Antimicrobial peptides (AMPs) are the focus of this manuscript, as bioconservative molecules that constitute a major defense mechanism in many organisms.

Hermetia illucens is a remarkable organism adapted to life in a diverse, often highly polluted environment, and its resilience is largely attributed to amps.

The amp content of HI larvae extracts, which determines their activity, depends on the larval diet and the solvent used. This review presents in vitro studies on the effects of amps from Hermetia illucens on microorganisms and in vivo studies on the potential of Hi larvae meal as a feed supplement.
