诱蚊灯法与人工小时法捕蚊效果比较研究

Comparative study on mosquito-trapping effects of lamp trapping method and labor hour method

目的比较诱蚊灯法和人工小时法2种捕蚊方法的现场捕蚊效果,为开展科学规范的蚊虫调查或监测方法提供参考。方法沿三峡库区按距离大坝远近不同选择3个点,同时使用2种捕蚊方法对居民区及其周围环境进行蚊虫种类及其构成调查。结果诱蚊灯法和人工小时法均能捕获库区的主要蚊种,但在蚊种构成上有差异,诱蚊灯法捕获的三带喙库蚊数量大于人工小时法,而人工小时法捕获的骚扰阿蚊数量远大于诱蚊灯法;诱蚊灯法适用范围比人工小时法更广泛,可应用于林地、稻田等没有空间限制的环境。结论 2种蚊虫采集方法分别具有不同的优势和劣势;在长期系统的调查或监测中,建议使用诱蚊灯法。

Objective To compare the mosquito-trapping effects of lamp trapping method and labor hour method,and to provide a reference for scientific and standard investigation and surveillance of mosquitoes.Methods Three sites were selected for study based on their different distances from the Three Gorge Dam in the Three Gorge Reservoir area.The mosquito species composition was investigated by lamp trapping method and labor hour method in the residential area and its surrounding area at each of the three sites.Results Both lamp trapping method and labor hour method could be used for successfully trapping the main species of mosquitoes in the Three Gorge Reservoir area,but with difference in the species composition of captured mosquitoes.More Culex tritaeniorhynchus was captured with lamp trapping method than with labor hour method,while much more Armigeres subalbatus was captured with labor hour method than with lamp trapping method.The application scope of lamp trapping method was wider than that of labor hour method.The lamp trapping method could be applied in the places without space limitation,such as forest and rice field.Conclusion Each mosquito trapping method has its own advantages and disadvantages.Lamp trapping method is recommended in the long-time investigation and surveillance of mosquitoes.
