The present investigation was carried out during rabi season (March - June) 2017 at central research farm of SHUATS, Allahabad in RBD with three replications. The ten okra genotypes viz. HRB-55, H14-A, JPM-20-16-32, IIVR-10, IC-14-934, IC-45862, JC-034-1124-A, VRO-6, 317-10-1, 326-10-1 were taken to know their response on incidence of major sucking pests viz., Aphid (Aphis gossypii), Jassid (Amrasca biguttula biguttula) and Red cotton bug (Dysdercus cingulatus). Among these ten genotypes VRO-6 showed the lowest mean population of aphid (1.57) and IIVR-10 showed the lowest mean population jassid (1.82) and red cotton bug (2.23). The highest population of all pests was recorded in genotype 317-10-1. It is observed that the population of all sucking pests reached the peak level on 22nd standard week.
