Seasonal incidence studies of Helicoverpa armigera (Hubner) infesting chickpea were undertaken during 2016-17 at Instructional farm, Department of Agronomy, College of Agriculture, J.A.U, Junagadh. A dominant invertebrate animal, insect, have capacity to change their behavior and habitat with the changing of the environment and so, it is necessary to see the impact of changing pattern in abiotic factors on H. armigera on chickpea so seasonal incidence with provide information regarding this utility. The result showed that population of H. armigera showed highly significant negative correlation with maximum temperature (r = -0.739) and highly significant negative correlation with minimum temperature (r = -0.725). Pest showed highly significant positive correlation with morning relative humidity (r = 0.695) and also highly significant positive correlation with evening relative humidity (r = 0.743). Result showed that larval population of H. armigera has non-significant negative correlation with mean bright sunshine hours (r = -0.442) and also has non-significant positive correlation with wind velocity (r = 0.189).
