However, description regarding different biological stages and information about performance parameters of P. are to survey fields design effective management. In this study, wild population was adapted on white cabbage then cauliflower, broccoli leaves were tested under laboratory conditions at 20±2°C, 50% relative humidity 16:8 (L:D) photoperiod. The development times 23.41±0.38 days cabbage, 25.12±0.56 cauliflower 26.05±0.56 leaves. generation 25.03±0.42 29.99±1.49 30.47±1.04 eggs laid individually or shape small groups host There 4 instars based molting head capsule diameters all hosts. durations larval stages, number eggs, sex differentiation fitness determined plants.
