Sutherlin FFA

Hosts: Douglas fir and true firs

Infestation Characteristics: Occasionally infest recently planted Douglas fir seedlings that have found to be J-rooted during planting or have very poor shoot-to-root ratios. Trees that are heavily infested have a swollen appearance in the vicinity of larval wounds. Damage to seedlings and young trees usually occur on the main stem.

Control: Clipping and destroying infested branches before June will aid in reducing weevil numbers.
