The present investigation were carried out during rabi 2013-2014 at the Entomology experimental farm of College of Agriculture JNKVV, Jabalpur to study the population dynamics of gram pod borer, Helicoverpa armigera on late sown chickpea. The pod borer egg population appeared from 3^rd SW (15/1/2014 to 21/1/2014) and was available upto the 16^th SW (16-04-2014 to 22-04-2014). Pod borer egg population attained its first peak (2.25 egg/mrl) during 12^th SW (19-03-2014 to 25-03-2014), when maximum and minimum temperature were 34 and 13.4 ^oC, respectively, whereas morning relative humidity and evening relative humidity were 79 and 27%, respectively. The pod borer larval population appeared from 4^th SW (22-1-2014 to 28-1-2014) and was available upto the 16^th SW (16-04-2014 to 22-04-2014). Pod borer larval population attained its first peak (1.15 larvae/mrl) during 7^th SW (12-02-2014 to 18-02-2014), when maximum and minimum temperature were 23.9 and 9.5 ^oC, respectively, whereas morning and evening relative humidity were 88 and 41%, respectively.
