3. INTRODUCTION
The word Sericulture originated
from two French words seris – silk
and culture – rearing.
It is the rearing of silk worm for the
of raw silk.
It is an agro – based cottage industry.
Bombyx mori is the widely used species of silk
worm and it is intensely studied.
It involves the raising of blood plants for
silkworm , rearing of silkworm of cocoon for
production of yarn , etc.

4. HISTORY
 China is the birthplace of Sericulture.
 The mystery of silkworm cocoons was accidentally
invented by the Chinese empress Lei zu (Lady Hsi –
Ling – Shih) , wife of the emperor Shi Huang Di.
 When she was sitting under the shade of a Mulberry tree , a
cocoon covered insect fell into her cup of hot tea.
 The queen tried to save the insect , but the hot tea killed it by
loosening the cocoon.
 Instead she got a strong thread from the insect and this
admirable discovery earned her the name Goddess Of Silk
and Goddess Of Silkworm Rearing.

10. STAGES
 SILK MOTH LAY EGGS.
 EGGS HATCH & THE LAVAE FEED ON THE MULBERRY LEAVES.
 WHEN THE SILKWORM ARE ABOUT 10,000 TIMES HEAVIER THAN THE WHEN THEY
HATCHED THEN THEY ARE READY TO SPIN A COCOON.
 SILK IS PRODUCED INTO 2 GLANDS IN THE HEAD AND THEN FORCED OUT IN LIQUID FORM
THROUGH OPENINGS CALLED SPINNERETS.
 SILK SODLIDIFIES WHEN IT COMES IN CONTACT WITH THE AIR.
 SILKWORM SPINS APPROXIMATELY 1 MILE OF FILAMENT AND COMPLETELY ENCLOSES ITSELF
IN A COCOON IN ABOUT 2 OR 3 DAYS.
 DUE TO QUALITY RESTRICTION THE AMOUNT OF RAW SILK IN EACH COCOON IS SMALL.
 AS A RESULT, 5500 SILKWORMS ARE REQUIRED TO PRODUCED 1KG OF SILK.
 SILK AT THE COCOON STAGE IS THE RAW SILK.

11. OPPORUNITIES
 SERICULTURE PLAYS AN IMPORTANT ROLE IN EMPLOYMENT
GENERATION AND POVERTY ALLEVIATION.
 LARGE DEMAND AND POPULARITY OF HAND WOVEN SILKS
IN THE WEST.
 AVAILABILITY OF INDIGENOUS TECHNOLOGY AT LOW COST.
 SCOPE FOR ESTABLISHING THE LARGE PRODUCTION UNITS
AND ORGANISED UNITS.
 REGULAR AND QUICK RETURNS.
