豆丹（即豆天蛾Clanis bilineata tsingtauica的幼虫）作为中国传统食用昆虫，因其高蛋白、低脂肪，养殖过程环境友好，绿色无公害等诸多优点，深受大众喜爱，具有显著的生态和经济价值及可持续开发潜力，已成为应对全球粮食短缺与推动生态农业转型的重要研究对象。近年来，豆丹作为食品和饲料的应用价值日益凸显。在农业领域，豆丹不仅是优质的蛋白补充来源，更凭借其高效的生物转化能力，在生态农业系统中扮演关键角色，促进农业废弃物的循环利用。本文系统综述了豆丹的生物学特性、人工养殖历程、资源化利用现状及面临的挑战，揭示了其从“农业害虫”到“多功能资源昆虫”的转变，旨在探索豆丹产业化发展与市场价值提升的中国可持续农业方案，助力国家“双碳”（碳达峰、碳中和）目标与乡村振兴。

 DanBean (i.e., larvae of Clanis bilineata tsingtauica), a traditional edible insect in China, has emerged as a significant research focus for addressing global food insecurity and facilitating ecological agricultural tranition. This prominence stems from its high protein, substantial ecological and economic value, and considerable sustainable development potential. Recent studies have increasingly revealed its utility in food and feed applications. Within agricultural systems, DanBean serves not only as a high-quality protein supplement but also functions as a vital biological resource due to its efficient bioconversion capacity, enabling the recycling of agricultural waste in ecological frameworks. This paper systematically reviewed the biological characteristics, artificial breeding, resource utilization, current agricultural applications, and persistent challenges associated with DanBean. Furthermore, it delineates the paradigm shift in public perception from “agricultural pest” to “multifunctional resource insect”. Ultimately, this work aims to propose a China-specific sustainable agricultural strategy for enhancing DanBean industrialization and market value, thereby supporting national “Dual Carbon” goals (i.e., Carbon Peak and Carbon Neutrality) and rural revitalization initiatives.
