India has a rich and complex history in silk production and its silk trade dates back to 2nd century B.C. India’s silks are known for their finery and artistic designs and distinct colours. India holds distinction of being the world’s largest consumer of pure silk in the world and is the second largest producer of raw silk after china.Many states in India such as Assam, Karnataka, Tamil Nadu, Kerela, Uttar Pradesh, Jammu & Kashmir, and Uttarakhand are producer of raw silk. In currentscenario changing global climateseems to be one of the major hindrance in the growth and development of silk wormBombyx Mori. Various climatic factors such as temperature,humidity,precipitation,light, airetc. bearsinfluence on the developmental process,any change in the ratio of these climatic factors may lead to pessimistic result. The present experimental analysis conducted in laboratory contemplates the role and influence of temperature and humidity on the growth of pupa from larvae of silkworm Bombyxmori.It is observed that mortality rate is leastat temperature 22 - 26 ºC and 80-85% of relative humidity. It is also observed that weight of pupa and shell reared at temperature 22 to 26ºCand 80-85 %relative humidity are more. In addition to this, the study accentuates the character of different environmental factors on embryonic development of silkworm and highlights the precision required during the silkworm life cycle. The study includes the steps to be taken for the management of climatic condition and to improved quantity and quality of silk production in future.
