The change process of silkworm in cocoon is mainly divided into three stages. In the early stage, I will make my own nest and spin silk properly to ensure that it can be fixed, so that I can start hatching quietly. In the middle stage, you should molt once and gradually become a pupa. The pupa's shell is hard and most of it is brown. Later, the last molting was carried out, and most of them spit out a lot of liquid when they came out. The head comes out first, and then it will become a moth.
Silkworm farmers take cocoon seeds home, put them in a closed incubator, put each cocoon on and hang it in a string, waiting for it to break out. Silkworm moths are divided into male moths and female moths. After they became immortals, their tails crossed.
Method for cultivating cocoon and pupa
1. Selection of breeding ground: choose forest and fruit forest as breeding ground. The soil in the plot should not be too wet, and there should be no water, rats, insects and ants.
2. Collect the egg branches, and collect the egg branches in dense places in July and August.
3. Insert the egg branches into the clay pot and decide whether to bury them according to the situation of cicada eggs.
4. Burying: First, dig a pit 30-40 cm long near the trees in the cultivation area, bury 1 2 egg branches, and take out the eggs that are about to emerge from the egg branches in time.
5. Young silkworm chrysalis needs more nutrition, so it is necessary to increase feed during this period, and the excretion of silkworm chrysalis is also very large, so special attention should be paid to ventilation and cleanliness in the feeding room.
6. Daily management to ensure the good growth and development of trees and provide nutrition for cicada ants. Cicada ants will degenerate into adults after living underground for five years.
