The Coconut Rhinoceros Beetle (CRB), a serious invasive pest, was detected on Dec. 23, 2013 on Joint Base Pearl Harbor – Hickam on coconut trees.

Since the detection, a joint effort between the U.S. Department of Agriculture (USDA), the University of Hawaii @ Manoa (UH), the U.S. Navy, the Hawaii Department of Agriculture (HDOA) and other partners have mobilized surveying, trapping and control efforts in the area where the beetle was found.  The Incident Command System (ICS) has been established to help manage the various agencies and activities needed to efficiently respond to this pest emergency.

CRB is a major pest of palms in India, the Philippines, the Palaus, Fiji, Wallis, Nukunono, American and Western Samoa and Guam. CRB is native to the Asian tropics, but was accidentally introduced to western and central Pacific islands. It is not known exactly how the beetles arrived in Hawaii.

CRB is mainly a pest of coconut and oil palms, but may also attack other palm species. Adult CRB are dark brown in color and measure 1 ¼ to 2 ½ inches long. CRB larvae are white in color with a brown head.

They damage palms by boring into the center of the crown where they injure young, growing tissue and feed on the sap. As they bore into the crown, they cut through developing leaves, causing damage to the fronds. V-shaped cuts in the fronds and holes through the midrib are visible as leaves mature and unfold.

Suspected CRB on coconut and palm plants on all islands should be reported to HDOA’s PEST HOTLINE – 643-PEST (7378). This is also a toll-free number for neighbor islands.
