The results showed that larvae from the BC group had the lowest body weight, body length, larval yield, substrate reduction rate and biological conversion efficiency. In terms of nutritional and functional indicators, larvae from the BC group had the lowest crude protein and ash content, but the highest crude fat content. KW group had the lowest content of alkaline-soluble proteins and water-soluble proteins. Meanwhile, the BC group had the highest water holding capacity while the KW group had the highest foaming stability. Furthermore, the BC group exhibited the strongest antioxidant activity for scavenging ABTS, DPPH, and hydroxyl radicals. In summary, a trade-off was observed: the KW group performed best in terms of larval production performance and nutritional enrichment while the BC group had a significant advantage in antioxidant properties.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":"12 6","pages":"985-996"},"PeriodicalIF":0.0,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147887026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with optimising insect rearing conditions and genetics, the insect microbiome is fundamental for the physiology, development, and adaptation of its host to various environmental conditions. To efficiently explore and exploit this ecosystem, a thorough understanding of its composition, function, and dynamics is required. This article aspires to provide a synopsis of the methodologies used to probe the insect-associated microbiome, primarily focusing on industrially relevant insect species. Key considerations for sample timing, selection, storage, and processing are discussed, emphasising the importance of standardised approaches to facilitate cross-study comparisons and enhance reproducibility. Marker gene and shotgun metagenomic sequencing are contrasted as means to investigate microbiome features, touching upon their respective (dis)advantages and potential use cases. Cultivation-based methods are essential for functional characterisation and translating the potential of insect-derived microorganisms for industrial applications. Direct isolation and enrichment cultures, along with anaerobic and aerobic cultivation techniques, are discussed as well. Methods to engineer microbiomes, such as axenic rearing and synthetic community assembly, have developed as powerful tools for exploring the role of specific microbes in host physiology. Beyond these approaches, metabolomics and metaproteomics are emerging as insightful techniques to dig deeper into microbiome functionality and host-microbe interactions. This article provides a multifaceted outline for researchers investigating the insect-associated microbiome and emphasises the importance of standardised methodologies and reporting for advancing the field.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":"11 18","pages":"361-395"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These concerns become even more significant when live insect larvae are used as animal feed. If not fully consumed by pigs, the larvae may remain on the farm, develop into adults, and thereby pose health risks. In order to implement effective biosecurity measures on farms, it is important to have a comprehensive understanding of how these insects contribute to pathogen transmission. This systematic review, conducted in accordance with PRISMA guidelines, seeks to evaluate the available evidence regarding the role of flies and beetles in transmitting pathogens to domestic pigs. A comprehensive search of PubMed®, Scopus, and Web of Science databases, focusing on peer-reviewed literature published between 2007 and 2023 in Europe and North America was conducted. The search identified 1,062 initial records, of which 39 articles met the inclusion criteria after screening and evaluation. Among the selected studies, 87% (34/39) focused exclusively on flies, 3% (1/39) focused on beetles, and 10% (4/39) included both. Flies were mainly identified as mechanical vectors for 26 pathogenic agents, including viruses, bacteria, and parasites while beetles were associated with the potential transmission of two viruses and one bacterium. Overall, only three studies provided evidence of pathogen transmission (African Swine Fever Virus, Porcine Reproductive and Respiratory Syndrome Virus, and Vesicular Stomatitis New Jersey Virus), which were based on experimental studies involving flies, and one study documented canthariasis caused by Tenebrio molitor larvae. In conclusion, this review identified a number of pathogenic agents that may be transmitted by insects to domestic pigs. The review also demonstrated a scarcity of studies that have convincingly proven the role of insects in pathogen transmission.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":"11 8","pages":"1339-1356"},"PeriodicalIF":0.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fermentation treatment of BSFL can retain more nutrients and reduce processing and transportation costs. This study investigated the effects of partially replacing fish meal with Black Soldier Fly Fermentation Homogenate (BSFFH) on the growth performance and health of Chinese soft-shelled ( Pelodiscus sinensis ) turtle. The experiment was divided into 4 different groups of juvenile P. sinensis diets. The control diet included 60% compound feed and 40% sea fish. The 34%, 61%, and 82% substitution groups were fed mixtures, and varying percentages of sea fish were replaced with BSFFH. The results indicate that replacing 34% and 61% sea fish with BSFFH significantly improved growth ( P < 0.05). The 61% substitution significantly decreased the muscle fiber size while the 82% substitution significantly upregulated the expression of myogenic genes MYF5 and MRF4 ( P < 0.05). Furthermore, replacing sea fish with BSFFH significantly increased hepatic TG content ( P < 0.05) and induced mild liver fibrosis, while it reduced the TG content in skeletal ( P < 0.05). However, BSFFH did not affect subcutaneous fat weight ( P > 0.05). Lastly, the 34% substitution significantly increased the intestine villus height and the ratio of villus height/crypt depth, while higher substitution reduced both values. In addition, the 61% substitution increased the mucus secreted by the intestine goblet cells. In conclusion, partially replacing sea fish with BSFFH improves the growth performance and intestine structure of Chinese soft-shelled turtles.

