Leafhoppers attack many crops including beet, blackeye peas, celery, cowpea, cucumber, eggplant, garden bean, green bean, lettuce, lima beans, melon, peanut, potato, summer squash, tomato, and watermelon. Nymphs and adults suck sap from the phloem of plants usually from the under surfaces of the leaves. This leafhopper produces a toxicogenic disease called hopperburn when the digestive juices of the insect react with plant tissue. Hopperburn is characterized by yellowing, chlorotic stippling and leaf malformation and tip burn.One to two eggs are inserted from the undersides of leaves. Eggs hatch in about 10 days.Immature leafhoppers, or nymphs are quite active and run in a sideward direction. Nymphal development is completed in 14 days. Females begin laying eggs 6 - 7 days after the final nymphal molt. They can live for several months, and can lay 200 - 300 eggs during their lifetime.Adult leafhoppers fly or jump when disturbed, in response to overcrowding, decline of host plants, and after reaching adulthood.
