Muga Silk Assamese

Structural Mechanics

Muga silk, produced by the semi-domesticated silkworm Antheraea assamensis found primarily in the Brahmaputra valley, is known for its natural golden-yellow color and high durability. Practiced as a traditional cottage industry in Assam, Muga sericulture is protected under GI status. The sector faces climate challenges, as the outdoors-reared Antheraea silkworms are highly sensitive to rising ambient temperatures, pesticide drift from nearby tea gardens, and unpredictable monsoon patterns.

[Outdoors Silkworm Rearing (Antheraea assamensis)] 
    --> Extreme Climate Sensitivity (Vulnerable to Temp > 35°C) 
    --> Golden Cocoon Sourcing & Hand-Reeling 
    --> Traditional Handloom Weaving (Mekhela Chador) 
    --> Premium GI-Tagged Distribution

Data-Driven Metrics

  • Thermal Constraints: Temperatures exceeding 35°C cause high mortality rates in outdoor-reared Muga silkworms, reducing cocoon yields during extreme summer heatwaves.
  • Economic Value: Muga silk is highly valuable, with raw yarn commanding premium prices in international textile markets due to its limited production volume.
  • Pesticide Vulnerability: Insecticide drift from neighboring tea plantations has caused localized crop failures in adjacent sericulture clusters.

Strategic Vector

The Central Silk Board should fund indoor temperature-controlled rearing structures and develop pesticide-monitoring systems in sericulture zones, protecting vulnerable silkworm populations from environmental threats.
