Abstract:
Sowing of nine varieties (LCK 1933, SLS 122, LSL 93, LMC 2017-R-8, JLS 95, T 397, RLC 171, RLC 175, RLC 176) was done on 11^th November, 2020 during Rabi season for investigate the seasonal incidence of linseed bud fly, Dasyneura lini (Barnes) on different varieties of linseed. Bud fly infestation started from 1^st SMW and continued up to 9^th SMW. On the basis of peak infestation period, the maximum bud fly infestation was recorded on JLS 95 (39.88%) while minimum bud fly infestation was found in LCK 1933 (30.88%) variety of linseed. The bud fly infestation percentage was ranged from 3.15% to 34.79%. The findings demonstrated that maximum and average temperature had significantly positively correlated with the bud fly infestation percentage. Minimum temperature, morning relative humidity, evening relative humidity, average relative humidity, rainfall and sunshine hours had little bearing on the bud fly infestation.
