近几年,我国草地螟的研究工作,已取得了很大进展,特别是关于草地螟越冬基地的研究,为了解我国草地螟发生的虫源关系,分析迁飞路径,开展预测预报工作打下了基础。国内外有关昆虫迁飞过程的研究资料表明,迁飞昆虫住高空一般多呈被动飞行,其飞行的方向和速度和当时的气流相一致。本文就是根据这一结果,采用草地螟越冬虫源基地内,越冬代草地螟灯诱羽化蛾量与我国东北地区出现的较大范围的蛾量突增资料(1980—1983,以
In recent years, great progress has been made in the research on Meadow Borer, especially on the overwintering base of Meadow Stem Borer. In order to understand the relationship between Erechiasatis and its origin and to analyze the migration path and predict forecast work, basis. Domestic and foreign research on insect migration process data show that migratory insects are mostly passive at high altitude flight, the direction and speed of its flight and the current air flow consistent. This article is based on the results, the use of more than the grasshopper overwintering source base, the winter mulberry borer light trap moths and northeastern China appear a large range of moths sudden increase in data (1980-1983 to
