(Ag) Entomology Department: Entomology Name of Advisor: Dr. Hem Singh Thesis Title: “Studies on seasonal incidence and eco-friendly management of yellow stem borer, Scirpophaga incertulas (Walker) in Basmati rice” The present investigation entitled “Studies on seasonal incidence and eco- friendly management of yellow stem borer, Scirpophaga incertulas (Walker) in Basmati rice” was carried out at Crop Research Centre, Chirori, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut during Kharif, 2022. The incidence of yellow stem borer recorded as dead hearts and white ear heads ranged from 2.43 to 6.55 per cent. The incidence of yellow stem borer was reached highest (6.55 per cent dead hearts) during 37th standard week. The highest white ear heads infestation was 6 per cent recorded during 42th standard week. The incidence of yellow stem borer was a non-significant positive correlation with maximum temperature (r = 0.105), evening relative humidity (r = 0.411) and non-significant negative correlation with minimum temperature (r = -0.003), morning relative humidity (r = -0.242) and rainfall (r = - 0.155). During the Kharif 2022, Cartap hydrochloride 4 % G @ 20 kg/ha recorded the lowest infestation at 7th, 14th and 21st days after first application of treatments during Kharif, 2022. Eucalyptus oil @ 1 litre/ha was found to be the least effective treatment in comparison to others treatments. The highest yield was recorded from the plots treated with Cartap hydrochloride 4 % G @ 20 kg/ha which was recorded 46.5 q/ha yield during Kharif, 2022. The lowest yield was observed from the plots treated with Eucalyptus oil @ 1 litre/ha (40.8 q/ha). As far as incremental cost-benefit ratio is concerned the highest incremental cost benefit ratio was found with Cartap hydrochloride 4 % G @ 20 kg/ha (1: 5.69) treated plots while the least incremental cost benefit ratio was found with Eucalyptus oil @ 1 litre/ha (1: 0.06) treated plots.
