Evidence for an aphrodisiac pheromone of femaleDrosophila

Summary We report here direct evidence for the involvement of a pheromone in the induction of male wing vibration, an important fixed action of theDrosophila melanogaster courtship pattern. This chemical stimulus is produced by mature females but not by mature males. The behavioral response is proportional to the pheromone concentration.Acknowledgments. Thanks are due to Drs Y.
