Project Partners: University of Minnesota, U.S. Forest Service
Project Period: 7/1/2014 – 6/30/2017
Mountain pine beetle has been previously found in Minnesota through the importation of western pine logs. Although the insects were not alive, the demonstration of this pathway lead to the regulation of western pine logs into Minnesota.
The University of Minnesota and U.S. Forest Service are evaluating how the biology of mountain pine beetle may be different in Minnesota than in its native range in western North America. The Minnesota Department of Agriculture (MDA) is surveying the state for possible introductions.
The MDA is surveying for the mountain pine beetle using pheromone-baited traps in areas where the risk of establishment is greatest in northern Minnesota. Our survey is aimed at detecting low-level populations of mountain pine beetle that may have previously gone unnoticed. Populations of species new to an area typically exist at low levels for a period of time before growing rapidly and expanding.
In each of the three years of the project we have monitored 100-125 traps at 25 sites. Sites where traps have been placed have been adjusted from year to year to cover the greatest amount of area with the survey. 2016 trapping is ongoing, but no mountain pine beetle were found in 2014 or 2015. MDA also monitored traps for mountain pine beetle in 2013 as a pilot project before the work funded through the Environment and Natural Resources Trust Fund began.
