This page is intended as a depository for information on an infestation of the coconut rhinoceros beetle (CRB), Oryctes rhinoceros, at Tumon Bay, Guam. CRB is a serious pest of palms. An eradication plan has been prepared with the goal of eliminating the threat of massive economic and environmental damage by this newly arrived invasive species.
An environmental impact assessment for the Guam rhinoceros eradication project is available here.

- September 11, 2007 An adult female beetle was collected by Aldrin Manapat and James Thomas Hollingsworth and given to Brent Tibbatts, Division of Aquatic & Wildlife Resources (DAWR), Guam Department of Agriculture. Identified as Oryctes rhinoceros by A. Moore, University of Guam (UOG).
- September 13, 2007 Brent Tibbatts & Renee Franquez from DAWR, and Aubrey Moore & Bob Bourgeois from UOG visited the collection site. No adult beetles were found, but feeding damage was seen on a nearby coconut growing on a vacant lot (13.50879N 144.80061E); 28 grubs were removed from a 2 m coconut stump beneath the damaged palm; a second coconut with feeding damage was found nearby (13.50774N 144.79942E).
- September 14 - 18, 2007 Delimiting survey; infestation extends from the Hilton north along the beach until Fujita Rd.; feeding damage observed on many trees at the Fiesta Hotel; See Google Earth image of Tumon Bay above; If you have Google Earth installed on your computer, click here to view the data interactively.
- September 19, 2007 Grubs were detected at Gun Beach by Ben Quichocho and Patrick Artero of the Guam Plant Inspection Station (13.52416N 144.80399E and 13.52428N 144.80405E).

- September 28, 2007 A landscaper phoned to report that he had found what appear to be CRB feeding burrows in three palm trees he had just transplanted. Fortunately, the source and destinate of these plants was within the known infested area of Tumon Bay. This report is evidence that CRB can be accidentally dispersed by landscapers and the plant nursery industry.
