目的：了解垃圾容器内垃圾残渣的蝇类滋生情况，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；采用化学防制方法，观察控制效果。结果：垃圾桶内的垃圾残渣中普遍有蝇幼虫滋生，平均滋生率79.19％；其中残渣厚度在3cm以上的，滋生率高达86．53％；优势蝇种为家蝇，占74．80％。采用降低杀虫剂使用浓度与增加使用量，并保持有效成分含量不变的处理方法，能显著提高杀灭蝇蛆的效果；经马拉硫磷、凯素灵、氯菊酯和氯菊酯与马拉硫磷混合液等4组药物的灭效试验，认为氯菊酯（0．02％）与马拉硫磷（0．15％）混合液对控制垃圾残渣内的蝇类滋生，具有较理想的效果。结论：垃圾日产日清后，垃圾容器内的垃圾残渣成为蝇类主要滋生场所，应列为防制的重点。
Objective: To understand the breeding of flies in trash containers and explore the effective measures to control fly larvae. Methods: The visual 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 commonly found in trash cans, with an average breeding rate of 79.19%. Among them, the residue with the thickness of 3cm or more had a high rate of 86.53%. The dominant flies were housefly, accounting for 74.80%. The use of pesticides to reduce the concentration and increase the use of the amount of active ingredients and maintain the same content of the treatment can significantly increase the killing maggot effect; by malathion, Kai Suling, permethrin and permethrin And malathion mixture of four groups of drugs such as the killing test, that the permethrin (0.02%) and malathion (0.15%) mixed solution to control flies within the garbage residue breeding, with The ideal effect. CONCLUSION: After the rubbish is produced daily, the rubbish residue inside the rubbish container becomes the main breeding place for flies, which should be listed as the focus of prevention and control.
