近年来,斜纹夜蛾在江苏沿江地区发生越来越普遍,为害也逐年加重,斜纹夜蛾种群发生数量回升迅速,已由一个次要的偶发性害虫逐渐成为蔬菜和豆科作物上比较重要的害虫,为害造成的损失大幅度上升,已成为蔬菜等双子叶作物上主要害虫之一,亟需引起高度重视,切实强化预测预报,选择高效药剂,适期喷药控制,力争把斜纹夜蛾的发生危害损失控制在最低限度。为此,我们于2014~2016年进行了多种药剂不同时期用药对斜纹夜蛾防治效果比
In recent years, Spodoptera litura has become more and more common along the Yangtze River in Jiangsu Province, and its damage has also been increasing year by year. The population of Spodoptera litura rebounded rapidly and it has become more important that vegetables and leguminous crops have been gradually replaced by a secondary sporadic pest Pests and damage caused by damage have risen sharply and have become one of the major pests on crops such as vegetables and other dicotyledonous crops.
