Rearing Oak Tasar silkworms (Antheraea proylei and Antheraea mylitta) involves a series of carefully managed steps to produce Tasar silk, a type of wild silk known for its durability and unique texture. Here's a detailed description of the method of rearing Oak Tasar silkworms:
1. Host Plant Cultivation:
The first step in Oak Tasar silkworm rearing is the cultivation of host plants, primarily oak trees (such as Quercus serrata, Quercus griffithii, and Quercus leucotrichophora). These trees are grown in designated forest areas or plantations to provide leaves for feeding the silkworm larvae.
2. Collection of Silkworm Eggs:
Silkworm eggs are collected from naturally occurring populations of Tasar silk moths or from silkworm rearing centers. The eggs are carefully gathered and stored under controlled conditions until they are ready to hatch.
3. Hatching of Silkworm Eggs:
The silkworm eggs are placed on specially prepared racks or trays under controlled temperature and humidity conditions to stimulate hatching. Upon hatching, the tiny silkworm larvae emerge from the eggs and are ready to feed.
4. Feeding and Rearing of Silkworm Larvae:
The newly hatched Oak Tasar silkworm larvae are transferred to trays containing fresh oak leaves. The larvae feed voraciously on the oak leaves, growing rapidly through successive molting stages (instars). During this period, the rearing environment is carefully monitored and maintained to ensure optimal conditions for larval growth.
5. Molting and Growth Stages:
As the Oak Tasar silkworms grow, they undergo several molting stages (instars) where they shed their old skins to accommodate their increasing size. Adequate space, ventilation, and regular supply of fresh oak leaves are crucial during these stages to support healthy development.
6. Spinning of Tasar Silk Cocoons:
After completing their larval growth stages, the mature Oak Tasar silkworms enter the spinning phase. They climb onto specially prepared frames or branches and begin spinning their characteristic golden-yellow cocoons using silk threads secreted from specialized glands.
7. Harvesting and Processing of Tasar Silk Cocoons:
Once the Tasar silk cocoons are fully formed and the silkworms have completed their life cycle, the cocoons are carefully harvested. The cocoons are then subjected to a process called "degumming," where the silk is extracted and processed to remove sericin (silk gum) and other impurities.
8. Weaving and Finishing:
The extracted Tasar silk fibers are spun into yarn and dyed to achieve desired colors. Skilled artisans weave the Tasar silk yarn into various textile products such as sarees, scarves, and fabrics known for their strength, sheen, and aesthetic appeal.
Benefits of Oak Tasar Silkworm Rearing:
In summary, rearing Oak Tasar silkworms involves a combination of ecological conservation, traditional knowledge, and skilled craftsmanship to produce high-quality Tasar silk with unique characteristics and cultural significance. This centuries-old practice continues to contribute to the socio-economic development of regions where Tasar silk is produced.
