tiny insect is damaging Vermont’s
hemlock trees. The hemlock wooly adelgid eats the trees and subsequently kills
them. And there’s no known enemy of the insect, until now. Researchers have been releasing a type of beetle that
feeds exclusively on adelgids to try to stem their spread.
Vermont’s trees face a host of challenges from invasive
diseases and insects, human development and climate change. One of the insects
that has made its way into southern Vermont is the hemlock wooly adelgi.
The recent discovery of an insect that destroys hemlock trees is causing some alarm in southern Vermont. Now, researchers are hoping to halt the spread of the hemlock woolly adelgid by introducing an adelgid-eating beetle.
The recent discovery of hemlock woolly adelgid in
a sixth Windham County town is bad news for
the region’s forests. The insects have devastated hemlocks in areas
south of New
especially Appalachia. But scientists have reasons to hope the damage
could be less severe here.
