| 摘 要： | 本研究采用在相同生境不同发生年代的异地取样法,仅用一年时间,对一年一代的青杨天牛(Saperda Populean L.)编制了7个单世代生命表,与用常规累积同种害虫生命表的方法相比缩短了时间,并与通过五年编制的5个单世代生命表比较,存活曲线相同,关键因子一致,各致死因子死亡率的大小顺序也基本一致。说明这种累积生命表的方法在实践中是可行的。

| Abstract: | The sampling method in different forest land where the pests emerged in different times in the same Environment was used on establishing life tables of Saperda populnea L. Seven single generatien life tables were established in one year. This way spent shorter time as compared with the normal method accumulating life tables. The survivalship curves are the same, key factors are the same and the order of lethal ratio of each factor is nearly the same as compared with five tables at the same forest land in five years. This shows that the method accumulating life tables is feasible in practice. |
