Popis:	This study on the population dynamites of pod borer Helicoverpa armigera (Hubn.) on soybean revealed that it appeared from 29th Standard meteorological week (SMW) (0.40± 0.10 three leaves/ plant). It increased and reached its peak level of 2.67± 0.17/ 3 leaves/ plant during 33rd SMW. The declining trend was observed and reached 0.60± 0.13/ 3 leaves/ plant during 40th SMW. The peak infestation was 48% during 35th SMW. The incidence exhibited non-significant positive correlation with maximum (r= 0.227) and minimum temperature (r= 0.335) and evening relative humidity (RH) (r=0.315); and a significant positive one with morning RH (r= 0.599) and significant negative one with rainfall (r= -0.42). The sunshine was found to be negatively and non-significantly correlated (r = -0.069).
