COCONUT RHINOCEROS BEETLE (Oryctes rhinoceros)

What and Why?

Eradication of an invasive species becomes less likely and control costs increase as an invasive species spreads over time. Our goal is to add dogs as a detection tool to existing efforts for bio-security, early detection, eradication and monitoring in the main Hawaiian islands.

About CRB

According to the Coconut Rhinoceros Beetle Response, CRB was first detected on O'ahu in December of 2013. Native to Southeast Asia, adult CRB feed on emerging palm fronds, causing damage that can often be severe enough to kill the plant. CRB populations can have devastating impacts on palm species that are foundational to cultural heritage, agriculture, ecosystems, and economies, when out of their native range. in 2023, CRB was detected on Kaua‘i.

Where?

Our CRB program is based on Kaua‘i. An intensive training program was conducted from May through November 2025. The dog teams completed their certifications in November and have begun conducting field surveys.
