猪粪是蝇类重要孳生物质。在农村和近郊饲养业中,猪粪量更是面广量大,所以要控制猪粪中的蝇类孳生是一项艰巨而复杂的工作。为此希望能找到简便易行而有效,又能适应农村物质条件的控制猪粪中的蝇类孳生的方法。我们于1983年9月间,选择一个猪粪中家蝇孳生密度严重又未采取其它防制蝇类措施的延安饲养场进行了本实验。
Pig manure is an important breeding material for flies. In the rural and suburban farming industry, the amount of pig manure is more and more large, so to control flies in pig manure breeding is a difficult and complex task. In this regard, I hope to find a way to control fly breeding in swine manure that is simple, effective and adaptable to rural material conditions. In September 1983, we conducted a pilot study in Yan’an, a farmer that chose to have a very high density of housefly in pig manure and did not take any other measures to control flies.
