Lures and a pest hotline for reporting infestations are a step toward finding and eliminating this new North American destructive pest.©īeetle Identification Butterfly Identification Caterpillar Identification Spider ID Fungal Infections on Insects Nursery Web Spider Official State Insects Termite Basics Insect Molting Process Bugs of Tennessee House Other Pacific islands infested with the exotic beetle have used deliberate fungal and viral infections to kill adults and stop breeding. Efforts to find, control and, hopefully, eradicate it from the island are now underway. Exactly how the beetle arrived on the island is still unclear. The beetle has now been found on the island of Oahu in the state of Hawaii. It has done significant damage to coconut tree populations there. The Coconut Rhinoceros Beetle is native to Asia, but migrated to the Pacific Island of Guam sometime in 2007. The yellowish grubs are also large, growing up to 4 inches long. Coconut Rhinoceros Beetles are pests on a variety of other common island plants such as pineapples, bananas, papayas, dates and taro. This frond damage reduces coconut production and could kill younger trees. It then drinks the sap that is released by the plant's soft tissue. It bores holes into the young, upper fronds of coconut palm trees. An adult male has large horns while a female has smaller, shorter horns. ![]() The hefty Coconut Rhinoceros Beetle is large and black. ![]()
