An investigation on “Seasonal incidence, of pod borer complex in black gram” was carried out at Pulses Research Station, Junagadh Agricultural University, Junagadh and Main Sugarcane Research Station, Junagadh Agricultural University, Kodinar. Seasonal abundance of Helicoverpa armigera Hubner in black gram during 2024 showed that the pest activity commenced from the 3^rd week after germination i.e., 4^th week of September (39^th SMW) and continued till the 13^th week after germination i.e., the fourth week of November (48^th SMW) which ranged from 0.40 to 2.60 larvae/plant. After the appearance of H. armigera (0.40 larvae/plant) in 3^rd week after germination i.e., 4^th week of September (39^th SMW), it was increased in 4^th week after germination i.e., 1^st week of October (40^th SMW). After 1^st week of October, the population increased continuously upto 1^st week of November (45^th SMW) and also reached a peak level up to 2.60 larvae/plant. The correlation analysis between weather parameters and larval population highly significant positive relationship was established between larval population of H. armigera (0.848**) and M. vitrata (0.671**) with maximum temperature. While a negative relation between larval population (H. armigera) and relative humidity (-0.029) and rainfall (-0.075). Larval population (M. vitrata) also find negative relation with relative humidity (-0.184) and rainfall (-0.129).
