Abstract

Oenopia sauzeti Mulsant are predators of various aphids, such as Myzus persicae, Rhopalosiphum maidis, and Sitobion avenae. We sequenced the mitochondrial genome (mitogenome) of O. sauzeti. Consistent with other mitogenomes of Coleoptera, the circular mitogenome of O. sauzeti consists of 17,630 bp, including 13 PCG genes, 2 rRNA genes, and 22 tRNA genes. The mitogenome differs in 2 long non-coding regions of 1285 bp and 1843 bp. The 22 tRNA genes products are folded into the typical cloverleaf secondary structure, except trnS1, which lacks the dihydrouridine (DHU) arm. The base composition is AT-biased (80.1%). The phylogenetic tree confirms monophyly at the genus level within the Coccinellinae and supports O. sauzeti as a sister group to Aiolocaria hexaspilota.

摘要

Oenopia sauzeti Mulsant 是各种蚜虫的天敌，例如桃蚜、Rhopalosiphum maidis和Sitobion avenae。我们对O. sauzeti的线粒体基因组（有丝分裂基因组）进行了测序。与鞘翅目的其他有丝分裂基因组一致，O. sauzeti的环状有丝分裂基因组由 17,630 bp 组成，包括 13 个 PCG 基因、2 个 rRNA 基因和 22 个 tRNA 基因。有丝分裂基因组的不同之处在于 1285 bp 和 1843 bp 的 2 个长非编码区。22个tRNA基因产物折叠成典型的三叶草二级结构，trnS1除外，缺少二氢尿苷 (DHU) 臂。基础成分是 AT 偏向的 (80.1%)。进化树确认单系在Coccinellinae和支持中属一级O. sauzeti为姐妹群Aiolocaria hexaspilota。
