The present investigation was carried out to study the “Eco friendly management of yellow stem borer, Scirpophaga incertulas (Walker) on paddy in western plain zone of Uttar Pradesh” in randomized block design with three replications and seven treatments at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The yellow stem borer, S. incertulas (Walker) was recorded as major pest. The incidence of S. incertulas (Walker) was recorded on the incidence of yellow stem borer Scirpophaga incertulas (Walker) showed that it was recorded on 26th standard week for the first time and continued till second week of November i.e. 46th standard week. The infestation of stem borer recorded as dead heart/ white ear head ranged from 0.85 to 15.25 per cent during the crop season i.e. Kharif 2017 and positive correlated with all the other weather parameters.

The present investigation was carried out to study the efficacy of different novel insecticides and bio-pesticides against stem borer Scirpophaga incertulus (Walker) during kharif 2015-16 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Efficacy of newer insecticides (fipronil 5 SC, cartap hydrochloride 50SP,chlorpyriphos 20 EC, imidacloprid), one biopesticide (Neemarin 1500 ppm) and one bio-control agent (Trichogramma japonicum) were evaluated against yellow stem borer Scirpophaga incertulas (Walk.) in Basmati rice. The stem borer recorded as dead heart ear heads ranged from 4.85 to 10.55 per cent and white ear head showed that it was recorded on 38th standard weak. All the treatments were found significantly effective in reducing the infestation of stem borer and increasing the yield compared with control. Application of fipronil 5 SC was the most effective treatment in reducing the stem borer infestation at all observational interval resulting highest grain yield The results of paddy yield depicted in table 3, showed that the plots treated with fipronil 0.3 GR @ 25 kg/ha gave the highest yield (45.56 q/ha).

Natural Parasitism

Three species of parasitoids viz., Telenomus dignus Gahan, Trichogramma japonicum, Ishii and Tetrastichus schoenobii Ferriere were recorded from the egg masses of rice yellow stem borer, Scirpophaga incertulas (Walker) in a field study. The extent of parasitism was high during Rabi (43.33 – 93.33 %) and low during Kharif (0 - 40.00 %). Parasitism by T. dignus was maximum in October (50.00 %), T. japonicum, in November (23.08 %) and T. schoenobii in February (55.55 %). dignus and T. schoenobii in combination parasitized maximum number of egg masses (41.82 %). Multiple parasitism by the three species was high in December (8.33 %) and January (7.14%). Parasitic potential was maximum, when T. schoenobii alone parasitised the egg masses followed by T. dignus and T. schoenobii in combination. Host density in the field influenced the extent of parasitism.
