The Asian longhorned beetle (Anoplophora glabripennis) is known to damage 34 species of trees, including poplars, several species of maple, paper birch, willows, and elms. It is considered a “quarantine” pest in the U.S. and Europe and has caused significant economic losses there and in Asia. Females can lay between 30 and 178 eggs under the host plant’s bark, and the larvae feed on the phloem and sap-containing wood of the host tree, causing damage to the central and upper trunk and main branches.
