Japanese beetle is a pest of concern for several western states including Colorado. The adult form of the pest is a scarab beetle. Larvae, or grubs, reside in the soil. The insect feeds on roots, leaves and flowers of many landscape ornamental and agricultural plants. Japanese beetle is the target of quarantines restricting interstate shipment of nursery stock and soil TO California, Nevada, Utah, Oregon, Washington, New Mexico, Arizona, Idaho, Montana, Colorado and British Columbia, Canada. Several western states restrict movement of nursery stock and soil FROM Colorado.
