  Species composition of carabid (Coleoptera Carabidae) communities in apple orchards and vineyards in Val d’Agri (Basilicata, Italy)

  ABSTRACT
  An entomological investigation was carried out in an agricultural area, mainly apple orchards, of the Agri river plain, located in some municipalities of Basilicata, Italy. Between 2012 and 2014, species richness and composition of carabid assemblages were investigated on the ground surface of differently managed (abandoned, organic, commercial and IPM) apple orchards and vineyards. Ground beetles (Coleoptera Carabidae) were sampled by means of pitfall traps. 1288 individuals belonging to 40 species were collected, representing two-thirds of the carabid fauna of this area found in our and earlier studies. The species richness varied between 4 and 20 in the different orchards. The common species, occurring with high relative abundance in the individual orchards in decreasing order were: Pterostichus (Feronidius) melas (Creutzer, 1799), Pseudoophonus (Pseudoophonus) rufipes (De Geer, 1774), Brachinus crepitans (Linnaeus, 1758), Harpalus (Harpalus) dimidiatus (P. Rossi, 1790) and Poecilus (Poecilus) cupreus (Linnaeus, 1758). Most of the collected ground beetles were species with a wide distribution in the Paleartic region, eurytopic and common in European agroecosystems. The assemblages were dominated by small-medium, macropterous species, with summer larvae. No endemic species were found.
