Variants in the mitochondrial genome sequence of Oryctes rhinoceros (Coleoptera: Scarabaeidae) infected with Oryctes rhinoceros nudivirus in oil palm and coconut plantations.

The CRB (coconut rhinoceros beetle) haplotype was classified into CRB-S and CRB-G, based on the presence of single nucleotide polymorphisms (SNPs) in the mitochondrial cox1 gene. Mitochondrial genomes (mitogenomes) are the most widely used genetic resources for molecular evolution, phylogenetics, and population genetics in relation to insects. This study presents the mitogenome CRB-G and CRB-S which were collected in Johor, Malaysia.

Complete Genome Sequences of Oryctes rhinoceros Strains Detected in Haplotype-G Oryctes rhinoceros from Johor, Malaysia.

Two members of the species Oryctes rhinoceros (OrNV) were detected in haplotype G beetles collected from an oil palm plantation in Kluang and a wild coconut tree in Batu Pahat (Johor, Malaysia). OrNV strain Kluang comprised 125,794 bp, encoding 125 open reading frames (ORFs), while OrNV strain Batu Pahat comprised 124,925 bp, encoding 126 ORFs.
