摘要：

Plant–insectinteractions pose a major threat to global food security and ecologicalstability. This review provides a comprehensive synthesis of the molecular andphysiological mechanisms underlying plant immunity against herbivorous insects,with emphasis on structural defenses, secondary metabolites, and hormonesignaling pathways including Jasmonic acid, salicylic acid, and ethylene. Ithighlights key advances in understanding defense signaling crosstalk,effector-triggered responses, and the role of microbiota and environmentalcues. The review further discusses insect counterstrategies and explorescutting-edge technologies-CRISPR/Cas9, RNA interference, and metabolicengineering that are reshaping pest management. However, challenges remain,including limited field validation of engineered traits, ecological trade-offs,and regulatory hurdles. We conclude by outlining future research directionsfocused on multi-omics integration, climate-resilient defense networks, andethical deployment of plant biotechnologies within sustainable agroecosystems.
