昆山口岸蝇类本底调查报告

A Baseline Survey on Flies at Kunshan Port

〔目的〕掌握昆山口岸蝇类本底情况,为开展蝇类防制和口岸监督工作提供依据。〔方法〕从2006年3—12月采用笼诱法对昆山口岸蝇类的种群组成、季节消长情况进行调查。〔结果〕本次调查共捕获蝇类21754只,经鉴定隶属4科12属15种,其中大头金蝇为优势种,占捕蝇总数的69.49%,其次为丝光绿蝇和黑尾黑麻蝇,分别占捕蝇总数的19.26%和2.63%,不同调查点的蝇类种群构成不完全相同。蝇密度在6月份和10月份形成2个高峰,分别为381.83只/笼·日和561.42只/笼·日。〔结论〕本次调查基本掌握昆山口岸蝇类本底情况,为进一步开展蝇类防制工作提供了科学依据。

Objective To master the baseline of the flies at Kunshan port, and to provide evidences for prevention and surveillance flies. Method From March to December in 2006, the cages were used to collect the flies, meanwhile the population and seasonal growth and dechine was investigated. Result 21754 flies were captured and as identified as 4 families,12 genera, and 15 species. Chrysomyia megacephala was the dominant species, accounting for 69.49%, while Lucilia sericata and Helicophagella melanura were less than Chrysomyia megacephala, accounting for 19.26% and 2.63% respectively.The population formations varied from place to place. There were 2 peaks of fly density in June and October, the annual average density of fly was 381.83 flies per cage and 561.42 flies per cage respectively. Conclusion We have basically mastered the baseline of the flies at Kunshan port in this investigation and therefore could provide scientific guideline for further prevention and cure of fly.
