Asian longhorn beetle eradicated from Toronto, Mississauga

The Asian longhorned beetle (ALHB) has been eradicated from the cities of Mississauga and Toronto in the province of Ontario. This was the only known population of ALHB in Canada. ALHB is a highly destructive wood-boring pest of maples and other hardwood trees including poplar, birch and willow. It has the potential to devastate Canada’s hardwood and maple syrup industries.

The ALHB was discovered in the cities of Mississauga and Toronto in August 2013, after previously having been eradicated in the cities of Toronto and Vaughan. To prevent the spread, CFIA established a regulated area within the cities of Mississauga and Toronto that restricted the movement of nursery stock, trees, lumber, wood, and wood products, including all firewood unless given prior authorization. Combined with a promotional campaign creating awareness about the movement of firewood, CFIA with the help of residents and businesses were successful in eradicating this destructive invasive species.

After five years of surveys with no detection of this plant pest, the Asian Long-horned Beetle Infested Place Order has been repealed effective June 9, 2020. The movement of firewood and host tree materials will no longer be restricted, however it is important to remember that one of the most common ways pests travel is by hitching a ride in firewood. It is always recommended to buy and burn wood locally.

As Canada marks the United Nations International Year of Plant Health, each Canadian has a critical role to play in protecting Canada’s plants and trees against pests such as the Asian longhorned beetle.
