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 (25.46± 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.
