Sericulture is the science of silk production. In other words, sericulture deals with a series of events that include the rearing of the silkworms on mulberry plants, collection and processing of silkworm cocoons to extract raw silk fibers from them and the production of commercial silk. There are several commercial species of silk worms but very few are commercially exploited. Normally mulberry plants are used for rearing silk worms. The life cycle of a silk worm consists of four well-defined stages such as egg stage, larval stage (caterpillar), cocoon stage (pupae) and adult stage (moth).
