Aggregation pheromone of coconut rhinoceros beetle,Oryctes rhinoceros (L.) (coleoptera: Scarabaeidae) [PDF]

Journal of Chemical Ecology, 1995
Male coconut rhinoceros beetles,Oryctes rhinoceros (L.), produce three sex-specific compounds, ethyl 4-methyloctanoate, ethyl 4-methylheptanoate, and 4-methyloctanoic acid, the first of which is an aggregation pheromone. Synthesis of these compounds involving conjugate addition of organocuprates to ethyl acrylate is reported.

Complete genome sequence of Oryctes rhinoceros nudivirus isolated from the coconut rhinoceros beetle in Solomon Islands [PDF]

Virus Research, 2020
Oryctes rhinoceros nudivirus (OrNV) has been an effective biocontrol agent against the insect pest Oryctes rhinoceros (Coleoptera: Scarabaeidae) for decades, but there is evidence that resistance could be evolving in some host populations.

Removal of heavy oil using rhinoceros beetle, Oryctes rhinoceros

Journal of Environmental Management, 2019
The remnant of heavy oil, often expressed as total petroleum hydrocarbons (TPHs), in soil and/or sludge is commonly encountered by and often ruins the habitat of some indigenous insects. Recent studies indicate that some of the insects could stand the impact and some not just survived but might serve as an oil degrader.

Efficacy of botanical formulations against coconut rhinoceros beetle oryctes rhinoceros

Indian Journal of Entomology, 2022
Field efficacy of botanical cakes and insecticides when evaluated in coconut against the rhinoceros beetle Oryctes rhiniceros L., revealed that leaf damage reduced to 9.5% with botanical cake and paste. Palms treated with chlorantraniliprole 0.4% GR (10.5%) and neem cake admixed with sand (11.5%) were also effective compared to control (40.0%) at 30 ...

A new haplotype of the coconut rhinoceros beetle, Oryctes rhinoceros, has escaped biological control by Oryctes rhinoceros nudivirus and is invading Pacific Islands

Journal of Invertebrate Pathology, 2017
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 ...

A mathematical model of invasion and control of coconut rhinoceros beetle Oryctes rhinoceros (L.) in Guam

Journal of Theoretical Biology, 2023
The coconut rhinoceros beetle (CRB), is one of the most damaging pests to coconut palms causing severe economic harm. Its expansion from Asia to the Pacific in the early 20th century has been stopped by virus control. However, a new haplotype CRB-Guam has recently escaped this control and invaded Guam, other Pacific islands, and has even established ...

Damage assessment of Oryctes rhinoceros Beetle (Oryctes rhinoceros Linn) and its host range in selected sites in the Philippines

International Journal of Science and Technology Research Archive, 2023
The study was conducted to determine the extent of damage and host range of O. rhinoceros in different coconut areas in the Philippines. Using the five criteria based on Bedfort assessment, at least 50 coconut palms in one hectare were randomly selected and replicated three times from selected provinces in Luzon, Visayas and Mindanao.

Control of the coconut pest Oryctes rhinoceros L. using the Oryctes virus

International Journal of Tropical Insect Science, 2001
The coconut palm is an important plantation crop in India, where it is cultivated on 1.796 million hectares. The rhinoceros beetle, Oryctes rhinoceros L. (Coleoptera: Scarabaeidae) is a serious pest of coconut throughout India and southeast Asia, causing an estimated 10% yield loss in the crop.

Properties of the nucleocapsids of a virus isolated from Oryctes rhinoceros

Virology, 1977
Abstract Nucleocapcids were isolated from purified particles of “ Oryctes ” virus (a candidate Baculovirus ) by treatment with Nonidet P-40. The nucleocapsids were homogeneous in size and density and contained the viral DNA as well as eight of the twelve virus particle polypeptides resolved on polyacrylamide gels.
