Abiotic factors such as temperature and relative humidity are plays most vital role in an insect's growth and development. Abiotic factors must be considered in sericulture. Temperature and humidity show significant impact on cocoons of oak Tasar silk moth (Antheraea proylei) along with pupal diapause breakdown during storage in grainage. To achieve a high rate of emergence and fecundity, six different treatments were conducted using environmental chambers or climatic chambers. The current study focused on the influence of temperatures variation that is ranging from 18.5°C to 32°C and relative humidity levels ranging from 65-80 percent showed variation in the rate of emergence and fecundity.
