The stable fly, Stomoxys calcitrans (L.), is a bloodsucking ectoparasite that causes irritation and distress to livestock, wildlife, and humans. Both sexes are vicious blood-feeders that feed on a variety of animals. Optically attractive sticky traps have been used to capture stable flies, and some companies claim that sticky traps can protect animals from the bites of stable flies. To further investigate the protective ability of sticky traps, Home and Garden Mosquito (HGM) traps were selected for evaluations at the University of Florida Horse Teaching Unit (HTU). Broodmares coated with fluorescent dust were either tethered to a post in the center of a paddock or released untethered into a paddock. HGM sticky traps were placed at the four compass points and four selected distances from the paddock center to capture stable flies before (unmarked) or after (marked) they visited the horses. More than 40% of flies captured on traps placed closest to the horses were marked. This indicates that the traps did not prevent the flies from visiting the horses. A percentage of marked and unmarked stable flies showed signs of blood in their guts indicating recent feeding. For unknown reasons, the number of stable flies marked with Signal Green dust exceeded the numbers marked with other colors. Although the HGM traps caught ample numbers of stable flies, the traps did not prevent stable flies from feeding on the horses. More work is needed to determine optimal trap placement and densities required to maximize stable fly management with traps.
厩螫蝇，又称厩蝇，是一种吸血的外寄生虫，会引起牲畜、野生动物和人类的不适和困扰。雌雄两性都是凶猛的吸血者，以各种动物为食。光学吸引力的粘性陷阱已被用于捕捉厩螫蝇，一些公司声称粘性陷阱可以保护动物免受厩螫蝇的叮咬。为了进一步研究粘性陷阱的保护能力，佛罗里达大学马教学单位（HTU）选择了 Home and Garden Mosquito（HGM）陷阱进行评估。用荧光粉覆盖的种马被拴在围场中心的一根柱子上，或者在没有拴绳的情况下被释放到围场中。HGM 粘性陷阱放置在四个罗盘点和四个离围场中心选定的距离处，在马被访问之前（未标记）或之后（标记）捕捉厩螫蝇。在离马最近的陷阱中捕获的苍蝇中，超过 40%是有标记的。这表明陷阱并没有阻止苍蝇靠近马。有标记和未标记的厩螫蝇的一定比例显示出其肠道中有血液的迹象，表明它们最近在进食。由于未知原因，用 Signal Green 粉尘标记的厩螫蝇数量超过了用其他颜色标记的数量。尽管 HGM 陷阱捕捉到了大量的厩螫蝇，但这些陷阱并不能阻止厩螫蝇叮咬马匹。需要做更多的工作来确定最佳的陷阱位置和所需的密度，以最大限度地利用陷阱来管理厩螫蝇。
