某些种类的果蝇雌性果蝇具有表皮碳氢化合物，作为接触信息素，能够诱导雄性求爱。在三种D. melanogaster species subgroup（D. melanogaster、黑腹果蝇D. sechellia和D.成年雄性和雌性具有不同长度和结构的碳氢化合物。在其他四种（D. simulans，拟谷盗D. mauritiana、毛叶杜父鱼D. yakuba和D. teissieri），两性之间没有质的差异。对求偶的观察表明，碳氢化合物在这里研究的所有物种中都起到了求偶诱导信息素的作用。雄性可以被诱导向其他苍蝇求爱，而不管性别或物种，如果求爱苍蝇的碳氢化合物对应于求爱雄性物种的主要雌性表皮碳氢化合物。男性物种，不显示碳氢化合物的二型性，主要是他们的物种的主要碳氢化合物。从二态物种的男性往往响应范围更广的碳氢化合物，也表现出高水平的求爱与年轻的苍蝇的性别和所有物种，其碳氢化合物有一些结构相似的同型成年女性。
Female fruitflies of certain species of Drosophila possess cuticular hydrocarbons which act as contact pheromones, capable of inducing male courtship. In three species of the D. melanogaster species subgroup (D. melanogaster, D. sechellia and D. erecta) adult males and females have hydrocarbons of different lengths and structures. In four other species (D. simulans, D. mauritiana, D. yakuba and D. teissieri) there is no qualitative difference between the sexes. Observations of courtships showed that hydrocarbons act as courtship-inducing pheromones in all the species studied here. Males can be induced to court other flies, regardless of sex or species, if the hydrocarbons of the courted fly correspond to the main female cuticular hydrocarbon of the species of the courting male. Males from species that do not show a hydrocarbon dimorphism responded mainly to the principal hydrocarbon of their species. Males from the dimorphic species tended to respond to a wider range of hydrocarbons, and also showed high levels of courtship with young flies of both sexes and all species, whose hydrocarbons had some structural similarities to those of homotypic adult females.
