Waste disposal and utilisation of its important components are pioneering goals for achieving sustainable development and a clean environment. Silkworm pupae (SWP) are considered a by-product of the sericulture industry and may contain a high concentration of selenium (Se) in some regions, making them a potentially hazardous waste posing health risks. This study examined six treatments of Se-rich SWP (0–100%) as a substrate for black soldier fly (BSF) larvae. Growth performance and protein content of BSF larvae were not affected by increasing SWP content. The total fat, mono-, and poly-unsaturated fatty acids in BSF pre-pupae increased with increasing SWP inclusion in the substrate, from P0 (pre-pupae fed control treatment) through P100 (pre-pupae fed 100% SWP treatment), by 18.83, 61.14, and 62.42%, respectively. The results of significance were: (1) BSF pre-pupae did not accumulate Se, maintaining the same amount of Se in their bodies (~0.18 mg/kg); (2) omega-3 fatty acids represented by linolenic acid in BSF increased by 1,223.35% from P0 to P100, with 70.65% recovered from the SWP; (3) valine percentage increased in BSF compared with the percentage of SWP by 25.30%; and (4) BSF larvae were observed reducing SWP waste by more than one-third. BSF larvae can reduce the waste from sericulture industry and exploit the beneficial properties and components of SWP, converting them into safe and highly nutritious products.

废物处理及其重要组成部分的利用是实现可持续发展和清洁环境的开拓性目标。蚕p（SWP）被认为是蚕桑业的副产品，在某些地区可能含有高浓度的硒（Se），使其成为潜在的危害健康的危险废物。这项研究检查了六种富硒SWP（0–100％）处理作为黑蝇（BSF）幼虫的基质。BSF幼虫的生长性能和蛋白质含量不受SWP含量增加的影响。从P0（以pre喂养前的对照处理）到P100（以100喂养前的100％SWP处理），BSF前-中的总脂肪，单不饱和脂肪酸和多不饱和脂肪酸随着底物中SWP含量的增加而增加，分别增长18.83％，61.14％和62.42％。有意义的结果是：（1）BSF-之前没有积聚硒，它们体内的硒含量相同（〜0.18 mg / kg）；（2）BSF中以亚麻酸为代表的omega-3脂肪酸从P0到P100增加了1,223.35％，从SWP中回收了70.65％；（3）BSF中缬氨酸的百分比较SWP的百分比增加25.30％；（4）观察到BSF幼虫可将SWP浪费减少三分之一以上。BSF幼虫可以减少养蚕业的浪费，并利用SWP的有益特性和成分，将其转化为安全且营养丰富的产品。（3）BSF中缬氨酸的百分比较SWP的百分比增加25.30％；（4）观察到BSF幼虫可将SWP浪费减少三分之一以上。BSF幼虫可以减少养蚕业的浪费，并利用SWP的有益特性和成分，将其转化为安全且营养丰富的产品。（3）BSF中缬氨酸的百分比较SWP的百分比增加25.30％；（4）观察到BSF幼虫可将SWP浪费减少三分之一以上。BSF幼虫可以减少养蚕业的浪费，并利用SWP的有益特性和成分，将其转化为安全且营养丰富的产品。
