Tree selection and use by the polyphagous xylophage Anoplophora glabripennis (Coleoptera: Cerambycidae) in Canada

Two breeding populations of the non-native Asian longhorned beetle (Anoplophora glabripennis Motschulsky), a pest broadleaf trees in its native China, were discovered Ontario 2003 and 2013, respectively. Both eradicated by removing all injured uninjured deemed at high risk injury. We used data collected during this removal to study host selection. Signs A. injury observed on 732 stems from seven (i.e., Acer, Salix, Populus, Betula, Ulmus, Fraxinus Tilia) 45 tree genera available. Complete development was confirmed only first four these genera. Most signs genus Acer with diameter 130 cm above ground ranging between 15 40 cm. On most trees, lowest sign within three meters or 40% height. Tree height explained 63% variance location Initial attacks typically near middle expanded both upward downward successive over time. discuss how findings could improve survey efforts for glabripennis.
