Pest description and crop damage Cabbage and turnip aphids species are gray and adults are covered with a bluish-white waxy powder. They form colonies on foliage, on or in buds, or in flowers. High populations reduce seed set, cause seed pods to abort, cause premature plant death, and interfere with harvest operations.
