目的了解垃圾容器底垃圾残渣的蝇类孳生情况,探讨控制蝇蛆的有效措施。方法采用目测法,观察活蛆存在情况,进行分类鉴定;采用化学防治方法,观察控制效果。结果垃圾桶底的垃圾残渣中普遍有蝇幼虫孳生,平均孳生率为79.19%;其中残渣厚度在3 cm以上的,孳生率高达86.53%;优势蝇种为家蝇,占74.80%。结论垃圾日产日清后,垃圾容器底的垃圾残渣成为蝇类主要孳生场所,应列为防治的重点。
Objective To understand the breeding of flies in trash residue at the bottom of trash containers and to explore effective measures to control fly larvae. Methods The visual observation method was used to observe the existence of live maggots, and the classification was identified. The chemical control methods were used to observe the control effects. Results The larvae of fly larvae were generally found in garbage residues at the bottom of trash bins, with an average breeding rate of 79.19%. Residues with a thickness of 3 cm or more showed a breeding rate of 86.53%. Dominant flies were domestic flies, accounting for 74.80%. Conclusion After the rubbish is produced daily, the rubbish residue at the bottom of the rubbish container has become the main breeding place for flies and should be listed as the focus of prevention and control.
