Ontario to face new and old pest threats in 2014

An invasive species of insect that has devastated hemlock forests in the northeastern seaboard of the U.S. has made its way into Ontario.

 It’s the hemlock woolly adelgid, a native of Japan.

 “It’s a small sap-sucking insect about the size of an aphid,” explained Taylor Scarr, provincial forest entomologist with the Ontario Ministry of Natural Resources.
