A decade of advances in black soldier fly research: from genetics to sustainability

Black soldier fly (BSF), Hermetia illucens, is one of the most explored insect species mass-produced for feed, but also for food and technical purposes. Considering the rapid developments in both research and industrial production of this insect species in the last decade, this review intends to reflect on the most current scientific insights and define the future trends and needs for the most relevant associated research fields. The review reflects on the aspects of BSF production and reproduction, utilization of BSF biomass as components of animals' feeds and human food. It also provides reflection on genetics, microbiology and sustainability. The analysis identifies the need in future research associated with compositions of fungal and viral communities of insects and their environments and mapping the dynamics of BSF gut physiology and microbiota in varying conditions. High interest will be devoted to establishing genomic resources, to characterize genotypic diversity, and to harness its potential through selective breeding to improve BSF performance quantitatively and/or qualitatively. Further research will follow on the use of BSF for food and feed development, potentially for specific application cases, associated with animal gut microbiome improvement and antimicrobial properties of BSF biomass. The further in-depth exploration of the potential of BSF for waste biotransformation and the assessment of its circularity potential are also expected to be major focus points of research in the next decade.
