2018—2020年绵阳市城区蝇类监测分析

Surveillance and analysis of flies in urban areas of Mianyang from 2018 to 2020

目的 了解绵阳市城区蝇类密度及季节消长规律,为有效防治蝇类提供技术支撑。方法 采用诱蝇笼法进行蝇类监测。结果 绵阳市城区2018—2020年共捕获蝇类286只,属3科5属8种,平均密度为0.71只/笼;各年度平均密度分别为0.62、0、90和0.60只/笼;优势蝇种为家蝇、厩腐蝇、丝光绿蝇,分别占39.51%、23.78%、18.53%;蝇密度高峰期在6—8月,绿化带蝇密度最高。结论 绵阳市城区蝇类密度均处于较低水平,6—8月是蝇类防治关键时期,公园绿化带是蝇类防治重点场所。

Objective To understand the fly density and seasonal fluctuation in the urban areas of Mianyang, and to provide technical support for the effective control of flies.Methods Fly density was monitored with cage trap method.Results From 2018 to 2020,a total of 286 flies were captured in Mianyang City, and classified into 8 species, 5 genera, 3 families.The average density was 0.71 insects per cage.The average annual densities were 0.62,0.90 and 0.60 insects per cage respectively in the three years.The dominant species were Musca Domestica,Musca Steleophaga and Lucilia Sericata,accounting for 39.51%,23.78% and 18.53% respectively.The peak of fly density was from June to August, and the highest density was found in greenbelt among different habitats.Conclusion The density of flies in the urban areas of Mianyang City was at a low level.The key period for fly control was from June to August, and the green belt of the park was the important place for fly control.
