摘　　要：夜蛾科是鳞翅目中物种数量最多的科。夜蛾科的一些蛾类昆虫是作物上的重要害虫。然而,目前缺乏夜蛾科中文夜蛾亚科的线粒体基因组序列。本研究以标瑙夜蛾为代表,报道了文夜蛾亚科第1个线粒体全基因组序列。标瑙夜蛾的线粒体基因组全长为15,430 bp,包含13个蛋白质编码基因、2个核糖体RNA基因和22个转运RNA基因以及1个非编码控制区。本文使用夜蛾科中的60个物种为内群研究对象,并选取2个尾夜蛾科昆虫作为外群,分别使用最大似然法和贝叶斯法构建夜蛾科的系统发育关系。系统发育树显示,金翅夜蛾亚科、青夜蛾亚科、实夜蛾亚科、冬夜蛾亚科、夜蛾亚科、Ipimorphinae和文夜蛾亚科为单系群,而盗夜蛾亚科、木夜蛾亚科、剑纹夜蛾亚科和杂夜蛾亚科为非单系群。本研究旨在通过对线粒体基因组数据的分析,研究夜蛾科中各亚科之间的系统发育关系,并阐明标瑙夜蛾的系统发育地位。The Noctuidae is the largest family within the order Lepidoptera.Many species of moths in Noctuidae are known to be significant pests for crops.However,there is currently a lack of available mitochondrial genome sequences for the subfamily Eustrotiinae,a clade within the Noctuidae.In this study,we report the first complete mitochondrial genome from the subfamily Eustrotiinae,represented by the species of Maliattha signifera.The mitochondrial genome of M.signifera is 15,430 bp in length and contains 13 protein-coding genes,two ribosomal RNA genes,22 transfer RNA genes,and one non-coding control region.We conducted phylogenetic analyses using maximum likelihood and Bayesian inference methods,with 60 exemplars of Noctuidae as ingroups and two species of Euteliidae as outgroups.The phylogenetic trees show that the subfamilies Plusiinae,Bagisarinae,Heliothinae,Cuculliinae,Noctuinae,Ipimorphinae,and Eustrotiinae form the monophyletic groups,while the subfamilies Hadeninae,Xyleninae,Acronictinae,and Amphipyrinae are found to be non-monophyletic.The aim of this study is to explore the phylogenetic relationship among subfamilies within Noctuidae and clarify the phylogenetic placement of M.signifera through analysis of mitochondrial genome data.
