Black soldier fly larvae (BSFL) can also bioaccumulate micronutrients from various substrates. The purpose of this study was to assess whether BSFL can bioaccumulate significant concentrations of bioavailable α and ɣ-tocopherol (TOC) from vitamin E (VE) rich substrates. BSFL were reared on VE rich substrates, e.g. wheat germ oil, bran, etc. α and γ-tocopherol were quantified in larvae and substrates by HPLC. VE bioaccessibility was estimated using an in vitro model of digestion. Uptake efficiency of micellarized VE by intestinal cell was estimated using Caco-2 cells. BSFL were at least as rich in α-TOC, but not ɣ-TOC, as their rearing substrates. VE bioaccessibility was almost always significantly lower in BSFL than in corresponding substrates. Conversely, VE uptake efficiency was either not significantly different or significantly higher in BSFLs than in substrates. Thus, VE enrichment of BSFL from VE rich substrates, in particular co-products such as brans and oil cakes, could be an innovative way to recycle VE and to provide significant amounts of sustainable VE in farm animal feed.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139276742","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}

Its rearing is done in two steps, the ‘nursery diet’, and the ‘rearing’ diet, but the nursery diet may increase costs and labour. The effect of the nursery diet time on larval performance, substrate reduction, and larval nutritional composition were evaluated to determine whether it is possible to remove this step from the BSF production process. Chicken feed was used as nursery diet and restaurant food waste for the rearing diet. The performance and chemical composition of BSF larvae with eggs inoculated directly into the restaurant food waste and incubated in the nursery diet were evaluated for six, eight, ten, and 12 days. Substrate reduction was higher for larvae raised without nursery diet. The final weight, growth rate, and number of live larvae were the same for larvae reared with or without nursery diet. Larvae reared without nursery diet had higher crude protein, lower dry matter, and ash content than larvae on nursery diet. The nursery diet did not improve most of the characteristics analysed, and the nutritional levels of the larvae. This may suggest that this step could be ignored when rearing BSF larvae on restaurant waste.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139277304","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}

However, before BSFL may legally be reared on such materials, and subsequently fed to livestock animals, safety must be guaranteed. Many hazards could be relevant, depending on the origin of the waste stream. Small- and large-scale experiments were performed in which BSFL were reared on the organic wet fraction of municipal household waste (OWF), kitchen/fast food waste (FFW), mushroom feet stems (MF), pig manure liquid slurry mixed with roadside silage grass (PMLSG), pig manure solids (PMS), and secondary sludge from slaughter waste (SW). Larval yields were highest on the control (chicken feed + water) and the FFW. Substrates and larvae were analysed to determine the presence of heavy metals, acrylamide, pesticides, veterinary drugs, and pathogenic bacteria. Cadmium (Cd) bioaccumulated in larvae reared on all substrates, in line with previous research. Some pesticides and veterinary drugs were found in the substrates: concentrations in the larvae were low, but potential formation of metabolites could be studied further. Acrylamide was present in the FFW, but not in the larvae reared on it: more research is needed to determine the (metabolic) fate. Bacillus cereus and traces of Salmonella spp. were found on some larval samples, but appropriate processing is anticipated to minimize potential risks. Based on these results, we conclude that most tested substrates are suitable for rearing BSFL, and do not appear to present major safety concerns, aside from the need for monitoring Cd concentrations in the substrates, and control measures for pathogenic bacteria. Further verification to account for variance in contamination of substrates is needed for definitive conclusions on the safety.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139279076","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}

As a result of fermenting WB50-FW50 using microorganisms (Limosilactobacillus fermentum, Lactobacillus acidophilus, and Pediococcus acidilactici) with excellent enzymatic activities to increase the absorption rate in the body, WGR was increased by 40% compared to non-fermented WB50-FW50. To increase the value of the product and the convenience of distribution and use, we attempted to manufacture a pellet-type feed with a diameter of 6 mm and length of 10 mm. Based on the selection of inexpensive raw materials without adversely affecting viability and WGR, 0.05% sorbic acid was added as a preservative, and 20% agar was added as an excipient. The drying time after pellet moulding was determined to be 50 min, considering the high WGR, and the final pellet-type fermented mixed feed with sorbic acid and agar (PFMF) preparation was completed. Finally, compared to powdered wheat bran, a conventional mealworm feed, PFMF fed to mealworms increased WGR by 25.6% and body fat content by 18.8%. In conclusion, we suggest that the PFMF is a valuable feed with high economic feasibility, eco-friendliness, and convenience for breeding of mealworms for biodiesel production.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139282357","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}

Over the last few decades, managed honey bees have faced large-scale losses worldwide. Various causes include the spread of pathogens and parasites, habitat loss and loss of forage, pesticide use, and climate change. Many scientists investigated these issues worldwide separately and independently, often using different methodologies, and this approach might lead to conflicting and sometimes erroneous findings. To provide global and sustainable solutions, a group of bee scientists established COLOSS, a non-profit association for the prevention of honey bee COlony LOSSes. Its mission is to investigate the causes of declining bee health and find effective means to improve the well-being of bees. COLOSS comprises various Core Projects and Task Forces focusing on specific topics identified by the association to receive priority attention. Among the core projects, the COLOSS BEEBOOK is a unique venture aiming to provide a standardised methods manual for studying the honey bee. The project’s goal has been to create a comprehensive collection of established methods and techniques for honey bee research, with the aim of making studies conducted by different groups across the world more comparable. The resulting practical manual contains over 2,000 standardized methods across all fields of honey bee research. It is definitive, but evolving, research manual. There is a strong need for standardisation in the fast-growing field of edible insect farming and research. The COLOSS BEEBOOK stands as a testament to the achievements that can be made when researchers collaborate towards a common goal, and it can serve as an inspiration for the establishment of standardized methods for the mass rearing of edible insects.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139281801","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}

