Control Methods for the Boxwood Narrow Jewel Beetle

In recent years in the Nantong area, large-leaf boxwood has been found to die off, initially in scattered patches and gradually developing into large areas of dieback.

The large-leaf boxwood narrow jewel beetle belongs to the order Coleoptera, family Buprestidae, genus Agrilus.
