Three major components, ethyi-(E)-3-octenoate, geranyl acetate, and (E,E)-α-farnesene, emitted as volatiles by laboratory-reared and wild male medflies were collected and analyzed qualitatively and quantitatively. Peak emission of these compounds occurred during the third to fifth hours of the photophase and differences were observed in the ratios of the three components emitted by male laboratory-reared and wild flies. These three compounds were synthesized, and a method was developed to formulate a synthetic blend that released the compounds in a ratio similar to that emitted by wild male medflies. Attractiveness of the blend to female medflies was demonstrated under field conditions by comparing trap catches. Black spherical traps, baited with the synthetic blend to release 1.6 male equivalents, caught significantly more females than blank traps and traps from which the blend released was 0.3, 3.2 or 6.4 male equivalents.
三种主要成分，乙基-(E)-3-辛烯酸酯、乙酸香叶酯和(E,E)-α-法呢烯，由实验室饲养和野生雄性桔小实蝇作为挥发物收集和定性定量分析。这些化合物的峰值排放发生在光相的第三到第五小时，实验室饲养和野生雄蝇排放的三种成分的比例存在差异。这三种化合物被合成，并且开发了一种方法来配制一种合成混合物，该混合物以类似于野生雄性桔小实蝇释放的化合物的比例释放化合物。通过比较诱捕器的捕获量，在野外条件下证明了该混合物对雌性桔小实蝇的吸引力。黑色球形诱捕器，用合成混合物进行诱饵，释放 1.6 个雄性当量，比空白诱捕器和释放 0.3、3.2 或 6.4 个雄性当量的混合物的诱捕器捕获的雌性数量明显更多。
