| 摘 要： | 对影响陕西烟草蚜传病毒病发生的烟田有翅蚜迁飞，越冬毒源、烟草不同移栽期、不同品种等因素进行了研究。结果表明，烟草蚜传病毒病的发生与有翅蚜的第１次迁飞期的长短；早晚和有翅蚜量密切相关；有翅蚜的第２次迁飞与烟草蚜传病毒病的相关性不大；同一烟草品种移栽越早，大田发病越重；不同烟草品种间存在不同的抗病性；越冬蚜量和越冬毒源似乎不是影响烟草蚜传病毒病的主要因素。

| Abstract: | Research resuits shown that the incidence of tobacco virus diseases spread by aphis was highly correlated with the beginning time and the length of the first migration period of alate aphis and the amount of alate aphis in this period, The earlier the tobacco seedlings were transplanted, the severer the virus diseases took place. The tolerance of varieties tobacco breeds to virus shown obviously difference. It seems that the occurence of tobacco virus diseases has nothing to do with the amount of over winter aphis and virus over wintered and the second migration of aphis. |
