To determine methoprene's effect on fly emergence from poultry manure, 18,000 8-wk.-old caged pullets were fed continuously 10 gm. of methoprene per ton of feed 42 days. Hatch mates (13,500) in an adjacent, similarly constructed and equipped house were fed untrated feed. Data on fly emergence were recorded twice a week after counting average numbers of flies in fly traps, in buckets of manure, and on fly strips and spot cards. Differences between average counts in the treated and control groups were significant by each of the four data-gathering methods. The methoprene reduced fly emergence by 77.0% in manure buckets, 65.5% in fly traps, but increased fly emergence 19.2% on fly strips, and 92.2% on spot cards. We attribute the increases in fly counts by the latter two counting methods in the treated house to migration of flies from adjacent untreated houses.
为确定烯虫酯对家蝇从鸡粪中羽化的影响，给18000只8周龄笼养小母鸡连续42天饲喂每吨饲料添加10克烯虫酯的饲料。相邻一栋构造和设备相似的鸡舍中13500只同批孵化的鸡则饲喂未添加烯虫酯的饲料。在对诱蝇器、粪桶以及粘蝇带和诱蝇纸上的家蝇平均数量进行计数后，每周两次记录家蝇羽化的数据。通过四种数据收集方法中的每一种，处理组和对照组的平均计数之间均存在显著差异。烯虫酯使粪桶中的家蝇羽化减少77.0%，诱蝇器中的减少65.5%，但使粘蝇带上的家蝇羽化增加19.2%，诱蝇纸上的增加92.2%。我们将处理组鸡舍中后两种计数方法家蝇数量的增加归因于家蝇从相邻未处理鸡舍的迁入。
