Abstract: Tomatoes are an important produce in the Solanaceae family, and their productivity is heavily influenced by insect pests. Pesticide application is a common approach of pest management in Nepal’s local and large-scale vegetable farms. A field experiment was conducted using seven treatments, namely: T1 (Metarhizium anisopiliae at 2 g/liter), T2 (Neembicide at 5 ml/liter), T3 (Jholmol at 1:4 (Jholmol: water), T4 (Imidacloprid at 0.3 ml/liter), T5 (Control), T6 (Emamectin benzoate at 2 g/liter), and T7 (Chlorantraniliprole at 0.3 ml/liter) to control Tomato leaf miner. In a Randomized Complete Block Design (RCBD), these treatments were replicated three times in the field of Gokuleshwor Agriculture and Animal Science College in Gokuleshwor, Baitadi. The effect of different treatments on the population of Tomato leaf miner was studied using the number of infested leaves per plant, the number of live larva per plant (leaves and buds), and the number of infested terminal buds per plant from four plants forsaking the corner plants in each plot. The study findings revealed that the Control had the maximum number of live larvae per plant as well as the lowest damage in Emamectin benzoate (0.16 per plant), followed by Chlorantraniliprole (0.33 per plant) and Neembicide (0.42 per plant). The highest number of infested leaves per plant was recorded in Control (3.25 per plant) and the lowest in Chlorantraniliprole (1.66 per plant), followed by Emamectin benzoate (1.86 per plant) and Neembicide (2.08 per plant). The number of infested terminal buds per plant was recorded as highest in Control (0.58 per plant) and lowest in Chlorantraniliprole (0.08 per plant), followed by Imidacloprid (0.25 per plant) and Emamectin benzoate (0.33 per plant). So for the management of tomato leaf miners, the insecticides Chlorantraniliprole and Emamectin benzoate would be the best alternatives.
