Plant defense compounds play a key role in the evolution of insect-plant associations by selecting for behavioral, morphological, and physiological insect adaptations. Sequestration, the ability of herbivorous insects to accumulate plant defense compounds to gain a fitness advantage, represents a complex syndrome of adaptations that has evolved in all major lineages of herbivorous insects and involves various classes of plant defense compounds. In this article, we review progress in understanding how insects selectively accumulate plant defense metabolites and how the evolution of specific resistance mechanisms to these defense compounds enables sequestration. These mechanistic considerations are further integrated into the concept of insect-plant coevolution. Comparative genome and transcriptome analyses, combined with approaches based on analytical chemistry that are centered in phylogenetic frameworks, will help to reveal adaptations underlying the sequestration syndrome, which is essential to understanding the influence of sequestration on insect-plant coevolution.
植物防御化合物通过选择昆虫的行为、形态和生理适应性，在昆虫与植物关系的进化中发挥关键作用。隔离是食草昆虫积累植物防御化合物以获得适应性优势的能力，它代表了一种复杂的适应综合征，在所有主要的食草昆虫谱系中都有进化，并且涉及各类植物防御化合物。在本文中，我们综述了在理解昆虫如何选择性积累植物防御代谢物以及针对这些防御化合物的特定抗性机制的进化如何实现隔离方面所取得的进展。这些机制方面的考量进一步融入到昆虫与植物协同进化的概念中。比较基因组和转录组分析，结合以系统发育框架为中心的基于分析化学的方法，将有助于揭示隔离综合征背后的适应性，这对于理解隔离对昆虫与植物协同进化的影响至关重要。
