Pitfall traps were used to sample Carabidae in agricultural land of the Spercheios valley, Fthiotida, Central Greece. Four pairs of cultivated fields were sampled. One field of each pair was located in a heterogeneous area and the other in a more homogeneous area. Heterogeneous areas were composed of small fields. They had high percentages of non-cropped habitats and a high diversity of land use types. Homogeneous areas were composed of larger fields. They had lower percentages of non-cropped habitats and a lower diversity of land use types. One pair of fields had been planted with cotton, one with maize, one with olives and one with wheat. Altogether 28 carabid species were recorded. This paper describes the study areas, the sampling methods used and presents the data collected during the study. Neither heterogeneous nor homogeneous areas had consistently higher abundance levels, activity density levels, species richness levels or diversity levels. However, significant differences were seen in some of the comparisons between heterogeneous and homogeneous areas.
在希腊中部弗西奥蒂达州斯佩尔基奥斯河谷的农田中，使用陷阱诱捕法对步甲科昆虫进行采样。对四对耕地进行了采样。每对中的一块田地位于异质区域，另一块位于更均质的区域。异质区域由小块田地组成。它们有较高比例的非作物栖息地和多种土地利用类型。均质区域由较大的田地组成。它们有较低比例的非作物栖息地和较低的土地利用类型多样性。一对田地种植了棉花，一对种植了玉米，一对种植了橄榄，一对种植了小麦。总共记录了28种步甲科物种。本文描述了研究区域、所使用的采样方法，并呈现了研究期间收集的数据。无论是异质区域还是均质区域，都没有始终具有更高的丰度水平、活动密度水平、物种丰富度水平或多样性水平。然而，在异质区域和均质区域之间的一些比较中发现了显著差异。
