Abstract: A experiments on “Management of whitefly, Bemisia tabaci (Gennadius) in Tomato, (Solanum lycopersicum Mill)” was conducted at College of Agriculture, Bikaner during Rabi 2017-18. The seasonal incidence of white fly on tomato and correlation with abiotic factors during Rabi 2017-18. The incidence of whitefly on tomato started, when there was 20.50C maximum and 7.10C minimum temperature, 81.3 and 46.1 per cent maximum and minimum relative humidity, respectively with no rainfall. The maximum infestation (15.00 whiteflies/3 leaves) was observed at 35.0 0C maximum, 16.9 0C minimum temperature, whereas, 55.6 per cent maximum and 17.7 per cent minimum relative humidities with 0.8 mm rainfall during the study period. A significant positive correlation was recorded between pest population and maximum(r=0.565) and minimum(r=0.526) temperature, whereas, it was non-significant negative with maximum relative humidity (r= -0.430) and a significant negative correlation with minimum relative humidity(r= -0.525). A non- significant negative correlation was computed between pest population and total rainfall (r= -0.087).
