Abstract

The present study entitled “Evaluation of pheromone traps for the management of pod borer, Helicoverpa armigera (Hubner) in Redgram [Cajanus cajan (L.) Millsp.] ecosystem” was carried out to study the influence of trap height on catches of H. armigera in redgram ecosystem during kharif 2017 at experimental farm of NPRC, Vamban and farmer’s field at Vadakaddu.Funnel traps were more effective compared to delta traps and green funnel traps placed at the level of crop canopy (96.0 moths / 5 traps) and one foot below the crop canopy (94.8 moths / 5 traps) performed well compared to traps placed at two feet below the crop canopy (77.1 moths / 5 traps), one foot above the crop canopy (66.6 moths / 5 traps) and two feet above the crop canopy (58.9 moths / 5 traps).
