ABSTRACT
An experiment on chickpea was conducted to determine the “Behavioral study of gram pod borer, Helicoverpa armigera (Lepidoptera:Noctuidae) and its management in chickpea, Cicer arietinum” during rabi season of 2021-2022 at the Organic research farm Kargunwa ji, Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (Uttar Pradesh). The population of gram pod borer, Helicoverpa armigera was monitored using pheromone trap installed in the chickpea field in variety of RVG-202. During the year the adult male moth activities were recorded in 7th standard week (early pod formation stage) to 12th standard week (pod maturity stage). The number of moth caught per day in the pheromone traps increased steadily during the early morning with a skewed distribution and a peak catch of the moth (49.6%) was observed between 05.00 h and 07.00 h, followed by a gradual decrease to dawn. This was suspended to the roof of the trap, at a height of 1.5 m. above the ground nearer to the crop canopy. Efficacy of different plant protection options viz., Neem oil @ 3 ml/lit, NPV @ 2 ml/lit, Fixing bird perches @ One perch-1, Lemon grass oil @ 7 ml/lit, Ginger and Garlic extract @ 50 ml/lit and Annona leaf extract @ 50 gm/lit were evaluated against the pest. Observations recorded on Helicoverpa armigera populations were recorded from five randomly selected plants in each plot before and after 3, 7 and 11 days of spraying. The results revealed that all treatments were significantly superior over control.
