| 摘 要： | 利用Berryman法组建松突圆蚧自然种群生命表,采用排除作用控制指数法进行关键因子分析.结果表明,自然死亡是该虫种群的关键死亡因子,一龄若虫为关键死亡阶段;其他因子控制作用指数大小依次是未知死亡、捕食、昆虫寄生和病原寄生,说明天敌控制作用中,捕食是最重要的控制因子,然而,当地寄生性与捕食性天敌较少,不足以对松突圆蚧自...

| Abstract: | Using the methods of Berryman(1968) and exclusion index of population control(EIPC),the life table of the pine armored scale population was constructed.Results showed that natural death was the key factor affecting the natural populations,and the 1st instar nymph was the key of death stage.The other factors were unknown death,predation,insects and pathogens as order which effected on the EIPC.The results also showed that the predator was the most important control factor in the role of natural enemies contr... |
