abstract
In this study, the field trial was conducted to determine the population dynamics, at the Central field, Department of Entomology SHUATS, Allahabad during kharif 2016. The whitefly was noticed when the crop was in vegetative stage. The infestation of whitefly on okra commenced from August 4^th week (35^th SMW) 1.40 whiteflies/3leaves, which gradually increased and reached to its peak 12.53 whiteflies/ 3leaves in the October 3^rd week (42^nd SMW) at 35.05⁰C and 25.70⁰C maximum and minimum temperatures, 89.70% and 51.80% morning and evening relative humidity and 00.00 mm rainfall. As soon as the fruiting started, the incidence of this insect pest started to decline and disappeared during November 4^th week (48^th SMW). That showed significant positive correlation with Sunshine (r= 0.601) while remaining abiotic factors showed non-significant effect.
