Helicoverpa: The least larval count of Helicoverpa (1.263) was observed in the genotype  namely BP-2403 ,however, it was not significantly differ from the genotypes GT-113,GT-107 and BP-2404. The highest Helicoverpa larval count (1.590) was found in the genotypes namely BP-2406 but it was  not significantly differ from BP-2401,BP-2402 and BP-2410.

Maruca: The least larval count of Maruca (1.125) was observed in  the genotypes BP-2403 and GT-107, however , they were not significantly differ from the genotypes namely GT-113 and BP-2407. The  highest Maruca larval  count  (1.525) was found in the genotype  BP-2411 but it was not significantly differ from the genotype BP-2406.

Pod Damage Percent due to Helicoverpa: The significantly highest pod damage percent due to pod borer (29.309) was observed in the genotype BP-2407 and it was statistically atpar with the genotypesGT-103,BP-2401,BP-2402,BP-2406 and BP-2410. The least pod damage percent (19.606) was recorded in the genotype BP-2403 but it was not significantly differ from the genotypes GT-107,BP-2404,BP-2405,BP-2408,BP-2409 and BP-2411.

 Pod Damage Percent due to Maruca: The highest pod damage percent due to pod borer (24.984) was observed in the genotype BP-2411 and it was it was statistically at par with the genotypes BP-2405,BP-2406 and BP-2409. The least pod damage percent (14.892)was recorded in the genotype namely GT-107,however, it was not significantly differ from the genotypes GT-113,BP-2405,BP-2406 and BP-2409.

Pod flies: The least pod fly maggot/pupa count (2.825) was observed in the genotype BP-2408 and it was statistically at par with the genotypes BP-2402,BP-2403 and BP-2404. The significantly highest maggot count of pod fly (4.080) was observed in the genotype GT-107 and it was  statistically at par with the genotypes GT-113,BP-2406,BP-2410 and BP-2411. The least pod damage percent due to pod fly (15.172) was found in the genotype BP-2408,however, it was not significantly differ from the genotypes BP-2402,BP-2403 and BP-2404. The  highest pod damage percent (25.330) was observed in GT-107 and it was  statistically at par with  the genotypes GT-113,BP-2410 and BP-2411.    

The genotypes namely BP-2403,BP-2404 and GT-107 were consider as tolerant while genotypes namely BP-2406 and BP-2410 were found susceptible  against pod borers.

The genotypes namely BP-2408,BP-2402,BP-2404 and BP-2403 were found to be tolerant where as the genotypes namely BP-2410 and BP-2411 were found susceptible against podfly attack.
