试验表明，在江西的气候条件下，烟草ＣＭＶ的传播介体（烟蚜）可以安全越冬。在４月中旬至５月中旬（还苗至团棵期），日均气温１７．２～２１．５℃，５日降雨量５０ｍｍ以下、相对湿度８０％以下，有利蚜虫扩散迁飞抵烟田传毒和繁殖，病情重；有翅蚜迁飞高峰后５～１０ｄ即始病，在南昌地区始病期在５月上中旬，盛期在６月上中旬。品种间抗性差异显著，施用Ｎ肥过多、移栽期推迟和离毒源作物近的烟田，发病早而重。
Experiments show that under the climatic conditions in Jiangxi, tobacco CMV transmission media (aphids) can safely wintering. In mid-April to mid-May (seedlings to the Mission period), the average daily temperature of 17.2 ~ 21 .5 ℃, on the 5th rainfall less than 50mm, relative humidity below 80%, the favorable aphids spread to fly to the tobacco field Poisoning and reproduction, the disease is heavy; winged aphids 5 to 10d after the peak of the disease began to migrate in Nanchang area onset in mid-May, the peak in mid-June. There was significant difference in resistance among cultivars. The application of excessive N fertilizer, postponed transplanting and tobacco fields near the source crops were earlier and heavier.
