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 YSBtab 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 YSBTab containing (Z)-11 hexadecinal and (Z)- 9 hexadecinal at 3:1 ratio was used. This experiment, resulted that the two peaks were found (27th August and 1st October) during rainy season. The Exosex YSBTab @ 20 mg had significantly exhibited minimum oviposition by female as well as significantly managed the yellow stem borer as compared to other pheromone treatments.
