为评估平卧菊三七作为载体植物扩繁烟蚜茧蜂的适合性，测试了烟蚜在平卧菊三七、以及常见寄主植物烟草、茄子和二年生萝卜共4种寄主植物上的发育历期和繁殖力等，获得了净增殖率、周限增长率、内禀增长率、平均世代周期、种群加倍时间等主要生命表参数，比对了不同载体植物上的烟蚜对烟蚜茧蜂个体发育的影响。结果显示：这4种寄主植物上烟蚜的发育历期为二年生萝卜(22.79 d)＞平卧菊三七（22.22 d）＞烟草(22.01 d)＞茄子(18.92 d)，茄子上最短，其他三种寄主植物上无显著差异；单头烟蚜总产仔量为二年生萝卜（63头）＞平卧菊三七（52头）＞茄子（43头）＞烟草（41头）；内禀增长率rm值为茄子（0.283）＞二年生萝卜（0.278）＞平卧菊三七（0.277）＞烟草（0.255）。表明相同条件下，相对于烟草，烟蚜偏好取食平卧菊三七；平卧菊三七作为载体扩繁出的烟蚜茧蜂僵蚜，体型与烟草、二年生萝卜扩繁者的差异不显著。平卧菊三七可用作大量扩繁烟蚜及烟蚜茧蜂的载体植物。

英文摘要:

In order to verify whether Gynura divavicatais a suitable host plants for propagatingAphidius gifuensis, we studied the developmental duration and fecundity of Myzus persicae on G. procumbens,Nicotiana tabacum, Solanum melongenaand Raphanus sativus.Meanwhile, we got the innate capacity for increase ( rm ) and other major life table parameters, compared the effects of Myzus persicaewhich from different host plants on Aphidius gifuensis's development. The results showed that the developmental durations of M. persicae on 4 host plants were R. sativus(22.790 d)＞G. procumbens（22.225 d）＞ N tabacum (22.005 d)＞S. melongena (18.924 d), there were no significant differences on the other 3 plants except S. melongena which was shortest. The reproduction ofM. persicaeon different hosts was R. sativus（63）＞G. procumbens（52）＞S. melongena（43）＞N. tabacum（41）;rmwas S. melongena（0.283）＞R. sativus（0.278）＞G. procumbens（0.277）＞N.tabacum（0.255). Analysis of these results showed that under the same conditions, M. persicae prefer feeding S. melongena rather than feeding N. tabacum; the A. gifuensis's development were no significant differences between G. procumbensandS.melongena, Raphanus sativus. In summary, G. procumbens can be used as a suitable host plant to propagate large-scale M. persicae and A. gifuensis.
