“…Unlike the frass of mealworms (Tenebrio molitor L.) and black soldier flies (Hermetia illucens L.), which have been the object of more numerous studies referring to their fertilizing potential, few studies have explored the use of cricket frass to amend soils for crops [22][23][24]. Butnan et al (2022) showed that combining cricket frass with Eucalyptus biochar improved the yield of Chinese kale (Brassica oleracea L.).…”

Cricket Frass Fertilizer (CFF) was tested for its efficiency and potential as a fertilizer on the growth of green beans (Phaseolus vulgaris L.) in central Madagascar from April 2020 to October 2020. We grew green beans experimentally for 93 days with seven different fertilizer treatments: NPK 200 kg/ha (0.47 g of N/plant), GUANOMAD (guano from bat) 300 kg/ha (0.26 g of N/ plant), CFF 100 kg/ha (0.12 g of N/plant), CFF 200 kg/ha (0.24 g of N/plant), CFF 300 kg/ha (0.38 g of N/plant), CFF 400 kg/ha (0.52 g of N/plant), and no fertilizer (0 g of N/plant). Three plant traits were measured: survival proportion, vegetative biomass, and pod biomass. The survival proportion of plants treated with the highest dose of CFF (400 kg/ha, 88.1%), NPK (79.8%), and GUANOMAD (81.2%) were similar, but plants treated with the former yielded significantly higher vegetative (35.5 g/plant) and pod biomass (11 g/plant). These results suggest that fertilizing green beans with CFF at a 400 kg/ha dose is sufficient for plant survival and growth, and improves pod production. In Madagascar where soil quality is poor, dependence on imported chemical fertilizers (NPK) and other organic fertilizer (GUANOMAD) can be reduced. Cricket Frass Fertilizer can be used as an alternative sustainable fertilizer for beans.

“…These residues include excrements, exuviae, undigested substrates, and dead insects and represent the main side stream of the process (Klammsteiner et al, 2020a). This so-called insect frass has been shown to have wide-ranging beneficial effects on plants and is mainly sold as organic fertilizer (Ferruzca-Campos et al, 2023; Houben et al, 2020; Menino et al, 2021). Depending on the farmed species and the substrate used to grow the insects, the general composition of frass can be highly diverse.…”

Insect farming has gained popularity as a resource-efficient and eco-friendly method of managing organic wastes by converting them into high-quality protein, fat, and frass. Insect frass is a powerful organic fertilizer, enriching the soil with essential plant nutrients and enhancing plant defense mechanisms through chitin stimulation. Given the importance of frass commercialization for many insect farmers and the use of increasingly diverse organic wastes as insect feedstock, the need for legal guidelines to enable clean production practices has emerged. The recent introduction of a legal definition for frass and heat treatment requirements by the EU commission marks a significant step towards standardizing its quality. However, frass composition is influenced by numerous factors, and little is known about the processes shaping its nutritional profiles and contributing to its maturation. Here, we analyzed the physicochemical, plant-nutritional, and microbiological properties of black soldier fly, yellow mealworm, and Jamaican field cricket frass from mass-rearing operations and assessed the impact of hygienizing heat treatment. Frass properties varied significantly across insect species, revealing concentrations of plant available nutrients reaching as high as 7000 μg NH4+, 150 μg NO2-NO3--N, and 20 mg P per g of total solids. Heat treatment affected microbial activity by reducing basal respiration and microbial biomass carbon, but also reducing viable counts of pathogenicE. coliandSalmonella sp.In terms of microbiome composition, alpha diversity showed no significant differences between fresh and heat-treated frass samples within each insect species, but significant distinctions were observed across the three insect species. The soil application of frass reactivated and boosted soil microbial activity, suggesting no long-term detrimental effects on microorganisms. These results further highlight the potential of insect frass as nutrient rich organic fertilizer, with promising benefits for soil health and nutrient cycling.

Organic wastes, including cheese whey, are generated in greater quantities each year, which require management that has economic and social implications. Current treatments of cheese whey do not allow for its complete degradation or utilization. In this context, black soldier fly larvae (BSFL) promise to degrade a variety of wastes while generating and accumulating value‐added products such as protein, fat that can be transformed into biodiesel, and fertilizer can be obtained from their residues. In this work, the aim was to evaluate the cultivation of BSFL as a biological treatment for the revaluation process of cheese whey, as well as the composition of the larvae and residue (FRASS) obtained for the subsequent extraction of value‐added products such as fat or protein. It was observed that cheese whey did not affect the growth of the larvae, on the contrary, it increased it (final weight of = 0.252 ± 0.003 g). The larvae biomass was composed of mainly of lipids (42.48 ± 1.26% dry matter) and protein (34.98 ± 0.72% dry matter). A fatty acid profile was also performed, which confirms that, due to their composition (Saturated fatty acids = 262.91 ± 34.81 mg/g; monounsaturated fatty acids = 85.29 ± 19.64 mg/g; polyunsaturated fatty acids = 63.68 ± 11.33 mg/g), these accumulated lipids can be extracted for biodiesel production. This is the first approach to the treatment and utilization of cheese whey through insects.
