Not known to transmit any human or animal pathogens.
Not known to vector any pathogens or other associated organisms but damage may lead to invasion by secondary pests.
Approved Method(s)
| Method | Detail | NAPIS Survey Method |
|---|---|---|
| Trap | 4 - Heliothis Trap | 3001 - General Trapping Procedure |
| Trap | 50 - Tri-colored bucket trap | 3001 - General Trapping Procedure |
| Trap | 51 - All-green bucket trap | 3001 - General Trapping Procedure |
Traps should be placed 1.5 to 1.8 m (~5 to 6 ft) above the ground.
When trapping for more than one species of moth (that require different lures), separate traps for different moth species by at least 20 meters (65 feet).
Approved Lure(s)
| NAPIS Code | Product | Dispenser | Effectiveness | Compound(s) | 21 | Helicoverpa armigera Lure | rubber septum | 28 days | Z11-16Ald Z9-16Ald butylated hydroxytoluene |
|---|
IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.
Survey Recommendations
A Likelihood of Establishment Map is now available. This survey should only be considered in the states with appropriate conditions and suitable hosts for this insect. The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from PPQ PPRA.
Adult
Adult moths emerge between April and June depending on latitude, and they may be observed until October. In a study of overwintering pupae, 153 to 347 degree-days were required for emergence of 10 to 90% of adults, respectively (Mironidis et al., 2010). The lower threshold temperature (LTT) for larval and pupal stage development of nondiapausing individuals is about 10.5 °C (51 °F) and 10.2 °C (50 °F), respectively (Mironidis et al., 2010). About 475 degree-days are needed to complete development from egg to adult (Mironidis and Savopoulou-Soultani, 2012; Mironidis, 2014).
Helicoverpa armigera is known to infest high value crops, including corn, cotton, and tomato. The larvae feed mainly on the flowers and fruit of the crops. See datasheet for a list of preferred hosts.
Approved Method(s)
Several screening aids for H. armigera adults and larvae are available on the CAPS Resource and Collaboration website, https://caps.ceris.purdue.edu/screening-aids.
See "Search IDaids" for additional identification tools: https://idtools.net/idAids/searchResults.cfm?searchString=helicoverpa+armigera&searchType=1
Helicoverpa armigera and the native, abundant species, Helicoverpa zea look very similar. Helicoverpa zea is attracted to the H. armigera lure and is commonly found in H. armigera traps. Dissection is required to distinguish these two species.
