Embodiment 1
[0060] 1. Preparation and cultivation of strains:
[0061] (1) Strain preparation: prepare potato sucrose agar medium or potato sucrose culture solution for subsequent use;
[0062] ①Preparation of slant seeds: wild cicadas collected from the source of Sanjiang in Yunnan Province were obtained through tissue separation and purification, and after transferring to tubes, they were cultured at 22°C for 5 days, and selected for future use;
[0063] ②Preparation of the primary seed: put the potato sucrose culture solution into the Erlenmeyer flask, put it in a sterilizing pot and sterilize it under the pressure of 0.15MPa for 30min, and put the spare slanted seed into the Erlenmeyer flask under aseptic condition after cooling , cultivated for 5 days at 22°C with an oscillation frequency of 130r / min, until a large number of mycelium balls appeared in the Erlenmeyer flask and then used for later use;
[0064] The ratio of the PSA medium used in this embodiment is per 1000ml of mediu...
