Flea beetles, aphids, and three species of cabbage worms eat brussel sprouts and other cole crops. Cole crops include broccoli, cauliflower, Brussels sprouts, collards, kale, mustard greens, turnip greens, radishes, turnips, rutabagas and kohlrabi. The term cabbage worm is primarily used for Lepidoptera (butterfly and moths) whose caterpillar cause damage by eating holes in leaves. The 3 most common pest caterpillars of cole crops in MN are imported cabbage worm, cabbage looper and diamondback worm. Loopers are severe pest of Brussels sprouts are easy to control using the biological insecticide Bacillus thuringiensis (B.t.). This material gives excellent control of worms and can be used with complete safety around the home. It is sold under many trade names like Thuricide, Dipel and B.t. http://www.extension.umn.edu/garden/insects/find/caterpillar-pests-of-cole-crops-in-home-gardens/
