背景植物病原性菜豆花叶病毒与其昆虫载体之间存在着复杂的关系。对菜豆花叶病毒的相互作用及其载体的繁殖知之甚少。已知烟粉虱传播多种菜豆花叶病毒，而B。烟粉虱，特别是B和Q“生物型”，伴随着菜豆花叶病毒的流行。其中一种病原是中国番茄黄化曲叶病毒（TYLCCNV）。方法/主要发现在这项研究中，我们比较了两个“生物型”或假定物种的粉虱B的产卵量和繁殖力。烟粉虱，包括外来入侵的B和来自中国浙江的本地ZHJ 1，以健康或TYLCCNV感染的烟草植物为食。粉虱卵巢由12-22个端营养型卵巢管组成。根据卵母细胞的形态和卵黄含量的高低，将卵巢管中的卵母细胞分为四个发育阶段（I ~ IV）。与健康植株相比，取食TYLCCNV感染烟草的雌性卵巢中未成熟卵母细胞（II、III期）和成熟卵母细胞（IV期）的比例显著较高。此外，B烟粉虱在感染TYLCCNV的烟草植株上的产卵量在发育早期显著增加。而ZHJ 1号粉虱取食TYLCCNV感染和未感染寄主植物后，不同发育时期的卵母细胞比例和产卵比例无显著差异。结论/意义入侵性B粉虱通过取食感染菜豆花叶病毒的植物，增加产卵量，实现繁殖力。
Background Plant-pathogenic begomoviruses have a complex association with their insect vectors. The interactions of begomoviruses and reproduction of their vectors are poorly understood. Bemisia tabaci is known to transmit many begomoviruses, and the spread of B. tabaci, especially the B and Q ‘biotypes’, has been accompanied by the epidemics of begomoviruses. One of these identified disease-causing agents was Tomato yellow leaf curl China virus (TYLCCNV). Methodology/Principal Findings In this study, we compared the egg production and realized fecundity of two ‘biotypes’ or putative species of the whitefly B. tabaci, including the alien invasive B and the indigenous ZHJ1 from Zhejiang, China, feeding on either healthy or TYLCCNV-infected tobacco plants. The ovary of the whitefly was composed of 12–22 telotrophic ovarioles. According to the morphology of the oocytes and level of yolk content, oocytes in ovarioles were divided into four developmental phases (I-IV). Significantly higher proportion of immature oocytes (phase II, III) and mature oocytes (phase IV) was observed in ovary of females that fed on TYLCCNV-infected tobacco compared to that on healthy plants. Moreover, there was significant increase of eggs laid of B whitefly that fed on TYLCCNV-infected tobacco plants during the early developmental stages. In contrast, the proportion of oocytes of different developmental phases and eggs laid had no significant differences between ZHJ1 whiteflies feeding on TYLCCNV-infected and non-infected host plants. Conclusions/Significance The invasive B whitefly benefits from feeding on a begomovirus-infected plant through increased egg production and realized fecundity.
