Raspberry Cane Borer: There are no chemical treatments registered for management of this insect.
Management Hints: This longhorned beetle attacks canes of roses about eight inches below the tip, causing the leaves to wilt and the stem to droop. The larval stage bores down the cane to the base, where pupation occurs. Prune and destroy infested canes below the affected area.
