Diet Formulation

The black soldier fly (BSF; Hermetia illucens L.) is a very promising insect species due to the ability to convert low-value substrates in highly nutrient feed. This work aimed to study the effect of three nominally isoenergetic diets containing plant ingredients such as barley, alfalfa, and wheat byproducts, formulated to be higher in nonfiber carbohydrates (TMD1), fibers (TMD2), and protein (TMD3) in comparison to an extensively genetic modified cereal (cornmeal)-based diet (C), on the growth, yield, and nutritive traits of BSF prepupae (BSFPs). Three growing trials with four biological replicates were carried out. Proximate and fatty acid analyses were performed on the diets and BSFPs. Feed conversion ratios (FCR), dry matter and nutrient yields, and apparent concentration factors (aBCF) for fatty acids (FAs) were calculated. Diet formulation had a substantial effect on the survival, development rate, and larval yield, but the FCR was unaffected. The BSFPs fed TMD3 did not result in a higher crude protein content in comparison to the C or TMD2 diets. Despite the leveled fat content of the diets, BSFPs reared on TMD1 were highest in fat, saturated FA, and fat yield. An apparent bioconcentration factor (aBCF) value lower than unity that was found for the unsaturated FA suggests that the BSFPs inefficiently absorb them from the diet or possibly turn them into saturated FA. However, the unsaturated FA accumulation in BSFPs depended on the levels that were found in the diet, which suggested some possibilities for the FA profile modulation. Overall, the TMD2 performed well despite the low-value of its main ingredients and high fiber content and can be considered to be a feasible option for the mass rearing of BSFPs that are intended for animal feed.

Amino Acid Requirements

<p class="awabstrak2">Increasing demand of protein source for animal feed, particularly fish meal and soybean meal has led to a problem in the future. It is a need to look for an alternative protein source, in order to meet amino acid requirements maintaining livestock production level. Insects possesing high quality, efficient dan rich protein content at all life stages such as Black Soldier Fly (BSF, <em>Hermetia illucens</em>) could be used as one of the alternatives. The flies grow and reproduce easily, have high feed efficiency and can be reared on bio-waste streams. These are neither pests nor vectors of diseases. Insect meal generally possesses levels of chemical contaminants which are below recommended maximum concentrations. The larvae have antibacterial (<em>Escherichia coli</em> O15:H7, <em>Salmonella enterica</em> serovar <em>Enteritidis</em>) and antiviral (enterovirus and adenovirus ) properties. Larvae of BSF could be scaled up easily and possess 40-50% protein content, including some essential amino acids that can be used to replace both fish meal and soybean meal in feed.</p>

Important Species

Abstract Hermetia illucens L. (Diptera: Stratiomyidae), the Black Soldier Fly (BSF) is an increasingly important species for bioconversion of organic material into animal feed. We generated a high-quality chromosome-scale genome assembly of the BSF using Pacific Bioscience, 10X Genomics linked read and high-throughput chromosome conformation capture sequencing technology. Scaffolding the final assembly with Hi-C data produced a highly contiguous 1.01 Gb genome with 99.75% of scaffolds assembled into pseudochromosomes representing seven chromosomes with 16.01 Mb contig and 180.46 Mb scaffold N50 values. The highly complete genome obtained a BUSCO completeness of 98.6%. We masked 67.32% of the genome as repetitive sequences and annotated a total of 16,478 protein-coding genes using the BRAKER2 pipeline. We analysed an established lab population to investigate the genomic variation and architecture of the BSF revealing six autosomes and an X chromosome. Additionally, we estimated the inbreeding coefficient (1.9%) of a lab population by assessing runs of homozygosity. This provided evidence for inbreeding events including long runs of homozygosity on chromosome five. Release of this novel chromosome-scale BSF genome assembly will provide an improved resource for further genomic studies, functional characterisation of genes of interest and genetic modification of this economically important species.

The Impact

Population growth and rapid urbanisation have increased the global demand for animal feed and protein sources. Therefore, traditional animal feed production should be increased through the use of alternative nutrient sources. Insects as feed are beginning to fill this need. One such insect is the black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae). However, to more effectively mass produce the black soldier fly, a better understanding of its thermal biology is needed. Thus, the aim of this study was to evaluate the impact of age, size, and sex on adult black soldier fly thermal preference. The thermal preference of adult black soldier flies was determined by exposing flies to a thermal gradient with a range of surface temperatures and monitoring their positions over time. An aluminium plate was used to create a linear thermal gradient where surface temperatures ranged from ~15-60 °C. Flies were distinguished by age (1-d-post-emergence vs 7-d-post-emergence), size (large vs small) and sex (male vs female) to assess whether thermal preference differed by specific life-history traits. Thermal preference for 7-d-post-emergence adults was significantly lower (19.2 °C) than 1-d-post-emergence adults (28.7 °C), respectively. Similarly, small adults selected significantly cooler (21.1 °C) temperatures than large adults (26.9 °C). No significant differences in thermal preferences were found between sex, regardless of age or size. In fact, males and females had similar thermal preference of 23.8 and 24.2 °C, respectively. This study reveals that multiple life-history traits of adult black soldier fly affect their thermal preference, and thus should be taken into consideration by mass rearing facilities to optimize production.

