Background
The silkworm is commonly called a baby silkworm, also called a silkworm, and is one of the economic silkworm for spinning and cocooning by taking mulberry leaves as foodstuff. Belonging to the order Lepidoptera, family Bombycidae. The silkworm originates from China, the development temperature of the silkworm is 7-40 ℃, the breeding temperature is 20-30 ℃, and the silkworm is mainly distributed in temperate zones, subtropical zones and tropical zones.
The silkworm passes through silkworm eggs, newly-hatched silkworms, silkworm babies, silkworm cocoons and silkworm moths for a lifetime of more than forty days. The silkworm baby just hatched from the egg is dark in color and called as the silkworm, and the silkworm is full of fine hair, and the fine hair is not obvious after about two days. After the silkworm comes out of the shell, it begins to peel after a certain period of feeding, and the time of peeling is about one day, called "dormancy". After one-time peeling, the silkworm grows into second-instar larvae, and the silkworm needs to peel for four times to become fifth-instar larvae to start spinning and cocooning.
The traditional breeding mode is a family-type workshop breeding mode, and generally adopts a small bamboo basket for breeding, and the small bamboo basket has the advantages of simple structure, convenience in manufacturing, capability of being manually woven and low cost; the individual workshop type breeding is a full-artificial breeding method, the artificial operation from silkworm egg imagoes to cocoon collection is realized, the time and labor are wasted, the breeding efficiency is very low, the breeding is limited by seasonal conditions, the silkworm can be bred only at a specific time, the annual output of the silkworm cocoons is extremely low, the requirements of the current society cannot be met at all, and the individual workshop type breeding is gradually eliminated by the society.
