Abstract
Studies on the population dynamics of Helicoverpa armigera (Hubner) on chickpea crop conducted at Pantnagar during 2009-10 and 2010-11 revealed that the infestation of the pest started in the second fortnight of December and attained its peak in the first week of April and last week of March during 2009-10 and 2010-11, respectively. The larval population of the pest occurred throughout the growth period of crop with maximum at pod and grain formation stages. Maximum and minimum temperatures, sunshine hours and wind speed showed significant positive correlation with larval population whereas relative humidity and rainfall exhibited negative impact on larval population
