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。
In order to evaluate the suitability of Panax notoginseng as a vector plant for the propagation of Aphidius pulchricornis, the developmental history of Myzus persicae on four kinds of host plants of Panax notoginseng, as well as the common host plants of tobacco, eggplant and biennial radish Period and fecundity, the main life table parameters such as net growth rate, weekly growth rate, intrinsic rate of increase, average generation cycle, population doubling time were obtained. The impact of individual development. The results showed that the developmental duration of Myzus persicae on these four host plants was 22.79 d> 22.22 d> 22.01 d> 18.92 d, eggplant was the shortest, and the other There were no significant differences among the three host plants; the total litter size of single-headed aphids was two-year-old radish (63 heads)> three heads of shrubs (52 heads)> eggplant (43 heads)> tobacco Rate rm values were Eggplant (0.283)> biennial radish (0.278)> Panax notoginseng (0.277)> tobacco (0.255). Under the same conditions, relative to the tobacco, the tobacco aphid prefer to feed Herba Platyrhoea Panax notoginseng; PanPen chrysanthemum Panax notoginseng as a carrier to expand the tobacco aphid Myzus persicae, body size and tobacco, biennial radish multiplier difference is not Significant. Pan-chrysanthemum Panax notoginseng can be used as a large-scale propagation of aphids and tobacco aphid Braconidae vector plants.
