活动于土壤地表的捕食性甲虫——步甲与隐翅虫,种类丰富、种群密度高、在农田害虫控制和农业生态系统平衡维持中发挥着重要的作用,采集调查这两类昆虫的种类、数量和变化,特别是与所捕食害虫种群动态相关联的季节变化,对于害虫控制是极为重要的。根据作者多年经验,筛选两种有效的田间采集与取样方法——陷阱法和草堆诱集法,本文重点介绍它们的基本原理与使用情况、田间设置的技术关键与规范、操作流程等,并对它们的样地设置原则及注意事项进行了简要讨论,从而方便这两项技术的推广使用。
The predatory beetles, Carabus and Paederus, which are active on the soil surface, are rich in species and have high population densities. They play an important role in the control of farmland pests and the balance of agricultural ecosystems. The types of insects, The quantity and changes, especially the seasonal changes associated with the dynamics of the population of predators, are extremely important for pest control. According to the author’s many years of experience, two effective methods of harvesting and sampling in the field, ie trap method and straw-trapping method, are screened out. This article focuses on their basic principle and application, the key and specification of field setting, operation flow and so on. A brief discussion of their sample setting principles and precautions was made to facilitate the promotion and use of these two technologies.
