B型烟粉虱（同翅目：粉虱科）的入侵能力通常与其比非B本土生物型更广泛的宿主范围有关。然而，关于B生物型和非B生物型在不同宿主植物物种上的相对性能的实验研究很少。在这里，我们比较了B生物型和本土非B生物型（中国ZHJ-1）的性能。来自中国浙江的烟粉虱寄生在五种常见的栽培寄主植物上，每种寄主植物来自不同的科：棉花、烟草、卷心菜、南瓜和菜豆。我们还研究了饲养宿主植物对B生物型性能的影响。总体而言，B生物型对五种植物的表现远优于土著非B种群。在烟草、卷心菜和菜豆上，ZHJ-1没有个体完成发育至成年，而B生物型在所有三种植物上都成功地从卵发育至成年。在南瓜上，B生物型比ZHJ-1存活更好，发育到成年期更早，繁殖力更高。这两种生物型在棉花上的表现更为相似，但即使在这种植物上，B生物型雌性成虫的寿命也几乎是ZHJ-1的两倍，并且可能实现了更高的终生繁殖力。B生物型还表现出相当大的能力，以适应替代寄主植物，提高生存和繁殖，在高度适合和边缘适合的寄主植物。我们认为B生物型的寄主范围是B.烟粉虱可能比某些土著生物型的烟粉虱分布更广，B生物型相对于非B生物型的这种优势可能有助于烟粉虱在田间入侵和取代某些土著生物型。
The capacity of the B biotype of the whitefly, Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae), to invade has often been linked to its presumably wider host range than the non‐B indigenous biotypes. However, there are few experimental studies of the relative performance of the B biotype and non‐B biotypes on different host‐plant species. Here, we compared the performance of the B biotype and an indigenous non‐B biotype (China‐ZHJ‐1) of B. tabaci from Zhejiang, China on five commonly cultivated host plants, each from a different family: cotton, tobacco, cabbage, squash, and kidney bean. We also examined the effect of rearing host plants on the performance of the B biotype. Overall, the performance of the B biotype on the five species of plants was much better than that of the indigenous non‐B population. On tobacco, cabbage, and kidney bean, no individuals of ZHJ‐1 completed development to adulthood, whereas the B biotype developed successfully from egg to adult on all three plants. On squash, the B biotype survived better, developed to adulthood earlier and had a higher fecundity than ZHJ‐1. The two biotypes performed more equally on cotton, but even on this plant the B biotype female adults lived nearly twice as long as that of ZHJ‐1 and may have realized a higher life‐time fecundity. The B biotype also showed a substantial capacity to acclimatize to alternative host plants for improved survival and reproduction, on both highly suitable and marginally suitable host plants. We conclude that the host range of the B biotype of B. tabaci may be much wider than those of some indigenous biotypes, and this advantage of the B biotype over the non‐B biotypes may assist in its invasion and displacement of some indigenous biotypes in the field.
