The investigation on "Seasonal incidence of Helicoverpa armigera (Hub.) on chickpea in relation to abiotic factors semi-arid region of Rajasthan" were conducted at Agronomy Farm, S.K.N. College of Agriculture, Jobner, Rajasthan during two consecutive season i.e. Rabi, 2022-23 and 2023-24. During the investigation the incidence of gram pod borer, H. armigera in chickpea crop started from first and second week of December and reached to peak at second to third week of February, respectively during both year of study. The larval population of H. armigera had significant positive correlation with maximum and minimum temperatures and significant negative correlation with morning relative humidity.
