BACKGROUND/OBJECTIVES: , class Insecta, order Lepidoptera, superfamily Noctuoidea, family Erebidae, and subfamily Arctiinae, is a polytrophic agricultural pest. However, there are still many sequences missing for Arctiinae from mitochondrial whole-genome sequences.
In this study, we determined and analyzed the complete mitochondrial genome sequence of . Furthermore, based on the sequencing results, we used the Bayesian inference, maximum likelihood, and maximum reduction methods to analyze the phylogenies of 18 species of the Hypophora subfamily.
The mitochondrial genome was found to be a circular double-stranded DNA with a length of 15,380 bp and included 13 protein-coding genes (PCG), 22 tRNA genes, 2 rRNA genes, and one control region. With the exception of , all the tRNA genes could form conventional clover structures. There were 23 intergenic spacer regions with lengths of 1-52 bp and six gene overlaps with lengths of 1-8 bp. The control region was located between and genes and comprised 303 bp and an AT content of 74.25%.
The results showed that is closely related to . Our results suggest that Syntomini is phylogenetically distinct from Arctiini and may warrant separate tribal status within Arctiinae. This study is dedicated to researching the mitochondrial genome and phylogenetic relationships of , providing a molecular basis for its classification.
背景/目的： ，昆虫纲鳞翅目夜蛾总科灯蛾科苔蛾亚科，是一种多食性农业害虫。然而，苔蛾亚科线粒体全基因组序列仍有许多缺失。
在本研究中，我们测定并分析了 的完整线粒体基因组序列。此外，基于测序结果，我们使用贝叶斯推断、最大似然法和最大简约法分析了苔蛾亚科18个物种的系统发育。
发现线粒体基因组是一个长度为15380 bp的环状双链DNA，包含13个蛋白质编码基因（PCG）、22个tRNA基因、2个rRNA基因和一个控制区。除 外，所有tRNA基因都能形成常规的三叶草结构。有23个基因间隔区，长度为bp，6个基因重叠区，长度为1 - 8 bp。控制区位于 和 基因之间，长度为303 bp，AT含量为74.25%。
结果表明 与 密切相关。我们的结果表明，苔蛾族在系统发育上与灯蛾族不同，可能有理由在苔蛾亚科内获得独立的族级地位。本研究致力于研究 的线粒体基因组和系统发育关系，为其分类提供分子依据。
