An experiment was conducted to observe the studies on the major insect pests of okra during Kharif season of 2011 at Department Of Entomology, Live Stock Farm, Adhartal, J.N.K.V.V. Jabalpur (M.P.). Jassids and whitefly incidence was observed from 27 DAS (16 September 2011) to 90 DAS (18 November 2011) with one distinct peak, respectively during 44 SMW withmean population (nymph + adult) per 30 leaf was 26.11 for jassids and 25.6 for whitefly. While initation of fruit infestation by shoot and fruit borer recorded at 41% SMW (01-07 Oct 2011) and epidemic at 41SMW (08-14 Oct. 2011) with 35.35 per cent.
