Developing Verbenone as a Semiochemical Tool to Suppress Mountain Pine Beetle

Rob Progar, Ph.D. Research Entomologist, Pacific NW Research Station

Chris Fettig, Ph.D. Research Entomologist, Team Leader, Pacific SW Research Station with contributions from (Retired) USFS, Steve Munson

The last outbreak of mountain pine beetle affected more than 27 million hectares of forest in western North America. This outbreak enabled further development of the smiochemical verbenone, a compound discovered in the late 1960’s that is the antiaggregant for mountain pine beetle. Verbenone send the signal “this tree is unsuitable for further colonization and to seek another host”. We will discuss recent research to further develop verbenone as a management tool for mountain pine beetle and new products resulting from this work.
