The complete mitogenome of Parapoynx crisonalis (Walker, 1859) (Lepidoptera: Crambidae), with phylogenetic relationships amongst three acentropine larval forms

ABSTRACT

The larvae of Parapoynx crisonalis (Walker, 1859) is an important pest in China, causing significant damage on the aquatic crops. To improve the management of P. crisonalis and demonstrate the phylogenetic relationships amongst Pyraloidea, the complete mitochondrial genome (mitogenome) sequences of four aquatic pyralid moths, which belong to three acentropine larval forms – Parapoynx-type, Nymphula-type and Potamomusa-type, and twenty-three terricolous pyralids were compared. The complete mitogenome P. crisonalis, a typical parapoynx larval species, was 15,374 base pairs in length and included 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and an A + T-rich region. The phylogenetic analysis revealed that all the aquatic acentropine moths formed a monophyletic clade with strong phylogenetic support via maximum likelihood and Bayesian methods with a bootstrap value of 100% and a posterior probability of 1.00. The Potamomusa-type was more closely related to the Nymphula-type than to the Parapoynx-type.
