Résumé en langage clair et simple

The hemlock woolly adelgid (Adelges tsugae) is an introduced pest of hemlock trees in eastern Canada and the eastern United States. Hemlock woolly adelgid is also present in British Columbia but is a native species there and not a significant pest. The insect causes damage by eating the contents of a tree’s nutrient storage cells. This reduces the health of trees and causes buds to die and needles to turn yellow. Tree death can occur in 5-15 years after a tree is infested. This publication describes the biology, impact and management options for hemlock woolly adelgid in Canada.
