Curculionidae -- Control -- Northwest, Pacific. Borers (Insects) -- Control -- Northwest, Pacific. Poplar -- Diseases and pests -- Northwest, Pacific.
Poplar-and-willow borer larvae burrow into stems of all ages of poplar; their galleries weaken the bole and limbs of infested plants, causing them to break when stressed by high winds. There are no chemicals available to professional integrated pest management (IPM) personnel to control this pest. Professionals need to be able to identify the pest species, avoid using infested cutting for propagation, use properly timed harvest, and recommend long-term management strategies to minimize losses to poplar-and-willow borer infestations.
