COCONUT RHINOCEROS BEETLE GUAM MANUAL

Further genetic analysis shows that CRB populations can be divided into a number of clades that coincide with the endemic and invasive history of the beetle. CRB-G from Guam was not susceptible to OrNV infection by oral delivery, but injection of the virus did cause mortality.

A team of scientists and students from the University of Guam, Tokyo University of. PCR analysis shows that OrNV is generally present at high incidence in established populations of CRB, but is generally absent from the invasive CRB-G populations. 25 Dislike Share Pacific Community 13.7K subscribers A new strain of coconut rhinoceros beetles called the CRB-G or Coconut Rhinoceros Beetle Guam Type (CRB-G) is destroying. It has been 16 years since the coconut rhinoceros beetle, or CRB, was first discovered in Guam. The female adult oviposits in and larvae feed on dead and decaying organic materials 16.

We have found that all of these outbreaks have been caused by a previously unrecognized haplotype, CRB-G, which appears to be tolerant to OrNV. Introduction Coconut rhinoceros beetle (CRB) is a devastating pest of the economically important coconut (Cocos nucifera L.). Coconut rhinoceros beetle (CRB), coconut beetle, rhinoceros beetle, palm rhinoceros beetle, Asiatic rhinoceros beetle Type of Pest Beetle Taxonomic Position Class: Insecta, Order: Coleoptera, Family: Scarabaeidae Reason for Inclusion in Manual Suggestion from CAPS Community Figure 1. Guam’s established population of non-native coconut rhinoceros beetle (CRB, Oryctes rhinoceros L.) began creating burrows in stem apices of several cycad species in a managed garden. Subsequently, new invasions have been reported from Port Moresby, Papua New Guinea (2009) O'ahu, Hawai'i (2013) and Honiara, Solomon Islands (2015). Surprisingly, a highly damaging outbreak was reported from Guam (2007), which could not be controlled by OrNV. The coconut rhinoceros beetle (CRB Oryctes rhinoceros) is a major pest of coconut and oil palm, but the discovery and release of Oryctes rhinoceros nudivirus (OrNV) in the 1960s and 70s suppressed the pest such that no new invasions of uninfested islands by CRB were reported for over 30years after implementation of the biocontrol programme.
