White Pine Weevil

The White Pine Weevil is considered the most destructive pest of the eastern White Pine. Although it has other common hosts such as Colorado Blue Spruce, Norway and Serbian Spruce, and sometimes Douglas Fir. This pest is small and rust colored with patches of brown and white scales on the front wings and the adult has a long snout like beak. The Larvae live beneath the bark and are white with a distinct brown head. The First sign of attack is glistening droplets of resin on the terminal leaders. Most damage is done by the larvae from May through June. They chew and burrow completely around the stem causing the current years wilt, droop, and eventually die.  Application of a pesticide should be made from late March through April when the droplets of resin are first detected.
