Effect on Productivity of Silk (Antheraea Mylitta) Due to Changes Environmental Factors in Ambikapur Surguja District, Chhattisgarh

Abstract

Ambikapur is a city is Surguja district of Chhattisgarh. The oldest districts of the Indian state of Chhattisgarh in the east. Central Indian Ambikapur is also the divisional head quarters of Surguja district which consists of the five districts of Surguja, Koriya, Balrampur, Surajpur and Jashpur.

In current issue changing global climate seems to be one of the major hindrance in the effect on productivity of silkworm Antheraea mylitta. Various climatic factors such as temperature, humidity, light, air, wind etc. The present experimental analysis conducted in environment factors the role and influence of temperature and humidity in the growth of pupa from larvae of silkworm Antheraea mylitta. It is also observed that weight of pupa and shell reared at temperature 22-26 degree centigrade and 80-85% relative humidity are more. The present observation of the effect on productivity of silk due to environmental factors in Ambikapur district Surguja. The study includes the steps to be taken for the management of condition and improved quality and quality of silk production in future.
