摘要
目的 了解成都双流国际机场蝇类密度、种群分布和季节消长情况。方法 采用笔诱法。结果 全年共捕获蝇类9822只。经实验室分类鉴定分属于有瓣类5科9亚科22种,无瓣类果蝇1种,共23种。其中巨尾阿丽蝇占30.13％、丝光绿蝇占28.71％、厕蝇占13.08％,以上3种为优势种。蝇密度季节消长从2月出现,4月密度较高,5月达到高峰(12.3只/笼1小时),到6、7月蝇密度显著下降比5月份下降6～8倍,到8月略有回升,从9月起又逐渐下降,到翌年1月密度为0,表明蝇进入越冬期。
Objective To realize the species, the density, and the season ebb and flow of flies in Chengdu Shuangliu International Airport. Methods The Cage - Captuer method was adopted. Results 9822 of files were captured in all year.They were resided respectively in 5 families,9 sub - families genera and 22 species in Calyptratae and 1 species (drosophila) in Acalyptratae, total 23 species. Species cpmposing of flies captured: Aldrichina graham (30. 13%), Lucilia sericata (28. 71 %), fanniidae (13. 08 % ) . These are preponderant species. The ebb and flow of fiy density: flies appeared in Februay, flies density noisted in April,and reached the climax in May(12.3%/cage per hour) .The density descended since June and July, The density noisted again in August and descended gradually again in September. The density was zero in January next year.This indicates that flies were living through the winter.
