In an effort to protect the trees of Ohio, the Ohio Department of Agriculture (ODA) is encouraging Ohio citizens to check their trees for signs of the Walnut Twig Beetle and Asian Longhorned Beetle. The Walnut Twig Beetle is a small beetle known to carry a fungus that causes Thousand Cankers Disease (TCD), which can kill walnut trees. Walnut Twig Beetle was first confirmed in Ohio in late 2012 in traps set by Ohio Department of Natural Resources Division of Forestry officials in Butler County. Additionally, scientists from the Ohio Plant Diagnostic Network, a cooperative partnership between ODA and The Ohio State University, recently isolated the TCD fungus from walnut branch samples from the Butler County area, marking the first time TCD has been confirmed in Ohio.
