Green peach aphids form colonies on the leaves. They transmit the beet jaundice virus, which causes the symptom of yellowing leaves.
They also carry other viral diseases (e.g., potato leaf blight and leaf curl).
The adults are 2 mm long and yellowish green in color. The abdomen bears long tubular appendages (siphons). Winged and wingless forms coexist. In winged aphids the head and thorax are darker in color than in wingless aphids.
The nymphs resemble the adults in appearance, but are often reddish in color.
