Tomato (Solanum lycopersicum) is a major vegetable crop globally, but its productivity is significantly affected by key insect pests such as whiteflies (Bemisiatabaci), jassids (Amrascabiguttulabiguttula) and fruit borer (Helicoverpa armigera). The limitations of conventional insecticidesparticularly resistance development, environmental concerns, and non-target effectshave necessitated the evaluation of newer, more selective molecules. This study assessed the efficacy of seven modern insecticides: Chlorantraniliprole 18.5% SC, Flubendiamide 39.5% SC, Emamectin benzoate 5% SG, Spinosad 45% SC, Indoxacarb 14.5% SC, Abamectin 1.9% EC, and Lambda-cyhalothrin 5% EC against major tomato pests. Field experiments were conducted during the Kharif 2019–20 using a randomized block design with three replications. Pest populations were recorded before spraying and at 1, 3, 7, and 10 days after application, while fruit borer infestation was assessed through damaged fruit counts.

Results revealed that all insecticides significantly reduced pest populations compared to the untreated control. Spinosad 45 SC consistently demonstrated the highest efficacy against whiteflies and jassids, followed by abamectin. For fruit borer management, chlorantraniliprole 18.5 SC was most effective, reducing infestation to approximately 11.6%, followed by flubendiamide and emamectin benzoate. Indoxacarb showed comparatively lower performance against sucking pests.
