Trap Spacing and Placement: When trapping for more than one species of moth, separate traps for different moth species by at least 20 meters (65 feet).

Identification
ID/Diagnostic: Morphological
Morphological: Helicoverpa armigera can be visually screened to some degree but definitive identification requires dissection. Helicoverpa armigera and the native, abundant species, Helicoverpa zea are very similar looking. Helicoverpa zea are attracted to the H. armigera lure and are commonly found in H. armigera traps.
Final identification is by dissection of (adult) male genitalic structures.
Mistaken Identities:
Present in U.S.: Helicoverpa zea and Heliothis virescens.
Not present in U.S.: Helicoverpa punctigera and Helicoverpa assulta.
