近年来,金纹细蛾在河北省中南部苹果产区时有发生。主要以幼虫潜伏在叶背面取食叶肉危害,被害部位仅剩表皮,外观成泡囊状,幼虫潜伏其中。叶的正面被害部位则呈黄绿色网眼状虫疤。严重时一个叶片上有泡囊10余个,使整个叶片皱缩,导致提前落叶,造成减产,果品品质下降。一、越冬化成虫羽化前的防治。在河北省中南部金纹细蛾一般每年发生5代。最后一代幼虫于11月上旬,在被害叶中化蛹越冬。因此,落叶后至发芽前 In recent years, the gold moths in apple production in central and southern Hebei Province have occurred. Lying mainly in the back of larvae fed on the back of the leaf damage, only the epidermis damaged parts, the appearance of vesicular cysts, larvae lurking them. The frontal leaves of the leaves are yellow-green mesh-like insect scars. In severe cases, there are more than 10 vesicles on one leaf, causing the entire leaf to shrink, leading to early deciduous leaf, resulting in reduced yield and declining fruit quality. First, the winter before the emergence of adult control. In central and southern Hebei Province, gold moth generally occur 5 generations a year. The last generation of larvae in early November, the injured leaves of the pupal wintering. Therefore, after deciduous to germinate
