How to prevent the occurrence of small silkworms and lost silkworms, and increase silkworm cocoon yield?
The level of silkworm cocoon yield is not only related to the weight of a single cocoon, but to a large extent depends on the number of silkworms per sheet of eggs, so preventing the occurrence of small silkworms and lost silkworms during rearing is an effective measure to increase the yield per sheet of eggs. 1. Reasonable temperature and humidity. During the young silkworm stage, reasonable temperature and humidity should be maintained.

How to prevent the occurrence of small silkworms, "Fusangyi" silkworms and lost silkworms
The level of silkworm cocoon yield is not only related to the weight of a single cocoon, but also depends to a large extent on the number of silkworms per sheet of eggs. Therefore, effective measures should be taken during rearing to prevent the occurrence of small silkworms, "Fusangyi" silkworms and lost silkworms. The specific measures are as follows: 1. Carefully select good leaves. For collecting newly hatched silkworms and for the leaves used for 1st to 2nd instar silkworms, choose mulberry leaves that are suitably mature but on the tender side, fresh in leaf quality, and with a moisture content of no less than 75%. Avoid using old leaves and immature leaves, otherwise small silkworms are easily formed. During the middle feeding stage and the peak feeding stage, fresh and relatively tender mulberry leaves should also be chosen to feed the silkworms. 2. Suitable temperature and humidity. The optimum room temperature for 1st to 2nd instar silkworms
