Aggression and mating success in Drosophila melanogaster


THE value of Drosophila melanogaster as an experimental animal for the study of the genetics of behaviour increases as more specific behaviours are shown to exist in this species. Although aggressive behaviour has been reported for D. subobscura1 and some Hawaiian2 species, and has been briefly mentioned for many other species3, it has not yet been described for D. melanogaster. We have repeatedly observed behaviours which we interpreted as aggressive and here, report an experiment designed to investigate aggression and its relationship to mating success—an important component of fitness.
