Abstract: The black soldier fly larvae(BSFL)(Hermetia illucen),as an emerging resource-based insect, efficiently converts organic waste into organic matter such as protein and fat. To investigate the effects of different feeding substrates on nutritional composition changes in Hermetia illucens larvae, this study employed meta-analysis to synthesize domestic and international literature data on feeding black soldier flies with diverse substrates(including food waste, livestock manure, animal feed, fruit and vegetable waste, and other categories). The analysis investigated variations in key nutritional components within the insects, such as crude protein, crude fat, and ash content. Results indicate significant differences(P<0.05)in nutritional content among BSFL reared on different substrates. Those fed animal feed exhibited the highest crude protein content, while those fed food waste and fruit/vegetable waste showed significantly higher crude fat content(P<0.05)compared to the other three groups. The poultry manure group exhibited the highest ash content. Overall, the nutritional content within BSFL is closely related to their feeding substrate. Different materials such as poultry manure, fruit and vegetable waste, and food waste exhibit distinct differences in composition and characteristics. These variations may influence the nutrient uptake and conversion processes in BSFL.
