Plutella xylostella
diamondback moth, cabbage moth
Plutella xylostella is a globally distributed moth species and one of the most economically significant agricultural pests worldwide. The small grayish-brown moth derives its common name from the cream-colored band that forms a diamond pattern along its back. Its larvae feed exclusively on cruciferous plants, causing extensive damage to cabbage, broccoli, cauliflower, canola, and other Brassica crops. The species has evolved resistance to nearly every class of insecticide, including Bacillus thuringiensis toxins, making it exceptionally difficult to control. Annual global management costs are estimated at $4–5 billion.
