|ASIAN LONG-HORNED BEETLE|
This insect native to Asia attacks healthy trees. It was first identified in North America in New York State in 1996, and appeared in Ontario in September 2003. The only means of controlling it is to cut down and burn the infested tree and all others within a 400-metre radius.
|EMERALD ASH BORER|
This pest was first reported in Michigan in 2002 and shortly afterward in Essex County, Ontario. Also native to Asia, it multiplies extremely quickly and has already caused considerable damage in our neighbouring province, where millions of ash trees have had to be destroyed.
