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。 In this study, the off-site sampling method was used in different generations of the same habitat. In a year, seven single-generation life tables of one generation of Saperda Populean L. were prepared, Compared with the five single-generation life tables, which were compiled in five years, the survival curves were the same, the key factors were the same, and the order of the mortality of each lethal factor was basically the same. This method of accumulating life tables is feasible in practice.
