Abstract: China is a leading country of animal husbandry. Livestock and poultry breeding processes generate substantial quantities of manure, which adversely affects the atmosphere, water bodies, soil, and human health, thereby presenting a significant challenge to pollution control. The black soldier fly is a resource insect with advantages, such as rapid reproduction, a broad diet, and high absorption and conversion rates. Adult black soldier flies do not disturb humans, and both their larvae and frass have high utilization values. It can not only treat livestock and poultry manure harmlessly but also achieve resource recovery, offering broad application prospects. This paper summarizes the research progress of biotransformation of livestock and poultry manure by black soldier flies, reviews the basic principles and mechanisms of the biotransformation technology, elaborates on the performance and advantages of the biotransformation for resource utilization, analyzes the current status and challenges in the research and application of the biotransformation, and looks forward to its application prospects, with the aim of providing a scientific basis and research reference for the resourceful treatment of livestock and poultry manure.

Key words: black soldier fly, livestock and poultry manure, biotransformation, resource utilization
