As the industrial insect production sector is rapidly growing, the high production cost of insects forms a constraint for the further growth of the insect industry. One of the main factors that greatly contributes to the total insect production cost and affects the profitability of insect farms is feed costs. Various agricultural by-products have been successfully evaluated and proposed as low-cost, alternative, insect feedstocks. In this context, this study evaluates a variety of Greek agricultural by-products as feeding substrates for Zophobas morio (F.) (Coleoptera: Tenebrionidae) larvae. More specifically, eleven agricultural by-products derived from the seed cleaning process of barley, oats, peas and vetch and the production of cotton, sugar beet and sunflower, were utilized singly and as components of compound isonitrogenous diets at two nitrogen levels (2.7% and 3.2% on dry matter basis). The results showed that larvae reared on sunflower meal, oat and barley (class II) by-products performed well in terms of larval growth and survival. In contrast, for most other diets tested high mortality rates were recorded, indicating the necessity for the formulation of diets that meet the nutritional requirements of the larvae. Our study highlights the potential of locally available by-products for the rearing of Z. morio larvae and contributes to determining their nutrient requirements.

Defatted larvae meal (dLM), specifically from black soldier flies, could help overcome the animal protein gap. As insect production is an emerging sector, current economic research is scarce and very diverse. Thus, the aim of this research was to develop a simulation model that enables the analysis of full industrial scale costs of producing dLM and to provide insight in the distribution of these costs in the insect supply chain. The deterministic supply chain model is built on three modules, technical, transition and economic module, which all follow a previously defined supply chain structure and allow to extract quantity and price information for intermediate or final products. The model was parameterized and checked for plausibility in multiple consultation rounds with the INSECTFEED consortium and business partners. Additionally, model behaviour was checked with scenario, sensitivity, and break-even price analyses. In the default situation 5.57 tDM raw substrate and 26.7 million neonates are required to produce 1 tDM dLM for a price of €5,116/tDM. Most costs are added in the raw substrate delivery (€1,952/tDM) and production and collection (€821/tDM) step. Important cost factors are the raw substrate (€1,939/tDM) and building and inventory (€1,459/tDM). Parameters with high relative response rate towards the price of dLM are the feed conversion rate, dry matter percentage of larvae, raw substrate price, larvae density, labour wage and growth rate. To reach break-even prices for substituting fish meal with alive grown larvae (AGL) (€1,318/tDM AGL), improving production parameters is not sufficient. Just changing prices of raw substrate to −€78/tDM or frass to €1,175/tDM would enable a profitable operation. However, these are not deemed as realistic in mass production. Although there is some insecurity in data, the model results are the most realistic representation of industrial scale production amounts and costs.

The increasing global population has led to high food demand and the interest for alternative resources is highly topical. The interest in utilizing insects as a source of food and feed has been rapidly increasing, as the on-growing population has made the need for protein even more demanding. Insect rearing is economically viable, since they can be fed with organic waste and agricultural by-products. The inclusion of bioactive compounds and active ingredients in insect diets has been identified as a potential key factor for enhancing their growth and performance. The aim of this study was to evaluate the effect of a diet enriched with functional ingredients of medicinal and aromatic plants and agricultural by-products of the Greek flora on the growth, survival and development of larvae of the yellow mealworm, Tenebrio molitor (Coleoptera: Tenebrionidae), in the context of larval density-induced stress. Wheat bran enriched with 5%, 10% or 20% of a prepared mixture containing post-distillation residues of medicinal and aromatic plants of the Greek flora (oregano, thyme, sage and rosemary, linseed oil, rock-samphire, industrial cannabis, and olive paste by-product) was evaluated as insect feeding substrate, whereas wheat bran alone (0% enrichment) served as control. Groups of 25, 50, 75 and 100 first instar larvae were separately collected, weighed, and put in cylindrical plastic cups to test if larval density had any effect on survival and development. According to our results, the final larval weight of T. molitor is significantly affected by the density of larvae but not by the rearing substrate. The highest individual weight among all tested substrates was achieved at the density of 25 larvae. Individual weights were highest when larvae were reared on 5% mixture. The weight of those reared on the control substrate was slightly lower, followed by the 10% and 20% mixtures. Larvae fed with 10% enriched substrate showed the highest survival rate, followed closely by those fed with the control and 5% substrates. Our results clearly demonstrate that larval survival is not density dependent, but density is important in the case of individual larval weight.

The consumption of edible Coleoptera, or beetles, is examined in this review as a viable remedy for the rising world food demand brought on by the population’s predicted expansion to over 9 billion by 2050. The review illustrates the nutritional profile of beetles, highlighting their high protein content, good fats, and oils, while being low in saturated fats and high in omega-3. Beetles have a rich history of consumption, with over 2 billion people, particularly in regions like Africa, Asia, and the Americas, incorporating them into their diets. They contribute significantly to human nutrition while also playing essential ecological roles, including soil fertilization and pollination. Beetles represent a promising solution to combat climate change, as traditional livestock production is a major greenhouse gas emitter, and beetle farming boasts lower emissions, reduced resource requirements, shorter life cycles, and superior feed conversion rates. Notwithstanding their advantages in terms of nutrition and the environment, there are obstacles including customer adoption, safety worries, and legal limitations. The review also covers how beetles are processed into different food items, such as liquids, pastes, and powders, and how these products are used in the feed, food, and nutraceutical industries. In general, edible beetles present a viable substitute food source with noteworthy nutritional and ecological benefits; yet, additional investigation and endeavors are required to surmount obstacles to their extensive integration.

