The potato leafhopper, Empoasca fabae, is a serious pest in the E United States. It causes a disease commonly known as hopperburn on potatoes and damages many other plants, including apples, beans, and clover. As a result of the potato leafhopper's attack, the leaf's conducting tissue is plugged; the plant leaves curl and begin to turn brown near the tip, and eventually the whole leaf appears blighted. As many as 5 to 6 million leafhoppers may be found per acre. Other leafhopper pests include the beet leafhopper, which causes the beet disease known as curly top in the W United States; the grape leafhopper; the rose leafhopper; and the apple leafhopper.
Many leafhoppers have a single generation per year, but there may be several. They overwinter either in the adult or egg stage, depending on the species. Eggs are laid singly or a few at a time in stems and leaves. The adults overwinter only in the south; those migrating north each year cause much damage, but are usually killed by the frost.
Leafhoppers are classified in the phylum Arthropoda, class Insecta, order Homoptera, family Cicadellidae.
