Tomato (Lycopersicon esculentum), a member of the Solanaceae family, is a widely cultivated crop in tropical and subtropical regions, particularly in India, where it holds significant economic value. This crop is vulnerable to various insect pests, including Fruit borer (Helicoverpa armigera), Whitefly (Bemisia tabaci), Jassid (Amrasca biguttula biguttula), and aphid (Aphis gossypii). These pests contribute to severe losses in both quality and quantity, with fruit borer being particularly destructive, causing yield reductions of up to 70%. The present study examines the seasonal incidence of major insect pests on tomato and their correlation with climatic parameters to devise effective pest management strategies. Conducted during the Kharif season of 2019-2020 in Madhya Pradesh, India, the study involved monitoring pest populations at weekly intervals and analysing correlations with weather variables such as temperature, humidity, wind speed, sunshine, and rainfall.
