目的了解海淀区奥运会比赛场馆及周边的蚊蝇种类、密度和季节消长情况,为奥运会的病媒生物防治工作提供科学依据。方法蚊虫密度监测采用CO2灯诱捕法;蝇类密度监测采用天幕式捕蝇笼诱捕法。结果在海淀区奥运会比赛场馆共捕获蚊972只,平均密度为2.89只/(灯.h);捕获蝇5 156只,平均密度为30.69只/(笼.d)。结论根据监测结果,海淀区奥运场馆及周边的蚊虫密度在8月上旬密度较高,蝇类密度在8月出现降低,可根据蚊蝇消长规律采取措施,做好杀灭工作。
Objective To understand the species, density and seasonal fluctuation of mosquitoes and flies in venues and surrounding areas of the Olympic Games in Haidian District, and to provide a scientific basis for vector control of the Olympic Games. Methods The density of mosquitoes was monitored by CO2 lamp trapping method. The flies density was monitored by fly-trap traps. Results A total of 972 mosquitoes were captured at the Olympic Games venues in Haidian. The average density was 2.89 / (lamp .h). There were 5 156 flies caught, with an average density of 30.69 / (cage.d). Conclusion According to the monitoring results, the density of mosquitoes in the Olympic venues and the surrounding areas in Haidian was higher in early August and the density of flies decreased in August. Measures can be taken according to the growth and decline of mosquitoes and flies to kill them.
