Silkworm rearing is a crucial period to determine the high yield of silkworm cocoon. According to the physiological characteristics of silkworm, silkworm farmer should strengthen feeding and management.

In recent years, the main reason for the occurrence of silkworm disease is the poor awareness of silkworm farmers in disease prevention and prevention, and the prevention and control of light silkworms have led to the prevention and treatment of larvae before silkworm rearing, silkworm rearing, and silkworm rearing. In particular, this year due to the low temperature in the early period, the overall feeding of spring silkworm is delayed, and the large silkworm may encounter high temperature in the later period. Therefore, the majority of silkworm farmers should raise awareness to prevent the main body and implement comprehensive and thorough disinfection and disease prevention measures to the sericulture production. Throughout the entire process, the disinfection and disease prevention work was strengthened to minimize the losses caused by silkworm diseases.

When 70~80% of the silkworms are sleeping, it is advisable to increase the net and increase the time for adding nets to not more than 10 hours after sleep. Qingtou feeds in batches, satisfies food and sleeps, and resolutely eliminates disease and weak silkworms.

In silkworm rearing, they are accustomed to rearing small and large silkworms for rearing silkworms, especially in the later stage of large silkworms. The measures are insufficient, high temperature and hot weather are encountered, and effective measures are not adopted, which seriously affects the normal growth and development of silkworms. Therefore, during the silkworm period, we must pay attention to the work of ventilation and thin air, and expand the size of silkworms to 40 square meters after the second day of 5th instar, and feed the good mulberry, and create comfortable environmental conditions. So that children can eat mulberry, silkworm body health, normal growth and development.
