Effects of farm practices and soil management on ground-dwelling arthropods fauna

Proučavanje entomofaune moglo bi pružiti uvid u funkcioniranje ekosustava ovisno o poljoprivrednoj praksi. Cilj ovog rada je bio istražiti brojnost, raznolikost i sastav faune prizemnih člankonožaca u vinogradima različitog načina gospodarenja tlom i proizvodnje u okolici Zadra. Istraživanje je provedeno u integriranom i konvencionalnim vinogradima. Uzorkovanje je provedeno lovnim posudama koje se ukopavaju u tlo (16 posuda po vinogradu). Uzorci su uzimani svakih 15 dana od početka svibnja do kraja listopada 2014. Pronađeno je sveukupno 469 jedinki razvrstanih unutar 7 redova i 24 porodice. Najbrojnija je porodica Formicidae unutar reda Hymenoptera (179), zatim red Coleoptera (150), te red Aranea (131). Najveća raznolikost i najveći broj jedinki (232) zabilježen je u integriranom vinogradu. Rezultati potvrđuju utjecaj načina proizvodnje i gospodarenja tlom na brojnost i raznolikost prizemnih člankonožaca.The study of entomofauna could provide information how ecosystems respond to different management practices. The aim of this paper was to assess abundance, richness and composition of epigeic arthropods according to menagement practices and ground cover in vineyards near Zadar. The research was carried out in one integrated and two conventional vineyards. In each vineyard 16 pitfall traps were placed. Samples were taken every fifteen days from the beginning of May till the end of October in 2014. A total of 469 individuals belonging to 7 orders and 24 families were collected. The most abundant taxonomic group was Hymenoptera - Formicidae (179), followed by Coleoptera (150) and Aranea (131). The highest number of specimens (232) were recorded in integrated vineyard. Our results confirmed the impact of soil management and type of production on arthropod abundance and diversity
