Bark beetles: A natural and dramatic forest disturbance

Projects Posted on: September 29, 2015
A number of native bark beetles can cause tree mortality in western forests and urban environments. These insects have co-evolved over thousands of years with their host trees and are an integral part of forest ecosystems. Researchers are conducting numerous studies to better understand beetle’s ecological role in shaping forest composition and structure.

The flight periodicity, attack patterns, and life history of Dryocoetes confusus Swaine (Coleoptera: Curculionida: Scolytinae), the western balsam bark beetle, in north central Colorado

Dryocoetes confusus Swaine, the western balsam bark beetle, is an important bark beetle associated with Abies lasiocarpa (Hook.) Nutt. (subalpine fir) in western North America. Little information is available on the life cycle and ecology of this insect in Colorado. In this study in north central Colorado, we examined its flight periodicity, attack patterns, and life cycle in downed trees.
