Biology of Pieris brassicae (L.) was studied on cauliflower under screen house conditions on main and late season crops during 2021-22 in PAU, Ludhiana, Punjab. The total lifecycle was maximum for both male (50.11± 1.30) and female (52.24± 1.27) in the main season crop and minimum in the late season crop. Survival was maximum (27.67± 0.04%) in main season crop than (25.4± 0.06) in late season crop due to colder climatic conditions. The maximum growth index was observed in late season crop (1.54± 0.14) as compared to main season crop (1.13± 0.09) which indicated that P. brassicae developed better on late season crops.
