The studies on plant morphological and anatomical characters in okra showed that shoot of varieties less susceptible to okra shoot and fruit borer Earias spp. had more lignified tissues with compact vascular bundles and narrow shoot pith. Significant negative correlation was found between silica content and degree of shoot damage. The fruit borer preferred the dark green coloured fruits less. The varieties having medium long, less smooth, more trichomes and minimum seeded fruits were less infested. The biochemical characters such as total sugar and crude protein were positively correlated with fruit borer infestation, whereas, total phenols had negative correlation.
