在室内4个温度（15、20、25和30℃）下分别测定、比较夹竹桃蚜实验种群的存活曲线和生命表各参数差异.结果表明：夹竹桃蚜在15℃下呈Ⅱ型存活曲线，而在其他3个温度下都呈Ⅰ型存活曲线.夹竹桃蚜的平均世代历期T随温度的升高而缩短，分别从15℃的24.4 d到30℃的8.2 d.夹竹桃蚜的瞬时增长率r和周限增长率λ在15℃最小，分别为0.045和1.046；相反二者在20℃最大，分别为0.136和1.146.净增殖率R0在20℃最高（9.170），其次为25℃（4.669）、15℃（3.017），最小为30℃（2.825）.可见20℃是饲养夹竹桃蚜的最适温度，本研究可为采用夹竹桃蚜大规模扩繁捕食性天敌提供依据.

We determined and compared the indexes of the growth and development,survivorship and reproduction of the aphid Aphis nerii feeding on Nerium indicum at four constant temperatures(15、20、25 and 30℃)in laboratory. Results showed that the populations’survival curves under the temperatures of 20、25 and 30 were of DeeveyⅠ,exceptⅡat 15℃. The mean generation time(T)decreased with the increasing of temperature, and those of A. nerii were 24.4 d and 8.2 d at 15℃and 30℃,respectively. The instantaneous growth rate(r) and finite rate of increase(λ)of A. nerii were the lowest at 15 ℃,with the values of 0.045 2 and 1.046, whereas they were highest at 20℃,with the values of 0.136 and 1.146,respectively. The net reproductive rate (R0)of A. nerii was the highest at 20℃,with the value of 9.170,followed by 4.669 at 25℃,3.017 at 15℃and 2.825 at 30 ℃,respectively. The present study provided foundation for the mass rearing of predatory insects,such as ladybird,lacewing and hoverfly.
