Carabid beetles were collected by pitfall trapping from seven different horticultural and agricultural crops (apple, apricot, olive, peach, and walnut orchards, vineyards, and wheat fields) in Turkey. Data were obtained on the number of carabid species in Turkish agricultural landscapes and the Influence of habitat type on carabid activity and distribution. A total of 959 ground beetles representing 57 species were captured. Species diversity of individual sites ranged from five in a walnut plantation to 32 in an apple orchard. Species accretion models in two localities gave estimated overall carabid species richnesses or 22-26 species. Comparison of sites and years suggests that the carabid fauna may be determined more by geographic location and altitude than by crop type.
