Abstract: The present study was conducted at the Research cum Instructional Farm, IGKV, Raipur, Chhattisgarh during Kharif season 2013-2014. The bioefficacy of eight newer insecticidal molecules, acetamiprid 20SP, indoxacarb 14.5SC, acephate 75SP, spinosad 45SC, emamectin benzoate 5WSG, flubendiamide 20WG, rynaxipyr 18.5SC and thiamethoxam 25WG each at two doses against tur pod borer (plume moth) infesting pigeonpea were evaluated under field conditions including untreated control as check. The percent pod and grain damage ranged from 5.06 & 1.56 to 8.37 & 4.03. Management of pod borer by newer insecticides, Spinosad maintained its lethal effect as least pod damage of 5.06 %, followed by emamectin benzoate with pod damage of 6.02%. The least grain damage 1.56% was recorded with spinosad and highest grain damage 4.03% was recorded with flubendiamide. Of all the tested insecticides the highest grain yield 1360.54 Kg/ha was recorded with spinosad and lowest yield 1037.41Kg/ha was recorded with flubendiamide. In the check (control), the yield obtained was 816.32 Kg/ha which was least of all the insecticides tested.
