Carabidae and Staphylinidae (Col.) in swede and cauliflower fields in south-eastern Norway ARILD ANDERSEN Andersen. A. Carabidae and Staphylinidae (Col.) in swede and cauliflower fields in south eastern Norway. Fauna norv. Ser. B. 29, 49-61. During May-Oct. 1975 -81 about 20 000 carabids and 48 000 staphylinids were caught in 12 swede and cauliflower fields at Jel0Y (sand and gravel, moraine), As (clay) and Ski (clay ish moraine). Carabids were most numerous in May-June (spring breeders) and Aug. (au tumn breeders), while staphylinids were most numerous in May-July. The activity density for each species caught in each field is given, as well as the time for itS maximum activity. The three localities had a quite similar fauna, the S0rensen index of similarity for carabids being 44 for Jel0y-Ski, 62 for JeI0Y-As and 86 for As-Ski. Among the 10 most nume rous carabid species at each of the three localities, the following six were in common: Bem bidion /ampros (Herbst), Ca/athus me/anocepha/us (L.), Bembidion quadrimacu/atum (L.), Trechus quadristriatus (Schrank), Harpa/us rufipes (Degeer) and Clivina fossor (L) The same holds for the following seven staphylinid species: A/oconota gregaria (Erichson), Ami scha analis (Gravenhorst>, A/eochara bipustu/ata (L.,), Atheta fungi (Gravenhorst>, Anoty/us rugosus (Fabricius), Tachyporus hypnorum (Fabricius) and T. chrysomelinus (L) The eight most numerous carabid and staphylinid species are discussed separately. Their seasonal changes during May-Ocr.nlJer are given in histograms and comments are given on their reproduction cyclus. Arild Andersen, Norwegian Plant Protection Institute, N-1432 As-NLH, Norway. INTRODUCfION The trapping was done atJel0Y in 1975 - 81 (ex The carabids of common European crops have cept in 1977), at As in 1978- 81 and at Ski in been quite thoroughly investigated (Thiele 1979-80. 1977). This is mainly due to their value as preda At Jel0Y the soil consisted of sand and gravel tors of several pest species. The staphylinids are (moraine). This farm was situated close to the less investigated, both because of their difficult sea and the experimental field was each year a taxonomy and because tbeir importance as pre 0.6 ha swede field surrounded by potatoes, bar dators may be f90re doubtful (Geiler 1959/60, ley, meadow, gravel roads and mixed forests.
