Abstract:

The pigeonpea was infested with the number of insect pests at various stage of crop growth. Out of which the incidence pattern H. armigera of was studied. The result of the investigation pertaining to the “Screening of pigeonpea [Cajanus cajan (L.) Millsp.] against Gram pod borer, H. armigera (Hubner (Lepidoptera:Noctuide) in long duration Pigeonpea genotypes” was carried out in 2018-19 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. This insect was studied during reproductive phase of the crop during 2018-19 with the Randomized Block design. In all genotypes except AVT1-708 under trail the first incidence of gram pod borer H.armigera was observed in the 4th standard week of 2018-19. The population of pod borers in all genotypes persisted from the 4th standard week of 2018-19 to the 12th standard week of 2018-19. Maximum population of (0.69 larva/plant) in the MAL-13 (AVT1) genotype followed in the first week of 2018–19 The pooled mean population of gram pod borer was recorded highest in the genotype MAL-13 (AVT1) (check) (0.92 larva/plant) lowest in AVT1-707 (0.41 larva/plant). Pod damage caused by gram pod borer pod damage in cultivar genotype AVT2-907 ranging from 3.67 per cent to 7.67 per cent in cultivar MAL-13(AVT-1). The percentage of grain damage on various genotypes caused by Gram pod borer. The damage ranged from 0.79 per cent in the genotype AVT2-907 to 3.80 per cent in the genotype AVT1-706. The damage caused to the grain by the genotype for long-duration pigeonpea has been primarily attributed to pod fly, pod bug and gram pod borer. This ranged from 12.68% to 30.52% for pod fly, 4.71% to 8.93% for pod bug and 0.79% to 3.80% for gram pod borer.. In AVT1-708 the cereal yield of different genotypes was from 617kg / ha to 1434kg / ha with AVT1-707 genotype.
