Beetles Deployed to Battle Maine's Invasive Forest Pest

Maine's battle against the invasive hemlock woolly adelgid has intensified, with the Midcoast region now serving as the primary front. This tiny, sap-siphoning insect, originating from East Asia, has spread significantly, bypassing quarantines and lacking natural predators in New England. Its presence leads to the death of eastern hemlock trees, with infestations creeping further inland towards the state's western hemlock belts.

In response, a coalition of land trusts, private landowners, and the Maine Forest Service is deploying a biological control: predatory beetles. Species like *Laricobius nigrinus* and *Laricobius osakensis*, which prey on the adelgid in their native lands, are being released. These beetles, carefully vetted for safety, are introduced to infested areas like Wiscasset's Sortwell Memorial Forest in hopes of reducing adelgid populations.
