What is sericulture ? : 

What is sericulture ? Sericulture, or silk farming, is the rearing of silkworms for the production of raw silk. Amongst species of silkworms, Bombyx mori is the most widely used Silk is known as the queen of textile and “BIOSTEEL” because of its strength. See Video

Different Types of Silk

Sericulture – Historical Perspective : 

Sericulture – Historical Perspective China is said to be the origin of sericulture. The discovery of silk production by B. mori dates to about 2700 BC, although archaeological records point to silk cultivation much earlier. In India the cultivation dates back to 140 AD. Later it was introduced to Europe, the Mediterranean and other Asiatic countries. Sericulture has become one of the most important cottage industries in a number of countries like China, Japan, India, Korea, Brazil, Russia, Italy and France. Today, China and India are the two main producers, together manufacturing more than 60% of the world production each year.

Sericulture – Stages of Production : 

Sericulture – Stages of Production The silk moth lays eggs. When the eggs hatch, the caterpillars are fed mulberry leaves. When the silkworms are about 25 days old, they are 10,000 times heavier than when they hatched. They are now ready to spin a silk cocoon. The silk is produced in two glands in the silkworm's head and then forced out in liquid form through openings called spinnerets. The silk solidifies when it comes in contact with the air. The silkworm spins approximately 1 mile of filament and completely encloses itself in a cocoon in about two or three days but due to quality restrictions, the amount of usable silk in each cocoon is small. As a result, 5500 silkworms are required to produce 1 kg of silk. The silk is obtained from the undamaged cocoons by brushing the 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 consists of up to 48 individual silk filaments.

Sericulture – Opportunities : 

Sericulture – Opportunities Sericulture being cottage industry plays an important role in employment generation and poverty alleviation. It is one of the most profitable activities in rural sector. Availability of indigenous technology at low cost Regular and quick returns. Large demand and Popularity of hand woven silks in the west. Strong domestic demand coupled with use of silk garments on festive occasions. Large production gap to meet the domestic demand. Scope for establishing the large production units and organized sector. Effective utilization of the Byproducts will be more effective.
