What are the various steps involved in sericulture?
The various steps involved are: (i) Rearing of silkworms: A female silk moth lays hundreds of eggs at a time. Step 2: Thread extraction. Step 3: Dyeing. Step 4: Spinning.
What is sericulture and its stages?
The stages of production are as follows: The female silkmoth lays 300 to 500 eggs. The silkmoth eggs hatch to form larvae or caterpillars, known as silkworms. The larvae feed on mulberry leaves. Having grown and moulted several times, the silkworm extrudes a silk fibre and forms a net to hold itself.
