Scientific Name: Lipaphis erysimi
Common Name: Turnip aphid
Turnip aphids are one of several aphid species commonly found attacking canola and other Brassicaceous crops in southern Australia. Adults are up to 3 mm long, olive to greyish green in colour and have dark bands on the abdomen. Winged adults have dusky veins. Turnip aphids have a light covering of wax and are similar in appearance to cabbage aphids (Brevicoryne brassicae). Both of these species form dense colonies around the flowering tips of plants when present in high numbers. They suck sap and can reduce crop yields when numbers are high.
