驻济某部营区蝇类种群密度调查分析

目的摸清某部营区蝇类种群密度,考核灭蝇措施效果。方法外环境重点场所每半月灭蝇,室内滞留喷洒与物理灭蝇法相结合。蝇密度考核室外用捕蝇笼诱法,室内采用定面积计数法。结果 27笼捕获蝇687只,鉴定为10属14种,其中家蝇占捕获总数的61.87%,为营区蝇类优势种;蝇密度季节消长呈单峰型,7~9月为蝇密度高峰期;食堂、生活服务中心、机关办公室等场所通过滞留喷洒并结合物理灭蝇法,蝇密度均处于较低水平,机关办公室逐月检查均未发现蝇。结论在城乡结合部,营区外蝇密度受环境影响,控制难度较大,但室内通过采取有效灭蝇措施可将其控制在无害水平。

Flies population density investigation analysis in a PLA unit camp of Jinan

Objective To study the flies’ population density in a PLA unit camp,and evaluate effectiveness of fly control. Methods Killing- fly was carried out in outside sites environment every half- month. spray and physical killing fly method were combined and used in room; area of counting method was used in the room.Results 687 flies were captured by 27 cages,10 genus and 14 strains were identified,Muscadomestica is61. 87% in all flies and is the dominance strain in unit camp; Seasonal fluctuation of fly density present unimodel type,peak season of fly density is in July- September; Residual spray and physical killing fly method were combined in canteen,living service center and office of department,et al,fly density were on the lower level,there is no fly in department office by monthly checking. Conclusions In the rural- urban fringe zone,fly density was affected by the environment outside the unit camp,it is difficult to control,but it is viable to control fly density in a harmless level by taking effective methods in room.
