Fertilization plays an important role in plant quality and can affect the biology characters of herbivorous insects indirectly. Tobacco planting was usually guided by appointed government organizations in China. A special compound fertilizer (N?P2O5?K2O is 1?1.2?2.5 in ratio) was recommended to use in many tobacco planting area. An experiment with treatments of five different fertilization levels (75(A), 90(B), 105(C), 120(D) and 135(E) kg/hm2) was carried out to assess the nutritive qualities in tobacco leaves and influencing of development, nutritional indices and fecundity on the Spodoptera litura when reared on them. The results indicated that the S. lituralarvae grew faster, and had longer female longevity and greater fecundity when reared on the tobacco leaves in fertilization level group C than those fed on the leave..
