Abstract

This invention belongs to the field of black soldier fly larvae farming technology and discloses a method for the live preservation of black soldier fly larvae. The invention discloses a nutrient solution comprising sugar, antibacterial agent, mineral salt, humectant, and antifungal agent; the sugar includes at least one selected from glucose, fructose, galactose, sucrose, lactose, maltose, and trehalose. This invention provides a nutrient solution that can be used for the long-term preservation of black soldier fly larvae. This nutrient solution can ensure that the physicochemical properties of the larvae, such as crude fat, crude ash, and crude protein, remain within normal ranges, significantly improving the survival rate and metabolic activity of the larvae and significantly extending their preservation period.
