Method for breeding cerambycidae larvas by utilizing saw dust
The invention discloses a method for breeding cerambycidae larvas by utilizing saw dust, which comprises the following steps of: firstly, adding a soluble nutrient solution into the saw dust to prepare a breeding base stock, and then filling the breeding base stock into a nutrition bag; then perforating on the breeding base stock, and inoculating low-age cerambycidae larvas; secondly, controllingmoisture content of the breeding base stock and a temperature and humidity of air in a breeding environment, and optimizing breeding; and sixteen weeks after inoculating, breaking the breeding base stock open, sorting and gaining the cerambycidae larvas. The soluble nutrient solution comprises raw materials in percentage by mass as follows: 0.1 to 10% of yeast extract, 0.01 to 1% of glucose, 0.01to 1% of decavitamin, 1 to 10% of an adhesive, 0.01 to 0.1% of a preservative and the balance of water. The moisture content of the breeding base stock is 30 to 60%, the relative humidity of the air is 40 to 90%, and the temperature is 20 to 30 DEG C. A problem of environment pollution caused by incinerating and abandoning the saw dust, and cerambycidae breeding is promoted.
