Plastic Mulches Reduce Spotted-Wing Drosophila in Fall-Bearing Raspberries

Hannah McIntosh, PhD Student, Dept of Entomology

We tested black, white, and metallic plastic mulches as a cultural practice for managing spotted-wing drosophila. All three mulches reduced the number of flies in the canopy by 40-50% and reduced larval infestation of fruit by 50-70%.
