Survey
Trap Spacing:
When trapping for woodborers or bark beetles, separate traps with different lure combinations by at least 30 meters (98 feet).
Approved Lure(s)
| NAPIS Code | Product | Dispenser | Effectiveness | Compound(s) | 26 | Ips sp. Lure, 3 Dispenser | polysleeve or bubble cap | 56 days | cis-verbenol |
|---|---|---|---|---|
| polysleeve or bubble cap | 56 days | ipsdienol |
||
| polysleeve or bubble cap | 56 days | 2me-3-buten-2-ol |
Lure Attachment:
IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.
Lure Notes:
The release rate of this lure is highly temperature-dependent. However, CAPS has listed a conservative length of effectiveness that will be effective for even the warmest climates in the CAPS community.
Survey Recommendations
The following are recommendations for executing the survey using the approved methods for pest surveillance. The recommendations are developed through literature review and consultation with subject matter experts.
Climate Suitability Map:
A Climate suitability map is now available. This survey should only be considered in the states with appropriate climate 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.
