The complete mitochondrial genome of Ceutorhynchus obstrictus (Marsham, 1802) (Coleoptera: Curculionidae)

Abstract

Ceutorhynchus obstrictus (Marsham, 1802) is a serious pest of oilseed rape (Brassica napus L.) in Europe and the USA. We have determined a 20,124 bp mitogenome of C. obstrictus which includes 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a single large non-coding region of 2,773 bp. The base composition was AT-biased (81.4%). Hypothetical ORFs are identified in the control region. Phylogenetic trees present that C. oibstricus is clustered with Alcides juglans (Alcidinae). It also shows polyphyletic manner for two tribes, requiring more mitogenomes to resolve it.
