The minimum S. litura population (0.64 larvae per plant) was observed in early date of transplanting i.e. (D1) cabbage transplanted 15 days before recommended date of transplanting. The maximum population of S. litura (2.89 larvae per plant) was noticed in late date of transplanting i.e. (D3) cabbage transplanted 15 days after recommended date of transplanting.
