Plain Language Summary

Discovery of the non-native Anoplophora glabripennis Motschulsky (Coleoptera: Cerambycidae) in Ontario, Canada, in 2003 led to the implementation of an eradication program. The plan consisted of removing all infested trees and all trees within 400 m of an infested tree belonging to a genus considered suitable for complete development of this wood-borer; however, many of the trees within that 400 m belonged to genera for which suitability for development of A. glabripennis was questionable or unknown. We visually inspected over 3000 such trees annually for the 3 y following removal of infested trees. All but one tree were unattacked: an ash (Fraxinus excelsior L. (Oleaceae)) tree had signs of oviposition and early-instar development, but not of adult emergence. Prior to that survey, we had found only one other species with questionable suitability, a little leaf linden, Tilia cordata Mill. (Malvaceae). That tree had many signs of oviposition, but no evidence of full development, suggesting resistance to A. glabripennis. Both these trees were within 200 m of the most heavily-infested maple (Acer platanoides L. (Sapindaceae)) tree found in that infestation suggesting that colonisation of trees with questionable or unknown suitability might occur mostly where population pressure is high.
