我們应該抓紧及早消灭越冬蝇蛹,以收到早春消灭一个蝇蛹等于夏秋消灭千万个蒼蝇的效果。蝇蛹大都在厕所、粪坑(缸)、粪肥堆、垃圾堆、猪圈、牛棚、馬厩等处及其附近松泥土中、以及其他蒼蝇常集聚的地方。必須有計划地根据不同对象、具体情况,分別采取有效措施来消灭蝇蛹。
We should pay close attention to the early elimination of wintering pupae, in order to receive the effect of eliminating one fly pupae in early spring, equal to eliminating 10 million flies in summer and autumn. Fly pupae mostly in latrines, cesspools (tanks), manure piles, trash, pigsty, cow sheds, stables and other places in the vicinity of the soil and other flies often gather place. Must be planned according to different objects, the specific circumstances, respectively, to take effective measures to eliminate fly pupae.
