Social signals mediate oviposition site selection in Drosophila suzukii

Abstract The information that female insects perceive and use during oviposition site selection is complex and varies by species and ecological niche. Even in relatively unexploited niches, females interact directly and indirectly with conspecifics at oviposition sites. These interactions can take t...
