spotted-wing drosophila feeding on strawberry puree

spotted-wing drosophila feeding on strawberry puree

In the field, adult spotted-wing drosophila flies (Drosophila suzukii) lap up juices from the fresh egg-laying wounds they create on fruit, but in lab experiments they feed on strawberry puree. A recent study at North Carolina State University shows that DNA analysis of spotted-wing drosophila can detect whether they fed on strawberries as much as seven days prior. Researchers hope the proof of concept will lead to more accurate analysis of spotted-wing drosophila dispersal in the field. (Photo credit: Lauren Diepenbrock, Ph.D.)
