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.

A test of high-dose verbenone for stand-level protection of lodgepole and whitebark pine from mountain pine beetle (Coleoptera: Curculionidae: Scolytinae) attacks

Publications Posted on: May 21, 2013
The effcacy of verbenone as a stand-level protectant against mountain pine beetle, Dendroctonus ponderosae Hopkins, attacks was tested in lodgepole and whitebark pine stands at five geographically separated sites, including three consecutive years at one site. Forty and 20 high-dose pouches, with a verbenone emission rate up to 50 mg/d per pouch, were spaced in a grid pattern throughout 0.40-ha plots, replicated up to six times at each site.
