Insecticidal fly baits are important tools for adult house fly, Musca domestica L. (Diptera: Muscidae), control, especially on animal operations. Two house fly baits, containing either cyantraniliprole or dinotefuran, were tested on a dairy farm for attractiveness over time compared to a sugar control. Sticky trap and bucket trap house fly catches were recorded for each bait type at 1 h, 3 h, 6 h, 12 h, 24 h, 48 h, 72 h, and 168 h. After 1 wk of exposure to flies and field conditions, these 'aged' baits were tested against fresh baits for fly visitation in the field over 1 h. House flies from each bait type (aged and fresh) were collected and kept under laboratory conditions to assess mortality over 3 d. Average visitation of individual flies to each bait type (fresh) in the field was also evaluated. Sticky traps did not show significant fly catch differences among bait types over time, however bucket trap catches did show significant differences for cyantraniliprole bait and dinotefuran bait compared to sugar at 72 h and 168 h. No significant differences among fly visitation to aged or fresh baits were found. Fresh cyantraniliprole bait and dinotefuran bait resulted in greater fly mortality compared to controls, but not compared to aged toxic baits. Average house fly visitation time was greatest for sugar and cyantraniliprole bait.
杀虫蝇饵是控制家蝇成虫（家蝇，双翅目：蝇科）的重要工具，尤其是在动物养殖场。在一个奶牛场对两种含有氰虫酰胺或呋虫胺的家蝇饵进行了测试，以比较它们与糖对照物随时间的吸引力。在1小时、3小时、6小时、12小时、24小时、48小时、72小时和168小时记录每种饵型的粘捕式诱捕器和桶式诱捕器捕获的家蝇数量。在暴露于苍蝇和田间条件1周后，将这些“老化”饵与新鲜饵在田间进行1小时的苍蝇访查测试。收集每种饵型（老化和新鲜）的家蝇并置于实验室条件下，以评估3天内的死亡率。还评估了田间单个苍蝇对每种饵型（新鲜）的平均访查情况。随着时间的推移，粘捕式诱捕器在不同饵型之间未显示出显著的捕蝇差异，然而在72小时和168小时时，桶式诱捕器捕获的氰虫酰胺饵和呋虫胺饵与糖相比确实显示出显著差异。在苍蝇对老化饵或新鲜饵的访查方面未发现显著差异。与对照相比，新鲜的氰虫酰胺饵和呋虫胺饵导致更高的苍蝇死亡率，但与老化的有毒饵相比则不然。家蝇对糖和氰虫酰胺饵的平均访查时间最长。
