Impact of Heat Treatment on the Microbiological Quality of Frass Originating from Black Soldier Fly Larvae (Hermetia illucens)

Insects, 2021
Since black soldier fly larvae (BSFL, Hermetia illucens) are being produced at substantial volumes, concomitantly large amounts of the resulting by-product, called frass, are generated.

Multiple lineages of Streptomyces produce antimicrobials within passalid beetle galleries across eastern North America

eLife, 2021
Some insects form symbioses in which actinomycetes provide defense against pathogens by making antimicrobials. The range of chemical strategies employed across these associations, and how these strategies relate to insect lifestyle, remains underexplored.

Glasshouse Evaluation of the Black Soldier Fly Waste Product HexaFrass™ as an Organic Fertilizer

Insects, 2021
The mass farming of the black soldier fly (BSF; Hermetia illucens L.), to produce insect-based feed for livestock and fish, results in considerable amounts of insect frass, which contains substantial amounts of organic matter and bioavailable nutrients ...

Partially replacing synthetic fertilizer with black soldier fly (Hermetia illucens) larvae frass enhances kale (Brassica oleracea var. sabellica) production

Technology in Horticulture, 2023
A by-product of insect farming is 'frass', which is the leftover excrement that can be high in essential minerals. The frass of black soldier fly (Hermetia illucens) larvae (BSFL) is increasingly gaining interest as a soil amendment, but information is ...

The Insects as a Workforce for Organic Fertilizers Production – Insect Frass

, 2022
Following the evolution of composting technology, the process of digestion of a biological substrate by insects (entomocomposting) represents the last stage; however, from its initial context of producing an organic fertilizer, the role of entomocomposting has been imposing itself (due to increasing demographic pressure) mainly in the safe disposal of ...

Plant Nitrogen Uptake From Insect Frass Is Affected by the Nitrification Rate as Revealed by Urease and Nitrification Inhibitors

Frontiers in Sustainable Food Systems, 2021
Insect protein production is considered a sustainable alternative to livestock protein which furthermore utilizes waste streams. Its production can have positive but also potentially negative environmental effects, which require evaluation.

Earthworms (Lumbricus terrestris L.) Mediate the Fertilizing Effect of Frass

Agronomy, 2020
With the forecasted dramatic growth of insect rearing in the near future, frass (insect excreta) has been increasingly considered a sustainable resource for managing plant nutrition in cropping systems and a promising alternative to conventional ...

An extract from the frass of swallowtail butterfly (Papilio machaon) larvae inhibits HCT116 colon cancer cell proliferation but not other cancer cell types

BMC Genomics, 2023
Background The frass of several herbivorous insect species has been utilised as natural medicines in Asia; however, the metabolite makeup and pharmaceutical activities of insect frass have yet to be investigated. Oligophagous Papilionidae insects utilise
