Abstract: In order to evaluate the resource utilization of black soldier fly to kitchen waste，the best production performance of  black soldier fly larvae to treat kitchen waste was screened, and the conversion of black soldier fly to kitchen waste under the best production performance was analyzed. The results showed that: the production performance of treatment of 3.6 kg kitchen waste by 100 g 7-day-old black soldier fly larvae was the best, the dry matter reduction rate of kitchen waste was 74.0%, and the dry matter conversion rate was 33.9% after 8 d coversion of kitchen waste. The content of crude protein and fat in worm was 45.1% and 48.1% respectively, which was 61.2% and 640% of the total protein and fat in the original kitchen waste. 61.3% of N and 71.4% of K in kitchen waste were transferred into the worm, 60.0% of P and 50.4% of Na were transferred into the feces. The pH, EC and organic matter content of the feces were 22.5%, 32.4% and 28.9% higher than that of the original kitchen waste, respectively, and the contents of N, P and Na were 13.5%, 130% and 92.9% higher, respectively. There was no significant change in K content. The pH, organic matter and N, P, K nutrient content of the feces meet the requirements of China's organic fertilizer standards. These results showed that the biotransformation of black soldier fly was a feasible and efficient way to treat kitchen waste.
