| Abstract: | In 1998～1999, the natural population life table of pantana phyllostachysae Chao was studied in Xiqin village, Nanping city, Fujian Province. Based on the investigation data, the natural population life table of overwinter generation and the average life table in five generations were developed. It was concluded that all the survival curves from the life tables belong to Price's type A, the trend index of the average natural population was 1.658, and that of the overwinter population was 1.872. The death of larvae in 1～2 instar was the key factor affecting population dynamics, and natural enemies were the key factor between 4th instar larvae and pupae stage. |
