Abstract

The population dynamics of gram pod borer Helicoverpa armigera (Hubner) on chickpea was evaluated at the Agricultural Research Farm of B R D P G College, Deoria, Uttar Pradesh during rabi 2022-23. The larval incidence was initially recorded in 6th SMW (first week of February) (2.3 larvae/ plant) with a peak in 11th SMW (third week of March) (10.53 larvae/ plant). Larval incidence on chickpea variety Pusa-261 showed significant positive correlation with maximum temperature (0.837) and minimum temperature (0.804), whereas relative humidity (maximum and minimum) revealed non-significant negative correlation (-0.410), (-0.588), respectively. Correlation between rainfall and larval incidence was found positive and significant (0.734). However, all the weather parameters together contributed 94.18% towards larval incidence.
