New Zealand Entomologist Fights Beetle in New Caledonia

Why this is here: Researchers collected as many as 80 beetle specimens in less than one week to analyze their genetic makeup and determine the specific strain.

New Zealand entomologist Trevor Jackson recently completed a mission in New Caledonia to assist with controlling the coconut rhinoceros beetle. He collaborated with scientists from the Southern Province, the IAC, and the Dumbéa living river association.

The team captured up to 80 beetle specimens within a week for genetic analysis. Researchers aim to identify the beetle strain—one found on the main island and another on Lifou—to determine the best biological control method.

New Zealand’s AgResearch has funded similar missions in Asia, Latin America, and other Pacific nations. They maintain a collection of CRB virus strains to test for effectiveness in each new location. The team releases virus-infected beetles to control the rhino beetle population.

New Caledonia’s scientists are currently investigating potential harm to native species from introducing these biological controls. Funding for this project extends to September 2026, with potential support from France’s national biodiversity office and a partnership between the IAC and the Southern Province.
