A growing body of evidence has demonstrated the ability of insects to transform relatively low-value waste streams into valuable animal feed ingredients. The concept is simple: rather than recycling organic wastes into compost or methane, insect larvae consume organic waste and convert (or upcycle') organic waste into nutritious feed ingredients. The culture of insects raised specifically as feed for domestic animals/fish, has been evaluated for several decades. Insect larvae are typically rich in protein and can be an important source of lipids, depending on the species, rendering them excellent candidates for the bioconversion of waste materials. However, the widespread adoption and/or commercialization of such approaches has been limited, largely due to artisanal efforts, often in developing nations, with limited integration or coordinated development. Currently however, a convergence of factors has renewed interest in this area, including a number of large-scale commercial ventures around the world. A combination of new regulations in many municipalities restricting the disposal of organic wastes to landfills, together with the need to find sustainable ingredients for animal feeds has brought a renewed interest to re-evaluate the opportunities for insects to convert waste organics into valuable feed resources. The impact of larval feedstock characteristics (e.g. nutrient profile, chemical composition) to affect the subsequent feeding value of the larvae provides the opportunity to develop innovative products for the animal feed industry. For many decades, animal nutrition research has benefited greatly by the development and implementation of tools and standardized experimental approaches, which are required to systematically carry out nutrient requirement research, evaluate feed ingredients as potential candidates for dietary inclusion, develop adequate feed formulations to optimise animal production. The need for reliable tools and methodologies has led to the development of a number of experimental approaches to understand the degree by which nutrients are absorbed, either direct or indirect measurement of apparent nutrient digestibility as well as performance indices to gage animal performance. However, unlike other areas of animal nutrition, there exists no tools and standardized approaches to study nutritional dynamics of insect larvae. The application of parallel concepts for insect larvae will greatly advance fundamental and applied studies relating to nutritional dynamics across different species and life stages.

越来越多的证据表明昆虫有能力将相对低价值的废物流转化为有价值的动物饲料成分。这个概念很简单：昆虫幼虫不是将有机废物回收成堆肥或甲烷，而是消耗有机废物并将有机废物转化（或升级循环）为有营养的饲料成分。专门作为家畜/鱼类饲料饲养的昆虫养殖已进行了数十年的评估。昆虫幼虫通常富含蛋白质，并且可以是脂质的重要来源，具体取决于物种，这使得它们成为废物生物转化的绝佳候选者。然而，此类方法的广泛采用和/或商业化受到限制，这主要是由于通常在发展中国家的手工努力，整合或协调发展有限。然而，目前，多种因素重新引起了人们对该领域的兴趣，其中包括世界各地的一些大型商业企业。许多城市的新法规限制将有机废物处置到垃圾填埋场，再加上寻找动物饲料的可持续成分的需要，引起了重新评估昆虫将废弃有机物转化为有价值的饲料资源的机会的新兴趣。幼虫原料特性（例如营养成分、化学成分）对幼虫后续饲养价值的影响为动物饲料行业开发创新产品提供了机会。 几十年来，动物营养研究极大地受益于工具和标准化实验方法的开发和实施，这些工具和标准化实验方法是系统地进行营养需求研究、评估饲料成分作为膳食包容性的潜在候选者、开发适当的饲料配方以优化动物所必需的。生产。对可靠工具和方法的需求导致了许多实验方法的发展，以了解营养物质的吸收程度，直接或间接测量表观营养物质消化率以及衡量动物性能的性能指数。然而，与动物营养的其他领域不同，没有工具和标准化方法来研究昆虫幼虫的营养动态。昆虫幼虫的平行概念的应用将极大地推进与不同物种和生命阶段的营养动态相关的基础和应用研究。
