Leaf Hoppers consist of any of the small, slender, often beautifully colored and marked sap-sucking insects of the large family Cicadellidae (Jassidae) of the order Homoptera. They are found on almost all types of plants; however, individual species are host specific. Although a single leafhopper does no damage to a plant, collectively they can be serious economic pests. Their feeding may injure the plant in any of several ways: by removing sap, destroying chlorophyll, transmitting diseases, or curling leaves. The host plant is also punctured during egg laying. Most leafhoppers are several millimeters long; some may grow to 15 mm. They excrete honeydew, a sweet by-product of digestion, and are responsible for hopperburn, a diseased condition caused by the insects’ injection of a toxin into the plant as they feed. Control is best achieved with the proper treatment of a contact insecticides applied at the correct time.
