(Z)-10-Heptadecen-2-one was identified as the major aggregation pheromone component inDrosophila martensis, D. buzzatii, andD. serido. Aliphatic 2-ketones were not detected in newly eclosed males or in virgin females of any age. The amount of (Z)-10-heptadecen-2-one in the ejaculatory bulb and on the cuticle of males increased with age. Only trace quantities of (Z)-10-heptadecen-2-one were transferred to the female during mating. 2-Tridecanone was found in the ejaculatory bulb and on the cuticle of maleD. martensis andD. buzzatii, but notD. serido. The amount of 2-tridecanone increased with age. Unexpectedly,2-tridecanone inhibited the aggregation activity of (Z)-10-heptadecen-2-one inD. buzzatii. InD. martensis, 2-tridecanone was significantly less attractive than controls but did not decrease the attractiveness of one fly equivalent of (Z)-10-heptadecen-2-one.D. serido males did not have any 2-tridecanone and the activity of (Z)-10-heptadecen-2-one was not diminished inD. serido by the presence of 2-tridecanone.
（Z）-10-十七碳-2-酮被鉴定为果蝇 martensis、D. buzzatii 和 D. serido 的主要聚集信息素成分。新羽化的雄性或任何年龄的处女雌性体内均未检测到脂族 2-酮。（Z）-10-十七碳-2-酮在精囊中和雄虫表皮上的含量随年龄的增加而增加。在交配过程中，只有痕量的（Z）-10-十七碳-2-酮转移到雌性身上。2-十三酮存在于雄性果蝇 martensis 和 D. buzzatii 的精囊中以及表皮上，但不存在于 D. serido 中。2-十三酮的含量随年龄的增加而增加。出人意料的是，2-十三酮抑制了 D. buzzatii 中（Z）-10-十七碳-2-酮的聚集活性。在 D. martensis 中，2-十三酮的吸引力明显低于对照，但不会降低一只果蝇等效量（Z）-10-十七碳-2-酮的吸引力。D. serido 雄性体内没有任何 2-十三酮，而且 2-十三酮的存在并没有降低 D. serido 中（Z）-10-十七碳-2-酮的活性。
