Abstract Bioconversion by Hermetia illucens larvae is a novel technology for organic waste treatment and valorization. However, since the possible uses of products from this process are in agriculture and livestock, the bioconversion must guarantee the mineral quality of both the Hermetia illucens larvae frass and larval biomass. Therefore, this study aimed to assess the mineral content changes for both the larval biomass and larvae frass of Hermetia illucens after the manure bioconversion to determine their suitability as animal feed and organic fertilizer, respectively. Hermetia illucens larvae were put into a plastic box containing fresh cattle manure, and the control treatment with the same conditions without larvae was established. After the first pre-pupae were detected, frass and larvae were collected, and their mineral content was analyzed. At the end of the experiment, the larvae showed increases in some micro and macronutrients, especially calcium and manganese, increasing up to 2.6 and 22.6 times the initial concentration, respectively. The toxic elements concentration was increased in larval biomass, but these levels met the international legislation for animal feed. As a result, the mineral content in larval biomass revealed that Hermetia illucens could be potentially used as animal feed, which could be comparable with fish meal, and is probably better than soybean meal. However, the larvae frass could only be used as organic fertilizer in a Canadian context, with further treatment for decreasing the chromium content being necessary.

Hermetia Illucens Larvae

Food waste accounts for a substantial portion of the organic waste generated at an increasing rate worldwide. Organic waste, including food waste, is largely subjected to landfill disposal, incineration, and anaerobic digestion; however, more sustainable methods are needed for treating it. Treatment of organic waste using black soldier fly (Hermetia illucens) larvae is an environmentally safe and cost-efficient method that has been attracting increasing attention worldwide. Black soldier fly decomposes various types of organic waste and converts them into high-value biomasses such as oils and proteins. This review introduces the trends in research related to the treatment of organic waste by black soldier fly (Hermetia illucens) larvae (BSFL) and their bioconversion efficiencies in Asian countries. Perspectives on the growth of BSFL during waste treatment operation and optimal rearing conditions are provided. The trends in studies related to the application of BSFL as biofuel and animal feed are also discussed. Such use of BSFL would be beneficial in Asia, especially in countries where the technology for processing organic waste is not readily available. This review may provide further directions of investigations including culture techniques for industrial scale applications of BSFL in food waste treatment and resource production in Asian countries.

Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.

The experiment was carried out in agricultural land in Sorman between 4 - 2017 to 7 - 2017, in the design of Randomized Complete Block Design (RCBD) to study the response of vegetative traits and chemical properties in the tomato plant of Tariz for organic fertilization, by 6 treatments and 3 replicates, For SPSS statistical analysis at a significant level of LSD 0.05). The experiment included four types of semi-decomposed organic fertilizer (sheep manure, cattle manure, camel manure, horse manure) in 6 treatments, in addition to the control treatment, which included four treatments for each type of organic fertilizer as: fertilizer: soil by ratio (1: 3) that is 5Kg of fertilizer : 15 kg of soil, mixed treatment of fertilizer : soil (1: 1) (10 kg of fertilizer: 10 kg of soil), and double treatment (3: 1) (15 kg of fertilizer: 5 kg soil). The seedlings were planted in experimental units of 7.20 m2. The seedlings were treated in biological control using the garlic extract for insect protection after 15 days of planting, as well as the addition of simple proportions of hay as a cover to reduce the growth of herbs. The experiment showed that the treatment of cattle manure significantly increased most of the studied morphological traits (length of root, plant length, number of flowers, number of leafy branches), as well as significant increase in fresh and dry weight of leaves and average weight of five fruits.. There were significant differences in the content of the N, P in leaves and NPK elements in the fruits, while there was a significant increase in vitamin C content in fruits for all treatments.

