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).
Method Notes:

Traps should be placed in hardwood stands with minimal amounts of coniferous species. This will limit the number of the non-target species, Trypodendron lineatum, (a pest of conifers) that are collected. In addition, compounds released by conifers (i.e., alpha-pinene) can act as a repellent to this beetle. In 2012, the wet collection cup method will be the only method approved for use with multi-funnel (Lindgren) traps.


Approved Lure(s)
NAPIS Code Product Dispenser Effectiveness Compound(s)
24 Lineatin Lure flex tube 84 days lineatin
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 screening aids and a reference collection. Use the appropriate screening aid for your geographical area.
Use the screening aid by Humble (n.d.) to differentiate from native Trypodendron species.
Mistaken Identities:

Other Scolytinae. Large numbers of the similar-looking, native species, Trypodendron lineatum, are drawn to the same lure used to trap T. domesticum.
