Cold nemesis of tiny pest.

Hemlock forests across the state will benefit from this winter's stretches of sub-zero cold, according to researchers. The reason being, is that the bitter cold kills the hemlock's adversary, the hemlock woolly adelgid, a tiny insect pest.

Kenneth Gooch, Forest Health Program supervisor for the Department of Conservation and Recreation, collects 10 sample branches of Hemlock woolly adelgid on Hemlock trees at Wells State Park in Sturbridge, in upper right photo. Mr. Gooch noted that the last time temperatures dipped so low, roughly 80 percent of the adelgid population was killed off. Wells State Park in Sturbridge has significant adelgid activity, he noted, and the state has released beetles there to keep the insect pest under control.

Mr. Gooch uses a hand lens to look at hemlock woolly adelgids on a hemlock tree branch at the park, far left photo.
