The field experiment was conducted at Horticulture Research Scheme (Vegetable) VNMKV, Parbhani of during Rabi, 2017-18 and Summer 2018-19. The epidemiological studies viz., yield losses, vector population dynamics and disease incidence were recorded during the course of investigation. The tomato leaf curl virus disease of tomato has been found to cause heavy yield losses i.e. 96.80 and 98.43 in both Rabi and Summer season, respectively. However, the outbreak was not uniform throughout season. In Rabi season whitefly population and disease incidence was higher i.e. 2.06/ leaf and 25.94 per cent, respectively, whereas in Summer season whitefly population and disease incidence was 5.13/ leaf and 31.08 per cent, respectively. The whitefly population and disease incidence was relatively more in Summer than Rabi transplanting crop. A strong positive correlation was obtained between vector population dynamics and disease incidence in tomato plants.
