Hay mixed with manure and urine residues at sites where hay has been provided as supplemental winter feed for cattle provide an excellent substrate for the development of immature stable flies, Stomoxys calcitrans (L.). Such sites are primary sources of early summer stable flies in the central United States and no effective measures are currently available to control fly development in them. A single application of granular cyromazine in May provided 97% reduction in the number of adult stable flies emerging from hay feeding sites. Stable fly control did not decline during the 12 wk season. A small decline in control was observed relative to anthomyiid, sarcophagid, and syrphid flies developing in the hay feeding sites. However, none of those flies are considered to be pests and > or = 50% control of those flies was maintained for 65 d after application. Cyromazine offers a safe and affordable option for the control of immature stable flies developing in winter hay feeding sites. Controlling those flies should reduce the estimated $2 billion per year of lost production in U.S. cattle industries attributable to stable flies.
在为牛提供干草作为冬季补充饲料的地方，干草与粪便和尿液残渣混合在一起，为不成熟的厩螫蝇（Stomoxys calcitrans（L.））的发育提供了极好的基质。这些地点是美国中部初夏厩螫蝇的主要来源，目前没有有效的措施来控制它们的蝇类发育。5 月施用一次颗粒化环丙氨嗪可使从干草喂养地点出现的成年厩螫蝇数量减少 97%。在 12 周的季节中，厩螫蝇的控制没有下降。与在干草喂养点发育的嗜人按蚊、麻蝇和实蝇相比，控制效果略有下降。然而，这些蝇类都不被认为是害虫，在施用后 65 天内仍能保持 >或= 50%的控制效果。环丙氨嗪为控制冬季干草喂养点发育的不成熟厩螫蝇提供了一种安全且经济实惠的选择。控制这些蝇类应该可以减少美国养牛业每年因厩螫蝇而损失的 20 亿美元估计产值。
