“…In Malaysia, bacterial pathogens ( B. thuringiensis and P. popilliae ) in combination with OrNV and Metarhizium sp. produced 88% mortality of third instar CRB larvae ( Kamarudin et al 2007 ). Two indigenous strains of nematodes from India, S. carpocapsae and H. indica , significantly increased larval mortality in neonates and third-instar larvae in compost heaps ( Patil et al 2014 ).…”

“…If quarantine facilities are not available in the region of introduction, collaboration with international partners may be needed to complete the risk assessment and provide sufficient information to determine the agent’s suitability. Finally, the potential for competition between the new agent and other pre-existing control agents, particularly OrNV and Metarhizium, should be investigated before a new agent is released ( Gopal and Gupta 2002 , Kamarudin et al 2007 ).…”

“…from O’ahu, Hawaii also caused first-instar larval mortality after 2–7 d of exposure ( Manandhar et al 2020 ). While B. thuringiensis and P. popilliae have demonstrated some potential to infect CRB ( Babu et al 1971 , Kamarudin et al 2007 ), there are no suitable products available commercially ( Table 1 ). Therefore, identifying local entomopathogenic species may provide opportunities to develop local industries that produce biopesticides.…”

The coconut rhinoceros beetle (CRB: Oryctes rhinoceros Linnaeus) is one of the most damaging pests to coconut and oil palms in Asia and the Pacific Islands. Adults bore into the crown and damage developing fronds, which affects tree development and yield. The insect is native to South and Southeast Asia and was inadvertently introduced into the Pacific in 1909. It has since spread to several Pacific island nations and territories, causing significant economic impact on these important coconut and palm-growing regions. In the 1950s and 1960s, an international biological control effort was initiated to search for and release natural enemy species. Release of the Oryctes rhinoceros nudivirus Huger (OrNV) and the species complex of Metarhizium Sorokin (Hypocreales: Clavicipitaceae) was successful in controlling CRB in its invaded range. Recently a new biotype of the beetle, known as CRB-G, has spread into the Pacific Islands causing unprecedented levels of damage due to the failure of previously successful biological control agents (BCAs) to suppress this biotype. The re-emergence of CRB as a serious pest warrants a rigorous re-evaluation of potential BCAs and a new search for effective natural enemies if necessary. In this article, we review literature on CRB to 1) analyze past introductions of BCAs and their effectiveness; 2) identify potentially important natural enemies and their geographical origins; and 3) assess possible approaches for utilization of BCAs against the new wave of CRB invasion. Research gaps and directions deserving future attention are highlighted and a strategy for renovation of biological controls for CRB suggested.

“…Pheromone trapping has been used successfully in the past to indicate and monitor the presence of CRB in Malaysia (Chung 1997;Kamarudin et al 2007) and India (Saminathan et al 2019), and also provide a relative estimate of abundance (Southwood 1978;Grant 1991). The aim of the current study was to assess the spread and abundance of CRB in the outbreak zone by establishing and monitoring a network of pheromone traps during parts of 2017-18 and 2019-2020.…”

An invasive population of the coconut rhinoceros beetle (Oryctes rhinoceros; CRB) was discovered in Honiara, Guadalcanal, Solomon Islands in 2015. The beetle has caused severe damage to coconut palms in the outbreak area and its continued spread threatens the food security and livelihood of thousands of smallholder farmers in the region. Spread and abundance of the beetle were monitored using bucket traps baited with the aggregation pheromone, ethyl-4 methyloctanoate. Beetles were collected from traps approximately bi-weekly for two periods; one during 2017–18 and the other during 2019–2020. Trap catches showed that CRB was present throughout the whole survey region with significantly higher numbers of female CRB trapped than males. Results indicate a significant 1.5-fold increase in CRB trap catch numbers from 2017–2018 to 2019–2020 despite control efforts. The number of CRB adults trapped also varied between sites and months during both time periods but with no clear patterns. Removal of breeding sites along with strong local quarantine should remain the top priority of the local government to contain CRB expansion within Solomon Islands and beyond.

The Incidence and microbial natural enemies of Oryctes spp. (Coleoptera: Scarabaeidae) in date palm orchards in Al-madinah Almunwarah region, were studied. The different date palm cultivars can be arranged in descending order according to the infestation severity with Oryctes spp. as follow: Ajwah > Rothan > Safawi > Helwah > Shalabi > Barni and Rabbiah. The highest infestation rates of date palms with rhinoceros beetles were reached 44.1, 42.2 and 37.7% in September, August and November respectively. Whereas, the lowest infestation was recorded in February (10.2%) and January (11.7%). The population density decreased to reach the minimum values by mid January. The dominant stage of development occurred was the third larval instar. The first and second instars were rarely encountered. The vertical distribution of adults and immatures of the rhinoceros beetle around the heaps and root of the date palm was also studied. Data revealed that adults were more abundant in the surface layer at depth of 0:30 cm than immatures. While, immature stages were the most dominant at 30-60 cm depth. There were 72.3% of immatures (larvae and pupae) population found in the middle layer at depth (30:60 cm) around roots. In comparison, the third depth layer included only 5.3 % adults and 16.3% immatures. Four microbial natural enemies were recorded as mortality factors associated with the larval and pupal stages sampled within date palm orchards. The microbial analysis was narrowed down to detect only entomopathogenic fungi (Beauveria bassiana and Metarhizium anisopliae), bacteria (Bacillus spp.), and virus (Oryctes virus). Entomopathogenic fungi caused average mortality to Oryctes larval population reached 15.3% and 9.2% by Beauveria bassiana and Metarhizium anisopliae, respectively. In comparison both entomopathogenic fungi caused 6.5% pupal mortality. On the other hand, Bacillus spp. caused the highest larval mortality reaching up to 39.2%, compared to 3.3% to pupae. Whereas, the percentage of infected larvae and pupae with virus recorded 27.6% and 11.5%, respectively and it was higher than of both pathogenic fungi (24.5%).
