Sericulture: What is Sericulture, Importance and Species of Silkworm
India is the second-largest producer of silk in the world, after China. Other major silk-producing countries include Uzbekistan, Brazil, Japan, South Korea, Thailand, Vietnam, DPR Korea and Iran.
Sericulture is the process of cultivating silkworms and obtaining silk from them. It is an important agro-based rural industry that is increasing rapidly in India. Sericulture has the potential to generate high income for small and marginal farmers and also provides employment opportunities and women empowerment in rural areas.
In India, sericulture mainly includes the domestic silk moth caterpillar known as Bombyx mori. This is the most commonly used silkworm species in sericulture and plays a major role in silk production.
What is Sericulture
Sericulture is the process of producing silk through the rearing of silkworms. It involves cultivating silkworms and processing their cocoons to obtain silk fiber.
The word Sericulture is derived from:
1) The Greek word “Sericos”, which means silk
2) The English word “culture”, which means rearing or cultivation
Thus, sericulture refers to the cultivation of silkworms for silk production, also known as silk farming.
Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth Bombyx mori is the most widely used and intensively studied species in sericulture.
Importance of Sericulture
Sericulture plays an important role in rural development, employment generation, and agricultural sustainability. Some major benefits of sericulture are:
1) Sericulture helps in soil preservation, manure production, fuel sources, pollution control, integrated farming, and efficient land use.
2) Sericulture provides additional income opportunities for farmers.
3) It offers self-employment opportunities for educated unemployed youth in various sectors.
4) It is a budget-friendly occupation for small and marginal farmers and provides better economic returns.
5) Many by-products can be produced from sericulture activities.
6) Mulberry plants and silkworms have pharmaceutical and medicinal value.
7) Silkworms are used as a tool for genetic and biotechnological research.
8) Silkworm products can also be used in medicine and healthcare.
9) Most sericulture activities are village-based, which helps prevent migration from rural to urban areas in search of jobs.
10) It can also allow silkworm farming at home for feeding pets or other uses.
11) Sericulture provides continuous income to farmers throughout the year.
12) The mulberry plant can be grown as an intercrop with many plantations.
13) Both mulberry plants and silkworms have pharmaceutical value.
Species of Silkworm in Sericulture
There are several species of silkworm used in sericulture. The major types of silk produced in India include Mulberry, Tasar, Eri, and Muga silk.
1. Mulberry Silkworm (Bombyx mori)
The bulk of the commercial silk produced in the world comes from this variety, and generally silk refers to mulberry silk.
Mulberry silk is produced by the silkworm Bombyx mori, which feeds mainly on the leaves of the mulberry plant. These silkworms are completely domesticated and reared indoors.
In India, the major mulberry silk-producing states are:
1) Karnataka
2) Andhra Pradesh
3) West Bengal
4) Tamil Nadu
5) Jammu and Kashmir
These states together account for about 92% of the country’s total mulberry raw silk production.
2. Tasar Silk (Antheraea mylitta)
Tasar (Tussar) silk is copper-brown in colour and has a coarse texture. It is mainly used for furnishings and interior fabrics.
Tasar silk is produced by the silkworm Antheraea mylitta, which mainly feeds on Ber and Arjun plants. The rearing of these silkworms is conducted in natural conditions on trees in open environments.
In India, tasar silk is mainly produced in:
1) Jharkhand
2) Chhattisgarh
3) Odisha
4) Maharashtra
5) West Bengal
6) Andhra Pradesh
Tasar culture is an important source of livelihood for many tribal communities in India.
3. Eri Silk
Eri silk is also known as Endi or Errandi silk. It is a multivoltine silk variety and is commonly used for making traditional wraps known as chaddars.
Eri silk is produced by the domesticated silkworm Samia ricini, which mainly feeds on castor leaves.
In India, eri culture is mainly practiced in:
1) Assam
2) Other North-Eastern states of India
It is also found in Bihar, West Bengal, and Odisha.
4. Muga Silk
Muga silk is famous for its natural golden yellow colour. It is considered the pride of Assam and is unique to India.
This silk is produced by the semi-domesticated silkworm Antheraea assamensis.
These silkworms feed on the aromatic leaves of Som and Soalu plants and are reared on trees similar to tasar silkworms.
Muga culture is mainly practiced in Assam, where it forms an integral part of the local tradition and culture.
Muga silk is a high-value product used to produce items such as:
1) Sarees
2) Mekhela chador
3) Chaddars
Conclusion
Sericulture is an important agro-based industry that contributes to rural employment, economic development, and sustainable agriculture. India produces several types of silk, including mulberry, tasar, eri, and muga silk, each with unique characteristics and cultural significance. With increasing demand for natural silk worldwide, sericulture continues to play a vital role in supporting farmers and rural livelihoods.
