Introduction to Sericulture

The word Sericulture is derived from the Greek word ‘Sericos’ meaning ‘silk’ and ‘culture’ meaning ‘rearing’. It is the process of rearing silkworms to get the final production of silk, which is the yarn obtained out of cocoons spun by certain species of insects.

Importance of Silk Production in India

India is the second largest producer of silk in the world. As per IBEF, among the four varieties of silk produced in 2024-25, Mulberry accounted for 75.8%, Tasar 4.58%, Eri 19.18% and Muga 0.56% of the total raw silk production of 41,121 Metric Tonnes in the  FY25. As of Fy25 the sericulture sector offers employment to around 9.76 million people, especially in rural and semi-urban regions. Additionally, sericulture activities are widely dispersed across approximately 52,500 villages.

Silk production is an important practice in India due to several reasons:

• Sericulture is an Agro-based rural industry with large labour involvement and high-income generation potential.
• It is one of the most beneficial types of industry for marginal and small-scale farmers.
• Women from rural areas also participates in sericulture which leads to increase in women empowerment.
• Mulberries require less water, so it is beneficial for farmers to grow this type of silk in low rainfall areas.
• It gives self-employment opportunities to the youth in rural areas.
• Silkworms and mulberries have many pharmaceutical properties.
• Many by-products are obtained from sericulture activities.

Types of Silkworms

• Mulberry Silk
• Eri Silk
• Tasar Silk
• Muga Silk

India is the only country to produce all four types of silk. The following are the four types of silkworms. Let’s understand each in detail.

Mulberry Silk

Mulberry silk comes from the silkworm, Bombyx mori L. Silkworms feed on mulberry leaves. Hence, the rearing of silkworms involves cultivation of mulberry trees, which provides a regular supply of leaves. These silkworms are completely domesticated and reared indoors. Mulberry silk has a pure white colour.

Eri Silk

Eri silk is the product of the domesticated silkworm, Philosamia ricini that feeds mainly on castor leaves. It is also known as Endi or Errandi, Eri is a multivoltine silk spun from open-ended cocoons, unlike other varieties of silk. A white or bright red silk is produced from this type.

Tasar Silk

Tasar silk is generated by the silkworm, Antheraea mylitta which thrives on food plants like Asan and Arjun. The rearing is conducted in nature openly. It is less lustrous than mulberry silk but has its own feel and appeal. It is usually produced in copper colour.

Muga Silk

Muga silk is obtained from semi-domesticated multivoltine silkworm, Antheraea assamensis. These silkworms feed on the aromatic leaves of Som and Soalu plants and are reared on trees like that of Tasar. It produces a bright, golden yellow colour.

Sericulture Process

• Moriculture
• Rearing of Silkworm
• Silk Reeling

Sericulture process consists of three steps. Let’s discuss each in detail.

Moriculture

Moriculture is the cultivation of mulberry plants. The leaves are used as food for silkworms. They can be grown by three different methods:

• Seed cultivation
• Root-grafting
• Stem grafting

There are basically three species cultivated in India namely Morus Alba, Morus Indica and Morus Nigra. But the most preferred one is Morus Alba because it grows well in loamy soil. Neutral pH is suitable for the healthier mulberry plants. The mulberry leaves can be taken up as a feed for silkworm after harvesting for the next cocoon stage.

Rearing of Silkworm

The rearing of silkworms begins with the laying of eggs by female silk moths. One single female silk moth produces 300-500 eggs. A 2% formalin solution is needed to disinfect the eggs. The eggs need suitable temperature so that young organism called caterpillar or silkworm break the shell and come out of the egg. The best time is when mulberry leaves bear fresh leaves. Silkworms feed on the mulberry leaves and grow. Along with mulberry leaves the silkworms are kept in clean bamboo trays for about 25-30 days. After some days, the cocoon is formed with a silk fibre and the caterpillar develops into a silk moth.

Silk Reeling

Silk reeling is the next step after silk rearing. The cocoons are kept under the hot sun or exposed to steam, to separate the silk fibres. This process is called stifling. Silk reeling is the process of separating silk threads from the cocoon of the silkworm. The harvesting of silk from these cocoons is the final stage of sericulture. The filament of threads is removed by using different machines to form reels. This spinning of silk fibres produces silk yarn or silk thread. By weaving the yarn, silk fabric is produced. This is the final silk produced for garment construction.

Major Silk Producing States in India

• Karnataka
• Andhra Pradesh
• Assam
• Tamil Nadu
• West Bengal

According to Central Silk Board of India, these are the top 5 silk producing states in India. Let’s discuss each in detail.

Karnataka - Karnataka holds the title of being India’s largest silk producer, with its prominent variety of Mysore Silk. Mulberry, Muga, Eri and Tasar silk are found here. Clothing items like sarees, dress materials, and scarves are famous in the state.

Andhra Pradesh – Andhra Pradesh is the second largest silk producer in India. The important silk production centres of Andhra Pradesh are in Dharmavaram, Pochampalli, Venkatagiri, and Narayanpet. Mulberry is the attraction, but other types of silk is also found here.

Assam – Assam ranks 3^rd in the silk production in India. It is the largest producer of Muga Silk in the world. Though Assam produces all 4 varieties of silk, major emphasis has been given in production of Muga and Eri Silk which are popularly Vanya Silk. Assam Contributes 95% and 65% of the country’s total Muga and Eri production respectively.

Tamil Nadu - Tamil Nadu stands at fourth position in India, practicing Mulberry sericulture. Rearing Eri silkworms for production of spun silk has also been picked up recently.

West Bengal – West Bengal holds the 5^th position in silk production in the country. The state is famous for producing Mulberry, Muga, Eri, and Tasar Silk. The famous items are sarees, shawls, and scarves.
