Black Soldier Fly (Hermetia illucens) Microbiome and Microbe Interactions: A Scoping Review
This scoping review examined all peer-reviewed literature on the microbiome of black soldier fly larvae, which are farmed worldwide to convert organic waste into biomaterials. Researchers found no evidence of a universally conserved core microbiome, as diet strongly shaped gut bacterial communities, though certain genera appeared frequently across studies regardless of diet. The review highlights the potential of gut-associated microbes as probiotics to improve larval fitness and bioconversion rates.
Black soldier fly (Hermetia illucens L.) as a high-potential agent for bioconversion of municipal primary sewage sludge
Researchers tested whether black soldier fly larvae could safely process municipal sewage sludge — a major waste management challenge — by feeding the sludge mixed with a standard insect diet to larvae.

Microplastics in the diet of Hermetia illucens: Implications for development and midgut bacterial and fungal microbiota
Researchers fed black soldier fly larvae diets containing PVC microplastics at various concentrations and found the insects could tolerate even high levels (20% of diet) without significant increases in death rates. The larvae ingested and reduced the size of the plastic particles, and while their overall gut microbial diversity remained stable, certain bacterial and fungal populations shifted. This suggests black soldier flies could potentially help process plastic waste, though the safety of using these insects as animal feed after plastic exposure needs further study.
Farmed insects for sustainable food systems
This thesis investigates farmed black soldier fly larvae as a sustainable food system component, examining nutrient flows during larval rearing on agri-food residues and pig manure, larval dietary preferences, incorporation of manure nitrogen into larval biomass, global warming potential, and principles for responsible use of farmed insects as livestock feed.
Plastics shape the black soldier fly larvae gut microbiome and select for biodegrading functions
Researchers found that black soldier fly larvae can adapt their gut microbiome to digest a wide range of plastics, shifting their microbial communities to favor biodegrading functions. This suggests the insects could serve as living incubators for discovering new plastic-breaking enzymes for industrial cleanup applications.
Gut microbiome of black soldier fly larvae for efficient use and purification of organic waste: An environmentally friendly development concept
This review examines how black soldier fly larvae and their gut bacteria can break down organic waste, including microplastics, heavy metals, and antibiotics. The larvae's gut microbiome plays a key role in degrading these harmful substances while converting waste into useful protein and fertilizer. This biological approach could help reduce the amount of microplastic-contaminated waste that enters the environment and food chain.

Researchers investigated how microplastics and salinity levels affect the ability of black soldier fly larvae (Hermetia illucens) to process food waste, finding that both factors can negatively influence larval growth, survival, and food waste degradation efficiency. The results highlight challenges for using this insect as a bioconversion tool in contaminated or coastal waste streams.
Examining the potential of plastic-fed black soldier fly larvae (Hermetia illucens) as "bioincubators" of plastic-degrading bacteria.
Researchers examined whether black soldier fly larvae (Hermetia illucens) fed on plastic waste can serve as 'bioincubators' for plastic-degrading bacteria, investigating how gut microbiota shifts in response to plastic-containing diets and whether these bacteria retain degradation activity.
Exposure of black soldier fly larvae to microplastics of various sizes and shapes: Ingestion and egestion dynamics and kinetics
Researchers studied how black soldier fly larvae, used to convert food waste into animal feed, interact with microplastics of different sizes and shapes. The larvae ingested microplastics along with their food but could not fully break them down, passing most of them through in their waste. This raises food safety concerns because if microplastics persist in the larvae, they could transfer up the food chain when the larvae are used as feed for livestock or fish.
Efficacy of Black Soldier Fly (Hermetia illucens) Larvae Meal as Feed on Growth Performance for Juvenile Javan Mahseer (Tor tambra)
