二点委夜蛾是2005年发生并被中国动物研究所鉴定的玉米新害虫。由于该害虫易与黄地老虎在形态上混淆,因此目前的发生范围尚未澄清,且很易延误防治。今年各地加强了对二点委夜蛾的监测和研究,根据黑光灯诱测,6月10日各地蛾量骤增,进入第一代蛾高峰,预计6月下旬-7月玉米苗期将受到二点委夜蛾危害,发生程度为中等偏重,危害程度重于上年,范围有扩大趋势。一、虫态识别经过近年研究,目前对其形态有初步确定, Two members of the night-stage moth is occurred in 2005 and was identified by the China Animal Research Institute of new corn pests. Because of the morphological confusion between the pest and the yellow tiger, the extent of the current occurrence has not yet been clarified, and it is very easy to delay the prevention and treatment. According to the black light test, the amount of moths plummeted on June 10 and entered the peak of the first generation of moths. It is estimated that the maize seedling stage will be affected in late June-July of this year Two-point exiguous nightworm damage, the degree of occurrence is moderately weighted, the degree of harm heavier than the previous year, the scope of the expansion trend. First, the identification of insect status After recent years of research, the current shape of its initial determination,
