Conditions and main technical requirements for co-rearing of young silkworms
First, the purpose of co-rearing young silkworms, as the saying goes, "raise half of the young silkworms", which fully illustrates the importance of raising young silkworms. The purpose of the co-rearing of young silkworms is to enhance the physique of young silkworms to ensure the safety of large silkworms and to achieve high quality and high yield of cocoons. The advantages of small silkworm co-rearing are as follows: (1) it is beneficial to realize scientific sericulture, adopt advanced sericulture technology and facilities, promote the neat development and strong physique of young silkworms, provide guarantee for large silkworm rearing, and lay the foundation for high and stable cocoon production. (2) it is beneficial to disinfection and disease prevention. Overcome the resistance of young silkworms to adverse environment

Benefits of co-rearing young silkworms
Silkworms generally go through 4 sleep and 5 years old from hatching to cocooning. The 1st and 3rd instar is called small silkworm, and the 4th and 5th instar is called big silkworm or strong silkworm. The young silkworm period is the period of enriching the physique and the foundation of the whole silkworm period. The young silkworms are well reared and the silkworm body is strong, which can enhance the resistance to adverse environment and pathogens in the big silkworm stage. It is conducive to a bumper cocoon harvest. Therefore, raising young silkworms is the key to a bumper cocoon harvest. (1) it is convenient to carry out scientific sericulture: the juvenile silkworm requires higher temperature and humidity, and there must be a special person to adjust the temperature and humidity day and night.

How to prevent the occurrence of young silkworms and lost silkworms and increase the yield of silkworms?
The cocoon yield is not only related to the weight of single cocoon, but also largely depends on the number of larvae and lost silkworms, so it is an effective measure to prevent the occurrence of young silkworms and lost silkworms in the process of rearing. Reasonable temperature and humidity should be kept at a reasonable temperature during the period of young silkworms.

Disinfection and disease prevention in young silkworm stage and its key techniques
The "disinfection and disease prevention" in the co-rearing of young silkworms must be carried out all the time, and seriously grasp the technical keys of the three links of disinfection before silkworm disinfection, disinfection during silkworm period, and ending disinfection: first, disinfection before silkworm. Based on the principle of comprehensive and thorough, seeking practical results, on the basis of comprehensive cleaning, targeted agents are used for disinfection, and at the same time, the management after disinfection is strengthened. It should be noted that: 1, the quality of cleaning water should be good, it is strictly forbidden to wash silkworm tools in dead ditches, ponds and rivers; 2, the garbage cleaned should be concentrated.

Cutting leaves to feed silkworms to seek advantages and avoid disadvantages

In the production of sericulture in rural areas, some silkworm farmers are afraid of trouble and save trouble, and the whole leaves are still used to feed silkworms in the young silkworm stage, resulting in uneven development of young silkworms and serious waste of mulberry leaves. (1) to avoid the loss of the head of the small silkworm, especially the whole leaves of the 1st instar silkworms, the remaining mulberry that has not been eaten by the silkworms often shrinks and curls into a tube, wrapping part of the silkworms among them, while the young silkworms move.

Causes and Preventive measures of Silkworm poisoning
In the process of sericulture, poisoning sometimes occurs, which affects the growth and development of silkworms and causes a large number of deaths. Therefore, silkworm farmers must pay attention to it and take measures to avoid loss. 1. Gas poisoning silkworm eggs green stage or young silkworm one or two instar stage, the temperature of silkworm room is low, need to be heated. If coal products are used for heating, and there are no exhaust facilities on the coal stove, the toxic gases such as carbon dioxide, hydrogen sulfide and carbon monoxide accumulate in the silkworm room, which can cause poisoning of silkworm eggs and silkworms. Bombyx mori eggs are poisoned during the green stage and are prone to dead eggs or uneven hatching.
