The study on population dynamics of whiteflies in FCV tobacco was conducted at ICAR-CTRI, Black soil research farm, Rajahmundry during Rabi 2018-19 and 2019-20. The population dynamics of whitefly was ascertained on tobacco under prevailing weather conditions. Correlation and regression analysis of pest population was conducted with prevailing weather factors. Coefficient of determination R2 was found with a range of 4.00 to 41.56 and population of whitefly was found to be influenced up to 80 per cent by the simple and multiple regression models. Simple linear regression model revealed that morning relative humidity (RHI) had a higher impact on incidence of whitefly. In the multiple linear regression models, the impact of weather factors on the whitefly population during 2018-19 was 64.28 percent and it was 17.95 per cent during 2019-20. It can be concluded that the prevailing weather factors influences whitefly population.
