June 25, 2020 - Ottawa, ON. If the Asian longhorned beetle establishes itself in Canada, a wide range of social activities that depend on healthy hardwood forests could be impacted, such as hiking, camping, and fall-colour tours. To date, 15 states, British Columbia, and Ontario have reported ALB interceptions (City of Toronto, 2015). According to Ellison et al. From 2004-2007, an additional 40 infested trees were detected and removed each year, less than 15 infested trees were found in 2007, and no infested trees were found for the remainder of the surveys (NRCAN, 2011). Its scientific name is Anoplophora glabripennis (Motchulsky) (Coleoptera: Cerambycidae). ALB in its adult form is a has a black body, blue-white bands on long antennae (the “horns”), blue leg bands, and a starry sky pattern of white spots of various sizes on its wing casings. 2009b). Th… he Asian longhorned beetle is a large wood-boring beetle native to China and other Asian countries. Long, black antennae, one to two times its body length. In 2002, Asian longhorned beetle was found in New Jersey and has since spread to Toronto, Ontario, and eastern Massachusetts. Long, black and white banded antennae, one to two times its body length. The photo shows a pupa inside a tree. It currently infests areas in Massachusetts, New York and Ohio. Asian Longhorned Beetle: Pupa. being among the most ecologically and economically significant. There are restrictions on the movement of nursery stock, trees, logs, lumber, wood, wood chips and bark chips from trees identified as potential hosts of the ALB and firewood of all species in the regulated area (see map below). Image. When prevention is not possible, ‘early detection and rapid response’ is advocated as the best strategy to combat an introduced invasive species.

In Ontario, full development of ALB populations has been observed on maples (Acer spp. The Asian longhorned beetle (ALHB) has been eradicated from the cities of Mississauga and Toronto in the province of Ontario. Many susceptible trees around the infested areas were removed in hopes of stopping the spread of the beetle. In addition, another 12,500 nearby trees that were considered susceptible to infestation were also cut down and chipped (NRCan, 2014). Insecticides do not protect trees; trees must be cut down and burnt or chipped. The beetle chews its way into hardwood trees to lay eggs. Never moving firewood, nursery stock, or other tree materials outside of regulated areas. In Canada, the adult ALB can easily be mistaken for several native beetles that look similar, such as the white-spotted sawyer (Monochamus scutellatus). Single eggs will be laid at multiple sites, with the possibility of one female laying up to 100 eggs. This is best exemplified in the case of the Asian longhorned beetle (ALB). Although ALB has not been found in Wisconsin, it currently infests areas in Massachusetts, New York, Ohio and Ontario, Canada. Adults are 2 – 4cm (¾ – 1½ inches) in length. ALHB is a highly destructive wood-boring pest of maples and other hardwood trees including poplar, birch and willow. Asian Long-horned Beetle. ALB was detected in the Toronto, Ontario area in 2003 and quick action lead to eradication of the pest over the following years. Early Detection & Distribution Mapping System. With no current cure, early identification and eradication are critical to its control. Ongoing monitoring efforts are now on-going to ensure this infestation has been contained (, OFAH/OMNR Invading Species Awareness Program, 2012, D-11-05 – Phytosanitary Requirements for Non-Manufactured and Non-Propagative Wood Products to Prevent the Introduction from the Continental United States and Spread Within Canada of the Asian Long-horned Beetle, Anoplophora glabripennis (Motschulsky), D-02-12 – Import requirements of non-manufactured wood and other non-propagative wood products, except solid wood packaging material, from all areas other than the continental United States, D-01-12 – Phytosanitary Requirements for the Importation and Domestic Movement of Firewood, D-98-08 – Entry Requirements for Wood Packaging Materials Produced in All Areas Other Than the Continental United States, Survey Guidelines for Asian Longhorned Beetle (, Lignes directrices pour les enquêtes sur le longicorne asiatique (.

Asian longhorned beetle (ALHB) has been eradicated from the cities of Mississauga and Toronto in the province of Ontario. For example, in the City of Toronto, 42% of the street trees are preferred host species for the beetle and thus susceptible to its attack (City of Toronto, 2015). The Asian Longhorned Beetle (Anoplophora glabripennis) was introduced from Asia to the U.S. with the first breeding populations found in NY State in 1996 (USDA).It is a wood-boring pest that attacks maples and other hardwood trees.
