“…Certain heavy metals such as cadmium, accumulate in the pupae of black soldier fly, and zinc in the adults, making it possible to remove the heavy metals from the substrate (Bulak et al 2018;Gao et al 2017;Sverguzova et al 2021). Also, mercury accumulates in black soldier fly larvae and in this way treated compost was able to meet the EU threshold values of mercury (Attiogbe et al 2019). Black soldier fly larvae can also bio-recover nutrients from expired aquafeeds and re-introduce it in aquafeed formulations (Rodrigues et al 2022).…”

An overview is given on recent developments in insects as food and food by reviewing the literature which has appeared during the last few years on edible insects. An outlook to the future is provided. About a decade ago, the attention shifted from harvesting insects in the tropics to farming insects all over the world for food and feed applications. Most production is targeted towards pet food, but it will turn to aquafeed in the next two decades. More than 80% of all publications dealing with edible insects appeared during the last five years. Crickets and mealworms are used for human food while the black soldier fly is the main species used as animal feed. The criteria to choose insect species are automation, cheap substrates, disease avoidance, and market potential. Genetics are increasingly explored to improve production. The environmental impact of producing insects compares well to other alternative proteins, in particular their capacity to degrade organic waste streams. Edible insects are not only a good source of nutrients but also seem to provide health benefits not only for humans and animals, but also for plants (left over substrate). The challenge of convincing Western consumers is reviewed and whether sustainability is an issue. Processing techniques are being developed. The sector of insects as food and feed is developing fast thanks to an increasingly conducive legislative framework. It will progress further, provided that the insect industry, academia, governmental organizations, and public society closely cooperate.

“…The authors also concluded, the shorter half-lives of adults in Halogen light may be due to unsuitably higher temperature and excess heat generation. Attiogbe et al (2019) also applied the similar microclimatic conditions to achieve maximum mating, suitable oviposition and larval development in order to get higher efficiency towards mercury Sensitive to: Blue, Green and UV light (350 nm to 535 nm) Higher rates of larval production LED lights (14-24 Wm -2 ) Higher number of fertile eggs produced Increased adult survival contaminated waste wherein direct association between larval density and reduced mercury content from waste was observed.…”

Endeavours to recycle organic waste utilizing black soldier fly (BSF) Hermetia illucens (L.) into waste management and high nutrient biomass development have indeed picked up momentum recently. But there is not much data on their appropriate rearing conditions. Very few studies delineating the fecundity and reproduction capacities of BSFs concluded that the presence of natural sunlight or artificial light with intensity of 110-200 μ mol m2s-1 and above triggers mating and oviposition (about 85-90 %) at successfully higher rates along with ideal temperature (26 to 40 °C) and relative humidity (40-70 %) conditions. Optimum food moisture (50-80%) also plays a vital role in enhancing the consumption rate of waste and therefore the treatment efficiency of the larvae. Significant development of the BSF larvae and the treatment efficiencies were also observed to be governed by the pH of waste and the optimum range was defined to be of 6.0 to 9.0. The type of organic waste also equally influences the development, fecundity, and the lifespan of flies. The present review highlights the significant research that has been conducted with respect to lifecycle of BSFs, under the set of different light combinations (LED and fluorescent lights), temperatures and organic waste composites (protein rich and fat rich substrates). Conclusively, it was inferred that ameliorations in rearing conditions such as investigation of suitable light source, modifications in egg collection and hatching structures and knowledge of biology of flies can further boost the reproductive capability of fly thereby promoting successful insect rearing and mass production.

“…Following the ammonia, the presence of phosphorus sources in natural water bodies will as well hasten the Eutrophication menace. Thus, to sum up, the solid organic wastes entail an inclusive management for the sake of mitigating the environmental risks and reducing the long-term costs of disposal (Attiogbe et al, 2019).…”

The increase of annual organic wastes generated worldwide has become a major problem for many countries since the mismanagement could bring about negative effects on the environment besides, being costly for an innocuous disposal. Recently, insect larvae have been investigated to valorize organic wastes. This entomoremediation approach is rising from the ability of the insect larvae to convert organic wastes into its biomass via assimilation process as catapulted by the natural demand to complete its lifecycle. Among the insect species, black soldier fly or Hermetia illucens is widely researched since the larvae can grow in various environments while being saprophagous in nature. Even though black soldier fly larvae (BSFL) can ingest various decay materials, some organic wastes such as sewage sludge or lignocellulosic wastes such as waste coconut endosperm are destitute of decent nutrients that could retard the BSFL growth. Hence, blending with nutrient-rich low-cost substrates such as palm kernel expeller, soybean curd residue, etc. is employed to fortify the nutritional contents of larval feeding substrates prior to administering to the BSFL.Alternatively, microbial fermentation can be adopted to breakdown the lignocellulosic wastes, exuding essential nutrients for growing BSFL. Upon reaching maturity, the BSFL can be harvested to serve as the protein and lipid feedstock. The larval protein can be made into insect meal for farmed animals, whilst the lipid source could be extracted and transesterified into larval biodiesel to cushion the global energy demands. Henceforth, this review presents the influence of various organic wastes introduced to feed BSFL, targeting to reduce wastes and producing biochemicals from mature larvae through entomoremediation. Modification of recalcitrant organic wastes via fermentation processes is also unveiled to ameliorate the BSFL growth. Lastly, the sustainable applications of harvested BSFL biomass are as well covered together with the immediate shortcomings that entail further researches.
