Heliothis virescens

Resource Type
Common Name
tobacco budworm

Heliothis virescens, is a polyphagous Lepidopteran species found throughout North, Central, and South America. It is commonly known as the tobacco budworm and develops on tobacco, as well as cotton, soybeans, and garbanzo beans in its larval stages. Historical pressure by Heliothis virescens, a difficult to manage pest due to its ability to adapt to insecticides, has shaped current cotton cultivation practices in the southern United States. Today, much of the cotton grown in the United States is genetically modified to express Bt toxins, in part due to the efficacy of these toxins against Heliothis virescens. The genome assembly of Heliothis virescens was produced as part of a USDA-funded project to determine how Lepidopteran pests adapt to the widespread distribution of Bt-expressing corn and cotton in the landscape.
