A granular formulation of novaluron (Novaluron 0.2G, 0.2% [AI]), a newer benzoylphenyl urea insecticide, was evaluated for its efficacy in controlling the larval stage of horn flies, Haematobia irritans (L.); house flies, Musca domestica L.; and stable flies, Stomoxys calcitrans (L.), in cow manure. Various rates and insecticide placement locations (top, middle, and bottom of manure) were evaluated in this study and all combinations of these variables reduced adult emergence of all three species when compared with the untreated controls. The presence of deformed pupae indicated that novaluron had an insect growth regulator effect on the developing fly larvae. Top, middle, or bottom application rates of 0.125, 0.195, 0.25, and 0.375 g novaluron onto manure samples, reduced adult horn fly emergence by > 90%. Middle and bottom application rates of 0.195, 0.25, and 0.375 g novaluron reduced adult house fly emergence >93%. All rates and placement combinations resulted in >98% reduction of adult stable fly emergence. The level of control efficacy observed against these three fly species along with the ease of use of a granular formulation, make this product an ideal candidate for use in an integrated livestock pest management program.
新型苯甲酰基脲类杀虫剂双氧威（Novaluron 0.2G，0.2%[AI]）颗粒剂，用于控制牛粪便中厩螫蝇幼虫、家蝇和厩蝇的效果进行了评估。本研究评估了不同剂量和杀虫剂放置位置（粪便的顶部、中部和底部），与未处理的对照组相比，所有这些变量的组合均降低了三种成虫的羽化率。存在畸形蛹表明双氧威对正在发育的蝇幼虫有昆虫生长调节剂的作用。在粪便样本上以 0.125、0.195、0.25 和 0.375 g 的顶部、中部或底部剂量施用双氧威，可使厩螫蝇的成虫羽化率降低超过 90%。在中部和底部以 0.195、0.25 和 0.375 g 的剂量施用双氧威，可使家蝇的成虫羽化率降低超过 93%。所有剂量和放置组合均使厩蝇成虫羽化率降低超过 98%。该产品对这三种蝇类的防治效果水平，以及颗粒剂使用的便利性，使其成为综合牲畜害虫管理计划的理想选择。
