Sažetak
The abundance of ground beetles (Coleoptera, Carabidae) in oilseed rape field can be an important indicator of different agricultural measures in arable land fauna. Surveys about ground beetle fauna in Croatia are generally very scarce and only few researches on oilseed rape were conducted. The aim of this study was to gather information on endogaeic ground beetle species composition and to determine their synecological characteristics. The study was carried out on an oilseed rape field in western part of Croatia (Virovitica-Podravina County, village Lukač) from the end of May till mid- September in 2015. Ground beetles were collected in spring and autumn using endogaeic traps. Altogether, 487 individuals from 8 species belonging to 6 genera were collected. Most abundant species in both spring and autumn populations was Brachinus (Brachinus) psophia Audinet-Serville, 1821. In spring population, Anchomenus (Anchomenus) dorsalis (Pontoppidan, 1763), Brachinus (Brachynolomus) explodens Duftschmid, 1812 and Brachinus (Brachinus) psophia were eudominant, while Brachinus (Brachinus) psophia was constant species. In autumn population, eudominant species was Brachinus (Brachinus) psophia, while euconstant species were Anchomenus (Anchomenus) dorsalis and Brachinus (Brachinus) psophia. In spring population, the highest ecological significance index had species Brachinus (Brachinus) psophia followed by Anchomenus (Anchomenus) dorsalis and Stenolophus (Stenolophus) teutonus (Schrank, 1781). Species Brachinus (Brachinus) psophia had the highest ecological significance index within autumn population. Sörensen’s coefficient showed week overlapping (0.4%) of the spring and autumn populations. Shannon’s index confirmed spring population is more diverse (H= 1.898) in relation to autumn population (H= 0.161). This study represents a valuable contribution to the knowledge of endogaeic ground beetle fauna in oilseed rape fields in Croatia.
