| 摘 要： | 综述了烟粉虱Bemisia tabaci对双生病毒的获取、传播及存留等方面的特性。烟粉虱最短的获毒和接种时间为15～30 min；双生病毒在烟粉虱体内可存留1至数周，有的终身存在。烟粉虱对双生病毒的传毒效率除了随其获毒及传毒时间的延长、传毒烟粉虱个体数量的增加以及病毒体浓度的增加而提高外，还与烟粉虱的龄期及性别有关。双生病毒除了在植物与粉虱之间直接传播外，还可通过烟粉虱交配及经卵携带的途径在烟粉虱个体和代别间进行传播。寄主植物、双生病毒的一些特殊蛋白以及烟粉虱内共生菌产生的GroEL蛋白，都可影响烟粉虱携带的双生病毒种类及传毒的可能性。双生病毒可对烟粉虱的发育、存活和生殖产生不利或有利的影响。雌成虫携带番茄黄化曲叶病毒（tomato yellow leaf curl virus, TYLCV）后，存活力和生殖力均下降； 而携带番茄斑驳病毒（tomato mottle virus, ToMoV）后，生殖力提高。此外，植物感染双生病毒后，其对烟粉虱的适合性可能提高。

| Abstract: | This article reviews the acquisition, transmission and retention of geminiviruses by the whitefly, Bemisia tabaci. Minimum time required for acquisition and inoculation of geminiviruses by the whitefly is 15-30 min. Geminiviruses may be retained in their vector for one to several weeks, and sometimes for the entire life of the vector. Transmission efficiency increases with increase of acquisition time and inoculation time, or increase of the number of whiteflies used for inoculation and virus concentration. Moreover, the efficiency of transmission varies with age and gender of the insect vector. In addition to the direct transmission between plant and whitefly, geminiviruses can also be transmitted through mating and oviposition (transovarial transmission) among whiteflies. What geminiviruses that can be acquired by whitefly and the possibility for virus transmission are affected by the host plants, the special protein of geminiviruses as well as the GroEL proteins synthesized by endosymbionts of the vector. Geminiviruses may have favourable or unfavourable effects on the development, survival and reproduction of the whitefly. Whiteflies carrying tomato yellow leaf curl virus(TYLCV) show lower levels of survival and fecundity, while those carrying tomato mottle virus (ToMoV) show higher fecundity, compared with their counterparts. In addition, host plants infected by geminiviruses may increase their suitability to whiteflies. |
