Yellow stem borer Scirpophaga insertulas (Walker) devastated the rice crop in both vegetative and reproductive growth stages during monsoon and summer seasons of West Bengal. A field trial was conducted for evaluating the efficacy of pheromone lure against rice yellow stem borer in farmers’ fields under Gopalpur co-operative society, Burdwan during rainy 2011-2013. The field trials consisted of six treatments including control viz. T₁= 50 pheromone traps/ha installed at 10 DAT where lure was not replaced, T₂= 50 pheromone traps/ha installed at 10 DAT and lure replaced at 45 DAT, T₃= 50 pheromone traps/ha installed at 10 DAT and lure replaced at 45 and 60 DAT, T₄= 80 Exosex YSB_tab  per hectare @ 20 mg installed at 15 DAT, T₅= as per farmers practice where cartap hydrochloride @ 750 g a.i/ha used at 45 and 60 DAT and T₆= untreated control. Here both the dispenser (lure) and Exosex YSB_Tab containing (Z)-11 hexadecinal and (Z)-9 hexadecinal at 3:1 ratio was used. This experiment, resulted that the two peaks were found (27^th August and 1^st October) during rainy season. The Exosex YSB_Tab @ 20 mg had significantly exhibited minimum oviposition by female as well as significantly managed the yellow stem borer as compared to other pheromone treatments.
