Cocoon collection and sale of silkworm
1. The suitable time for cocoon collection: after the cocooning of mature silkworm, molting and pupation, with the development of pupa, the skin becomes hard and the skin color becomes darker, when the skin color changes to yellow, it is the suitable time for cocoon collection. The spring silkworm period is 6-7 days after the upper cluster. The summer and autumn silkworm period is 5-6 days after the upper cluster, and the late autumn silkworm period is 7-8 days after the upper cluster. The cocoon is picked too early, the silkworm has not yet pupated, the hairy foot cocoon is not easy to be evenly baked during cocoon drying, the cocoon quality is reduced, and the hairy foot cocoon is easy to seep the dirt out of the cocoon layer during cocoon cooking, which makes the color of raw silk worse.

The law of cocooning in silkworm spinning
The life of silkworm goes through four stages: egg, larva, pupa and adult. The larval stage of silkworm is called the stage of silkworm baby. Sericulture usually refers to the rearing of larvae. The larvae go through four molting times from hatching to cocooning. As a result, the process of the larva is divided into five instar stages. For a period of time before molting, silkworms do not eat or move, which is called sleeping. From the first to the fourth instar, the silkworm sleeps four times, and the fifth instar silkworm no longer sleeps in the later stage, but forms a cocoon and pupates in the cocoon, thus completing the larval stage of the silkworm. The newly hatched silkworm is called ant silkworm, which has just molted its skin.
