Cane Borers

The adult red-necked cane borers, Agrilus ruticollis (Fabricius), can be identified by the reddish section (thorax) behind their head; the rest of the body is black. Characteristic injury caused by these borers is a swelling of the cane that can be from 1/4 to 3 inches long and can occur at any place on the cane. The cane usually is weakened or breaks off at the swelling.
