abstract
Seasonal abundance of rice stem-borer and leaf-folder was monitored in rice during kharif 2016 at ICAR-National Institute of Biotic Stress Management, Raipur by erecting yellow stem-borer sex pheromone and light trap. Three species of stem-borer including yellow stem-borer, Scirpophaga incertulas, stripped stem-borer, Chilo suppressalis and white stem-borer, Scirpophaga innotata were found attacking rice, among them, Sc. incertulas dominated. First catch of female of yellow stem-borer in light trap appeared during 1^st week of August 2016 (31^st MSW) which caused 1.1% dead-heart, thereafter reached the first peak during 3^rd week of August 2016 (33^rd MSW) and second peak during 4^th of August 2016 (35^th MSW) which caused the dead heart of 3.60 and 3.83%, respectively. Leaf-folder damage was low throughout the crop period. Relative humidity and rainfall were positively correlated with trap catches while maximum (26.0 ⁰C to 29.3 ⁰C) and minimum (17.4 ⁰C to 25.5 ⁰C) temperature were positively correlated to damage caused by two insects.
