Feeding and probing behaviour of rice brown planthopper (BPH) Nilaparvata lugens (Stal.)

Brown plant hopper (BPH) Nilaparvata lugens (Stal.) is an important pest of rice and host plant resistance is the utmost component for managing this. The feeding and probing behaviour of this pest was studied on six selected highly resistant advanced rice breeding lines along with a resistant check (Ptb-33) and susceptible check (TN-1). After standard screening evaluation the damage score ranged between 0. 1 to 0. 5, 2. 4 and 9. 0, respectively. All selected highly resistant lines exhibited significantly lowest feeding and highest probing marks. Feeding values ranged between 4. 0 to 11. 45 mm² per female and probe number between 30. 4 to 42. 9 per female on test seedlings.
