The invasive fruit fly spotted-wing drosophila (Drosophila suzukii) causes 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. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest. (Photo credit: Flickr/Katja Schulz, CC BY 2.0)
