EmailChewing pests
Adult spotted cucumber beetles chew holes in plant leaves and flowers. They commonly feed on pollen. Although adults typically cause minimal damage, large populations may significantly damage plants, particularly those in the sunflower family, including chrysanthemum, coreopsis and dahlia. The adults overwinter in plant debris.
Adults are 6 mm long and yellow-green with a small black head. There are typically 12 black spots on the hard wing covers.
Management
In early spring, cover plants with a row cover until blooming starts. Remove and discard any plant debris. Contact insecticides may be used to control the adults.
