烟草花叶病是烤烟生产上的重要病害,近年来多次暴发流行,对烟叶的产量和质量影响极大,经济损失严重。我们的研究证明,引起我省烟草花叶病的病毒主要是黄瓜花叶病毒(CMV),占花叶病发病总数的85%以上。CMV 是由蚜虫传播的非持久性病毒,病害的传播和流行,主要受蚜虫的消长和迁飞的影响。而蚜虫的消长,则受环境因素的支配以及天敌数量的制约。因此,如果掌握了这些与蚜虫消长有关的因素及其规律,就能够对 CMV 的发生程度和流行时期进行预测预报,为防治工作提供依据并提前作好准备。
Tobacco mosaic disease is an important disease in the production of flue-cured tobacco. In recent years, it has repeatedly outbreaks and epidemic, greatly affecting the yield and quality of tobacco leaves, with serious economic losses. Our research shows that the main cause of tobacco mosaic disease in our province is cucumber mosaic virus (CMV), accounting for more than 85% of the total incidence of mosaic disease. CMV is a non-persistent virus transmitted by aphids. Its spread and spread are mainly affected by the growth and migration of aphids. The growth and decline of aphids, are subject to environmental factors and the number of natural enemies constraints. Therefore, if we master these factors and their laws related to the growth and decline of aphids, we can forecast and forecast the occurrence and prevalence of CMV so as to provide the basis for prevention and treatment and prepare ahead of time.
