Scale feeding allows infection by the Neonectria fungus. The largest trees are most susceptible. What is happening in Michigan? Beech bark disease is the result of the combined effects of a non-native scale insect and a canker fungi. Biology and Management of Beech Bark Disease The disease was first discovered in Ohio in 2012. Beech bark disease has continued to spread through much of Quebec, northern Pennsylvania and, most recently, northeastern West Virginia. Here is a brochure of the 11 most invasive forest pests and pathogen species that threaten WV. Additionally, red perithecia (sexual fruiting bodies) of the Neonectria fungi can be seen exuding from bark tissues, and a very limited number of the woolly beech scale can also be found.

Some of these include Beech Bark Disease, Chestnut Blight, and Butternut Canker. As large areas of bark are affected, the tree is girdled and killed. Bark: The bark is smooth, thin, and gray in color even on the largest stems. BBD is caused by a fungal pathogen that doesn't attack trees until they have been extensively infested with a non-native scale insect.The sap feeding scale insects, in combination with the Neonectria fungus, causes BBD. The beech’s shade tolerance and its sprouting abilities, combined with beech bark disease, make the beech a rather despised tree these days among foresters. It has been spreading rapidly since its initial detection in Northeast Ohio in 2012. BLD causes defoliation, dieback, and eventual mortality in affected trees. The scale insect feeds on the beech tree sap, opening wounds in the tree for the fungus to start colonizing the bark, cambium layer, and sapwood of the tree (OFAH/OMNR Invading Species Awareness Program, 2012).