Meeting food security is one of the major global challenges to ensure sufficient supply of food for current and future generations, considering increasing population growth and climate change issues. Consequently, the consumption of edible insects as an alternative food source has recently gained global attention for combating global food insecurity. The present review aims to provide information on the recent progress in consumption of edible black ant Smith, particularly Carebara vidua, as the main focus. The global consumption record of edible black ant Smith and consumer acceptance as well as the strategies used to increase consumer acceptance of eating edible black ant smith were proposed. In addition, the bioecology of black ant Smith was covered in this review. Further, details are provided in this review on the benefits to health, economy, and environment of practicing eating edible insects such as black ant Smith. Focus on the potential uses of Carebara vidua as a food ingredient in culinary cuisine and their safety concerns from rearing until processing were highlighted. The SCOPUS database was analysed using bibliometric software to understand the connections between recent scientific outputs and ant as human food thoroughly. BioRender software was used to create scientific figures. It is noteworthy to highlight that black ant smith contains high protein and micronutrient, especially iron and zinc are higher than that of plant-, animal-based food, and seafood that contribute significantly to meeting the daily protein and mineral intake amount for human. Moreover, the exhibition of antimicrobial and antioxidant properties of edible black ant smith suggests that it can be used as a future functional ingredients for food, pharmaceutical, and cosmetics purposes. Hence, edible black ant smith is promising as an alternative and potential source of food or medicine for sustainable food security.

Due to the increasing threat of climate change and the need for sustainable food sources, human consumption of edible insects or entomophagy has gained considerable attention globally. The larvae of Alphitobius diaperinus Panzer (Coleoptera: Tenebrionidae), also known as the lesser mealworm, have been identified as a promising candidate for mass-rearing as a food source based the on evaluation on several aspects such as the production process, the microbiological and chemical composition, and the potential allergenicity to humans. As a consequence, the European Commission has recently approved the utilization of lesser mealworms as human foods. Lesser mealworms are considered a good source of protein, with a protein content ranging from 50-65% of their dry weight and containing various essential amino acids. Lesser mealworms are also rich in other essential nutrients such as iron, calcium, and vitamins B12 and B6. Furthermore, the hydrolysates of lesser mealworms are known to contain antioxidants, suggesting the therapeutic properties of the insects. To enable and ensure a continuous supply of lesser mealworms, various rearing procedures of the insects and information on optimal environmental rearing conditions have been reported. However, like other edible insects, lesser mealworms are still not commonly consumed in Western countries because of various consumer- and product-related factors. Ultimately, the European Commission’s approval of lesser mealworms as a novel food is a key milestone in the development of the insect food industry. Embracing the consumption of edible insects can help address the challenges of feeding a growing population, mitigate the environmental impact of food production, and promote a more sustainable and resilient food system for the future.

The house cricket (Acheta domesticus) is considered one of the most promising farmed insect to be used as novel food, thanks to its attractive nutritional profile and its great taste. To the best of our knowledge, crickets in Europe are reared on soybean meal-rich feed which won’t be sustainable in the long run. Insect producers have shown interest in using more environmentally friendly substrates for cricket’s rearing. Among these, seaweed has been investigated as feed ingredients for insect rearing. However, no studies on crickets are available. We aimed to evaluate the potential use of the alga Palmaria palmata in the diet of house crickets (5%, 10% and 20% of the diet), in terms of insect performances and nutritional composition (protein, lipid, amino acids and fatty acids). Crickets fed seaweed-enriched diets showed good performance parameters (individual weight, cricket yield and survival) compared to crickets fed the control diet without presenting statistically significant differences (), while their nutritional composition changed significantly for some components. Protein content of the crickets increased when more seaweed was added to their diets (), while the fat content decreased (). Also, the amino acid composition of the crickets remained stable between dietary groups, except for histidine, methionine and lysine which increased in crickets fed more seaweed in the diet (, , , respectively). Finally, the presence of seaweed in the diet led to a transfer of the omega-3 eicosapentaenoic acid from the seaweed to the crickets (), which are naturally lacking this fatty acid. Based on this study, we conclude that the red alga Palmaria Palmata is a suitable substrate for cricket mass rearing up to 20 g/100 g of the diet. However, higher seaweed inclusion and longer dietary administration time could affect the nutritional composition of the house cricket differently, therefore they should be investigated.

The house cricket (Acheta domesticus) is considered one of the most promising farmed insect to be used as novel food, thanks to its attractive nutritional profile and its great taste.

Several alternative approaches have been proposed to address the need for sustainable protein sources within our existing food and feed systems. Insects are regarded as a promising alternative, which has led to increased attention from researchers worldwide. Acheta domesticus, the house cricket, is considered a potential insect species for industrial production and various applications due to its high nutritious value. Since it is expected that A. domesticus and its applications will continue to rise as an important field of study, the standardisation of production techniques are needed. Nowadays, variation in the measurement of parameters and differences in experimental design limit the comparison among studies and, therefore, the ability to build upon existing knowledge. By identifying gaps in current protocols and providing suggestions on rearing practices and reporting, this paper aims to take the first step towards standardisation of the production and characterisation of Acheta domesticus for research purposes. This initiative primarily focusses on research practices evaluating the impact of feed and environmental conditions on the performance of house crickets.
