The research on varietal screening of rice against leaf folder, caseworm and grasshopper damage was conducted during 2019 in Rampur, Chitwan to study the host plant resistant of different varieties of rice under field condition. The experiment was laid out in RCBD with three replications and seven treatments namely i) Makawanpur -1 ii) Mansuli iii) Radha-4 iv) Ramdhan v) Sabitri vi) Sama Mansuli sub-1 and vii) sukkha-3. The experiment revealed that lowest population of leaf folder, caseworm and grasshopper was recorded in variety Radha-4 followed by Ramdhan. The experiment showed the yield loss was significantly lower in Radha-4 followed by Sabitri and Ramdhan due to leaf folder, caseworm and grasshopper. So Radha-4 and sabitri would be good option in rice production for reducing insect pest damage.
