Fighting Bugs with Bugs

December 9, 2022 - By Cory Swift-Turner, Communications Specialist Eastern hemlock (Tsuga canadensis) is a coniferous tree that favors the cool and humid climate along the Appalachian Mountains. Hemlocks can grow more than 150 feet tall and live for more than 800 years. Their short, dense needles provide excellent habitat for many kinds of wildlife, from warblers to bobcats. Unfortunately, healthy hemlocks are becoming increasingly rare. In the early 1950s, an invasive insect called... Read More

Deadly Jewels of Virginia Forests

June 9, 2022 - By Amanda Conrad, DOF Forest Health Technician The vibrant, metallic green of an emerald ash borer (EAB) makes it look like royalty of the forest. But this beautiful, invasive insect is also deadly. Just one beetle can lay 40-70 eggs on the bark of its preferred host: ash trees. The growing larvae disrupt the flow of water throughout the tree, which will ultimately kill the tree. A healthy ash tree... Read More

Sounding the Fire (Ant) Alarm!

May 26, 2022 - By Katlin Dewitt, DOF Forest Health Specialist Can a fire alarm alert you to an invasive insect?

In Virginia, this species was first detected in 1989, and so... Read More

Thinning Out Southern Pine Beetle

April 7, 2022 - By Katlin Dewitt, DOF Forest Health Specialist The southern pine beetle (SPB) is the most destructive native insect that threatens pine forests in the Southeast. These tiny insects, about the size of a grain of rice as adults, are especially harmful due to the complex system of pheromones (insect “scents” that are specific to a species) they utilize to find host trees and aggregate. Pheromones allow populations to build up... Read More

The Vine That Ate Charlottesville

September 29, 2021 - By Ellen Powell, DOF Conservation Education Coordinator I know what you’re thinking. But no, the vine that ate Charlottesville isn’t kudzu. It’s porcelain-berry (Ampelopsis brevipedunculata). You might know this species as an ornamental vine, often seen spilling over pergolas in fancy gardens. It’s great for covering a bare patch of ground or an unsightly old shed. The fruits are quite beautiful, with pale green, lavender, magenta, and blue berries often... Read More
