Green peach aphid

Myzus persicae

Adult green peach aphids appear in the summer, and are 1.8 to 2.1 mm long; the head and thorax are black, and the abdomen yellow-green with a dark patch on the back. The nymphs are at first greenish, then yellowish in colour; those that become winged females may be pinkish. Wingless adults resemble nymphs and are 1.7 to 2.0 mm long.

In the warmer months, and throughout the year in warmer climates, the green peach aphid reproduces asexually; adults produce nymphs on a wide variety of herbaceous plant material, including many vegetable crops such as cabbage and its Brassica relatives, potato and other crops of the family solanaceae, celery, mustard, pepper, pumpkin, okra, corn, and sunflower and other flower crops. Herbaceous weeds, such as white goosefoot (Chenopodium album) and common tumble weed.
