Abstract: Biological control becomes more and more important in the process of pest management. As an important part of biological control, the evaluation of pest controlling is also indispensable. Life tables are one of the most useful tools in the study of insect population dynamics and play the vital role in biology and ecology researches. With continual developing and extending, life tables in formation and the analytical methods are gradually improved to be widespread in evaluation of pest control by natural enemies, insect resistance and biological pesticide. Although there are some shortages, life tables are not only to be used for summarizing the effect and the quantitative evaluation, but also to increase the ways of estimating the population growth trend to select the optimum pest management solutions.
