Abstract
The invention relates to a method for improving the survival rate of larvae of swift moth cultured at high and low altitudes. The method comprises using an intelligent constant temperature and humidity chamber to adjust different temperatures in different growth stages of 3-5-instar larvae. The method for improving the survival rate of the larvae of the swift moth cultured at high and low altitudes has the advantages of solving the problem of dried-up death of swift moth larvae in the 3-instar stage due to lack of water, invigorating the swift moth larvae in the 4-instar stage, reducing the infection rate of breeding environment and effectively improving the survival rate of 5-instar swift moth larvae.
Description
technical field [0001] The invention belongs to the technical field of artificial bionic cultivation of Cordyceps sinensis, and in particular relates to a method for improving the survival rate of bat moth larvae raised at low altitude. Background technique [0002] The first condition for the artificial cultivation of Cordyceps sinensis is to successfully raise the bat moth larvae under simulated natural growth environment conditions. It takes 4-5 years for the host bat moth to complete the development cycle under natural environmental conditions. The larvae like low temperature and humidity, and are not resistant to high temperature. If the temperature is higher than 20°C, they will die on a large scale. , When the soil moisture content is too large, it often climbs out of the ground and can survive for several days floating on the water surface. The larvae mainly gnaw on the roots of plants such as Polygonum cephalum, Polygonum villosa and little rhubarb, and also gnaw o...
