Coconut rhinoceros beetle (CRB) continues to spread to new areas on Oʻahu. Our current detections map shows increased beetle populations in central Oʻahu, west Oʻahu, and new detections on the North Shore.
CRB can fly up to 2 miles at a time, but it is the movement of larvae in breeding material that causes new population establishment. Most population expansion occurs when infested material is moved from a high-risk area to a low-risk area. Report suspected beetles, larvae, tree damage, and the movement of potentially infested material to the CRB Response at 808-679-5244.
