Improved traps for the coconut rhinoceros beetle (Oryctes rhinoceros)

The coconut rhinoceros beetle (CRB), a major pest of coconut and other palms, was first detected on Guam Island in 2007 and on Oahu Island, Hawaii in 2013. On Guam, mass trapping using CRB aggregation pheromone, ethyl 4-methyloctanoate, was ineffective for population control. Recent improvements have increased trap catch rates by more than an order of magnitude. These improvements include equipping pheromone traps with solar powered ultraviolet light emitting diodes and mounting the traps on steel drums containing artificial breeding sites.
