Feeding matrix suitable for 3-instar or older ghostmoth larvae and cultivation method

Abstract

The invention relates to a feeding matrix suitable for 3-instar or older ghostmoth larvae and a cultivation method. The feeding matrix comprises vermiculite, river sand and coco coir, the raw materials are prepared into different proportions, so that the growth and development of the ghostmoth larvae in different ages can be met. According to the cultivation method disclosed by the invention, thefeeding matrix is utilized, and regular replacement and supplement of the feeding matrix is carried out until the ghostmoth larvae completely pupates. The method disclosed by the invention has the beneficial effects that the aged larvae can be subjected to pupation, eclosion and mating and oviposition through feeding, so that a stable ghostmoth source is provided for indoor feeding; the vitality of the bred ghostmoth larvae larvae is guaranteed.

Description

Technical field [0001] The invention belongs to the field of larvae breeding of Hepalpis moth, and specifically relates to a rearing substrate and breeding method suitable for larvae of Hepalpis moth at 3 instars and above. Background technique [0002] Cordyceps is a special rare Chinese medicine in my country, mainly distributed in alpine meadow areas such as Tibet, Qinghai, Sichuan, Yunnan and Gansu. The formation of Cordyceps is closely related to altitude, vegetation, temperature and humidity, light, air pressure and rain. The growth conditions are very harsh, and due to the degradation of the plateau ecological environment and man-made over-excavation, the output of Cordyceps has dropped significantly. Therefore, the artificial production of Cordyceps has been carried out. Cultivation will become an important trend in the development of Cordyceps sinensis industry [0003] Large-scale breeding of insect sources is the primary key point for the artificial cultivation of Cordy...

AI Technical Summary

Problems solved by technology

[0004] Under natural conditions, bat moth larvae live in alpine meadow soil. In order to simulate its wild environment during breeding, alpine meadow soil in production areas is often used as the feeding substrate for bat moth larvae. The environment is severely damaged, and the cost of excavation and transportation is high; and if only nutrient-rich alpine meadow soil is used, it will cause substrate infection and cause the bat moth larvae to be harmed by the disease

At the same time, the vigor of bat moth larvae after leaving the original growth environment is reduced, mainly manifested as deformity or direct death in the process of prepupation and pupation of old larvae, resulting in the inability to obtain enough adults or the inability of adults to mate and lay eggs. Complete the life cycle of the bat moth and provide a large and stable supply of bat moth larvae
