The high quality hepialus larval rates in table 5 were ranked, wherein,
High quality hepialus larva rate = high quality hepialus larva number/sample number x 100%;
The feed proportioning conditions corresponding to the sorted feed are shown in the following table:
| Ordering of | Feed proportioning | High quality hepialus larva rate |
| 1 | 10G of potentilla anserina, 10g of polygonum aviculare and 10g of carrot | 82.0% |

According to the experimental example, uninfected hepialus larva is selected for experiment to determine the optimal feed, and according to the result, the optimal feed proportion is 10g of potentilla anserina, 10g of polygonum perfoliatum, 10g of carrot/golden buckwheat, and the recommended proportion is 5-10 g of potentilla anserina, 10-15 g of polygonum perfoliatum and 10-15 g of carrot/golden buckwheat by considering the actual filling condition and the raw material price condition in mass production.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
