Pear, flowering (Pyrus)-Aphid

Includes green peach aphid (Myzus persicae)

Pest description and damage Aphids tend to be small (0.0625 to 0.125 inch long), oval to pear-shaped, soft-bodied insects with piercing-sucking mouthparts. Color varies but most aphids tend to match host plant coloration. Aphids tend to feed in colonies and are often found on the most succulent plant tissues. Feeding damage to trees is usually minor, but if heavy can compromise the vigor of the host. Aphids produce honeydew that supports the growth of a black sooty mold fungus. Some aphids are vectors of plant diseases, particularly viruses.
