Hermetia illucens has become one of the most promising species in the insect resources research field,which is commonly used in feed additives process and organic waste treatment area.In recent years,it is found that antibacterial peptides produced by Hermetia illucens immune system have prospective application values due to the broad-spectrum antibacterial activity against many kinds of microorganisms,including gram-negative bacteria,gram-positive bacteria and fungi.In order to improve the development and application of antibacterial peptides from Hermetia illucens,the molecular structure,antibacterial activity and mechanism,production preparation and application prospect were summarized in this paper,which may provide theoretical support and novel idea for the development and industrialization of high value-added products produced by Hermetia illucens.
