Frequently Asked Questions
Not precisely. 'Cabbage worm' often refers to the larvae of the cabbage white butterfly (Pieris rapae), which is velvety green. The cabbage looper is a different species (Trichoplusia ni), is a lighter, more lime-green, and has white stripes. Both are pests of brassicas.
Yes. Methods include hand-picking, using row covers as a barrier, encouraging natural predators (birds, parasitic wasps), and applying organic controls like Bacillus thuringiensis (Bt) or spinosad.
The adult is a nocturnal moth with a wingspan of about 1.5 inches. Its forewings are mottled brown and grey with a distinctive silvery-white figure-8 or 'U' shaped mark near the center.
No. While cabbages are a preferred host, they also feed on a wide range of plants including broccoli, cauliflower, kale, lettuce, spinach, tomatoes, and cucumbers.
