In order to understand seasonal incidence, crop loss estimation and management of yellow stem borer Scirpophaga incertulas (walker) on paddy, studies were conducted during 2015 at ZAHRS, College of Agriculture, Shivamogga. The highest incidence of dead heart and white ear was noticed during third week of April and third week of May. Maximum temperature had significant positive correlation whereas minimum temperature, sunshine hours and afternoon relative humidity had non significant positive correlation and in Kharif, the incidence was high during second and third week of September. Maximum temperature had significant positive correlation and minimum temperature, total rainfall, sunshine hours had non significant positive correlation. In pheromone trap, peak moth catches of 44.40 moths was recorded during fourth week of April and there was a significant positive correlation with maximum temperature, sunshine hours and minimum temperature. During Kharif, Peak catches of 35.20 moths was recorded during third week of September. Maximum temperature, sunshine hours exerted positive correlation.
