摘要: 农田节肢动物多样性具有病虫害控制、传粉等价值,选择一种或多种适宜、准确且高效的取样方法和指示类群来衡量农田节肢动物多样性是一项基础性工作。本文通过地表陷阱法、挂盆陷阱法、扫网法、目测计数法和吸虫器法在有机管理和常规管理农田区的不同农业生境类型中取样,比较不同方法对不同生物类群的捕获效率、经济成本、响应敏感性等。研究发现在捕获效率方面,地陷法和挂盆法最高,其次是扫网法,而吸虫器法和目测计数法较差。挂盆法对步甲、蜘蛛、蜂类和瓢虫类群的捕获效率较佳。陷阱法主要适用于蜘蛛和步甲的取样,扫网法也可用于蜘蛛和瓢虫的取样。在经济成本方面,地陷法的成本最低,扫网法的总成本最高。每种取样方法下仅有个别类群个体数量具有较好的响应敏感性,如地陷法的蜘蛛目个体数和步甲科个体数、挂盆法的总个体数、蜂类个体数和瓢虫科个体数、扫网法的直翅目个体数和半翅目个体数等。在此基础上,综合类群经济价值,操作难易,类群鉴定难度,被动取样程度,是否受取样人影响等比较发现:地陷法对步甲和蜘蛛的取样的综合效果最佳,而不同取样方法下多种类群的组合能更好的监测和评价农田节肢动物多样性的整体情况。地陷法捕获步甲或/和蜘蛛以及挂盆法调查蜂类的组合是基于本研究得出的调查农田节肢动物多样性最佳组合。

Abstract: Farmland biodiversity of arthropod has the huge value of pest control, pollination, etc. It is a basic work to select one or more appropriate, accurate and efficient sampling methods and indicator taxa to assess farmland arthropod diversity. In this paper, the surface trap cup method, coloured pan traps, sweeping method, visual counting, and vacuum-suction method were used to sample arthropods in different types of agricultural habitats within organic managed and conventional managed farmland. The capture efficiency, economic cost and response sensitivity of different methods to different assemblages were compared. The study found that surface trap cup method and coloured pan traps had the highest capture efficiency, followed by sweeping method and vacuum-suction method. Visual counting was lowest. Coloured pan traps was more efficient to capture carabids, spiders, bees and ladybugs. Surface trap cup method was mainly applicable to the sampling of ground spiders and carabids. The sweeping method could also be used to sample spiders and ladybugs. In terms of economic costs, the most economical method was surface trap cup method that was used to obtain the carabids or spiders. The highest cost was the sweeping method due to low capture efficiency of spiders. Under each sampling method, only the abundance of several certain taxa had a good response sensitivity to difference of habitats and management, such as the number of spiders and carabids by the surface trap cup method, the total number of specimens, the number of bees, and the number of ladybugs by the coloured pan traps, the number of Orthoptera and Hemiptera by the sweeping method. Moreover, a comparison was made after taking into account the economic value of the taxon, the difficulty of operation, the difficulty of taxon identification, the degree of passive sampling, and whether the taxon was influenced by different sampling people. The best comprehensive methods were the sampling of carabids and spiders by surface trap cup method. The combination of multiple taxa under different sampling methods can better evaluate and monitor the overall situation of farmland biodiversity. The best combination to investigate farmland arthropod diversity was to sample crabids or spider by surface trap cup method and to sample bees by coloured pan traps.
