In order to avoid the occurrence of secondary cocoons, increase the cocoon rate and reduce the secondary cocoon rate are important links to further increase the economic benefits of sericulture households. The related technical points of preventing secondary cocoons are briefly introduced as follows: 1 strengthening the feeding and management of 1.1 small silkworms are covered with plastic film, which can not only keep the mulberry leaves fresh, but also promote the larvae to like to eat, which is beneficial to the larvae to eat and lift.

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.
