Sericulture Life Cycle of Bombyx mori & Silk Biochemistry | BSc Zoology V Sem | NEP2020 | CUET PG

In this video, we explore the world of Sericulture (Applied Entomology). This comprehensive lecture covers the history of silk production, the complete life cycle of the Mulberry Silkworm (Bombyx mori), and the detailed molecular biochemistry of silk proteins. This session is designed for B.Sc. Zoology semester exams and CUET-PG Zoology/Life Sciences preparation in Hindi. Key Topics Covered in this Video: History of Sericulture: Origin in China (Empress Leizu) and its economic importance in India. Taxonomic Position: Classification of Bombyx mori (Family: Bombycidae). Life Cycle of Silkworm: Complete metamorphosis (Egg → Larva → Pupa → Adult). Deep dive into the 5 Larval Instars and 4 molting stages. Silk Gland Anatomy: How modified labial glands produce the liquid silk thread. Biochemistry of Silk: Structural breakdown of Fibroin (inner structural protein rich in Glycine and Alanine) and Sericin (the outer gummy, water-soluble protein envelope). #bsczoology #msczoology #sericulture #bscbiology #cuetpgzoology #wwhacademy
