The black soldier fly (BSF) has garnered the attention of the scientific community due to its outstanding efficiency in transforming organic waste into raw materials that can be incorporated into the value chain. A bibliometric and bibliographic review was conducted to elucidate the pivotal role played by the bioconversion of organic matter in shaping sustainable circular economy systems. The analysis revealed that black soldier fly larvae (BSFL) have proven effective in the bioconversion of common waste, such as household and livestock waste, yielding valuable biomass. Despite these advancements, the exploration of new sources of organic matter persists to mitigate its environmental impact. Emerging technologies enable the efficient processing of BSFL biomass, yielding substitutes for environmentally unfriendly materials. Although the literature emphasizes the advantages of BSF in constructing circular economy models, obstacles such as limited legislation and insufficient incentives for producers, concerns about pathogens and contaminants, and low public acceptance of this species are identified. However, the growing trend in scientific interest suggests that BSF could play a central role in building sustainable societies in the future. [ABSTRACT FROM AUTHOR]

One way to address food safety and feed production is through the rearing of insects that exhibit a small ecological footprint, high growth and reproduction rates, high levels of protein, fat and minerals. Forty growing guinea pigs were fed to evaluate the effects of isonitrogenated and isoenergetic diets in which different proportions of soybean meal (0%, 16%, 32% and 50%) were replaced with Hermetia illucens meal, evaluating feed consumption/day (g/day), total feed intake (g), final body weight (g), total weight gain (g) and feed conversion index. The trial was conducted in a repeated measures Analysis of Variance with Greennhouse-Geisser correction. Crude Protein in Hermetia illucens larva meal was 42.16 ± 3.67% (dry matter), replacing soybean meal did not show statistically significant difference between daily weight gain and body weight. The 32% replacement presented a higher daily consumption: 49.05 ± 0.69 g, total consumption: 1717 ± 24.32 g and food conversion: 3.22 ± 0.07. Incorporating Hermetia illucens larva meal at 16% of the protein requirement in Cavia porcellus feeding showed a feed intake per day of 34.57 ± 0.56 and better feed conversion, 2.50 ± 0.04. Hermetia illucens larval meal is an excellent high-quality protein substitute that satisfies the nutritional requirements with less feed in guinea pigs. These findings provide information on the potential of Hermetia illucens meal as a suitable alternative source of soybean meal for guinea pig feed. [ABSTRACT FROM AUTHOR]

The article titled "Nutritional composition of black soldier fly larvae (Hermetia illucens) cultivated in different substrates" presents a study on the nutritional composition of black soldier fly larvae cultivated in urban substrates. The objective of the study was to evaluate the nutritional composition of these larvae as an alternative for food security and increasing protein sources for animal feed. Different treatments were carried out using urban organic waste as a cultivation substrate. The expected results indicate that the nutritional value of Hermetia illucens larvae is similar to that of soybean meal, which demonstrates its potential as a substitute for conventional feed sources.