This paper explores the impact of larval density on the development of the lesser mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae). Seven different larval densities were examined in laboratory trials, ranging from 7.5 to 53 larvae per cm2, while the volumetric density per vial was consistent through the experiment at 10 larvae per cm3. The results showed a significant effect of larval density, restricted though to specific developmental traits of A. diaperinus larvae. Based on the results, the highest overall yield and biomass production was achieved at 53 larvae per cm2, however, this density resulted in prolonged development time and decreased larval growth and feed consumption metrics. It is suggested that a larval density of 30.3 larvae per cm2 could offer a favorable balance for achieving optimal biomass efficiency in terms of the time required for harvest, growth performance, feed utilization and economic feasibility. Nevertheless, to the best of our knowledge, this is the first work on the effect of larval density on the performance of A. diaperinus larvae and aims to contribute to the increase of the profitability of A. diaperinus mass-rearing production systems.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":" 15","pages":""},"PeriodicalIF":5.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Punica granatum (PL), Castanea sativa (CSL) and Robinia pseudoacacia fallen leaves (AL), and the leaves of two plants used in traditional medicine, Laurus nobilis (LL) and Mentha arvensis leaves (MAL), which are rich in polyphenols, flavonoids and proanthocyanidins were added to the TML standard diet as sources of antioxidant compounds. The fortified diets were administered to TML for their entire life cycle, and mean weight and survival rate analysed every 15 days, without observing a negative impact. After 45 days, when pupation exceeded 50%, the experiment was interrupted. TML accumulated antioxidant compounds from leaves, important to prevent inflammation and oxidative stress. Accordingly, we observed an increment of the antioxidant and radical scavenging activities respect to the TML fed with the standard diet (STDSL). Differently from STDSL, total fat content remained constant during development, while the quality of fat ameliorated, with a beneficial reduction of SFAs and an improvement of nutritional indexes associated with cardiovascular disease prevention. In addition, we observed an important reduction in n6/n3 ratio and the accumulation of linolenic acid.

The proteins isolated from the pupae were digested with pepsin or pancreatin, or pepsin + pancreatin and passed through a 30 kDa molecular cut-off membrane. The low molecular weight protein hydrolysates were characterised using RP-HPLC, HRMS, XRD, and FTIR-ATR. Hydrolysate from pepsin + pancreatin digestion showed significantly higher DPPH (77.13±2.57%), superoxide (72.08±1.15%) and hydroxyl (56.32±0.90%) radical scavenging activity in a cell-free system. Further, it reduced intercellular ROS production and suppressed the lipopolysaccharide-induced protein expression of TLR4, p-IKKβ, p-NF-, IL-1β, and COX2 in RAW 264.7 macrophages.

Larval stages of this species can be reared on several substrates, including grains and industrial by-products. However, this species may potentially accumulate contaminants from the substrate, including microplastics (MPs), which may represent a potential hazard for its utilization in food chain. Evidences for plastic degradation by mealworms have been reported, while there are few information about the retention of microplastics in the body and tissues of this species. The aim of the present study was to assess whether TM larvae reared on a MPs-contaminated substrate were able to retain MPs in body tissues and to evaluate the retention and excretion rate after fasting for 24 and 48 hours. For this purpose, fluorescent amino formaldehyde polymer microbeads (1-5 μm) were used to simulate a MPs contamination in the substrate used for larvae rearing. A relevant concentration of MPs were found in the gut and were associated with ingested feed. However, microscopic analyses indicated that the gut acts as a simple transit site and a barrier towards MPs migration in tissues. A marked reduction of MPS content was highlighted in larvae after fasting, even though a 48-hours fasting period was not sufficient to completely depurate insect gut from MPs. Results obtained in the present study suggest that the polymer microbeads used are recalcitrant to digestion by TM larvae, and show the relevant ability of depuration from MPs of this species. Taken together the results showed the suitability of TM to be reared on MPs contaminated substrates since larvae survival and growth resulted not hampered by the MPs presence and open cues on the fasting period able to completely depurate insect body from MPs residues.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":"75 9","pages":""},"PeriodicalIF":5.1,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138998815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yellow mealworm larvae are being developed for potential uses as human protein, pet, livestock and fish feed, reclamation of mycotoxin-contaminated grains, and more. Insect welfare is of great interest to consumers, producers, and academics; yet no studies have considered the species-specific welfare concerns of farmed yellow mealworms under current industry conditions. Following a model for considering farmed insect welfare, we review yellow mealworm biology and its relationships to welfare in commercial rearing facilities, including: interspecific interactions (predators, parasites, and pathogens), abiotic conditions (temperature, hydration, atmospheric gasses, lighting), nutrition (including pollutants, plastics, and hormones), intraspecific concerns (genetics, morphological defects, cannibalism, density, mating and oviposition needs, and handling-associated stress), and slaughter and depopulation methods (including anesthesia and stunning). From this review, we identify practical recommendations for improving current welfare concerns in the industry and mitigating future concerns that may appear as the industry continues to grow. Finally, we discuss future research directions that are necessary to better understand the welfare of this species.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":"50 12","pages":""},"PeriodicalIF":5.1,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138997380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
