NATURAL ENEMIES AND INSECT ASSOCIATES OF THE MOUNTAIN PINE BEETLE, DENDROCTONUS PONDEROSAE (COLEOPTERA: SCOLYTIDAE), IN SUGAR PINE

Abstract

AbstractThe mountain pine beetle, Dendroctonus ponderosae, and 68 associated insect species were reared from infested sugar pine, Pinus lambertiana. Portions of three infested trees were sectioned by height and the insects emerging from each were identified and recorded. In one tree the number of woodpecker strikes also was noted. The tops of two of the three trees were infested by another bark beetle, Pityophthorus confertus, and from these same two trees the most common parasite obtained was Macromesus americanus.
