WHAT WE ARE UP TO:

Ashley Spaur releasing Cyphocleonus the "Knapweed Root Weevil" in Enterprise, OR today! This insect can safely be considered "The King" of Spotted Knapweed biocontrol. A lareg conspicuous insect, it lays its eggs on the top of the knapweeed's root crown. After the eggs hatch, the larvae burrow into the root. This larval feeding destroys knapweeds vascular root tissue and prevents the plant from transporting water and nutrients. Roots become swollen and deformed as a result of this larval feeding. Death of the plant can occur within two years!
