| 摘 要： | 通过组建福州地区９～１０月份的小菜蛾自然种群生命表，表明影响小菜蛾自然种群生命表数量的重要因子是捕食与其他，其控制指数为２．８１２５；其次为寄生，控制指数为２．３１８１；而病亡的控制指数为１．２１４１．种群趋势指数Ｉ值为２．８３３．

| Abstract: | The natural population life table of diamondback moth (DBM), Plutella xylostella (L.) in Fuzhou in September and October was constructed, which indicated that the most important factor influencing the natural population of DBM was predation and others and its index of population control (IPC) was 2.8125; the second was parasitism at the stages of larva and pupa and its IPC was 2.3181; the IPC of disease was 1.2141. The population trend index of DBM was 2.833. |
