目的使用卫生杀虫剂控制和降低城市垃圾中转站苍蝇密度。方法滞留喷洒杀虫剂,用粘蝇条和强迫接触法考核灭蝇效果。结果通过3个月的灭效观察,其效果不一,垃圾中转站环境好的蝇密度有效控制期可在90 d以上,条件差的仅有15 d左右。结论单独使用卫生杀虫剂,不能控制垃圾中转站的密度,应该积极采取综合防治措施和多种灭蝇方法,有效控制和降低城市垃圾中转站苍蝇的密度。
Purpose To use hygienic insecticides to control and reduce the flies density at the urban refuse transfer station. Methods Insecticides were stranded and sprayed, and the effect of fly-killing was evaluated with sticky fly and forced contact method. The results showed that the effective control period of fly density in the environment of the refuse transfer station could be over 90 days, with the difference of only about 15 days. Conclusion The use of sanitation insecticides alone can not control the density of refuse transfer stations. Therefore, comprehensive prevention and control measures and a variety of fly-killing methods should be actively adopted to effectively control and reduce the density of flies in urban refuse transfer stations.
