Effect of Ecosystem Disturbance on Diversity of Bark and Wood- Boring Beetles (Coleoptera: Scolytidae, Buprestidae, Cerambycidae) in White Spruce (Picea glauca (Moench) Voss) Ecosystems of Alaska

Data from 15 years of field work on the effects of ecosystem disturbance on populations of wood-boring beetles (Buprestidae and Cerambycidae) and bark beetles (Scolytidae) are summarized. Twenty-eight species of cerambycids were caught in upland sites compared to 21 species in flood-plain sites; 12 species of buprestids were caught in the upland sites and 8 species in the flood-plain sites. Twenty species of scolytids were found in the upland sites and 21 species in flood-plain sites. Species lists of insect and vegetation are provided by site and length of time after disturbance.
