They feed on the underside of leaflets. Also, vegetable varieties with hairier leaves appear to be less attractive to PLHs and thus less prone to PLH damage. They are even more damaging in tropical areas. They are even more damaging in tropical areas. "TARS-LH1 could contribute to reducing these major inputs in common bean farming," says Porch. The first signs of feeding are pale leaf veins and curling leaves (see image, left). The migratory nature of this native pest makes its arrival time and population size unpredictable. To combat the leafhopper threat, researchers are continuously trying to develop resistant varieties of crops. Potato leafhopper (PLH), Empoasca fabae, is a potentially serious annual pest of a wide range of plants including, but not limited to, alfalfa, apple, beans (all types), clover, dahlia, eggplant, potato, rhubarb, soybean, strawberry and many types of bedding plants. Green beans are particularly susceptible, with some plants sustaining severe damage from only a few leafhoppers, especially when insects feed on early growth.
