The Coconut Rhinoceros Beetle (Oryctes rhinoceros) was first detected in Hawaii in December 2013. This invasive pest is native to Southeast Asia. It attacks coconut palms by boring into the crowns or tops of the tree where it damages growing tissue and feeds on tree sap. The damage can significantly reduce coconut production and kill the tree. The beetle is also known to feed on economically important commercial crops such as bananas, sugarcane, papayas, sisal, pineapples, and date palms.

What You Can Do













What You Can Do

  • Look for bore holes and V-shaped cuts on palm fronds.

  • Inspect mulch and compost piles for beetle larvae. Beetles lay eggs in dead, standing palms and decaying organic material, such as compost and sawdust piles, then larvae feed on rotting material until they emerge as adults.

  • Allow authorized agricultural specialists access to your property to look for the beetle and possibly hang a trap.

  • In Hawaii, call the Hawaii Department of Agriculture’s Pest Hotline if you suspect you’ve found the coconut rhinoceros beetle: (808) 643-PEST (7378).

  • In other states, report sightings of this pest at HungryPests.com.

  • Declare all agricultural items when you return from international travel.

  • Do not bring or mail fresh fruits or vegetables, or living plants unless agricultural inspectors have inspected and cleared them beforehand.
