防治害虫,必须以它的发生规律为依据,并且针对它发生过程中的薄弱环节,采取防治措施,就能收到防治效果。这是治虫的基本原则。因此,如何正确理解害虫的发生规律,关系重大。只有正确理解害虫的发生规律,治虫工作才有明确的指导思想。为实现四个现代化向科学进军,把植保工作推向先进水平,现把这个问题提出来讨论,不当之处,望批评指正。什么是害虫的发生规律?翻开农业昆虫学的书本和杂志一看,给人的印象是,似乎了解害虫的生活史就是掌握它的发生规律。所谓薄弱环节,也是由生活史中去寻找。害虫发生的预测预报工作和一切防治措施,都是以此为依据。我们可以把它叫做以生活史为中心的害虫发生规律观,这种思想普遍存在。
Pest control must be based on the law of its occurrence, and in the process of its occurrence of weak links, take prevention and control measures, you can receive control effect. This is the basic principle of pest control. Therefore, how to correctly understand the law of occurrence of pests is of great importance. Only by correctly understanding the law of occurrence of pests can there be a clear guiding principle for pest control. To advance the four modernizations to science and push plant protection work to the advanced level, we now put this issue to discussion, improperness and hope of criticism and rectification. What is the law of occurrence of pests? Open the book of agricultural entomology and magazine a look, giving the impression that it seems to understand the pest’s life history is to grasp the law of its occurrence. The so-called weak links, but also from the history of life to find. Pest occurrence prediction and prevention of all work, are based on this. We can call it the law of the pests that have a history of life as the center, and this idea prevails.
