Seasonal and relative abundance of stem-borer and leaf-folder in wet land rice eco-system

RK Murali Baskaran, KC Sharma and Jagdish Kumar

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 1st week of August 2016 (31st MSW) which caused 1.1% dead-heart, thereafter reached the first peak during 3rd week of August 2016 (33rd MSW) and second peak during 4th of August 2016 (35th 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.
