Answer 1

Answer:

Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, Bombyx mori (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm.

Answer 2

Sericulture: The rearing of silkworms for obtaining silk is called sericulture. The breeding and management of silk worms for the production of silk is known as sericulture. Different types of silk (e.g. mulberry silk, Tassar silk etc.) with different textures are obtained from different varieties of silk moths.

Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, Bombyx mori (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production.

Stages of production

Stages of production 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.
• It swings itself from side to side in a figure '8', distributing the saliva that will form silk.
• The silk solidifies when it contacts the air.
• The silkworm spins approximately one mile of filament and completely encloses itself in a cocoon in about two or three days. The amount of usable quality silk in each cocoon is small. As a result, about 2,500 silkworms are required to produce a pound of raw silk.[9]
• The intact cocoons are boiled, killing the silkworm pupa.
• The silk is obtained by brushing the undamaged cocoon to find the outside end of the filament.
• The silk filaments are then wound on a reel. One cocoon contains approximately 1,000 yards of silk filament. The silk at this stage is known as raw silk. One thread comprises up to 48 individual silk filaments.
