The rate of infestation of linseed budfly Dasineura lini Barnes on linseed crop has been studied in rabi season 2020. Four varieties namely Jawahar-23, R552, LS-2 and local variety were selected for sowing at different time intervals. The infestation of budfly was at par in crop sowed on 1 October, 10 October, 20 October and 30 October and was significantly less than the crop sowed on 9 November and 19 November. The initiation of bud formation in crop sowed on 1, 10 and 20 October respectively was started before appearance of the pest, hence the crop was exposed to low density of the pest population and for a shorter period. In crop sowed on 30 October the initiation of bud formation coincide with appearance of the pest, while in the crop planted on 9 and 19 November bud formation started after the appearance of the pest and the crop exposed to high pest population throughout the susceptible stage of the crop
