| 【目的】自2003年Paul Hebert等提出DNA条形码（DNA barcoding）概念以来，直翅目昆虫DNA条形码与分子系统进化领域取得了令人瞩目的成就。【方法】本文通过对2003-2023年间中国知网（CNKI）、Web of Science核心合集数据库（WoSCC）、Scopus和PubMed数据库中收录的直翅目类群利用DNA条形码进行物种鉴定及系统发育研究相关文献进行检索，共检索到1 386条数据，整理去重复后最终得到849条有效数据，并使用可视化软件CiteSpace 6.3.R1（64-bit）Advanced对关键词、作者、研究机构、发文国家等信息进行可视化分析。【结果】直翅目昆虫DNA条形码及分子系统进化研究的年发文量整体呈上升趋势，2021年发文量高达75篇。国内陕西师范大学黄原教授和法国国家自然历史博物馆（Museum National d'Histoire Naturelle，MNHN）Robillard Tony教授在该领域贡献尤为显著，发文量分别高达41篇和43篇，为DNA条形码在直翅目物种鉴定中提供了珍贵材料、理论基础及方法创新。【结论】在过去的20年时间里，直翅目昆虫系统学研究逐渐深入至近缘种间及种下水平。DNA条形码在其中扮演着重要角色，促使研究从单一的形态学特征转向多种分子数据（单基因片段、多基因联合、线粒体基因组等）相结合的研究方法。这丰富了进行物种鉴定及物种界定的研究方法，有利于更全面地分析直翅目昆虫的系统发育关系。 |

| 【Aim】 Since the introduction of DNA barcoding by Paul Hebert and colleagues in 2003, significant advances have been made in its application to orthopteran insects for molecular species delimitation and phylogenetics.【Methods】This study conducted a comprehensive literature search across multiple databases, including CNKI, Web of Science Core Collection (WoSCC), Scopus, and PubMed, covering the period from 2003 to 2023. We initially identified 1 386 records related to DNA barcoding in orthopteran taxonomy and phylogenetics. After thorough deduplication and screening, 849 relevant publications were retained for analysis. Using CiteSpace 6.3.R1 Advanced (64-bit), we performed a visual analysis of keywords, authors, institutions, and countries.【Results】The results revealed an general upward trend in annual publications output, peaking at 75 articles in 2021. Professor Yuan Huang from Shaanxi Normal University and Professor Tony Robillard from the Muséum National d'Histoire Naturelle (MNHN) were identified as the most prolific contributors, with 41 and 43 publications, respectively. Their work has provided substantial data, theoretical insights, and methodological innovations for orthopteran DNA barcoding.【Conclusion】Over the past two decades, systematic research on Orthoptera has progressively deepened to encompass both interspecific and intraspecific relationships. DNA barcoding has been instrumental in this evolution, facilitating a shift from purely morphological approaches to integrative methodologies that combine various molecular data types. This integration has significantly enriched the toolkit for species identification and delimitation, thereby enabling a more comprehensive understanding of orthopteran phylogeny. |
