Monitoring of Gram Pod Borer, Helicoverpa armigera through Pheromone Trap in Chickpea, Cicer arietinum L Crop and their Influence with Abiotic Parameters

Abstract— The present research experiments were carried out during Rabi season of the year 2022-23 at the Agricultural Research Farm of Baba Raghav Das Post Graduate College, Deoria (UP) to monitor the population of Helicoverpa armigera by using pheromone traps in chickpea (variety-‘Pusa-261’). The male moth catches of H. armigera was recorded from 4th SMW (1.5 moths/trap/week) and the moths catches increased in subsequent weeks and reached at peak during 6th, 7th and 8th SMW with 4 moths/trap/week, 3.5 moths/trap/week and 4 moths/trap/week, respectively, between 2nd week of February to 4th week of February, at vegetative to reproductive stage of crop. Abiotic factors such as rainfall, maximum and minimum temperatures showed a non-significant negative correlation with male moth catches of Helicoverpa armigera, while maximum and minimum relative humidity exhibited a positive correlation. However, all the weathers parameters together influenced the H. armigera male moth’s catches in the chickpea up to extent of 75.93%.
