Visit to nearest sericulture farm and study the life cycle of silk worm.

1. The life cycle of the silk moth consists of four stages namely, egg, larva, pupa and adult. 

2. Thousands of eggs deposited by female moths are incubated artificially to reduce the incubation period. 

3. Larvae hatching out of eggs are released on mulberry plants to obtain nourishment from mulberry leaves. 

4. After feeding for 3 – 4 weeks, larvae move to branches of mulberry plant. 

5. The silk thread is formed from the secretion of salivary glands of larvae. 

6. Larvae spin this thread around themselves forming a cocoon, which may be spherical in shape. 

7. Ten days before the pupa turns into an adult, all the cocoons are transferred into boiling water. 

8. Due to the boiling water, the pupa dies in the cocoon and silk fibres become loose. 

9. These fibres are then unwound, processed and reeled. 

10. Different kinds of fabric are woven from silk threads.
