Abstract: The present investigation was Okra leafhopper, Amrasca biguttula biguttula (Ishida) and whitefly, Bemisia tabaci (Gennadius) on okra was carried out at Central Research Field, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, (U.P.), India. This research was conducted for during kharif season (July to December) 2016. The leafhopper/ whitefly was noticed when the crop was in vegetative stage. The data presented in revealed that the infestation of leafhopper/whitefly on okra commenced in the 35th SMW (august last week) (0.8)/ (1.2) i.e. four weeks after sowing which gradually increased and reached to peak (12.40)/ (11.53) in the 42nd SMW (October third week) 35.050C and 25.70C maximum and minimum temperatures, 89.7% and 51.8% morning and evening relative humidity and 00.0 mm rainfall. That showed significant positive correlation with sunshine (r= 0.54)/(r= 0.61) while remaining abiotic factors showed non-significant effect. As soon as the fruiting started, the incidence of the insect pest started to decline and disappeared during 48th SMW (November last week).
