Mechanisms of premating and postmating isolation between Drosophila melanogaster and its sibling species, D. simulans , D. mauritiana , and D. sechellia , are reviewed here. As D. melanogaster has been used as a “model organism” in a variety of studies, we can apply much knowledge about this species to interspecific hybridizations. Mating success between species is low because of species specificity of pheromonal and acoustic signals and the receivers, although other factors are also involved. On the other hand, genetic incompatibility between species results in inviability and sterility in F 1 and backcross hybrids. Studies of reproductive isolation between these Drosophila species will shed light on animal speciation and the origin of biodiversity.
