Barrier Pitfall traps and tree brands were used to sample adult carabid beetles in five forest stands of different tree species composition and spruce budworm infection levels. twenty genera and 37 species were collected over the two year period. Adult carabid populations were highest in the red spruce stand while carabid species diversity was greater in hardwood or fir stands having the most tree diversity. Potential adult carabid predators of spruce budworm were identified using 5 criteria; number of individuals, seasonal abundance, habitat preferences, size, and food.
