Twenty nine long duration pigeonpea genotypes were screened for their reaction against pod fly during Kharif 2014-15 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. The first incidence of pod fly was observed in the 4th standard week in all genotypes except IVT-509, AVT-607 and AVT-605 and the population persisted up to 12th standard week in all the genotypes. The peak population of pod fly irrespective of the genotype/cultivar was recorded in 11th standard week. The mean populations of pod fly on different genotypes ranged from 0.61 pod fly maggots/ 10 pods in IVT-520 to 1.57 pod fly maggots/ 10 pods in IVT-510. The per cent pod damage due to pod fly significantly varied from 22.33 per cent in genotype IVT-520 to 46.67 per cent in genotype IVT-510. The highest grain damage by pod fly was also seen in IVT-510 (20.96%) while the lowest grain damage was observed in IVT-520 (10.67%). 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.