Four isonitrogenous and isolipidic diets (30% crude protein) were formulated to replace 0% (T0), 40% (T40), 80% (T80) and 100% (T100) of crude protein from SBM with BSFLM. Fingerlings (initial weight = 18.00 ± 1.25 g, n = 135) were stocked in aquaria. At end of the growth experiment, fifteen fish from each group were exposed to bacterial (Staphylococcus aureus) challenge (0.80 CFU/ml) for fifteen days. Fish in BSFLM substituted groups showed significantly higher growth and condition as compared to those in T0. Inclusion of BSFLM did not affect the chemical composition, profile of amino acids, and fatty acids in fish. However, the levels of lauric acid, linoleic acid, α-linolenic acid, decosahexanoic acid, and eicosapentanoic acid increased in BSFLM fed fish. The concentration of catalase, superoxide dismutase and lysozyme increased with addition of BSFLM in diet at end of the growth experiment. These oxidative stress biomarkers indicate that replacement of SBM with BSFLM up to 80% improved the growth and disease resistance in basa against gram-positive bacteria. BSFLM can be a future alternative protein source for commercial production of aquafeed for this species.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139282292","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}

That being the case, a means to tackle this growing demand for insects is to invest in breeding strategies aiming for the production of hybrids with improved economically and biologically valuable traits. In this framework, the objective of the present study was to evaluate the mating compatibility among four strains of the yellow mealworm, Tenebrio molitor, from different geographical areas (Greece, Belgium, Italy and USA) and to assess and compare the performance of the produced inbred and partially outbred lines. All trials were performed in crates of the size (40 × 60 cm) typically used in industrial rearing of mealworm. Adults of T. molitor were placed in the crates and were left to mate and oviposit. To assess mating compatibility, the amount of oviposited eggs (g) as well as the larval hatching rate were recorded. For the assessment of larval performance of inbred and partially outbred lines, two to three weeks old larvae were placed in crates together with Insectus as feeding substrate. The results showed that all crossed lines demonstrated compatibility, and certain combinations outperformed others as suggested by the high cumulative number of eggs and the larval hatch rates for both inbred and partially outbred lines produced. For hatched larvae, there were significant differences among the inbred and partially outbred lines. The highest hatch rates recorded for the Italian-Italian, Belgian-Italian, and Belgian-USA lines. Concerning offspring performance, all crosses followed a similar pattern in terms of final larval weight.

This study selected indigenous locust species with a high reproductive and rapid growth rate to determine the most favourable feeding plant species for locust mass-rearing. A suite of seven locust species, Acanthacris ruficornis (Fabricius, 1787), Cantantops melanostictus (Schaum, 1870) Locusta migratoria (Linnaeus, 1758), Petamella prosternalis (Karny, 1907), Chortoicetes terminifera (Walker, 1870), Cataloipus zulvensis (Sjöstedt, 1929) and Ornithacris cyanea (Uvarov, 1924) (Orthoptera: Acrididae) were collected from tribal orchards in Lufule, Tshikweta and Belleview villages in Limpopo province, South Africa and reared on the crop feeding plant species. The feeding, reproductive output (nymph production), adult longevity, and mortality of the suite of the locust species were determined on Zea mays L. (Poaceae), Phaseolus vulgaris L. (Fabaceae) and Panicum maximum jacq. (Poaceae) under the control, choice-one, choice-two, and choice-three tests. Choice-one and -two tests had three and two feeding plants, respectively. Whilst both the control and choice-three tests had a single-feeding plant species. I found that locust feeding, reproductive output, adult longevity, and mortality depended on the plant species, and this was more significant for the control, and choice-one compared to the choice-two and choice-three tests. Both the nymphs and adults of the locusts fed significantly more on P. vulgaris and Z. mays, respectively. Locust colonies exposed to P. maximum in the choice-three test reproduced and survived lesser significantly than all the tests. Results suggest that the combination of P. vulgaris and Z. mays or P. vulgaris alone can be used to mass-rear the suite of the locust species, particularly C. melanostictus, A. ruficornis and C. terminifera.

In conventional rearing practices, the demand for a consistent supply of fresh leaves, particularly from the primary food plant, Ricinus communis (castor), poses significant challenges due to leaf quality variations and scarcity. This predicament sometimes renders the rearing process uncertain and time-consuming. The review emphasizes the pivotal role of artificial diets, particularly those comprising Ricinus communis (castor), soybean, agar agar, preservatives, gelling agents, carbohydrates, sterols, inositol, salt mixtures, citric acid, ascorbic acid, and water, in addressing these challenges. These carefully formulated diets have demonstrated their ability to provide a stable and uniform source of nutrition, significantly impacting key parameters such as hatchability, larval and pupal durations, and shell ratio in comparison to traditional leaf-based diets. Furthermore, the study highlights the potentiality of various artificial diet compositions that can serve as viable alternatives for Samia ricini rearers. By embracing these innovative nutritional approaches, rearers can not only enhance their livelihoods but also contribute to increased silk production. Through an extensive analysis of experiments and studies, this review underscores the importance of thoughtful diet selection in achieving successful rearing of Samia ricini, paving the way for sustainable and efficient sericulture practices.","PeriodicalId":48604,"journal":{"name":"Journal of Insects as Food and Feed","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139290863","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}
