Field studies evaluated 1-octen-3-ol (octenol), carbon dioxide (dry ice), and a combination of both attractants in comparison with unbaited traps for collecting greenhead flies on a Massachusetts salt marsh. The carbon dioxide (CO2)-baited trap collections, and the CO2 with octenol-baited trap collections were more than 300% greater than the unbaited collections. The octenol-baited traps collected 83% more greenhead flies than unbaited traps. Afternoon trap collections were 2.5 times greater than morning collections. Dissections and measurements of a sample of the flies collected indicated that the "cryptic species" composition of greenhead flies was 77% Tabanus nigrovittatus and 23% Tabanus conterminus. Ovarian tracheole examinations of a sample of the flies showed that 99% of the greenhead flies had laid eggs before being trapped. The use of CO2 as an attractant in the traps could be cost effective in small problem areas, and the use of octenol in the box traps should be evaluated in large areas.
实地研究评估了1-辛烯-3-醇（辛烯醇）、二氧化碳（干冰）以及这两种引诱剂的组合，用于在马萨诸塞州的一个盐沼上与未设诱饵的诱捕器相比收集绿头蝇。用二氧化碳（CO₂）作诱饵的诱捕器收集量，以及用二氧化碳加辛烯醇作诱饵的诱捕器收集量比未设诱饵的收集量高出300%以上。用辛烯醇作诱饵的诱捕器收集的绿头蝇比未设诱饵的诱捕器多83%。下午的诱捕器收集量是上午收集量的2.5倍。对收集到的部分绿头蝇样本进行解剖和测量表明，绿头蝇的“隐性物种”组成是77%的黑纹虻和23%的同缘虻。对部分绿头蝇样本进行的卵巢气管检查显示，99%的绿头蝇在被捕获之前已经产卵。在小面积问题区域使用二氧化碳作为诱捕器中的引诱剂可能具有成本效益，而在大面积区域应评估在箱式诱捕器中使用辛烯醇的效果。
