Abstract: An investigation to study the population dynamics of leafhopper, Amrasca biguttula biguttula (Ishida) (Cicadellidae) in okra was carried out at CPCA Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat during summer 2023. The incidence of leafhopper commenced after one week after germination (10^th SMW) and continued up to removal of crop in the 21^th SMW. A higher incidence of leafhopper was observed during the 17^th to 20^th SMW. Leafhopper population exhibited significant positive correlation with maximum temperature, whereas it showed highly significant positive correlation with minimum temperature, bright sunshine hours and evaporation. Population of coccinellids and spider had highly significant positive correlation with leafhopper population.
