2. INTRODUCTION Sericulture is the cultivation of silk through rearing of silkworm. It is an agro based industry. It involves the raising of food plants for silkworm, rearing of silkworm for production of cocoons, reeling and spinning of cocoon for production of yarn etc. F or value added benefits such as processing and weaving.

12. USES OF SILK Mainly in textile industry for manufacturing garments Bags, telephone cable insulations, dyeing & screen printing

13. DISEASES Pebrene – caused by protozoan; larvae become pale yellow, size reduces & no yield Grasserie – skin of larvae rough & saliva becomes thick Flacherie – indigestion occurs & worm becomes thin, inactive & regenerates Muscardine –due to fungi; mortality occurs due to heavy rain & unhygienic

14. PRODUCTION OF SILK IN INDIA Leads 2 nd position in world Exporting 1/7 th of silk products to foreign countries Govt. of India constituted ‘Central S ilk B oard’ to protect interest of silk industry
