Tomato ( Solanum lycopersicum L.) is one of the most important Solanaceous and remunerative vegetable crops. However, despite its value in fresh and processing markets, many farmers are concerned about pest resistance. Therefore, looking to the seriousness of pest menace particularly leaf curl and fruit borer, research is needed to reduce the chemical pressure and establish an ecological equilibrium in tomato fields. A combination of bio‐intensive pest management (BIPM) and chemo‐intensive pest management (CIPM) were followed trap crop marigold ( Tagetes erecta L.) and yellow sticky traps to manage these pests during 2016–2017 and 2017–2018. The percent plant infestation with leaf curl (0.6–0.9) and fruit infestation with fruit borer (5.2–6.7) were observed in BIPM and CIPM. In these fields, the application of insecticides increased yields 30–38.3%. There was 47.1–56.8% higher net return in BIPM and 59.5–68.9% higher in CIPM than farmers’ practices. Similarly, benefit cost ratio was analyzed 2.5:3.6 in BIPM and 2.5:3.7 in CIPM.
