Myzus persicae (Sulzer) Wingless forms are teardrop shaped. They are usually light green, but in late summer they may be pink. Winged forms have a brown, or black head and thorax with a green abdomen and a darker spot on their backs. Immatures are smaller and those which will be winged will have wing pads. They exist world wide.

Plant Symptoms: Severe infestations may cause stunting, curling and other distortions of the leaves. The leaves also can become covered with cast skins, honeydew, and sooty mold.

The green peach aphid can act as a vector for over 50 virus diseases, such as Cucumber Mosaic Virus and Tobacco Etch Virus. Severe aphid infestations can reduce yield and fruit quality.
