Includes Green apple aphid (Aphis pomi) and others
Pest description and damage Several species of aphids can become problems as foliar, stem, flower, bud bark or root feeding pests on broad-leaved trees. Aphids tend to be small (0.0625 to 0.125 inch in length), oval to pear-shaped, soft-bodied insects with piercing-sucking mouthparts. Color varies (black, green, pink, yellow, mottled, striped, etc.), but most aphids tend to match host plant coloration. Aphids often feed in colonies and are found on the most succulent plant tissues. Feeding damage to shrubs, trees and mature plants is usually minor, but can compromise the vigor of the host, and some leaf and shoot distortion can occur if aphid populations are high.
