| Abstract: | "(S)-2-Pentadecyl acetate and 2-pentadecanone were identified as the major aggregation pheromone components, inDrosophila busckii. Both sexes of flies were attracted equally in a wind-tunnel olfactometer. The flies also responded to racemic 2-pentadecyl acetate but not to the pureR enantiomer. In bioassay, (S)-2-pentadecyl acetate and 2-pentadecanone were each active alone, and a mixture of both increased the number of flies responding ca. twofold. The aggregation pheromone components are found in the ejaculatory bulb of sexually mature males and are transferred primarily to the female cuticle during mating. One third of the pheromone transferred is released by the female to the surrounding environment in a few hours after mating. None of the aggregation pheromone components remained on the mated female's cuticle, leaving two thirds unaccounted for. The same results were obtained when racemic 2-pentadecyl acetate was topically applied to immature and mature virgin males and females. BothD. mulleri andD. busckii were attracted to (S)-2-acetates of 13, 14 and 15 carbons, butD. mulleri preferred (S)-2-tridecyl acetate andD. busckii preferred (S)-2-pentadecyl acetate" |
