Next generation of pine beetles threatening North America

The most destructive pest to North America's mature pine forests, the mountain pine beetle, is threatening the next generation.

A study conducted by a University of Alberta researcher shows that the pine beetle not only kills adult trees, but can also leave the next generation of pine vulnerable.

"The next pine forest is at risk," said Justine Karst, an assistant professor in restoration ecology at the U of A, and co-lead author of the study with Nadir Erbilgin, Canada research chair and associate professor in forest entomology and chemical ecology.
