Mate choice in Drosophila melanogaster and D. sechellia: criteria and their variation depending on courtship song

Courtship song is one of the most important male signals in Drosophila mating. A femaleD.melanogaster copulates more readily when given a conspecific type of courtship song. FemaleD.melanogaster accepted winged D.sechellia more than wingless ones in a no choice test. Copulation frequencies varied be...

Description
Summary:Courtship song is one of the most important male signals in Drosophila mating. A femaleD.melanogaster copulates more readily when given a conspecific type of courtship song. FemaleD.melanogaster accepted winged D.sechellia more than wingless ones in a no choice test. Copulation frequencies varied between strains and were significantly correlated with male mating propensity ofD.sechellia . Females from three of five strains of D.sechellia accepted wingedD.melanogaster less than wingless ones in no choice tests, suggesting that D.melanogaster songs reduce mating in D.sechellia females. Multiple choice tests showed that males prefer conspecifics. In female choice tests, D.melanogaster females copulated with winged heterospecific D.sechellia males more than with wingless conspecific D.melanogaster males in the confined condition, suggesting that song differences between D.melanogaster and D.sechellia affect D.melanogaster females less than the absence of courtship song.
