Abstract
Data of comparative studies about carabid beetles in organically and conventionally managed winter cereal fields of central Europe, using the pitfall trapping method, were collected from the literature and unpublished data sources and were then pooled and analysed. According to an index, which was designed to calculate how much a species benefits from organic management, Carabus auratus turned out to benefit most. Some Amara species (A. familiaris, A. similata and A. aenea) as well as Pseudoophonus rufipes and Harpalus affinis also showed high index values. When analysing the traits of the carabids, the habitat preference was the most important variable for the differentiation of organic and conventional management. The stronger the preference for open field, the more the species are supported by organic agriculture. For the promotion of the agricultural carabid fauna it is suggested that weedier and less densely cropped fields be tolerated. (C) 2003 Elsevier Science B.V. All rights reserved.
