Survey

Approved Method(s)
Method Detail NAPIS Survey Method
Trap 107 - Multi-funnel Trap, 12 Funnel, Wet 3001 - General Trapping Procedure
Trap 105 - Multi-funnel Trap, 8 Funnel, Wet 3001 - General Trapping Procedure
Trap Spacing:
When trapping for woodborers or bark beetles, separate traps with different lure combinations by at least 30 meters (98 feet).
Method Notes:

Likelihood of Establishment Map A Likelihood of Establishment Map is now available. This survey should only be considered in the states with appropriate weather 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 PERAL. The SAFARIS team used a weather suitability model for European spruce bark beetle occurrence in the continental United States, which was developed by PPQ PERAL and NCSU CIPM, to support CAPS survey planning. The model predicts the suitability of an area for European spruce bark beetle occurrence based on the likelihood of favorable weather conditions for the insect occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.


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:

Attaching lures to traps

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 weather 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.
Key Diagnostic or Identification

Approved Method(s)
ID/Diagnostic:
Morphological: Examine specimens under a good quality, high powered (preferably with up to 90X) dissecting microscope, with the help of a reference collection. Use screening aid for relevant geographical area.
Mistaken Identities:

Other Scolytinae In the Northeastern U.S.: Ips avulses, Ips perroti, Ips perturbatus, Ips pini, and Ips plastographus.
