Plain Language Summary
Introductions of some forest insects from other continents can result in important economic, environmental and ecological impacts. One approach used by the Canadian Food Inspection Agency to improve the detection of these species is to collect logs from trees in declining health at high risk sites of introduction and to incubate them to obtain insects, if present. Adults of an alien wood-boring beetle, Trichoferus campestris (no official common name) emerged, and live larvae were extracted from a log taken from a dying Norway maple in Mississauga, Ontario. In its native range, eastern Asia, this beetle attacks healthy and slightly stressed hardwoods and conifers of many species. Until this discovery, there was no host record in North America although larvae of this beetle had been intercepted many times in wood packaging material. Adults had also been captured in trap installed at various sites in North America. The feeding damage done by this beetle suggests this insect is not a primary pest of trees in Ontario.
