A task force formed to eradicate the beetle only got a fraction of the. Native to Southeast Asia, adult CRB feed on emerging palm fronds, causing damage that can often be severe enough to kill the plant. The state Department of Agriculture says the beetle was first spotted in Hawaii in 2013 at the Mamala Bay Golf Course. A new genetic testing method offers a faster way to identify it using egg, larvae, or excrement samples. The coconut rhinoceros beetle (CRB), Oryctes rhinoceros, was first detected on Oahu in December of 2013.

Thus far, the infestation has been restricted to Oahu.Īmong the restrictions, potential host material coming from quarantine areas must be completely enclosed or covered with a secure lid during transport to an approved green waste disposal site.įor more information, contact the state at (808) 679-5244 or email go to CRB Response webpage at or the HDOA Plant Pest Control Branch New Pest Advisory at. The coconut rhinoceros beetle (Oryctes rhinoceros), an invasive pest in Hawaii, is difficult to differentiate from oriental flower beetle (Protaetia orientalis) until its adult stage. Search assisted by beetles, equipped with radio. More than 3,000 beetle traps have been placed throughout Oahu to detect infestations, the department said. CRB detector dog teams are currently deployed by the Hawaii CRB Eradication Program on the Island of Oahu. Infestations have also been detected on the North Shore, from Mokuleia to Kahuku. ![]() The beetle (Oryctes rhinoceros) represents a serious threat to palm trees, primarily coconut palms, as adult beetles bore into crowns of palms to feed on tree sap, the department said in a news release.įirst detected in 2013 at Joint Base Pearl Harbor-Hickam, the beetle has since been found in West Oahu areas - from Maili to Pearl City and north to Kunia. ![]() ![]() The Hawaii Department of Agriculture last week issued an interim rule aimed at restricting movement of the beetle’s “host material” - trees, green waste, compost, mulch, trimmings, fruit and vegetative scraps and decaying stumps of palm and palm-related plants - on Oahu as well as from Oahu to neighbor islands. New restrictions are in place on the transport of certain palm trees and green waste that may be infested with the coconut rhinoceros beetle.
