本文介绍群体饲养生命表的资料分析基本原理及转换为个体生命表的方法。群体饲养生命表的记录实际上即年龄-龄期两性生命表的N矩阵,而每日所有雌虫的总繁殖记录即为Ftotal矩阵。利用N矩阵与Ftotal矩阵可以计算S矩阵、F矩阵及各种群参数。以桃蚜Myzus persicae和马铃薯块茎蛾Phthorimaea operculella为例,阐明群体饲养生命表分析的理论依据,证明群体饲养生命表得到的各项参数可靠,并介绍了一种将群体饲养生命表转化为个体生命表的方法。比较了群体饲养生命表和个体饲养生命表的特点。利用群体饲养研究昆虫生命表可以节省大量人力、时间与经费,群体饲养生命表可用于设计大量饲养生物防治天敌、鱼与鸟的饲料昆虫以及可供人类食用的昆虫。
