Cabbage maggots are insects that damage cole crops by feeding on the plant's roots and lower stems. Wounds produced by this feeding can create entry points for several cole crop diseases. Cabbage maggots are a pest of all cole crops, including cabbage, broccoli, cauliflower, and Brussels sprouts. They can also be a very serious problem on rutabagas. Early season transplants, late-season seedlings, and spring root crops are damaged most severely. This fact sheet details the pest's life cycle and offers effective means of control (2 pages; 2001).
