Complete mitochondrial genomes of the Perilla leaf moth, <i>Pyrausta phoenicealis</i> (Hübner, 1818) (Lepidoptera: Crambidae)

The Perilla Leaf Moth, <i>Pyrausta phoenicealis</i> (Hübner, 1818), is a polyphagous pest often confused with <i>P. panopealis</i> due to morphological similarity. Here, we report the complete 15,281-bp mitochondrial genome of <i>P. phoenicealis</i>, comprising 37 genes and one A + T-rich region. The genome exhibits typical Lepidopteran features, with a <i>trnM-trnI-trnQ</i> arrangement and a CGA start codon for <i>COI</i>. Among Pyraustinae, <i>srRNA, ND4</i>, and <i>COI</i> were the most conserved genes. Phylogenetic analyses confirmed the monophyly of <i>Pyrausta</i> with strong support. This mitochondrial genome will serve as a valuable reference for future genetic and evolutionary studies.

紫苏野螟（*Pyrausta phoenicealis*，Hübner, 1818）是一种多食性害虫，因形态相似常与*P. panopealis*混淆。本研究报道了*P. phoenicealis*的完整线粒体基因组，其全长为15281 bp，包含37个基因及1个A+T富集区。该基因组具备鳞翅目（Lepidoptera）典型的线粒体基因组特征，包含trnM-trnI-trnQ基因排列模式，且细胞色素C氧化酶亚基I（COI）的起始密码子为CGA。在螟蛾亚科（Pyraustinae）类群中，核糖体小亚基RNA（srRNA）、NADH脱氢酶亚基4（ND4）及COI为最为保守的基因。系统发育分析结果证实了*Pyrausta*属的单系性，且支持强度极高。该线粒体基因组将为后续的遗传学与进化生物学研究提供宝贵的参考资料。
