HONOLULU – Coconut rhinoceros beetle (CRB) grubs have been found at a residence in Waikoloa Village on Hawai‘i Island. This is the first discovery of the invasive beetle on the island.

On Oct. 11, 2023, the resident found five large grubs (larvae) in a decaying palm tree stump on the property and reported it to the Coconut Rhinoceros Beetle Response Project. Staff from the Hawai‘i Department of Agriculture (HDOA) responded to the site and collected the specimens which were sent to a University of Hawai‘i laboratory in Honolulu where a DNA-based test was used to identify the grubs as CRB. On Wednesday of this week, the resident reported finding one more grub on the property. No other grubs or adult CRB have been detected so far on Hawai‘i Island.

HDOA crews on Hawai‘i Island and CRB response staff from O‘ahu have surveyed the immediate area and have not found additional CRB damage. A multi-agency team will continue to survey the area. Additional pheromone traps, used for early detection of infestations, are being deployed from Waikoloa Beach to Waimea, as well as other areas around the island. Surveillance for CRB has been ongoing on all islands, including traps at airports, harbors and other strategic locations. HDOA staff are also trying to trace the origin and the pathway of the grubs found in Waikoloa.

Residents are encouraged to go to the CRB Response website at:  https://www.crbhawaii.org/ to learn more about how to detect the signs of CRB damage, how to identify CRB life stages, and how to report any suspected signs of damage or beetles/grubs via the CRB reporting feature. Reports of possible CRB infestation may also be addressed to the CRB Response team at (808) 679-5244, email [email protected] or the state’s toll-free Pest Hotline at (808) 643-PEST (7378).

CRB grubs live in decomposing plant and animal waste and may have been inadvertently transported across O‘ahu and to neighbor islands in bags of compost or mulch. Adult CRB prefer to feed on coconut and other larger palms, and are a major threat to the health of these plants.

Residents on all islands are asked to be vigilant when purchasing mulch, compost, and soil products, and to inspect bags for evidence of entry holes. Adult beetles are about 2-inches long, all black and have a single horn on their head.

The CRB is a large scarab beetle that was first detected on O‘ahu in 2013. The beetle has since been detected in many neighborhoods on O‘ahu, and was detected on Kaua‘i in May 2023 where collaborative eradication efforts continue. Last week, several agencies were involved in the pesticide treatment of palm trees via drones at a Kaua‘i golf course. More than 90 palm trees were treated and 40 adult CRBs were killed. Additional treatment efforts will continue on Kaua‘i. Last month, a dead adult CRB was found in a compost bag at a Maui big-box store. No other CRB have been detected on Maui.

CRB is a serious pest of palm trees, primarily coconut palms, as the adult beetles bore into the crowns of the palms to feed on the tree’s sap. New unopened fronds are damaged in this way and when fully opened, may break and fall unexpectedly. If CRB kill or damage the growing point of the palm, the tree may die. Secondary fungal or bacterial pathogens may also attack the wounds caused by CRB, thereby killing the tree as well. Tree mortality after CRB attack has been reported to be anywhere from 10 percent to 50 percent. Dead trees then become a safety hazard as they may fall unexpectedly after the trunk rots, potentially resulting in bodily injury or property damage.

CRB is a major pest of palms in India, the Philippines, Palau, Fiji, Wallis, Nukunono, American and Western Samoa and Guam. It is still not known exactly how the beetles arrived in Hawai‘i.
