IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.

Lure Notes:

9/14/17: The combination of lures for Tetropium fuscum is also effective for T. castaneum. If Tetropium fuscum is listed as a survey target in a work plan, then T. castaneum must also be listed in the work plan. All three lures listed are necessary to trap for this species. The release rates of these lures are 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.
