The experiment was conducted in the Student’s Instructional farm of NDUAT, Faizabad during Kharif, 2012 and 2013 to evaluate the effects of various biophysical plant characters on twenty four okra germplasm against shoot and fruit borer, Earias spp. The results indicated that all the tested germplasm were significantly differed in relation to shoot and fruit borer population at shoot and fruit stages of the crop. The minimum fruits infestation was recorded on Arka Anamika germplasm (8.75 and 11.55%) followed by NDO 67 (10.36 and 13.76%) and the maximum was on Pusa Sawani (33.70 and 39.52%) followed by VRO 6 (30.74 and 36.50%) during the Kharif, 2012 and 2013, respectively. The plant height exhibited positive correlation (r = 0.160, 0.178) and (r =0.123, 0.249) with shoot and fruit infestation, however, negative correlation were observed between number of branches/plant, fruit length, number of fruits/plant, fruit weight and yield during Kharif, 2012 and 2013, respectively. The morphological attributes showed no significant correlation between shoot and fruit damage on okra. Plant height, fruit length, diameter and color of the cultivars had no significant effect on the infestation of Earias spp.
