Black soldier fly (BSF) larvae, Hermetia illucens L. (Diptera: Stratiomyidae), bio‐convert organic side streams into high‐quality biomass, the composition of which largely depends on the side stream used. In the present study, BSF larvae were reared on feed substrates composed of dried brewers’ spent grains, each supplemented with either water, waste brewer’s yeast, or a mixture of waste brewer’s yeast and cane molasses to obtain 12 different substrates: barley/water, barley/yeast, barley/yeast/molasses, malted barley/water, malted barley/yeast, malted barley/yeast/molasses, malted corn/water, malted corn/yeast, malted corn/yeast/molasses, sorghum‐barley/water, sorghum‐barley/yeast, and sorghum‐barley/yeast/molasses. The crude protein, fat, ash, and mineral contents of the BSF larvae fed each feed substrate were quantified by chemical analyses. The effect of substrate, supplementation, and their interaction on crude protein, fat, and ash contents of BSF larval body composition was significant. Calcium, phosphorus, and potassium were the most abundant macrominerals in the larvae and their concentrations differed significantly among substrates. These findings provide important information to support the use of BSF larval meal as potential new source of nutrient‐rich and sustainable animal feed ingredients to substitute expensive and scarce protein sources such as fishmeal and soya bean meal.

以农工业副产品为食的黑水虻幼虫的营养成分

黑水虻 (BSF) 幼虫 Hermetia illucens L.（双翅目：Stratiomyidae）将有机侧流生物转化为高质量的生物质，其组成在很大程度上取决于所使用的侧流。在本研究中，BSF 幼虫在由干啤酒糟粕组成的饲料基质上饲养，每一种都补充有水、废啤酒酵母或废啤酒酵母和甘蔗糖蜜的混合物，以获得 12 种不同的基质：大麦/水、大麦/酵母、大麦/酵母/糖蜜、发芽大麦/水、发芽大麦/酵母、发芽大麦/酵母/糖蜜、发芽玉米/水、发芽玉米/酵母、发芽玉米/酵母/糖蜜、高粱-大麦/水、高粱-大麦/酵母，和高粱-大麦/酵母/糖蜜。通过化学分析对喂食每种饲料基质的 BSF 幼虫的粗蛋白质、脂肪、灰分和矿物质含量进行量化。底物、添加物及其相互作用对 BSF 幼虫体成分的粗蛋白、脂肪和灰分含量的影响是显着的。钙、磷和钾是幼虫中最丰富的常量矿物质，它们的浓度在底物之间存在显着差异。这些发现为支持使用 BSF 幼虫粉作为营养丰富且可持续的动物饲料成分的潜在新来源提供重要信息，以替代昂贵且稀缺的蛋白质来源，如鱼粉和豆粉。
