n Farmer’s Weekly - Beware those aphids! : vegetable production




The recent announcement that aphids and not leaf hoppers are the vector for the spread of the brassica stunting disorder virus (BSD) makes sense. You rarely see leaf hoppers in cabbage lands, whereas aphids are a major pest of brassicas, especially during the cooler months. Two species of aphid are likely to attack crops - the cabbage aphid (Brevicoryne brassicae) and the false cabbage aphid (Lipaphis pseudobrassicae). The former prefers the cooler months. It creates white patches where it feeds and causes the leaves to curl over the colony, thus protecting it. The aphids have a distinct light-grey wax body covering.
