通过采用林间系统调查，平均历期法，组建得到湿地松粉蚧自然种群连续世代生命表，结果表明：越冬代初龄若虫期至第一代初龄若虫早期时的种群趋势指数Ｉ值为５．７０，完整第一代结束时间的Ｉ值为０．９２，表明下代种群数量将为当代种群数量的５．７０和０．９２倍；在新侵入区，没有发现寄生性天敌，捕食性天敌的排除作用控制指数ＥＩＰＣ为１．２６，表明捕食性天敌对该粉蚧的控制作用不明显；“其它”类因子是影响种群数量发展趋势的重要因子，其ＥＩＰＣ值为８３．６８。
By using the forest system survey and the average duration method, the life table of the natural populations of mealybugs wetlands was established. The results showed that the population trend index I in the early stage of overwintering from early nymph to first instar nymphs was 5.70, and the I value of the complete first generation ending time was 0.92, indicating that the number of the next generation population will be 5.70 and 0.92 times the number of the contemporary population. In the new invasion area, no parasitic natural enemies were found, The control index EIPC of sexual enemies was 1.26, indicating that the control effect of predatory natural enemies on this mealybug was insignificant. The “other” factors were the important factors influencing the population development trend, and the EIPC value was 83.68.
