摘　　要：通过测定菊小长管蚜在不同温度下生长繁殖的实验结果 ,组建了其特定年龄生命表 .结果表明 :菊小长管蚜生长繁殖的最适温度在 2 2～ 2 5℃之间 ;高温下菊小长管蚜发育历期特别是生育期明显缩短 ,产仔高峰期提前 ,但平均每雌产仔数目减少 ;不同温度下的存活曲线表明 ,高温下菊小长管蚜前期死亡率较低 ,繁殖后期较高 。Based on results of growth and reproduction of Macrosiphum sanborni(Gillete) under different temperature,the life tables were constructed.It showed that the optimal temperature of Macrosiphum sanborni was from 22 to 25 ℃.It developed faster,in high temperature condition (31 ℃), the reproduction duration was shorten significantly,and the date in peak reproduction rate was ahead of time but the number of nymphs per virginogenia decreased.The survivorship curve showed that in high temperature condition the mortality was low before reproduction,but high in the late period of reproduction.In low temperature condition the curve line was type Ⅱ.
