Brevicoryne brassicae, commonly known as the cabbage aphid or cabbage aphis, is a destructive aphid (plant louse) native to Europe that is now found in many other areas of the world. The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus Brassica, but do not feed on plants outside of the Brassicaceae family. The insects entirely avoid plants other than those of the Brassicaceae family, even though thousands may be eating broccoli near strawberries, the strawberries will be left untouched.
