What is meant by the term rearing of silk worms?

Answer 1

Cultivation of silkworms for the purpose of harvesting the silk from their cocoons.

Silkworms eggs take about ten days to hatch. They eat continuously. They have a preference for White Mulberry having an attraction to the mulberry oderant cis-jasmone.

After they have molted four times (i.e., in the fifth instar), their bodies turn slightly yellow and their skin becomes tighter. The larvae enclose themselves in a Cocoon of raw silk produced in the salivary glands that provides protection during the vulnerable, almost motionless pupal state.

The cocoon is made of a thread of raw silk from 300 to about 900 meters (1,000 to 3,000 feet) long. The fibers are very fine and lustrous, about 10 micrometers (1/2,500th of an inch) in diameter. About 2,000 to 3,000 cocoons are required to make a pound of silk.
