The gut microbiota plays an essential role in its host’s nutrition, development and behavior. Although crickets are becoming major ecosystemic model systems have important societal applications, such as alternative animal proteins or biocatalysts, little is known about their microbiome acquisition how environmental factors shape this community. Therefore, study, we exposed sand field to soils with different characteristics microbial communities test the influence of these on community composition. We used 16S/18S rRNA gene Illumina sequencing analyze soil communities, targeting three domains life, Archaea, Bacteria, Eukaryotes. Our results showed a dominance Mucoromycota fungi Bacteroidota microbiota. were unable retrieve sufficient read numbers for Archaea. Most taxa that identified can degrade soil-derived complex organic matter, likely helping host digest food. had significant impact structure, supporting our assumption environment acquisition. Host sex also community, possibly because female guts bigger mass, leading differences oxygen concentrations.

The ever-growing human population has forced people to intensify agriculture meet the demand for food and feed. However, increase in global agricultural production also means an waste generation, which is mostly improperly managed, especially low- middle-income countries where adequate management infrastructure limited inefficient. Consequently, organic become a burden due its negative impact on environment health. In this sense, insect-based bioconversion could be economically viable, environmentally friendly, technically feasible approach management. Based review, wastes from agriculture, industry, household, municipalities, starch industry are considered as suitable substrates bioconverter insects. Commonly used insects include cricket, yellow mealworm, superworm, black soldier fly, house flesh fly blow fly. Rearing facilities must adapted provide optimal environmental conditions growth development of reared insect maximize rate efficiency. Bioconverter their by-products can industrially processed into animal feed, fertilizer biodiesel or extracted isolate bioactive compounds. challenges associated with social acceptance, method-, infrastructure- technology-related problems, availability substrates, political legal regulations. summary, potential reduce waste, create jobs, novel products, offer sustainable source protein feed world's growing population.

Abstract Background Innovations to establish agricultural value chains utilising side streams and their reintegration into the feed food supply are of great importance. Recyclates derived from biomass waste therefore becoming increasingly important as sources nutrients. The larvae black soldier fly (BSF; Hermetia illucens ) demonstrate considerable potential livestock due ability utilise a wide range organic substrates. In this study, BSF (BSFL) were reared on four different substrates: chicken diet (CD), high-fibre Gainesville (FD), or FD supplemented either with biochar (FD + BCH) single superphosphate SSP) recyclates sewage sludge processing.

The gut microbiota of black soldier fly larvae (BSFL, Hermetia illucens) play a crucial role in recycling various organic waste streams. This capability is linked to the presence potential common core BSFL. However, subjective thresholds for defining taxa and difficulty separating genetic environmental influences have prevented clear consensus literature. We analysed bacterial communities two genetically distinct BSF lines (wild type (WT) lab-adapted line (LD)) raised on ten different diets based agricultural by-products food Southeast Asia.

Abstract Background The black soldier fly (BSF, Hermetia illucens L.) is one of the most promising insects for bioconversion organic waste, which often carry a high microbial load with potential foodborne pathogens. Although horizontal transmission (from rearing substrate to larvae) has been extensively studied, less known about vertical microorganisms, and particularly pathogens, across different BSF life stages. Results This study investigated dynamics Escherichia coli stages (larvae, prepupae, pupae adults) cycle its associated (chicken feed) frass, based on combination general counts (based culture-dependent techniques) bacterial community composition 16S rRNA gene sequencing). Multiple interactions between microbiota substrate, frass larvae were affirmed. showed relative consistency among both composition. Diversification communities started during pupal stage, while notable changes compositions occurred metamorphosis adults. Furthermore, E. was after inoculation approximately 7.0 log cfu/g kanamycin-resistant , monitoring from larval adult stage. still contained substantial levels (> 4.5 cfu/g) taken up by larvae, limited observed decreasing trend until prepupal below detection limit (1.0 all samples end stage Additionally, did not have impact or Conclusions fluctuating underscored dynamic character throughout . Hence, these findings paved way future case studies pathogens consecutive other insect species.
