在风洞嗅觉仪中，成熟黑腹果蝇雄性的戊烷提取物大大增加了食物气味对雄性和雌性的吸引力。雌性动物的浸提液未引起此类增加。从该提取物中分离得到一种活性成分，经鉴定为（Z）-11-十八碳烯基乙酸酯（cis-vaccenyl acetate，cVA）。酯键的水解或双键向9位的移动破坏了活性。成熟的处女男性释放cVA到他们的饲养瓶，和合成CVA的量等于释放每个男性引起显着的生物测定反应。女性，这是已知的，以获得cVA从男性在交配过程中，被发现排放相对大量的酯到他们的喂养瓶内交配后6小时内。cVA是D.黑腹，劝阻男性从追求其他男性或最近交配的女性;它现在似乎有一个更长的范围功能以及。
Pentane extracts of mature Drosophila melanogaster males substantially increased the attractiveness of food odors to both males and females in a wind-tunnel olfactometer. Extracts of females caused no such increase. An active component of the extract was isolated and identified as (Z)-11-octadecenyl acetate (cis-vaccenyl acetate, cVA), and synthetic cVA was active in bioassay. Hydrolysis of the ester linkage or movement of the double bond to the 9 position destroyed the activity. Mature virgin males released cVA into their feeding vials, and amounts of synthetic CVA equal to that released per male caused significant bioassay responses. Females, which were known to receive cVA from males during copulation, were found to emit relatively large amounts of the ester into their feeding vials within 6 hr after mating. cVA had been demonstrated previously to be a close-range pheromone in D. melanogaster, discouraging males from courting other males or recently mated females; it now appears to have a longer-range function as well.
