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.
Using aquatic insects as indicators of microplastic pollution in rice field ecosystems
Researchers used aquatic insect communities as bioindicators of microplastic pollution in rice field ecosystems, comparing insect diversity and abundance across fields with different levels of plastic contamination. Insect assemblages responded sensitively to microplastic loads, demonstrating their potential as low-cost monitoring tools.

Researchers tested yellow mealworm meal as a replacement for fishmeal in Nile tilapia diets, finding that adding the probiotic yeast Saccharomyces cerevisiae improved fish growth, gut health, liver condition, and immune function. This suggests insect-based feeds combined with probiotics can sustainably replace traditional fishmeal in aquaculture.
Chemical safety of black soldier fly larvae (Hermetia illucens), knowledge gaps and recommendations for future research: a critical review
This critical review examines the chemical safety of black soldier fly larvae, which are increasingly used as a sustainable protein source for animal feed. Researchers assessed how rearing substrates may introduce contaminants including heavy metals, pesticides, mycotoxins, and microplastics through bioaccumulation. The study identifies significant knowledge gaps in understanding how these contaminants transfer through the larvae into the feed chain and recommends targeted future research.
Modulation of Atlantic salmon (Salmo salar) gut microbiota composition and predicted metabolic capacity by feeding diets with processed black soldier fly (Hermetia illucens) larvae meals and fractions
Researchers fed Atlantic salmon different preparations of black soldier fly larvae — whole, de-fatted, or with exoskeletons removed — and found that full-fat larvae meal most favorably altered the gut bacteria in young salmon. The findings suggest that how insect feed is processed matters for fish gut health, which has implications for sustainable aquaculture practices.
Impact of heavy metals, microplastics, and food pathogens on black soldier fly larvae
Researchers fed black soldier fly larvae substrates contaminated with heavy metals, microplastics, and food pathogens to evaluate tolerance and bioconversion efficiency, finding that certain contaminants reduced larval performance and bioconversion rates with implications for insect-based waste recycling.
Diversity and relative abundance of aquatic insects of Dahaura Lake, Bahraich, U.P.
This ecological survey documented aquatic insect diversity and abundance in Dahaura Lake in India over a six-month period, finding 25 genera from multiple orders. Aquatic insects are bioindicators of water quality and could be used to assess the ecological impacts of microplastic contamination in freshwater ecosystems.
Enhancing the bioconversion rate and end products of black soldier fly (BSF) treatment – A comprehensive review
Researchers reviewed how black soldier fly larvae can efficiently convert organic waste — including food scraps and manure — into protein-rich feed, fertilizer, and biofuel, offering a sustainable alternative to conventional livestock farming. Their work highlights the larvae's potential to reduce plastic and food waste pollution while supporting global food security.
Black soldier fly larvae should be considered beyond their use as feedstuff
This review examines emerging applications of black soldier fly larvae beyond their established use as animal feed, including waste valorization and the extraction of bioactive compounds. The study highlights the growing interest in using these insects to process challenging waste streams, including organic materials contaminated with pollutants, and explores novel uses for the bioactive molecules they produce.
Sustainable Alternative Feed for Aquaculture: State of the Art and Future Perspective
Not directly relevant to microplastics — this review surveys sustainable alternative feed ingredients for aquaculture, covering plant-based proteins, by-products, and insects as replacements for fishmeal and fish oil.
Insect Models in Nutrition Research
This review examined insects as model organisms for nutrition research, covering their use in studying metabolic regulation, nutrient sensing, gut microbiome interactions, and diet-disease relationships. Insects offer advantages including low cost, rapid generation times, and genetic tractability, making them valuable for studying nutritional mechanisms relevant to human and animal health.
Occurrence Of Microplastics in Immature Aquatic Insects of Gua Musang Tributaries in Kelantan
Researchers investigated the presence and abundance of microplastics in freshwater immature aquatic insects, specifically caddisfly (Trichoptera) and dragonfly (Odonata) larvae, collected from two tributaries of Gua Musang in Kelantan, Malaysia. The study found that microplastics had accumulated in these larvae, raising concerns about microplastic transfer through aquatic food chains in the region.

A multi-levels analysis to evaluate the toxicity of microplastics on aquatic insects: A case study with damselfly larvae (Ischnura elegans)
Researchers conducted a comprehensive study of how polystyrene microplastics affect damselfly larvae, a sensitive freshwater insect, examining effects from the whole organism down to the molecular level. Higher concentrations of microplastics impaired the larvae's movement, disrupted their gut bacteria, and caused oxidative stress in their tissues. Since aquatic insects are an important part of freshwater food webs, their sensitivity to microplastics signals broader risks to ecosystem health.
