Beetles released in Allegheny National Forest to combat invasive insect

The U.S. Forest Service announced the release of additional beneficial insects in the Allegheny National Forest to combat the non-native, invasive hemlock woolly adelgid.
Hemlock woolly adelgid is an invasive insect native to Japan and the Pacific Northwest. The adelgid poses a serious threat to eastern and Carolina hemlock, which are at risk of fatal infestations since they lack natural resistance.
