Six differential varieties along with standard checks were evaluated for donor validation against rice brown plant hopper at glasshouse, Department of Entomology, IGKV, Raipur during 2013- 14. All the differentials were resistant to Raipur BPH population. Among the differential tested, ARC 10550 exhibited list plant damage score (0.64) followed by Sinna Sivappu (0.75). Honeydew excretion values were minimum in Sinna Sivappu (15.3 mm2) followed by Rathu Heenati (15.8 mm2). The average probing marks were maximum in Sinna Sivappu (38.3) followed by Rathu Heenati (30.7) which were significantly higher than TN1, while nymphal survival value was minimum in variety INRC 3021 (29.21%). All the differentials showed resistant reaction in all the tests performed against Raipur population. These differentials were designated as the potential donors for BPH resistance.Keywords

Biology of Sesamia inferens i.e., fecundity, incubation period, larval period, pupal period and longevity of adult were observed on maize hybrid NMH-777 and found that single adult female lays about 92-185 eggs in several egg masses in to the upper surface of leaf sheath.The incubation period ranged from 5-7 days with an average of 5.95 days. The total larval period of about 28 to 34 days with an average of 30.30 days were observed. The pupal stage lasts from 10-14 days, with an average of 12.00 days in February and March. The adult female live for 6 to 8 days while the males are about 4 to 6 days.Keywords
