The hemlock woolly adelgid is a non-native invasive species that threatens both eastern and Carolina hemlocks. This species was accidentally introduced from Japan in the 1950s and has since become established throughout much of the native range of both hemlock species. A small sapsucking insect, this pest feeds during the winter and depletes stored nutrient reserves within the tree, and can cause mortality in heavily infested trees. In this presentation, you will learn about the biology and control options available for hemlock woolly adelgid. Our presenter, Katlin DeWitt, is a Forest Health Specialist with the Virginia Department of Forestry.
