“…Reduced growth performance was observed when the broilers received the standard amino acid supplementation, but no change in performance parameters was observed when receiving supplemental amino acids, indicating that the birds were not receiving sufficient amino acids in a standard diet with BSFLM inclusion. Similarly, it was recently demonstrated that the addition of indispensable synthetic amino acids in BSFLM diet to equal levels of amino acids in soybean meal diet improved protein utilization efficiency in BSFLM ( Cheng et al, 2022 ). In the present study, the diets were analyzed, and the most notable effect on amino acid concentrations was the Arg deficiency.…”

“…Edible insect BSFL is a quality protein resource that can be used as a feed protein supplement for fisheries, poultry. It is of great significance for alleviating animal feed protein shortage ( Cardinaletti et al, 2022 ; Lu, S. et al, 2022 ; Cheng et al, 2023 ). The addition of microbes can improve the organic waste conversion efficiency of BSFL ( Zhang et al, 2021 ).…”

Black soldier fly larvae (BSFL) can convert a variety of organic wastes into biomass, and its gut microbiota are involved in this process. However, the role of gut microbes in the nutrient metabolism of BSFL is unclear. In this study, germ-free BSFL (GF) and gnotobiotic BSFL (GB) were evaluated in a high-protein artificial diet model. We used 16S rDNA sequencing, ITS1 sequencing, and network analysis to study gut microbiota in BSFL that degrade proteins. The protein reduction rate of the GB BSFL group was significantly higher (increased by 73.44%) than that of the GF BSFL group. The activity of gut proteinases, such as trypsin and peptidase, in the GB group was significantly higher than the GF group. The abundances of different gut microbes, including Pseudomonas spp., Orbus spp. and Campylobacter spp., were strongly correlated with amino acid metabolic pathways. Dysgonomonas spp. were strongly correlated with protein digestion and absorption. Issatchenkia spp. had a strong correlation with pepsin activity. Campylobacter spp., Pediococcus spp. and Lactobacillus spp. were strongly correlated with trypsin activity. Lactobacillus spp. and Bacillus spp. were strongly correlated with peptidase activity. Gut microbes such as Issatchenkia spp. may promote the gut proteolytic enzyme activity of BSFL and improve the degradation rate of proteins. BSFL protein digestion and absorption involves gut microbiota that have a variety of functions. In BSFL the core gut microbiota help complete protein degradation. These results demonstrate that core gut microbes in BSFL are important in protein degradation.

“…Hermetia illucens (Diptera: Stratiomyidae) is a saprophagous species widely used for the bioconversion of organic wastes [ 19 , 20 , 21 , 22 , 23 ]. Similar to other edible insects such as mealworms, silkworms, and crickets, H. illucens larvae can utilize carbon and nitrate sources in waste and produce high-quality protein, fatty acid, and mineral nutrients [ 24 , 25 , 26 ]. The fatty acids in H. illucens larvae are mainly saturated fatty acids (SFAs), which account for 50% of the total fat [ 27 , 28 ].…”

Acyl carrier protein (ACP) is an acyl carrier in fatty acid synthesis and is an important cofactor of fatty acid synthetase. Little is known about ACP in insects and how this protein may modulate the composition and storage of fatty acids. We used an RNAi-assisted strategy to study the potential function of ACP in Hermetia illucens (Diptera: Stratiomyidae). We identified a HiACP gene with a cDNA length of 501 bp and a classical conserved region of DSLD. This gene was highly expressed in the egg and late larval instars and was most abundant in the midgut and fat bodies of larvae. Injection of dsACP significantly inhibited the expression level of HiACP and further regulated the fatty acid synthesis in treated H. illucens larvae. The composition of saturated fatty acids was reduced, and the percentage of unsaturated fatty acids (UFAs) was increased. After interfering with HiACP, the cumulative mortality of H. illucens increased to 68.00% (p < 0.05). H. illucens growth was greatly influenced. The development duration increased to 5.5 days, the average final body weights of larvae and pupae were decreased by 44.85 mg and 14.59 mg, respectively, and the average body lengths of larvae and pupae were significantly shortened by 3.09 mm and 3.82 mm, respectively. The adult eclosion rate and the oviposition of adult females were also severely influenced. These results demonstrated that HiACP regulates fatty acid content and influences multiple biological processes of H. illucens.
