The field trial was conducted at Central Research Field, Department of Entomology, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during kharif season 2023.The experiment was laid out in in Randomised Block Design (RBD) with eight treatments each replicated thrice using variety Kashi Chaman. The treatments viz., T₁ Beauveria bassiana 1.5% T₂ Spinosad 45%SC T₃ Neem seed kernel extract 10%WP T₄ Emamectin Benzoate 5SG T₅ Fipronil 5SC T₆ Chlorantraniliprole 18.5SC T₇ Azadirachtin 0.03%WSP 300PPM (5ml/lit) and along with untreated control T₀ against Earias vittella in okra. The data on percentage of shoot and fruit infestation of okra shoot and fruit borer first and second spray mean revealed that all treatments are significantly superior over control. Among all the treatments lowest per cent shoot and fruit, infestation was recorded in T₆ Chlorantraniliprole 18.5SC (8.46) (9.44),, T₂ Spinosad 45% SC (9.95) (10.44),, T₄ Emamectin benzoate 5%SG (11.83) (11.85),, T₅ Fipronil 5%SC (12.96) (12.91),, T₃ Neem seed kernel extract 10% WP (14.82) (13.27), T₁ Beauveria bassiana 1.5% (15.94) (14.62) and T₇ Azadirachtin 0.03%WSP 300PPM (5ml/lit) (16.97) (14.79) and is significantly superior over the control (23.78) (23.26). While The highest yield was recorded in T₆ Chlorantraniliprole 18.5SC (210.2q/ha),as well as B:C ratio (1:6.54),  T₂ Spinosad 45%SC (195.7q/ha) (1:6.02),, T₄ Emamectin benzoate 5SG (163.4q/ha) (1:5.17), T₅ Fipronil 5SC(149.2q/ha) (1:4.69), T₃  Neem seed kernel extract10%WP (138.4q/ha) (1:4.42),, T₁ Beauveria bassiana 1.5% (131.7q/ha) (1:4.00), T₇  Azadirachtin 0.03%WSP 300PPM (5ml/lit) (120.2q/ha) (1:3.71), as compared to T₀ control (90.2q/ha) (1:2.96).