By Products

The oilseed crops Crambe abyssinica and Camelina sativa produce oils rich in erucic acid and n-3 polyunsaturated fatty acids (PUFA), respectively. After pressing the oil, a seed cake remains as a protein-rich by-product. Edible insects may convert this seed press cake and the defatted seed meal produced from it into insect biomass suitable for animal feed. Black soldier fly larvae (BSF, Hermetia illucens) can grow on a wide range of organic waste types, but may be hindered by excess protein or the plant toxins characteristic for these two oilseed crops, i.e. glucosinolates and their breakdown products. We tested the effects of 25, 50 and 100% oilseed by-product inclusion in the diet on survival, development, biomass production and fatty acid composition of BSF larvae. Larval performance on diets with up to 50% camelina by-product or 25% crambe by-product was similar to performance on control diet (chicken feed), and decreased with higher inclusion percentages. Larval fatty acid profiles differed significantly among diets, with larvae fed press cake more distinct from control than larvae fed seed meal. Larvae fed camelina press cake had more α-linolenic acid, whereas larvae fed crambe contained most oleic acid. The n-6:n-3 PUFA ratio decreased with increasing proportion of by-product, especially on camelina diets. Lauric acid content was highest in larvae fed 100% camelina meal or 50% crambe meal. These results indicate that BSF larvae can be successfully grown on diets with camelina or crambe oilseed by-products, and that the resulting larval n-6:n-3 PUFA ratio is favourable for animal feed. However, the fate of glucosinolates and their derivatives remains to be determined, to guarantee chemical safety of camelina- or crambe-fed BSF larvae for animal feed.

Organic Resources

Using larvae of the black soldier fly (Hermetia illucens; BSF) to convert low-value residual organic resources into high-value products like protein-rich animal feed ingredients and biofuel while managing organic waste has developed into a global industry. Considering the associated exponential increase in publications dealing with diet conversion efficiency by BSF larvae, it is timely to suggest procedures to arrive at an improved harmonization and reproducibility among studies. This means establishing protocols for describing the basic experiment design, fly colony origin, rearing procedures, reference and experimental feeding substrates, and sampling preparations including microbiota and chemical analyses. Such standardised protocols are instrumental to allow conversion efficiencies to be calculated. Some of these parameters are relatively easy to describe such as giving the origin and rearing conditions, while others are more challenging (e.g. description of microbe community). In this article we discuss and propose such procedures with the aim to arrive at standardisation of how future resource conversion studies with BSF larvae are conducted and how results are communicated.

Insects As Food

Insects are a promising alternative protein source and their possible integration in the human diet has been extensively studied, also with reference to the degree of consumer acceptability and the main factors determining reluctance among Western consumers. Several studies have also proposed the use of protein meals derived from insects in animal feed as a possible way to promote the development of the insect chain. Consumer attitudes, perceived risks, and intention to eat insect-based foods have been extensively researched, yet the relationships between those factors are still unclear. On a sample of 202 Italian consumers, the present research used the Entomophagy Attitude Questionnaire (EAQ) to analyse the degree of acceptability of insects as food and meat obtained from animals raised on insect-based feeds with a specific focus on the role of attitudes and perceived risk. The research also evaluated the differences in acceptability between different types of animals fed with insects. The results show that the intention to engage in entomophagy is significantly correlated with all three of the EAQ’s subscales, as well as with perceived risk. However, the effect of perceived risk does not significantly improve the predictive validity of EAQ with respect to the intention to eat insect-based food. The results also show that the degree of acceptability for different insect meal-reared animals changes among consumers: beef and pork are characterized by a lower degree of acceptability, while poultry and fish are more accepted by consumers.

First Time

Hermetia illucens (Linnaeus, 1758)- Black soldier fly is a beneficial insect which has been used in simple systems, to treat organic waste efficiently and rapidly, and to produce animal feed ingredient and fertilizer as end products. These flies are naturally found in warmer parts of the globe. The incidence of Black soldier fly was recorded for the first time in Nepal in between April and May 2020 in the sub urban area of Chitwan District, Nepal. Identification of the insect was done in the Laboratory of Department of Entomology, Faculty of Agriculture, Agriculture and Forestry University, Nepal. Both adult and larval forms of the insect were identified based on the study of morphological characteristics of captured specimens using simple microscope and stereomicroscope. The record of this insect in Nepal opens up a new dimension for its use in bio-systems to treat organic waste and produce more sustainable ingredient for animal feeding, and rich fertilizer to be used in agriculture.
