首都机场口岸区域蝇种类及其季节消长情况调查

Fly Species and the Seasonal Abundamce at the-Area of Beijing Capital Airport

在首都机场地区用“天幕式诱蝇笼”法进行蝇类监测,共捕成蝇1699只,鉴定为4科。9亚科、18属、25种。均为北京地区常见种类。其中,麻蝇亚科种类占48.2％,与人类活动极为密切的家蝇占7.9％。蝇密度季节高峰在6～7月,季节消长与月平均温度显著相关(P<0.005)。机场地区蝇类防制重点是清除其孳生地,加强对家蝇的防治。

The survey of fly species and the seasonal abundance was carried out by means of 'Tian Mu Fly Traps' at the area of Beijing Capital Airport.25 species of the flies were sampled and they belonged to 18 genera (4 families). Most of them were common flies or synathropic flies distributed in Beijing. Flies of Sarcophaginae took the dominant position for 48. 2% ,houseflies (Musca domestica) which was most closely to human activities only for 7.9% by the sampling means. The seasonal abundance appeared in Jun. to Jul. and the fluctuations depended on temerature (p<0. 005).The survey showed that the keys of the fly control at the area should consentrat to the enviromental management and eliminate housefly infections indoors.
