Abstract: One (T1) and two (T2) light traps per ha were compared with control with no light source (T3) against gram pod borer, Helicoverpa armigera. Pooled data of 2018 and 2019Â showed that TI resulted with average population of 0.31larvae per plant with 5.46% pod damage and average yield of 1235 kg per ha. In T2, lowest larval population was recorded (0.25/plant), lesser pod damage (4.02%) and higher yield (1244.8 kg /ha) while in control plots (T3), larval population density was maximum with 0.377 larvae/plant with pod damage of 10-25% and 1162.90 kg /ha yield was recorded.
