Cordyceps sinensis host hepialus armoricanus larva generation cyclic breeding method

Abstract

The invention provides a cordyceps sinensis host hepialus armoricanus larva generation cyclic breeding method. The method includes the steps of natural growing pupa excavating introduction, larva forming, copulation, spawning, incubation, larva breeding, pupa introduction, larva forming, copulation, spawning and larva breeding generation circulation. Soil of a larva pupa chamber is prepared from,by weight, 40% of hepialus armoricanus origin place frozen earth, 20% of vegetable garden soil, 26% of high mountain humus, 10% of decayed grass roots, 3% of lime and 1% of fungus medicine, the pH value of the soil ranges from 5.5 to 6, and the water content is 40%. According to the cordyceps sinensis host hepialus armoricanus larva generation cyclic breeding method, natural wild pupae and moths are adopted as a first generation of pupae and moths for generation cyclic breeding, following next generations can be cyclically transformed with artificially bred larvae, pupa or moths do not need tobe caught in fields, and people can directly breed larvae for achieving generation cyclic breeding. The fungus medicine for resisting viruses and killing bacteria, fungi and pests is added into the soil of a pupa chamber and the larva pupa chamber, so that harm caused by the viruses, the fungi and pollution is reduced, and the yield is increased.

Description

technical field [0001] The invention relates to a generation-generation circulation feeding method for bat moth larvae, which are hosts of Cordyceps sinensis. Background technique [0002] Bat moth larvae are the basis for the growth of Cordyceps sinensis. Taxonomically, they belong to the bat moth species of the genus Batmothidae. There are more than 20 species of this species. Due to different growth areas, the species are also different. [0003] At present, there is a small amount of experimental artificial breeding of bat moth larvae in the main production areas of northern Cordyceps sinensis, most of which are still at the level of one-generation feeding management, and there is no report on generation-by-generation cycle feeding. If you want to raise again, you have to dig out natural pupal moths to hatch for the next generation to raise. The rate of authentic larvae is low, generally between 20-40%, and the cycle is longer. The larvae are easily infected with viruses...

[0003] At present, there is a small amount of experimental artificial breeding of bat moth larvae in the main production areas of northern Cordyceps, most of which are still at the level of one-generation feeding management, and there is no report on generation-by-generation cycle feeding

If you want to raise again, you have to dig out natural pupal moths to hatch for the next generation to raise. The rate of authentic larvae is low, generally between 20-40%, and the cycle is longer. The larvae are easily infected with viruses and other bacteria and fungi, causing larvae. , adult worms die, the survival rate of authentic products is low, and large-scale factory breeding cannot be carried out. Therefore, the production test and development of Cordyceps sinensis are seriously restricted.
