Ans: Sericulture, or silk farming, is the rearing of silkworms for the production of raw silk.
Life cycle of a silk moth:


1. Egg →2.First stage of larvae→3.Second stage of larvae→4.final stage of larvae→ 5.Pupa →6.Adult
The female silk moth lays eggs, from which hatch larvae which are called caterpillars or silkworms.
They grow in size and when the caterpillar is ready to enter the next stage of its life history called pupa, it first weaves a net to hold itself. Then it swings its head from the side to side and secrets fibre made of a protein which hardens on exposure to air and becomes silk fibre. Soon the caterpillar completely covers itself by silk fibres and turns into pupa. This covering is known as cocoon. The further development of the pupa into moth continues inside the cocoon.

Answer.


Life Cycle – Silk Moth:  Actually silkworms are not worms, but the larvae or caterpillars hatched from the eggs of the silk moth. The life history of a silk moth starts when a female silk moth lays eggs.

The larvae or caterpillars hatched from the eggs of the silk moth. These silkworms feed on fresh mulberry leaves the silkworm grows in size and then becomes a pupa.

In the pupa stage, it weaves a net to hold itself.  It then swings its head from side to side, secreting a fibre that hardens on contact with air. This fibre is made of a protein and becomes the silk fibre.

The caterpillar covers itself completely with silk fibre and turns into a pupa, this covering is known as the cocoon. The moth continues to develop within the cocoon. The silk thread or yarn is obtained from the silk moth’s cocoon.
