试验结果表明,陕西烟田蚜传病毒病的介体和初侵染毒源均来自当地冬油菜田;蚜传病毒病的主要种类有CMV、TEV和PVY;有翅桃蚜迁入烟田有2个高峰期,第1高峰期出现在5月中旬,第2高峰期出现在6月中旬;各品种之间存在着不同的耐病性,其中MsB07、MsG02耐病;以陕西泾阳1994～1998年5年的烟草病情资料、当地气象资料和相关资料建立了烟田蚜传病毒病发病率(Y)预测预报模型:r=-6.909+0.011528 X_4+0.0026 X_5+0.001785 X_(12)+0.448X_(13)。
The results showed that the mediators and initial infection sources of aphids in Shaanxi tobacco field were all from the local winter rape field. The major species of the virus transmitted by aphids were CMV, TEV and PVY. 2 peaks, the first peak appeared in mid-May, the second peak occurred in mid-June; there is a different disease resistance between varieties, including MsB07, MsG02 disease-resistant; Jingyang, Shaanxi from 1994 to 1998 5 (Y) forecast model of tobacco aphids virus was established according to the data of tobacco disease, local meteorological data and relevant data in the past years: r = -6.909 + 0.011528 X_4 + 0.0026 X_5 + 0.001785 X_ (12) +0.448X_ (13) ).
