In an initial observation, large numbers of muscoid flies (Diptera) were captured as nontarget insects in traps baited with solutions of acetic acid plus ethanol. In subsequent field experiments, numbers of false stable fly Muscina stabulans (Fallén) and little house fly Fannia canicularis (L.) trapped with the combination of acetic acid plus ethanol were significantly higher than those trapped with either chemical alone, or in unbaited traps. Flies were trapped with acetic acid and ethanol that had been formulated in the water of the drowning solution of the trap, or dispensed from polypropylene vials with holes in the vial lids for diffusion of evaporated chemical. Numbers of both species of fly captured were greater with acetic acid and ethanol in glass McPhail traps, compared to four other similar wet trap designs. This combination of chemicals may be useful as an inexpensive and not unpleasant lure for monitoring or removing these two pest fly species.
在初步观察中，大量蝇类（双翅目）作为非目标昆虫在以醋酸加乙醇溶液为诱饵的诱捕器中被捕获。在随后的田间试验中，用醋酸加乙醇组合诱捕到的厩腐蝇Muscina stabulans（法伦）和小家蝇Fannia canicularis（林奈）的数量显著高于单独使用任何一种化学物质诱捕到的数量，也高于未设诱饵的诱捕器诱捕到的数量。苍蝇是被置于诱捕器溺液水中配制的醋酸和乙醇诱捕的，或者是从聚丙烯小瓶中释放出来的，小瓶盖子上有孔以便蒸发的化学物质扩散。与其他四种类似的湿式诱捕器设计相比，在玻璃麦克费尔诱捕器中，用醋酸和乙醇捕获的这两种蝇类数量更多。这种化学物质组合可能作为一种廉价且气味不刺鼻的诱饵，用于监测或清除这两种害虫蝇类。
