Heliothinae

Heliothinae is a small, cosmopolitan subfamily of moths in the family Noctuidae, with about 400 described species worldwide. It includes a number of economically significant agricultural pest species, such as Helicoverpa armigera and Helicoverpa zea.

Taxonomy
The subfamily has been studied extensively. Important works include studies by Hardwick (1965 and 1970) and Matthews (1988).

Distribution and diversity
Heliothinae is a cosmopolitan subfamily of around 400 species. Its species thrive in hot, dry regions of the world, and the subfamily has its highest species diversity in seasonally-arid tropics and subtropics, such as those found Australia, sections of Asia, the southwest region of the United States, and Africa.

Larvae
The subfamily includes both specialist species, of which the larvae feed on only a limited range of plants, and polyphagous generalist species.

The subfamily contains several agricultural pests, including Helicoverpa armigera, Helicoverpa assulta, Helicoverpa zea, Helicoverpa punctigera and Heliothis virescens.
