Exploring interkingdom communication: the case of black soldier fly mass-rearing

Interkingdom communication through volatile organic compounds influences interactions among organisms at a level often imperceptible to humans. Artificial settings that depend on the biotechnical exploitation of biological processes, such as the rapidly expanding sector of insect farming, are strongly affected by this often-overlooked multiway communication. Here, we aim to portray the significance of interkingdom communication influencing insect behavior. We use the black soldier fly (Hermetia illucens) as a model system to introduce the necessary actions to improve our understanding of communication between insects and microbes. Successful exploration of this phenomenon could transform the bioeconomy by improving insect mass-rearing processes and enhancing insect welfare. By interlocking behavioral and molecular ecology, chemistry, microbiology, and bioinformatics, we can uncover the molecular mechanisms underlying these interactions and develop practical applications for improved industrial practices. Future work should focus on pursuing research avenues to untangle the interwoven nature of insect behavior and microbial communities.
