目的观察日落前后蚊、蠓种群动态。方法采用网捕法,按一定线路,不同高度,于日落前后进行定时采集。结果采集到的蠓数量最多,有7属1039只,以库蠓属为主;蚊虫为2属2种,共计53只。活动高峰多在日落后1h。结论初步了解翁昂乡民居附近日落前后蚊、蠓的种类组成和动态分布。

Objective To determine the population dynamics of mosquitoes and midges before and after sunset. Methods Net traps were set along certain locations at varying heights to capture the insects before and after sunset. Results Most of the captures were midges, amounting to 1039 of 7 genera, dominated by the genus Culicoides. The collected mosquitoes were of 2 species under 2 genera, totaling 53. The activity peak of the insects was approximately 1 hour after sunset. Conclusion The species composition and dynamics of mosquitoes and midges around the residential areas of Weng＇ang village before and after sunset were generally clarified.
