The green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), is an important agricultural pest with a wide range of host plants. To study effects of host species on the life history traits of M. persicae, aphids were individually reared on five host plants: Brassica campestris L. (Brassicales: Brassicaceae), Capsicum annuum L. (Tubiflorae: Solanaceae), Nicotiana tabacum L. (Tubiflorae: Solanaceae), Raphanus sativus L. (Brassicales: Brassicaceae), and Vicia faba L. (Rosales: Leguminosae). TWOSEX-MSchart software was used for the statistical analysis according to the age-stage, two-sex life table theory. The results showed that the shortest preadult stage and adult/total prereproductive period of M. persicae were 6.48, 0.19, and 6.67 d on V. faba, respectively. While the adult and total longevity of M. persicae on R. sativus (25.00 and 31.62 d) and N. tabacum (24.40 and 30.56 d) were significantly longer than that on the other three hosts, as was the reproductive period. The fecundity of M. persicae on R. sativus (80.83 nymphs per female), N. tabacum (71.72 nymphs per female), and V. faba (70.39 nymphs per female) was also greater than that on B. campestris and C. annuum. It was demonstrated that V. faba, R. sativus, and N. tabacum were more suitable plants for the growth of M. persicae exhibiting a shorter preadult stage, longer longevity, and greater fecundity than the remaining two species, as confirmed by the higher intrinsic rate of increase and net reproductive rate.
绿桃蚜，桃蚜（半翅目：蚜科），是一种广泛的宿主植物的重要农业害虫。为了研究宿主物种对桃蚜生活史特征的影响，将蚜虫分别饲养在五种宿主植物上：油菜（十字花科：十字花科）、辣椒（管状花科：茄科）、烟草（管状花科：茄科）、萝卜（十字花科：十字花科）和蚕豆（蔷薇科：豆科）。根据年龄-阶段、两性生命表理论，使用 TWOSEX-MSchart 软件进行统计分析。结果表明，桃蚜的最短幼期和成虫/总预生殖期分别为 6.48、0.19 和 6.67d，在蚕豆上。而桃蚜的成虫和总寿命在萝卜（25.00 和 31.62d）和烟草（24.40 和 30.56d）上显著长于其他三种宿主，生殖期也是如此。桃蚜在萝卜（80.83 头/雌）、烟草（71.72 头/雌）和蚕豆（70.39 头/雌）上的繁殖力也大于油菜和辣椒。证明萝卜、烟草和蚕豆是更适合桃蚜生长的植物，其幼期较短，寿命较长，繁殖力较强，比其余两种植物具有更高的内禀增长率和净生殖率。
