Twenty nine long duration pigeonpea genotypes were screened for their reaction against pod bug during Kharif 2014-15 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. The first incidence of pod bug was observed in the 4th standard week in all the genotypes and the population persisted up to 12th standard week in all the genotypes. The peak population of pod bug was found in all genotypes during 12th standard week except IVT-512, IVT-501, IVT-504, IVT-516 where the peak was recorded during 11th standard week. The mean populations of pod bug on different genotypes ranged from 1.57 bugs/ plant in IVT-520 to 3.91 bugs/ plant in IVT-510. The per cent pod damage due to pod bug significantly varied from 16.33 per cent in genotype IVT-520 to 37.33 per cent in genotype IVT-510. The highest grain damage by pod bug was also seen in IVT-510 (20.75%) while the lowest grain damage was observed in IVT-520 (6.98%). The grain yield of different genotypes also differed significantly and ranged from 479 kg/ha in the genotype IVT-510 to 3314 kg/ha in IVT-520.
