 Wingless potato aphid adult Potato
Aphid Potato aphids are large, green, football-shaped aphids 2.5 to 3.5 mm long. They are an efficient transmitter of potato virus Y, but not of potato leafroll virus. This species occurs on potatoes, but nightshade is the preferred host. Damage is caused by the aphid's sucking plant sap; large populations predispose the plant to wilt and sunburn and will reduce yields. Host plants: apples, beans, clover, corn, nightshade, peas, pigweed, lambsquarters, potatoes, shepherdspurse.