Organic Waste Treatment

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Feather pecking is a key welfare challenge in laying hen husbandry. Feeding of live Hermetia illucens larvae could provide a possible solution to reduce feather pecking in hens. This research investigates effects of dispensing live H. illucens larvae to non-beak trimmed older laying hens on production performance, behavior and welfare. Control treatment hens were provided a commercial diet, while larvae treatment hens were provided live H. illucens larvae (using special dispenser) on top of a soy-free diet. Feather condition, production performance and egg quality were measured during the initiation (67 weeks age) and termination (78 weeks age) of the trial. Behavior of birds was monitored using video recording. Feed conversion ratio, body weight gain and egg laying parameters were similar for both treatments. At termination of the trial, larvae-fed hens exhibited better feather condition in comparison to control hens (p = 0.004). Behavioral observations indicated that larvae provision influenced the number of birds on floor during morning and afternoon hours. In conclusion, live H. illucens larvae could successfully replace soy in diets of older laying hens (in combination with local plant proteins). Provisioning of these insects also had a positive effect on the feather condition of laying hens with intact beaks.

Hermetia Illucens Larvae

Sustainable ingredients for animal feed are becoming scarcer. Insects have emerged as a promising protein and lipid ingredient for fish feed, and black soldier fly (BSF; Hermetia illucens) larvae in particular have great potential to efficiently convert organic matter into high value protein and fat. Seaweeds are a sustainable source of organic matter and complex carbohydrates, but can also provide marine long chain polyunsaturated fatty acids for fly larvae, and therefore could offer a commercially attractive alternative to traditional aquafeeds. However, pathogenic bacteria and faecal indicator organisms (FIOs) readily attach to seaweeds, therefore before this novel BSF larvae feed ingredient is advocated, microbiological risk assessments are warranted to ensure animal and public health protection from farm-to-fork. In this study, screening of raw materials and finished products during formulation of experimental insect meal fish feed was undertaken to evaluate the potential for the introduction of selected bacterial pathogens and FIOs via seaweed substrate to BSF larvae, and subsequent survival during multiple manufacturing processing stages. Processed seaweed powder was found to be a microbiologically safe feed substrate for BSF larvae. Low levels of FIOs were associated with larvae at the point of harvest, although larvae meal and extracted lipids were free of FIOs immediately after processing. During handling, distribution and storage the larvae meal and other externally sourced raw feed ingredients for larvae rearing and feed pellet formation became contaminated with FIOs and Listeria spp. FIOs were also present, albeit at very low levels, in the finished feed pellets. Processing treatments provided effective decontamination, and FIO and pathogen concentrations in finished products never exceeded microbiological quality standards for insect processed animal proteins. Microbiological contamination of raw materials and finished products during packaging and distribution, or originating from production environments, were identified as critical control points, requiring assessment to ensure good hygiene practices.

Disposal of organic waste in many countries is an acute problem; on the other hand, waste should be considered as an excellent raw material resource. Insect larvae can serve as one of the tools for the processing of organic matter. With their use, you can simultaneously solve several problems: reducing waste, obtaining animal feed, biologically active substances, valuable fertilizer, etc. The paper proposes the use of Hermetia illucens larvae, for the disposal of potatoes infected with plant nematodes. In this work, we evaluated the bioconversion of potatoes by the larvae of the fly H. illucens, and also analyzed the nematode composition of the obtained substrate from potatoes infected with Ditylenchus destructor and Rhabditis spp. during the life of the larvae. H. illucens larvae are able to effectively use fruit and vegetable wastes of com-mercial networks as feed substrate, including those infected with phytopathogenic or saprobiotic nematodes. Analysis of the degree of conversion of the substrate by the larvae of Black soldier fly showed that 70% of the waste was bioconverted. The formed zoo compost did not contain nematodes, in case of infection of the potato used for the experiment with phytoparasitic and saprobiotic nematodes. The ability of H. illucens larvae to eliminate potato and saprobiotic nematodes in the affected root crop has been shown, which makes it possible to recommend this method for utilization of potatoes spoiled during storage.
