Problems solved by technology

However, after 3-5 generations of Cordyceps host insects reproduce under artificial conditions, various species degradation phenomena such as individual reduction, weakened mating ability, and reduced egg production will occur.

Embodiment 1

[0011] Embodiment 1 The investigation of the rejuvenation condition of the artificial breeding Cordyceps host insect species 1

[0012] 1. Selection of the original environment for Cordyceps cultivation

[0013] In the Cordyceps sinensis production area or a place with similar vegetation, temperature and humidity conditions to the Cordyceps sinensis production area, two plots were selected as the experimental plot of the control group and the experimental plot of the experimental group respectively. Surrounded by barbed wire. The slope of the rejuvenation base is preferably between 10-30 degrees, with good drainage; other shrubs except lawn plants are grown inside to avoid high-intensity sunlight and the harm of birds to adults.

[0014] 2. Transition management of caste rejuvenation

[0015] The 3rd generation of artificially bred little golden bat moths were collected respectively, 2 groups of 2000 larvae were reared artificially for 1-2 months, and 2 groups of larvae of t...

Embodiment 2

[0028] Example 2 The investigation of the species rejuvenation condition of Cordyceps host insects 2

[0029] 1000 larvae of the third generation Gongga bat moth and Xiaojin bat moth were respectively named Xiaojin group III and Gongga group III. Chrysanthemum ginger, carrots, human fruits, and a small amount of rhizomes of other plateau plants are raised in plateau humus (artificial substrates can also be used instead). The humus soil can form a ball by holding it firmly with the hand, and the humidity standard that it will not disperse when the hand is released. The raising temperature condition is 8-18 ℃. The stocking density is the amount of no more than 30 larvae placed in a unit feeding box (30cm long x 20cm wide x 15cm high). Because the mobility of the newly hatched larvae is weak, the range of activities is small, and the damage between individuals can be ignored, so the newly hatched larvae are suitable for intensive rearing. Intensive feeding of newly hatched lar...

Abstract

Disclosed is a culture method for natural species rejuvenation of an artificially bred cordyceps host insect and a technical solution of recycling a cordyceps host again after rejuvenated nurturing of one generation by placing the host in the wild. The key technique of the culture method for natural species rejuvenation of an artificially bred cordyceps host insect lies in that stage 2 to 4 artificially bred cordyceps host larvae are placed in and cultured in the native environment of the cordyceps host larvae until eclosion. The culture comprises two stages, namely, a transition period for adapting to the wild environment and a natural species exercise period. The present invention can effectively solve the problem of natural species degeneration of multi-generations of artificially bred cordyceps host insects.

Description

technical field [0001] The present invention relates to a method for feeding insects, more specifically to a method for artificially breeding the species of Cordyceps host insects for rejuvenation, the purpose of which is to solve the problem of species degradation in the process of large-scale artificial breeding of Cordyceps host insects for 3-5 generations . technical background [0002] Cordyceps sinensis [Cordycepssinensis (Berk.) Sacc.] alias Cordyceps, Cordyceps, summer grass winter worm. According to the most recent classification system, Cordyceps sinensis belongs to Fungi, Ascomycota, Ascomycetes, Sordariomycetidae, Hypocreales, Clavicipifaceae, Cordyceps. It is a complex of the sub-seat and the larva corpse of the ergot fungus Cordyceps sinensis [Cordycepssinensis (Berk.) Sacc.] parasitic on the larvae of the bat moth family insects. Artificial breeding and rearing of bat larvae are important links in the artificial cultivation of Cordyceps sinensis. So far, m...
