This resistance has proved paramount to the invasive ability of CRB. The Guam population was deemed a new biotype (CRB-Guam) and was found to be resistant to all available OrNV strains. Upon DNA analysis, the invading rhino beetles were found to be genetically distinct from CRB native to other Pacific regions. Early attempts at disseminating the virus in the new Guam population proved surprisingly ineffective. Up until Guam, 2007, it had been 40 years since an outbreak of CRB on an uninfested palm growing Pacific island, owing to the persistence of OrNV in beetle populations. As a biological control strategy, it has been highly effective at keeping CRB populations low and thus lessening palm damage by up to 90% ( Bedford, 2013). The principal method of rhinoceros beetle control is through the release of a virus specific to CRB known as Oryctes rhinocerosnudivirus (OrNV). These trees are a symbol of tropic paradise, a motif that drives Guam’s primary industry tourism.Ī coconut palm damaged by CRB © Aubrey Moore 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. 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. 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.
