Helicoverpa armigera
（重定向自Tobacco Budworm）
The cotton bollworm, corn earworm or Old World (African) bollworm, Helicoverpa armigera, (also known as the scarce bordered straw in the UK, where it is an immigrant) is a moth, the larvae of which feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named, related species Helicoverpa zea.
