摘　　要：将Q型烟粉虱种群按其生长发育顺序划分为卵、低龄若虫、高龄若虫、成虫4个阶段,把各阶段的作用因子划分为相对独立的状态。通过对Q型烟粉虱自然种群数量的调查和对实验种群数量的观察,对实验种群的自然种群生命表进行了研究。研究表明,Q型烟粉虱的自然种群趋势指数(I)为28.22,说明下一代种群数量将为当代种群数量的28.22倍,世代总成活率为11%。The populations of Bemisia tabaci biotype Q can be divided into four stages including eggs,young nymphs,senile nymphs and adults according to the growth and development process,and the factors of each stage were divided independently. Based on the field surveys on natural populations and laboratory observation on experimental populations of Bemisia tabaci biotype Q,the natural population life table of Bemisia tabaci biotype Q in tobacco was investigated. The results showed that the trend index（ I） of natural population of Bemisia tabaci biotype Q was 28. 22,indicating that the population of next generation would be 28. 22 times of the contemporary population,and the general survival rate was 11%.
