粘虫是禾本科作物最主要的害虫之一,我国从南到北都有其为害的记载。近年来在初步掌握其生物学特性和一般发生规律的基础上,拟定了短期予测的办法和防治措施,在生产上起了一定的作用。然而,粘虫生活史中的一个重要环节——越冬问题,特别是在黑龙江省等北部地区的越冬问题,迄今尚未解决,对进一步掌握其消长规律、猖獗原因,从而进行长期予测造成障碍。这一问题引起有关单位和植保工作者的注意,并提供 Mythimna separata is one of the most important pests of gramineous crops. Our country has records of its damage from south to north. In recent years, preliminary grasp of its biological characteristics and the general rule of occurrence on the basis of the preparation of a short-term test methods and prevention and control measures in the production played a certain role. However, an important link in the life history of armyworms - wintering, especially overwintering in the northern areas such as Heilongjiang Province, has not yet been solved yet, posing an obstacle to further grasping its growth and decline and its long-term predictions. This issue has drawn the attention of the relevant units and plant protection workers and provided them
