上海市杨浦区4种不同生境蝇类种群及季节消长

目的了解杨浦区4种生境蝇类种群及季节消长情况,为蝇类防制提供科学依据。方法采用笼诱法,于2010-2013年每年的3-11月在大型绿地（公园）、中小饭店周边绿地、居民小区和农贸市场4种生境进行监测。结果 2010-2013年共捕获蝇类5科25属39种1588只,优势种为厩腐蝇、丝光绿蝇、巨尾阿丽蝇、横带花蝇、大头金蝇、狭额腐蝇;季节消长曲线呈现6月和9月双高峰,2010年密度最低。在大型绿地、农贸市场、中小饭店周边、居民小区4种生境中,蝇类种群最多的是大型绿地为32种,密度最高的是农贸市场为4.70只/（笼·d）。结论杨浦区有较好的蝇类生境,蝇类种群丰富;厩腐蝇、丝光绿蝇、巨尾阿丽蝇等优势种群需要重点控制;农贸市场是关键控制场所,6及9月前后是控制蝇类及蝇传疾病防控的两个重要时间节点。

Seasonality of calyptrate flies in four types of habitats in Yangpu district,Shanghai, China

Objective To monitor the species composition and seasonality of calyptrate flies in four types of habitats in Yangpu district, Shanghai, China, and to provide a scientific strategy for fly control. Methods Cage traps were set up in the following four types of habitats： large-scale greenbehs （parks）, greenbehs around restaurants, residential areas, and farm produce markets. Results A total of 1588 flies, belonging to 5 families, 25 genera, and 39 species, were captured from 2010 to 2013. The predominant strains were Muscina stabulans, Lucilia sericata, Aldrichina grahami, Anothomyia illocata, Chrysomya megacephala, and Muscina angustifrons. The seasonality showed peaks in June and September and the lowest population density in 2010. In the four types of habitats, the large-scale greenbehs showed the highest population diversity： 32 species, and the highest density was found in the farm produce markets with an average of 4.70 flies/cage, day. Conclusion The populations of calyptrate flies are abundant in habitats of Yangpu district, Shanghai. The predominant populations such as M. stabulans, L. sericata, and A. grahami should be the focus of fly control. Primary control measures should be taken in farm produce markets, and in June and September as the key time points for the prevention and control of fly-transmitted diseases.
