The species diversity, aktivity, equitability and human impact were studied using epigeic beetle communities on transect whest field field trip and alfaalfa field. The materiál was collected by pitfall traps during the period Juni-September 20016 in cadastr of the town Písek in the Southern Bohemia. 38 species and 567 individuals were kept together. Activita of beetles differs in studied plots. The highest aktivity was found on fields and the lowest in field trip. Index of human impact was very similar on studied plots wheat 2,5, field trip 12, rape 0). I tis clear that alll studied are strongly impacted by human acticity. The frequency of relic species were (Dragons and Ground beetles) 20% only on all studied plots 80,00%. The adaptible species absent on field cultures and was found on field trip only. 6 species of adaptible (stenotopic) species were found on field trip only, but their aktivity were very low. The equitability of communities in filed plots was very low (2,331 2,474). The highest equitabilty was found on field trip (3,04). The ordination of commuties indicate the close similarity. The species diversaity is very similar in all communities on studied plots. We recommend the change of sowing management and the lower agrotechnic interference in studied locality. We recommend to enhance the plots of biocorridors and biocenters. The stuided field trip plays a role for the increse of the biodiversity of epigeic beetles, which are important for the reduction of pest organisms in agricultural landscape.
