## The Biology and Control of Flea Beetles Flea beetles are small, jumping insects that can cause significant damage to plants. They feed on the leaves of plants, creating small holes that can reduce the plant’s ability to photosynthesize. In severe cases, flea beetle infestations can kill plants. ### Life Cycle Flea beetles overwinter as adults. In the spring, they emerge from hibernation and begin to feed on plants. Adult beetles lay eggs in the soil, and the eggs hatch into larvae. The larvae feed on the roots of plants. When they are mature, the larvae pupate and emerge as adult flea beetles. ### Host Plants Flea beetles can infest a wide variety of plants, including: * Crucifers (broccoli, cabbage, cauliflower, kale, turnips) * Solanaceae (tomatoes, peppers, eggplants) * Cucurbits (cucumbers, squash, melons) * Legumes (beans, peas, lentils) * Asteraceae (sunflowers, daisies, lettuce) ### Damage Symptoms Flea beetle damage is characterized by small, round holes in the leaves of plants. The holes are typically 1-2 mm in diameter. Heavy feeding can cause the leaves to become skeletonized. Flea beetle damage can also reduce the yield and quality of crops. ### Identification Flea beetles are small, oval-shaped insects that are typically black, brown, or metallic blue or green. They are about 2-3 mm long. Flea beetles have long, jumping legs that they use to escape predators. ### Control Methods There are a number of methods that can be used to control flea beetles, including: * **Cultural Controls:** Cultural controls include crop rotation, planting resistant varieties, and removing plant debris from the garden. * **Biological Controls:** Biological controls include introducing natural enemies of flea beetles, such as parasitic wasps and predatory beetles. * **Chemical Controls:** Chemical controls include insecticides. Insecticides should be used as a last resort, as they can kill beneficial insects.
