Rice leaf folder (Cnaphalocrocis medinalis Guenee) and yellow stem borer (Scirpophaga incertulas Walker) damage was found to be more in direct seeded rice (DSR) than transplanted (PTR) rice during rabi and Kharif seasons of 2012-13. Maximum leaffolder (5.03% and 13.01%) and yellow stem borer damage (5.54% and 13.49%) was recorded in DSR during rabi and Kharif season respectively. Sucking pests population like green leafhopper (Nephotettix virescens Distant) incidence was comparatively high in PTR (3.26 and 4.92/hill) and brown plant hopper (Nilaparvata lugens Stal) incidence (5.29 and 28.90 adults/hill) during both seasons respectively. Population of predators at two seasons remained high throughout the study period in PTR than the DSR except rove beetles (Paederus fuscipes Curt) whose population was more in DSR compared to PTR.
