Characterization of mitochondrial genome and phylogenetic implications for Chinese black ant, Polyrhachis dives (Hymenoptera: Formicidae).

Chinese black ant, Polyrhachis dives Smith, also known as P. vicina Roger has been used as a traditional edible insect and Chinese medicine in China and some southeast countries for thousands of years. In this study, Mitogenome of this species was assembled with high coverage using Illumina sequencing data and is 15,806 bp long in size. The base composition is 37.8% for A, 12.5% for C, 6.4% for G and 43.3% for T. The mitogenome contains 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The phylogeny showed that it was closely related to Camponotus atrox (Hymenoptera: Formicidae) with high bootstrap value supported. The mitogenome of P. dives can provide essential DNA molecular data for further phylogenetic and evolutionary analysis.

Complete mitochondrial genome of Simao pine caterpillar moth, Dendrolimus kikuchii (Lepidoptera: Lasiocampidae) and the related phylogenetic analysis.

Dendrolimus kikuchii, the Simao pine caterpillar moth is an economically important forest pest causing great damage to coniferous trees in south China. The whole mitogenome for the moth was sequenced using next-generation sequencing technology. The moth has a total length of 15,422 bp in mitogenome size. The nucleotide composition is biased toward adenine and thymine, accounting for 79.2%: A = 40.7%, T = 38.5%, G = 8.1%, and C = 12.7%. The phylogeny showed that D. kikuchii was closely grouped with D. punctatus, D. tabulaeformis, Euthrix laeta, and Trabala vishnou guttata to form the monophyletic clad for the Lasiocampidae family of Bombycoidea superfamily with strong nodal support.
