Abstract:

Objective To compare the effectiveness of the labor-hour method and the light trap method to mosquitoes, providing the basis for development of scientific and standard mosquito monitoring. Methods The study was conducted in Ningbo, where adult mosquitoes were monitored using the light trap method on a monthly basis to identify the composition and seasonal dynamics of mosquitoes. The resulting data were compared with the monitoring results from 2006 through 2008 based on the labor hour method. Results According to the labor-hour monitoring results, Culex pipiens pallens was the predominant indoor species in the residential areas of the city from 2006 to 2008, accounting for 99.17% of total mosquitoes. Aedes albopictus, Anopheles sinensis and Cx. tritaeniorhynchus accounted for 0.49%, 0.20% and 0.13%, respectively. The light trap monitoring in residential areas showed that Cx. pipiens pallens accounted for 81.55% of the total number, while Cx. tritaeniorhynchus, An. sinensis and Ae. albopictus accounted for 13.43%, 2.31% and 1.97%, respectively. Conclusion Both kinds of approaches were useful in revealing the composition of predominant mosquito species in the region. Therefore, the light trap method, featuring ease of use and minimum man-made factors, is more suitable for long-term systematic monitoring.

摘要：

目的 比较人工小时法和灯诱法的诱蚊效果，为科学规范开展蚊虫监测提供理论依据。方法 选择宁波市为试点，每月采用灯诱法调查成蚊，观察蚊类组成及季节变化情况，与2006－2008年人工小时法监测结果相比较。结果 2006－2008年居民区室内人工小时法监测，淡色库蚊为优势种，占捕蚊总数的99.17%，白纹伊蚊、中华按蚊、三带喙库蚊分 别占0.49%、0.20%和0.13%。居民区灯诱法监测，淡色库蚊占捕蚊总数的81.55%，三带喙库蚊、中华按蚊、白纹伊蚊分别占 13.43%、2.31%和1.97%。结论 2种方法监测结果均能显示该地区优势蚊种构成情况，因而推广使用具有操作简单，人为影响因素小的灯诱法，认为其更适合长期系统监测。
