Pine Wilt Nematode and Mountain Pine Beetle Along the Front Range: Is There a Connection?

We've received several samples in the Diagnostic Clinic this month of Scots pine that have been hit with Mountain Pine Beetle (MPB) from areas along the front range and one of those samples also had Pine Wilt Nematode (PWN) (Bursaphelenchus spp.). So we are asking ourselves, which came first, MPB or PWN? And, is one exacerbating the other? To see if we can answer this question, we are collecting samples of MPB hit Scots pine that are being cut down in counties along the Front Range to process for PWN to see if there is any correlation. The specific counties we would like samples from are Larimer, Weld, Boulder, Adams, Jefferson, Denver, Arapahoe and Douglas. The samples should be from trees no higher than 6000 ft elevation. The samples should be collected from branch areas closest to the trunk and should be no more than 3 inches in diameter and about 6-8 inches in length. Samples will be processed at no charge to the submitter. Samples should also be sent within 1-2 days of the tree being cut down. Samples can be sent to the Plant Diagnostic Clinic, E215 Plant Sciences Bldg, Colorado State University, Fort Collins, CO 80523-1177. If you have any questions, feel free to call us at 970-491-6950.

  1. It's pretty interesting. They're using wood from the westbank first nations for the olympic podiums....
