The rednecked cane borer, Agrilus ruficollis (F.), is a buprestid beetle that infests wild and cultivated blackberries and raspberries in the eastern states from Canada to the Gulf of Mexico. Adults are about 6-7 mm (1/4 inch) long, with an iridescent coppery pronotum. A related species, Agrilus rubicola, may occur concurrently. This species is uniform in color, ranging from copper-colored to iridescent green. On galled plants, there is less live vegetative growth and more dead wood. There is often reduced berry size and number, as well as vegetative growth with increasing number of galls per plant. Affected canes may not produce fruit. Canes weakened by galls are more subject to winter injury.
