Abstract: An experiment was conducted at Agriculture entomology research farm, College of Agriculture, RVSKVV, Gwalior, Madhya Pradesh during kharif season 2015-16 and 2016-17 taken to know the infestation of okra shoot and fruit borer, Earias vittella (Fab.) on okra. Sixteen okra genotypes viz., 326-10-1, 633-7-1, IC – 140206, IC – 282280, 303- 10- 1, 461-10-1, IC- 43742, 419-10-1, 599-8-1, IPM-20-16-39, 1753, IC- 288892, 304-10-1, 100-10-1, 231- 10-1 and VRO-22 were screened to know their response on the basis of fruit damage scale. Only two genotypes viz., IC – 282280 and 303- 10- 1 showed tolerant, remained genotypes were falled in the category of moderately resistance, However, the IPM-20-16-39 showed minimum fruit damage with highest yield 32.29 q/ha, while, IC – 282280 genotype showed highest no. of fruit damage and fruit weight damage and it exhibited lowest health fruit yield 16.77 q/ha was noticed during 2015-16 and 2016-17. The peak borer infestation (24.50%) was recorded during fourth week of September.
