摘要
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。
Ground dwelling and predating beetles, Carabidae （ground beetles） and Staphylinidae （rove beetles）, are two important groups of predating insects in agricultural ecosystems. They have high species richness and population density and play crucial role in controlling pest insects and maintain health running of agricultural ecosystems. It is therefore very important to investigate their species composition, abundance and population dynamics （especially those changes relating to the pests）, when pest control is mainly considered. According to our long-termed studies, we select here two methods, pitfall traps and haystick traps and introduce their general principle, usage, techniques and comparability in the field and procedures how to use them. We also discuss briefly how to build up sampling plots in the field and sampling bias that may disturbe the result analysis. We hope that this introduction may be helpful for field investigations..
