Aphids pose a significant threat to global agricultural crop production, leading to widespread pesticide use and resistance. This necessitates the use of alternative substances, like plant secondary metabolites (PSMs). Plants have developed protective compounds known as alkaloids, terpenoids, phenolics, sulfur- and nitrogen-containing metabolites. These compounds exhibit promising characteristics against aphids, such as antifeedant, aphicidal, and disrupting survival fitness. This review highlights the importance and application of secondary metabolites in combating aphid populations. Different insect-resistant substances have different mechanisms for managing aphids and other pests, including defensive signaling, inhibiting growth, and attracting natural predators by releasing herbivore-induced volatiles (HIPV). The application of plant secondary metabolites as biopesticides has proven to be an effective, economical, and eco-friendly alternative to synthetic pesticide chemicals. Furthermore, this review comprehensively discusses the principle role of plant secondary metabolites, encouraging sustainable agricultural practices and emphasizing the integrated management of the aphid population.
蚜虫对全球农作物生产构成重大威胁，导致农药的广泛使用和抗药性。这就需要使用替代物质，如植物次生代谢产物（PSMs）。植物已经进化出了保护性化合物，如生物碱、萜类化合物、酚类化合物、含硫和含氮代谢产物。这些化合物对蚜虫表现出有前景的特性，如拒食、杀蚜和破坏生存适应性。本综述强调了次生代谢产物在对抗蚜虫种群中的重要性和应用。不同的抗虫物质对蚜虫和其他害虫有不同的防治机制，包括防御信号传导、抑制生长以及通过释放植食性昆虫诱导挥发物（HIPV）吸引天敌。植物次生代谢产物作为生物农药的应用已被证明是一种有效、经济且环保的合成农药替代品。此外，本综述全面讨论了植物次生代谢产物的主要作用，鼓励可持续农业实践，并强调蚜虫种群的综合管理。
