现在再来谈谈另一个极其重要的科学问题——植物保护事业的组织经济方面的问题。在这里不能不指出一件令人惋惜的事实:至少害虫防治的经济组织问题没有受到应有的重视。 昆虫学家在研究一种害虫的防治方法时普通是把自己的任务局限於追求这些方法的高度技术上的效果,亦即要有很高的杀虫率;或者局 Now let us talk about another extremely important scientific issue - the organizational economy of plant protection. Here, we can not fail to point out the regrettable fact that at least the issue of the economic organization of pest control has not received the attention it deserves. Entomologists, when studying the methods of pest control, generally limit their tasks to the highly technical effects of pursuing these methods, that is, having a high insecticidal rate; or
