Effect of acetic acid bacteria colonization on oviposition and feeding site choice in and its related species.

Unlike many species of flies that colonize decaying fruits, lay eggs in ripening fruits. The oviposition and feeding site preferences for bacterial growth were quantified in multiple strains of and its closely related species, and . A continuous degree of preference for oviposition sites with growth both within and across species suggested that the separation in resource usage is notable but not complete among these species. The lack of interspecific differences in feeding site preference for -containing media implied that the oviposition site preferences evolved independently from the feeding site preference.
