Trichopria drosophilae parasitizes Drosophila suzukii in seven common non-crop fruits

摘要: The invasive vinegar fly Drosophila suzukii not only infests and damages numerous fruit crops but also develops in many wild species semi-natural habitats. Biological control these refuges could reduce D. suzukii populations minimize their dispersal into crops. We investigated parasitization of D. by the pupal parasitoid Trichopria drosophilae seven common species. Development nutrient content differed among Nevertheless, T. significantly reduced numbers all fruits. development T. drosophilae was affected both quality host (size, content). In olfactometer assays, females preferred infested fruits to an empty most non-infested fruits, spent equal amount time on walking arena above Rhamnus cathartica Viscum album. Our results show that can utilize hosts from a variety therefore has potential be used as agent
