Helicoverpa armigera (Hübner, 1809) (Pogue 2004)
Old World bollworm (OWB), cotton bollworm, African bollworm
Found throughout all of the Old World between 40°N and 40°S (Nibouche et al. 1998)
In September 2014, the first U.S. detection of OWB occurred in western Puerto Rico (Tembrock et al. 2019)
Frequently intercepted at U.S. ports of entry on imported cut flowers and herbs (Pogue 2004)
Feeds on a large range of plant hosts and could cause serious economic losses to corn and cotton in the U.S. (Tay et al. 2013)
