Hemp-Cucumber beetle

Western spotted cucumber beetle (Diabrotica undecimpunctata)

Pest description and crop damage The Western spotted cucumber beetle (Order: Coleoptera; Family: Chrysomelidae) is yellowish green and 0.25-inch-long, and has 11 black spots on its wing covers. Adult cucumber beetles eat small holes in the leaves and flowers of many crops. They are commonly found feeding on hemp. Damage to mature hemp plants is usually minor and does not require control. No scouting or thresholds are needed since this is a minor pest on hemp. See Common Pests of Vegetable Crops for more information.
