Silkworms were domesticated before the Xia Dynasty. Silkworm is cultivated from mulberry pests and has created sericulture technology. There was a "mother silkworm" in the Shang Dynasty, who was a silkworm official. In Oracle Bone Inscriptions, the silkworm god and Shangjiawei sacrificed together, and they respected silkworm affairs very much.

At that time, there were four kinds of silkworms: cup silkworm (Ailanthus altissima silkworm), thorn silkworm, chestnut silkworm and mosquito silkworm, also known as snail silkworm. Both wild silkworm and silkworm are polygenic, and gradually evolved into diploid and univalent, mainly three-dormancy silkworm.

The Zhou Dynasty had a "silkworm-loving" system, and both emperors and vassals had "male silkworm rooms". Bath in February in the summer calendar and start sericulture on the first day of March. They have a certain understanding of silkworm growth patterns, such as bathing, the emergence of ants, silkworm dormancy, pupation, cocoon formation and moth transformation. There are records of Song Dynasty (foil), planting (silkworm frame), basket (silkworm plaque) and shed (reed mat) on silkworm rearing tools.

Extended data:

On the basis of traditional sericulture technology, all localities attach importance to seed production. In the Qing Dynasty, Jiangsu, Zhejiang, Sichuan, Hunan, Hubei, Guangdong, Guizhou and other places had local silkworm varieties suitable for local ecological conditions, among which Yuhang, Xinchang and Xiaoshan in Zhejiang were famous, and later became the manufacturing bases of modern silkworm eggs.

Technically, the high-rise shed cluster is used by the upper clan, catching with the times and avoiding the ground cluster. "Dry export" was improved to "burn silkworms instead of cocoons". Open the leaves when you sleep for three times, and eat the leaves two or three times to preserve the mulberry leaves, which are tough and shiny. When the leaves are few, you can feed the silkworms with white rice flour mixed with mulberry leaves, which is white and tough.

Pick autumn mulberry leaves, dry them in the sun, grind them into fine powder and put them in a dry place. When raising silkworms, the leaves are wet when it rains, so this kind of leaf powder can be mixed with people, which has the effects of burning wet, easily satiating and saving leaves. These are all good ways to replace food with feed.

From 65438 to 0898, Hangzhou established a sericulture science museum, learned from foreign sericulture experience and theory, eliminated particle disease, and bred a number of new varieties such as Zhu Qing, Xinyuan, Zhu Gui and Hongqing with new methods, and bred the earliest improved variety Qinggui in China, which occupied a large proportion at that time.
