摘　　要：目的了解2017—2020年浙江省温州市蝇类密度及季节消长规律,为蝇类防制提供科学依据。方法采用笼诱法,于2017—2020年每年的4—11月在农贸市场、餐饮外环境、绿化带和居民区4种生境进行监测。结果2017—2020年温州市共监测到蝇类4科8属13种7197只,主要蝇种为家蝇、麻蝇、市蝇、丝光绿蝇、大头金蝇和铜绿蝇;季节消长以6—9月为密度高峰月。2017年蝇密度最高,为2.99只/笼;2018年蝇密度最低,为1.93只/笼。在农贸市场、餐饮外环境、绿化带和居民区4种生境中,蝇种最多的是绿化带为13种,但蝇密度最高的是农贸市场为3.06只/笼。结论温州市蝇类种群和数量丰富;家蝇、麻蝇、市蝇、丝光绿蝇、大头金蝇和铜绿蝇等优势种群需要重点控制;农贸市场是关键控制场所,6—9月是蝇类及蝇传疾病防控的重要节点。Objective To monitor the density and seasonal fluctuation of flies in Wenzhou,Zhejiang province,and provide scientific evidence for fly control.Methods Cage traps were set up in the following four types of habitats:farm produce markets,catering external environment,greenbelts and residential areas.Results A total of 7197 flies,belonging to 4 families,8 genera,and 13 species,were captured from 2017 to 2020.The predominant species were Musca domestica,Sarcophagidae,Musca sorbens,Lucilia sericata,Chrysomya megacephala and Lucilia cuprina.The annual density peak was during June-September.The highest density was 2.99 flies/cage in 2017,and the lowest population density was 1.93 flies/cage in 2018.In the four types of habitats,greenbelts had the highest fly diversity,where 13 species were found,and the highest fly density was found in farm produce markets with an average of 3.06 flies/cage.Conclusion The populations of calyptrate flies were abundant in Wenzhou.The predominant species,such as Musca domestica,Sarcophagidae,Musca sorbens,and Lucilia sericata,should be the focus of fly control.Primary control measures should be taken in farm produce markets and during June-September for the prevention and control of fly-transmitted diseases.
