As growing spruce budworm populations continue to fluctuate in Maine, the Maine Forest Service, University of Maine Cooperative Forestry Research Unit (CFRU), and our cooperator network are tracking populations carefully in anticipation of an approaching outbreak.

A comprehensive spruce budworm (SBW) monitoring program requires a multi-pronged approach. It relies on using methods such as pheromone trapping, light trapping, overwintering L2 larval sampling, and both ground and aerial survey. At the core of the Maine Forest Service (MFS) monitoring program lies the extensive pheromone trap network throughout western and northern Maine's spruce-fir forests. A permanent pheromone trap network was first established …

The last SBW outbreak during the 1970s–80s grew quickly, killed millions of acres of spruce-fir stands, and cost the region’s economy many hundreds of millions of dollars. Although it is not possible to predict exactly when defoliation of balsam fir and spruce will begin, how severe the next outbreak will eventually become, or how long it will …
