Abstract: Change in climate involving temperature variation influences the incidence of microsporidiosis in silkworm. As microsporidian disease in silkworm is epidemic, transovarially transmitted to progeny eggs and prevention of the disease is very vital in parental silkworm seed multiplication. The impact of different climatic conditions viz., summer, rainy and winter on the incidence of microsporidian disease in silkworm was studied at a sericulture Basic Seed Farm, at Mysore, Karnataka, India as a part of the regular monitoring and control of the disease carried out for a period 3 years (2008-10). The results indicated that the disease incidence was higher during the beginning of winter season (October-November) followed by rainy season (July-September) and the incidence was least in summer season (March-May). Correlation analysis showed that the incidence was correlated positively with humidity and negatively with temperature recorded from the study location.
