  • This paper deals with the life tables and the effects of different population density on the survival rate,the developmental rate and the ovipositional rate of the 2nd and 3rd generational xeperimental populations of Diaphania indica (saunders).The results indicated that:(1)the intrinsic rates of increase (rm) of its 2nd and 3rd generational experimental populational are 0.0792 and 0.0487,respectively.(2)its accumulated ovipositional rates hold S-type change forms as the ovipositional time.(3)the larval developmental rate,the larval survival rate and the adult ovipositional rate drop as the population density is increased.
