Six insecticides and Heir eight combinations were tested for their efficacy against brinjal fruit and shoot borer, Leucinodes orbonalis. Endosulfan + deltamethrin (0.07%, 0.0025%) and endosulfan + fenvalerate (0.07% + 0.005%) were highly effective against fruit borer that recorded only 13.3% damage as compared to 69.8% in control. The other promising treatments which significantly reduced the fruit damage over the control were in the order: carbaryl + fenvalerate = dichlorvos + fenvalerate (14.9%) > malathion + fenvalerate (16.4%) > fenvalerate + deltamethrin (16.6%) > dichlorvos = carbaryl + deltamethrin = malathion = dichorvos + deltamethrin = malathion + deltamethrin (18.3%) > endosulfan (20.0%) > carbaryl (21.6%) with mean percentage of damage 14.9, 16.4, 18.3, 20.0, 21.6 and 69.8%, respectively. Carbaryl was least effective, but its combinations with pyrethroids were proved superior over carbaryl alone. Cost - benefit ratio ranged from a minimum of 1: 5.10 (carbaryl) to a maximum of 1: 20.44 (fenvalerate). Dichlorvos + fenvalerate combination gave the highest yield of 263.45 q/ha, whereas carbaryl was least effective giving 225.7 q/ha. with a net gain of Rupees 42,443.00 (US$ 886.00) and 28,141.00 (US$ 587.49), respectively. The other treatments were intermediate between the two insecticide regimes. However, all the treatments were superior over the control which produced 113.58 q/ha with a net gain of Rupees 340.00 only.
