Injury from feeding by green peach aphid is often subtle and seldom reflected by obvious changes in plant growth or growth form. Frequently, growers become aware of a damaging aphid infestation because of premature death or early senescence of their crop. By this time, damage in the form of reduced yield is irreversible.

Damage resulting from the transmission of plant-infecting viruses is usually much more dramatic than direct feeding injury. Snap beans are subject to numerous aphid transmitted viruses such as common mosaic virus. Green peach aphids also transmit many viruses to potatoes.
