Incubation method of Cordyceps sinensis host hepialus eggs

The invention provides an incubation method of Cordyceps sinensis host hepialus eggs. The method comprises the steps that: in a first incubation stage from hepialus oviposition to initial egg incubation, the eggs are incubated under the condition that the eggs are maintained to be contacted with water; in a second stage from the initial egg incubation to complete egg incubation, all the eggs are transferred to the waterless condition to be incubated; the whole incubation process is carried out under the constant temperature state; at the temperature of 8-12 DEG C, the hepialus eggs are incubated under the conditions that moisture is maintained in the early days and drying is carried out in the later days, the weight and the survival rate of larva are higher than those obtained by drying incubation under the natural condition or under the moisture incubation condition all the time; and incubation is carried out at the constant temperature of 10 DEG C, the hatching rate and the survival rate are higher than those obtained under the temperature-varying incubation condition and the other constant temperature incubation conditions.
