Given the current rate of human population growth, the mass breeding of insects for feed and food is in full industrial development, as a more efficient and effective alternative to conventional livestock for the production of animal protein. In these industries, the production of insect excreta (frass) represents one of the main outputs of the process, being up to 40 times greater than the production of animal biomass, which is why its use as organic fertilizer to replace the use of agrochemicals is considered a viable alternative in the development of sustainable agriculture and a circular economy. Through a review of all the existing literature, this article highlights the following benefits of the use of insect frass as organic fertilizer in sustainable agriculture: (1) contribution of nutrients to the soil, mainly nitrogen, easily assimilated by plant tissues; (2) addition of biomolecules and microorganisms that promote plant growth; and (3) increased tolerance to abiotic stresses and resistance to pathogens and pests due to the presence of different compounds and microorganisms. Therefore, insect frass from the mass breeding of insects for feed and food represents an important source of effective organic fertilizer for use in sustainable agriculture.

考虑到当前人口的增长速度，昆虫作为饲料和食物的大规模繁殖已在全面的工业发展中，作为生产动物蛋白的常规牲畜的更有效替代品。在这些行业中，昆虫排泄物（frass）的生产是该过程的主要输出之一，是动物生物质产量的40倍之多，这就是为什么将其用作有机肥料来代替农用化学品的原因。被认为是发展可持续农业和循环经济的可行选择。通过回顾所有现有文献，本文重点介绍了在可持续农业中使用昆虫标本作为有机肥料的以下好处：（1）营养成分对土壤的贡献，主要是氮，容易被植物组织吸收；（2）添加促进植物生长的生物分子和微生物；（3）由于存在不同的化合物和微生物，增加了对非生物胁迫的耐受性以及对病原体和害虫的抗性。因此，从昆虫的饲料和食物的大规模繁殖中获得的杀虫ass代表了用于可持续农业的有效有机肥料的重要来源。
