An experiment was conducted in the laboratory to find out the impact of temperature and relative humidity on growth and development of C. cephalonica during, 2010-2011, revealed that the development period of male and female was maximum with a mean of 89.50 and 92.00 days at 20°C temperature and 40 per cent relative humidity, respectively. The maximum larval period of (70.10 days) was recorded at 20°C temperature and 40 per cent relative humidity; whereas, the maximum weight of full grown larva (51.00 mg) was recorded at 30°C temperature and 80 per cent relative humidity. The maximum pupal period of male (13.60 days) and female (14.40 days) were observed at 20°C temperature and 40 per cent relative humidity, while the higher weight of male (36.00 mg) and female (38.00 mg) pupa were observed at 30°C temperature and 80 per cent relative humidity. The maximum adult emergence of male (61.40%) and female (80.90%) were observed at 30°C temperature and 80 per cent relative humidity; whereas, the maximum adult longevity of male (16.30 days) and female (10.50 days) were observed at 20°C temperature and 40 per cent relative humidity. The maximum growth rate index of male (1.35) and female (1.64) were recorded at 30°C temperature and 80 per cent relative humidity, while minimum growth rate index male (0.39) and female (0.60) were observed at 20°C temperature and 40 per cent relative humidity.
