烟蚜(Myzus persicae)是烟草上的重要害虫,主要为害烟草叶片、花蕾及嫩尖,其发生期长,为害重,严重影响烟叶的品质和产量。同时还能传播病毒病(CMV 和 PVY)危害烟草。为改变喷雾防治效果差、持效期短、对天敌杀伤大以及水源不便的困难,我们研究采用缓释剂涂茎治蚜的方法,取得了满意的效果。 Myzus persicae, an important pest on tobacco, mainly harms tobacco leaves, flower buds and tender tips. Its occurrence period is long and harmful, which seriously affects the quality and yield of tobacco leaves. At the same time can also spread viral diseases (CMV and PVY) endanger tobacco.
