Der Konsum von Alkohol wirkt sich direkt und positiv auf den Paarungserfolg männlicher Taufliegen aust. Dieser Effekt kommt durch die verstärkte Produktion von Sexualpheromonen nach Alkoholkonsum zustande: Männchen, die Alkohol konsumiert haben, sind attraktiver für Weibchen. Männliche Fliegen haben werden daher stark von Alkohol angezogen, besonders dann, wenn sie noch unverpaart sind. Drei verschiedene neuronale Schaltkreise im Hirn der Fliegen steuern die Reaktion, wenn die Fliegen Alkohol riechen.

Alcohol consumption has a direct and positive effect on the mating success of male fruit flies. This effect is due to the increased production of sex pheromones after alcohol consumption: males who have consumed alcohol are more attractive to females. Male flies are therefore strongly attracted to alcohol, especially if they have not yet mated. Three different neural circuits in the flies‘ brains control the response when the flies smell alcohol.
