The feeding behavior of the potato leafhopper, Empoasca fabae, is directly responsible for damage to several crops, including alfalfa, soybeans, and potatoes. Although much research has been performed on E. fabae, certain questions about its precise feeding style are still unanswered. This article reviews what is known about leafhopper feeding in general and compares that with the feeding behavior of the potato leafhopper. Descriptions emphasize the sequences involved in feeding subsequent to the insect's arrival on a host plant. Recent evidence supporting a reinterpretation of potato leafhopper feeding is presented. Visual, biochemical, and electrobehavioral evidence supports the result that E. fabae is primarily a mesophyll feeder, using a lacerate-and-flush strategy while feeding on alfalfa or broad beans. Although some phloem feeding may occur, this feeding site has not been demonstrated conclusively.
