A kind of method of raising Lepidoptera insect

Abstract

The invention discloses a method for feeding lepidopteron. In the feeding process, a tray type net cage is used as a main feeding tool. The method comprises steps of collecting eggs, sterilizing, hatching larvae from the eggs, feeding the larvae, feeding pupas, feeding imagoes and the like, wherein gauze or plastic ropes are used as an oviposition substrate for collecting the eggs; the eggs are sterilized by using a formaldehyde solution with the volume concentration of 3-4%; the eggs are hatched and fed in an illumination incubator; the larvae are sterilized by using a sodium hypochlorite solution with the volume concentration of 8-12%; pupas feather in the tray type net cage; the feathering imagoes are continuously fed in the net cage and the eggs are collected and sterilized. The tray type net cage is simple and convenient to operate, the insects are effectively prevented from escaping and the cleaning can be carried out at any time; in the feeding process, eggs and larvae are disinfected by using different disinfectants, the disinfection effect is thorough and gentle, the bacteria are effectively prevented from mass propagation, and the hatchability of the eggs, the feathering rate of pupa are also improved, the hatchability of the eggs can be 95-96%, and the feathering rate of pupa can be 98%.

Description

technical field [0001] The invention relates to a test method for lepidopteran adult eclosion, egg collection, larva and pupa feeding, in particular to a method for raising lepidopteran insects. Background technique [0002] Lepidoptera is the second largest order of Insecta. Lepidoptera insects such as silkworm, tussah silkworm and castor silkworm are very important economic insects. Cordyceps sinensis, which is formed by the parasitization of bat moth larvae by fungi, is even more valuable Chinese herbal medicine; , cotton bollworm, armyworm, beet armyworm, etc. are important agricultural pests, causing huge economic losses every year. [0003] Lepidoptera insects need to go through four stages of eggs, larvae, pupae and adults to complete a generation. Larvae are usually raised with artificial feed, and the technology is relatively mature; adult insects must provide a large feeding space so that the male and female can mate before they can lay eggs and reproduce offspring...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned wooden cages or breeding boxes need to open the cage door frequently when changing food or collecting insect eggs during the breeding process. Not only is the operation cumbersome, but it is also easy to cause the adults to escape. It is often time-consuming and labor-intensive to catch the escaped adults in the laboratory. , and the feeding efficiency is relatively low

However, traditional rearing methods are difficult to control the degree of disinfection in the disinfection process of raising wooden cages or breeding boxes, often resulting in incomplete disinfection, resulting in a large number of bacteria and viruses, so that larvae, pupae, etc. are infected with bacteria and viruses. Therefore, the above disinfection process Defects often lead to low egg hatching rate, larval pupation rate, pupal emergence rate and adult survival rate, which is not conducive to experimental research and practical application.
