有新改进,符合《全国病媒生物监测方案》要求,可用于蚊虫监测、虫相调查、流行病学调查和疫点处理等。

Objective To evaluate the automatic electrostatic adsorption mosquito monitoring lamp (hereinafter referred to as electrostatic mosquito lamp) in mosquito monitoring, and to provide a reference for scientific and standard investigation and surveillance of mosquitoes. Methods Choose all 13 towns of Jiading district, for a period of 5 years, using electrostatic mosquito lamp to monitor mosquito populations at the same time, choose 1 place to compare electrostatic mosquito lamp and suction trap as function of mosquito density, species, seasonal trend. Results The electrostatic mosquito lamp using 253.7 nm UV spectrum, the attraction rate is better on the local mosquitoes, compare with the suction type mosquito lamp (wavelength 360 nm), the number of captured mosquitos by electrostatic mosquito light trap mosquitoes was 2.12 times higher than those by suction type mosquito lamp; and the attractive effect was better especially on Culex tritaeniorhynchus and Anopheles hyrcanus sinensis, the specimen was intact, and less attractive to other insects, Electrostatic mosquito lamp automatically monitors for 6 h, the average density was 71.93% higher than monitoring all night of 12 h (t=-2.837, P=0.016). Conclusion Electrostatic mosquito lamp has a new breakthrough in wavelength, time monitoring, automatic performance, use in the rains, specimen anesthesia, minimized specimen damage, which comply with the "Regulations of national vector surveillance program" requirements. This tool is useful in mosquito fauna survey, epidemiological investigation and others.
