Hermetia illucens L. (the black soldier fly) has received increased attention because of its great potential in converting organic waste into a renewable resource. The prepupae have high proportions of proteins and fats and can serve as feedstuff for livestock and as feedstock for biodiesel production. With the goal to upgrade the conversion of low-value organic wastes into high-value proteins and fat on a large scale, the effects of the feedstuffs food waste, pig manure, chicken manure, and cow dung on the reproductive potential and nutrient composition of H. illucens were evaluated. The intrinsic rate of increase of H. illucens fed food waste (0.1249 d-1) was significantly greater than the rate of those fed pig manure (0.1167 d-1), chicken manure (0.1154 d-1), and cow dung (0.1049 d-1). The ash content of H. illucens fed food waste (30.8 g·kg-1 lyophilized prepupa matter (LPM)) was significantly lower than that of those fed chicken manure (37.6 g·kg-1 LPM) and cow dung (49.5 g·kg-1 LPM). The contents of crude fat, 372.4 g·kg-1 LPM, and protein, 436.9 g·kg-1 LPM, in prepupae fed food waste were the highest among the four treatments. The reproductive performance and prepupal nutrient composition indicated that food waste was the most suitable feed for H. illucens. The results from this study further demonstrate that the prepupae of H. illucens have great potential for use as a protein and fat source in animal feeds and as biodiesel material.
黑腹果蝇（Hermetia illucens L.）因其将有机废物转化为可再生资源的巨大潜力而受到越来越多的关注。预蛹富含蛋白质和脂肪，可作为家畜饲料和生物柴油生产的原料。为了提高低值有机废物向高值蛋白质和脂肪的大规模转化效率，评估了餐厨垃圾、猪粪、鸡粪和牛粪对黑腹果蝇繁殖潜力和营养成分的影响。以餐厨垃圾为食的黑腹果蝇的内禀增长率（0.1249 d-1）显著大于以猪粪（0.1167 d-1）、鸡粪（0.1154 d-1）和牛粪（0.1049 d-1）为食的黑腹果蝇。以餐厨垃圾为食的黑腹果蝇的灰分含量（30.8 g·kg-1 冻干预蛹物质（LPM））显著低于以鸡粪（37.6 g·kg-1 LPM）和牛粪（49.5 g·kg-1 LPM）为食的黑腹果蝇。以餐厨垃圾为食的预蛹中的粗脂肪含量（372.4 g·kg-1 LPM）和蛋白质含量（436.9 g·kg-1 LPM）最高。这四种处理方法中，以餐厨垃圾为食的黑腹果蝇的繁殖性能和预蛹营养成分最佳。研究结果进一步表明，黑腹果蝇的预蛹具有作为动物饲料蛋白质和脂肪来源以及生物柴油原料的巨大潜力。
