粘虫为我国重要农作物害虫之一。自六十年代以来,对我国粘虫迁飞的研究取得了重大成就,明确了粘虫的逐代迁飞为害和不同发生区的虫源性质等问题,这就为我国开展粘虫异地预测提供了科学依据。本文扼要介绍了我们从1979年以来对粘虫几个主要发生世代区的发生趋势进行了异地预测。其主要方法是制定统一测报调查方法,在不同发生世代区选有代表性的测报站进行系统调查,并通过“模式电报”的方式传递虫情信息,结合发生区的作物条件以及天气预报等进行综合分析,并结合不同世代区的历史资料,运用电子计算机进行判别分
Mythimna separata is one of the important pests in our country. Since the 1960s, great achievements have been made in the research on the migration of Mythimna separate of the armyworm in China. The problem of migration from armyworm to armyworm and pest origin in different areas has been clarified. The scientific basis. This article gives a brief introduction of the off-site prediction that we have made since 1979 about the trends in several major occurrences of armyworm. The main method is to formulate a unified survey method for surveys, conduct systematic surveys at selected representative stations in different generations, and transmit insect information by means of “mode telegraph”, combining crop conditions in the occurrence areas and weather forecasting Comprehensive analysis, combined with different generations of historical data, the use of electronic computers to distinguish
