Brevicoryne brassicae, commonly known as the cabbage aphid, cabbage aphis or turnip aphid, is a destructive aphid (plant louse) native to Europe that is now found in many other areas of the world.[1] The aphids feed on many varieties of produce, including cabbage, broccoli, Brussels sprouts, cauliflower and many other members of the genus Brassica,[1] but do not feed on plants outside of the Cruciferae family.[2]

Cabbage aphids, from the genus Brevicoryne of the family Aphididae, are grayish-green, but a waxy covering gives them a grayish-white[2] to powdery blue[3] appearance.


Predator defense mechanism

Cabbage aphids have a unique defense mechanism against predators. The aphids produce a myrosinase (beta-thioglucoside glucohydrolase) enzyme in head and thoracic muscles; the aphids also uptake glucosinolates, particularly sinigrin, from the plants on which they feed, storing the glucosinolates in their haemolymph. (Glucosinolates are natural defenses for plants in the order Brassicales against pests and herbivores.) The combination of the glucosinolates and the myrosinase enzyme produces a violent chemical reaction that releases the mustard oil chemical allyl isothiocyanate.[4] The defense mechanism has a dramatic negative effect on the survival of the larval ladybird predator Adalia bipunctata.[5] The chemical defence of the aphids has been likened to a "walking mustard oil bomb".[4][5]

The myrosinase from Brevicoryne brassicae appears to have evolved separately from myrosinases found in plants, possibly a case of convergent evolution.[6][7] Aphid myrosinase appears to have greater similarity to animal beta-O-glucosidases than to plant myrosinases.[7]

Pest control

Different varieties of cultivars have varying resistance to Brevicoryne brassicae.[8]

Diaeretiella rapae is a common wasp parasite of cabbage aphids.[2] Other controlling insects include ladybird beetles, syrphid fly larvae, and lacewing larvae.[1][2] Some insecticidal soaps may be effective in treating aphid infestations.[2]
