2018年云南省蝇类监测

Surveillance on flies in Yunnan Province in 2018

目的了解云南省各类型生态环境蝇类的种类、密度及季节消长规律,为有效防控蝇类提供参考。方法采用笼诱法进行蝇类监测。结果全省捕获蝇类总密度为3.22只/笼,各监测点捕获蝇类密度以保山最高,为8.00只/笼;玉溪最低,为0.67只/笼。昆明、昭通、红河和曲靖分别为4.14、3.71、2.91和1.11只/笼。全省优势蝇种为家蝇、市蝇、麻蝇,共占蝇类捕获总数的94.72%;不同生境以居民区蝇密度最高,为3.76只/笼;蝇密度高峰期出现在6月,主要蝇种密度的高峰期多出现在5—6月。结论家蝇为优势蝇种,5—6月为蝇类密度高峰期,应注意在高峰期前采取防治措施。

Objective To understand the species,population density,and seasonality of flies in various ecological environments in Yunnan Province and provide reference for prevention and control of flies.Methods The cage trapping method was employed for the surveillance.Results The density of flies captured in the whole province was 3.22 insects per cage.The highest density,8.00 insects per cage,was found in Baoshan,while the lowest density,0.67 insects per cage,was found in Yuxi.The densities were 4.14,3.71,2.91 and 1.11 insects per cage respectively in Kunming,Zhaotong,Honghe and Qujing.Musca domestica,Musca sorbens and Sarcophagidae were the dominant fly species in the province,accounting for 94.72%of the total captured flies.The density in the residential areas was 3.76 insects per cage,highest among habitats.The fly density peaked in June,and the main species peaked in May and June.Conclusion Musca domestica was the dominant species,and the peak of fly densities occurred in May and June.Control measures should be implemented before the peak period.
