随着下一代测序方法的出现，近年来，系统发育学出现了新的转折。系统基因组学是系统发育学与基因组数据的结合，已成为研究物种系统学和进化的有力工具。最近，利用系统基因组学工具进行的突破性研究为昆虫进化的时间和模式提供了更好的见解。昆虫学家现在越来越多地使用下一代测序方法来生成各种昆虫物种和品系的基因组和转录序列。这些数据为比较基因组学和昆虫不同谱系的大规模多基因系统发育提供了机会。系统基因组学研究帮助我们更好地了解昆虫物种的系统和进化关系，这些物种在草食动物、捕食性动物、有害动物、传粉者或疾病媒介中发挥着重要作用。重要的是，我们必须批判性地评估系统学方法的前景和局限性。在这篇综述中，我描述了昆虫系统学研究的现状，概述了主要的挑战，并对系统发育学工具在昆虫系统学和进化研究中的潜在应用进行了评论。
With the advent of next-generation sequencing methods, phylogenetics has taken a new turn in the recent years. Phylogenomics, the integration of phylogenetics with genome data, has emerged as a powerful approach to study systematics and evolution of species. Recently, breakthrough researches employing phylogenomic tools have provided better insights into the timing and pattern of insect evolution. The next-generation sequencing methods are now increasingly used by entomologists to generate genomic and transcript sequences of various insect species and strains. These data provide opportunities for comparative genomics and large-scale multigene phylogenies of diverse lineages of insects. Phylogenomic investigations help us better understand systematic and evolutionary relationships of insect species that play important roles as herbivores, predators, detritivores, pollinators, or disease vectors. It is important that we critically assess the prospects and limitations of phylogenomic methods. In this review, I describe the current status, outline the major challenges, and remark on potential future applications of phylogenomic tools in studying insect systematics and evolution.
