重建强大的系统发育框架是了解许多经济重要分类群的生态和进化的关键。玉米螟属（Ostrinia）是一种多源性农业害虫，由于其特征缺乏，种间形态界限不清，其分类和系统发育一直存在争议。为了解决这些问题，我们推断的分子遗传学的奥斯特里尼亚使用一个包含498个位点和115 197个核苷酸位点的基因组数据集，并检查是否传统的形态特征证实了我们的分子结果。我们的研究结果强烈支持的单系性的鸵鸟属物种组之一，但令人惊讶的是不支持的单系性的其他两个。基于广泛的形态学检查和广泛代表性的分类单元采样的基因组分析，我们提出了一个修订的分类属，定义为三个种组（Ostrinia nubilalis种组，Ostrinia obumbratalis种组和Ostrinia penitalis种组），这与Mutuura和Munroe（1970）的传统分类不同。形态学和分子证据揭示了一个新的北美物种的存在，多刺奥斯特里亚杨sp.n.，与O. obumbratalis。我们的分析表明，该虫的祖先幼虫对双子叶植物有较强的寄主选择性; nubilalis（欧洲玉米螟）和Ostriniapericacalis（亚洲玉米螟）独立地进化出对以单子叶植物为食的偏好（即，玉米）。一些鸵鸟属物种的雄性有扩大的，有凹槽的中腹部，有刷子的器官，可以吸引雌性在求偶过程中增加交配成功率，这可能代表了一种衍生的条件。我们的研究为这种农业上重要的昆虫谱系提供了一个强有力的进化框架。
Reconstructing a robust phylogenetic framework is key to understanding the ecology and evolution of many economically important taxa. The crambid moth genus Ostrinia contains multiple agricultural pests, and its classification and phylogeny has remained controversial because of the paucity of characters and the lack of clear morphological boundaries for its species. To address these issues, we inferred a molecular phylogeny of Ostrinia using a phylogenomic dataset containing 498 loci and 115 197 nucleotide sites and examined whether traditional morphological characters corroborate our molecular results. Our results strongly support the monophyly of one of the Ostrinia species groups but surprisingly do not support the monophyly of the other two. Based on the extensive morphological examination and broadly representative taxon sampling of the phylogenomic analyses, we propose a revised classification of the genus, defined by three species groups (Ostrinia nubilalis species group, Ostrinia obumbratalis species group, and Ostrinia penitalis species group), which differs from the traditional classification of Mutuura & Munroe (1970). Morphological and molecular evidence reveal the presence of a new North American species, Ostrinia multispinosa Yang sp.n., closely related to O. obumbratalis. Our analyses indicate that the Ostrinia ancestral larval host preference was for dicots, and that O. nubilalis (European corn borer) and Ostrinia furnacalis (Asian corn borer) independently evolved a preference for feeding on monocots (i.e., maize). Males of a few Ostrinia species have enlarged, grooved midtibiae with brush organs that are known to attract females to increase mating success during courtship, which may represent a derived condition. Our study provides a strong evolutionary framework for this agriculturally important insect lineage.
