There are many reasons for the occurrence of small silkworms and missing silkworms, such as the quality of mulberry leaves, feeding environment, pathogens, and extensive operations.
In order to prevent the occurrence of small silkworms and loss of silkworms, ants and 1 to 2 instar silkworm leaves must be mulberry leaves with suitable tenderness, fresh leaf quality and moisture content of not less than 75%. Avoid old and immature leaves. , otherwise it is easy to form small silkworms. According to the breeding standards to control the appropriate temperature and humidity, the temperature is too low or too high or low temperature and humidity are easy to make the silkworm body composition decreased to form a small silkworm. Silkworm seats should be thin, even and flat. The area of ​​silkworm silkworms of 1, 2 and 3 instar silkworms should reach 1.1, 2.2, 5.2 to 6 m 2 , respectively, in order to prevent silkworm heads from overtly affecting the silkworm larvae that cause small silkworms. Too large cutting leaves and excessive mulberry leaves are easy to lose silkworms. When expanding, you must keep the silkworm flat and don't overturn it. In order to improve the group's approval, it is possible to prevent them from becoming weak because of hungry sleep. In the feeding of 1~2 instar silkworms, lime espresso (three fresh limes and seven eschars) is often used before mulberry, which can promote silkworms to not eat remaining mulberry leaves and reduce the occurrence of lost silkworms.
