Abstract: The present disclosure belongs to the technical field of organic wastewater resource utilization, and discloses a method for cultivation of black soldier fly larvae using high-concentration organic wastewater and trans-abdominal predigestion of plant-based feedstuff by black soldier fly larvae. The method comprises: collecting organic wastewater into a feed, inoculating a fermentation agent for fermentation, adding modified zeolite, folic acid, and choline chloride into the fermentation product to be stirred uniformly, and adding the organic wastewater to adjust a humidity of a mixture to obtain the feed; and feeding the black soldier fly larvae with the resulting feed, and adding the organic wastewater to maintain a humidity of the feed in a feeding process. According to the present disclosure, pre-treatment of the organic wastewater is not required, multiple use in feed formulation and feeding is achieved.
