| 【目的】本文旨在研究不同淀粉源饲料对黑水虻Hermetia illucens生长性能、营养组成及繁殖性能的影响。【方法】将5种不同来源的淀粉（玉米、小麦、木薯、高粱、扁豆）、麦麸、棉籽粕按5﹕2﹕3的比例混合制成黑水虻饲料。选取5日龄黑水虻幼虫置于保鲜盒中进行饲养，评估黑水虻的生长性能、营养成分、繁殖性能、几丁质含量。【结果】不同淀粉源饲料对黑水虻幼虫存活率无显著影响（P > 0.05），采食小麦淀粉饲料和高粱淀粉饲料黑水虻的饲料系数较低（P < 0.05），而采食高粱淀粉饲料黑水虻的羽化率较高（P < 0.05），扁豆淀粉饲料黑水虻的每克卵粒数最高（P < 0.05）。采食高粱淀粉饲料黑水虻幼虫的粗蛋白质、总氨基酸、必需氨基酸、非必需氨基酸含量较高（P < 0.05），采食小麦淀粉饲料黑水虻幼虫的粗脂肪含量、饱和脂肪酸含量较高（P < 0.05），高粱淀粉饲料黑水虻幼虫的单不饱和脂肪酸、多不饱和脂肪酸含量较高（P < 0.05）。不同淀粉源饲料对黑水虻蛹壳的几丁质含量无显著影响（P > 0.05），但玉米淀粉组黑水虻成虫的几丁质含量最高（P < 0.05）。【结论】以生长和繁殖性能及营养指标综合评价，小麦淀粉和高粱淀粉可能是黑水虻饲料适宜的淀粉源。 |

| 【Aim】This study aimed to investigate the effects of feeds with different starch sources on the growth performance, nutritional composition, and reproductive performance of Hermetia illucens.【Methods】Five starch sources (corn, wheat, cassava, sorghum, lentil) were mixed with wheat bran and cottonseed meal at a ratio of 5:2:3 to formulate feeds for H. illucens. Five-day-old H. illucens larvae were selected and reared in fresh-keeping boxes to evaluate their growth performance, nutritional components, reproductive performance, and chitin contents.【Results】Results showed that different starch-based feeds had no significant effect on the survival rate of H. illucens larvae (P > 0.05). Larvae fed on wheat starch- or sorghum starch-based feeds exhibited a lower feed conversion ratio (P < 0.05), while those reared on sorghum starch-based feed had a higher eclosion rate (P < 0.05). Notably, the group fed with lentil starch-based feed produced the highest egg count per gram (P < 0.05). Larvae fed with sorghum starch-based feed had significantly higher contents of crude protein, total amino acids, essential amino acids, and non-essential amino acids (P < 0.05). In contrast, those reared on wheat starch-based feed showed elevated levels of crude fat and saturated fatty acids (P < 0.05). Additionally, larvae in the sorghum starch group exhibited higher concentrations of monounsaturated and polyunsaturated fatty acids (P < 0.05). Different starch-based feeds had no significant effect on the chitin content in the pupal exuviae of H. illucens (P > 0.05). However, adult H. illucens from the corn starch group had the highest chitin content (P < 0.05).【Conclusion】Based on a comprehensive evaluation of growth performance, reproductive traits, and nutritional indices, wheat starch and sorghum starch may represent optimal starch sources for H. illucens. |
