A female spotted wing drosophila (Drosophila suzukii) on a cherry. Spotted-wing drosophila cause extensive damage to cherry and berry crops, and effective monitoring is vital to control efforts. A new study in Michigan found that spotted-wing drosophila consistently prefer red, glue-covered monitoring traps made of rectangles of plastic or spheres of plastic compared to the most commonly used clear deli-cup traps.
