It is necessary to prepare the silkworm room, silkworm tools and mulberry leaves first. After the silkworm tools and the silkworm room are thoroughly disinfected, the silkworm eggs are hatched in a warmer environment in spring and summer. After the young silkworm is born, it can be fed with fresh mulberry leaves that have been cut into small pieces. If there is water on the mulberry leaves, it is necessary to dry them and keep the temperature of the silkworm room at 27℃. After the second instar, the temperature can be appropriately reduced. Usually, when the silkworm is 4 years old, it will start to form cocoons, and when the cocoons are peeled off, the silkworm chrysalis can be obtained.

The shape of the silkworm moth is similar to that of a butterfly. It has white scales, a small spherical head, bulging compound eyes and antennae, and three pairs of feet and two pairs of wings in the chest. However, because the two pairs of wings are small, it has lost the ability to fly. Usually, when the silkworm moth flaps its wings, it does not mean flying.

Matters needing attention in silkworm pupa culture

After the silkworm eggs are bought back, it is necessary to disinfect the breeding environment first. It is suggested that concentrated chlorine is the best. On the one hand, there will be no chlorine residue, on the other hand, it will not cause any great harm to the silkworm chrysalis. After disinfection, the environment should be sealed and the silkworm eggs can be put in after full disinfection.

When the silkworm chrysalis grows to the big silkworm stage, the feeding work can be directly put on the silkworm tree at this time. Of course, during this period, there is a period of adaptation, and when it is well adapted, the big silkworm will eat mulberry leaves on the silkworm tree and grow naturally. In addition, if it is found that there are almost no mulberry leaves on the silkworm tree for the silkworm to eat, it is necessary to pick up the silkworms from the silkworm tree one by one, put them in a basin, and then distribute them to the rich position of mulberry leaves.
