ARS Research News - U.S. National Arboretum Offers Solution to Hemlock Woolly Adelgid Pest
- Feb 23, 2023
- USDA. Agricultural Research Service.
- Hemlocks in the U.S. are vulnerable to attack by a small insect called the hemlock woolly adelgid (HWA). This insect looks like tiny cotton balls on the needles of the tree and can kill the trees by feeding on the sap. The adelgid has decimated stands of hemlocks in the eastern U.S. While insecticides and biological control measures can offer some relief, the best way to combat HWA is to develop genetic resistance in the trees.
