Survey

Approved Method(s)
Method Detail NAPIS Survey Method
Trap 105 - Multi-funnel Trap, 8 Funnel, Wet 3001 - General Trapping Procedure
Trap 107 - Multi-funnel Trap, 12 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).

Approved Lure(s)
NAPIS Code Product Dispenser Effectiveness Compound(s)
27 Pityogenes chalcographus Lure centrifuge tube 56 days chalcogran
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. In 2012, the wet collection cup method will be the only method approved for use with multi-funnel (Lindgren) traps.


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.
