10 years ago the Coconut Rhinoceros beetle (CRB) was first discovered on the western Pacific island of Guam. Since then, these shoe-shine black, miniature invaders have spread to all parts of the island and are laying waste to the local coconut and oil palm population. The economy, culture and ecology  of Guam and other Pacific islands are intrinsically linked to the native palm species such that the rhino beetle poses a major threat. The indigenous peoples of Guam have a long history of weaving palm fronds, an artistry that is now at risk due to the rhino beetle. These trees are a symbol of tropic paradise, a motif that drives Guam’s primary industry; tourism. Continue reading

The project was implemented in coordination with the Abu Dhabi Food Control Authority (ADFCA) and will run throughout the rest of 2013 and 2014. This project aims to control palm tree pests while minimising pesticide usage, by increasing the knowledge and capabilities of workers to enable them to implement the best control methods for pests.

It takes a large combined effort to successfully eradicate a plant pest. The Guam Coconut Rhinoceros Beetle Eradication Project has finally found a technique that could bring them their own eradication success story. The coconut rhinoceros beetle (Oryctes rhinoceros) was first discovered in Guam on 11th September 2007. Over the past five years it has caused severe damage to coconut palms, although its initial spread was slowed by the quick reactions of the government. It is now present in many parts of the island and, as coconuts are an important economic commodity for the US territory, is high priority for removal. Continue reading
