Occurrence and fauna composition of gruond beetles in wheat fields

Abstract

According to this research, among the collected Coleoptera the most numerous were the epigeobiotic species of the families Carabidae, Silphidae, Staphilinidae, Curculionidae, Scarabaeidae and Chrysomelidae. Based on the number of individuals and the percentage of encounters in the studied areas, the Carabidae stand out in comparison to the other Coleoptera which is proved by the qualitative and quantitative composition of the collected fauna (36 species and 7,768 individuals). The representatives of the family Carabidae are of certain economic significance as well. Within this family the dominant and subdominant species in 2006 year were Agonum (Anchomenus) dorsalis (Ponto ppidan,1763) and Pterostichus (Poecilus) cupreus (Linnaeus, 1758) and in 2007, besides those, the same quantitative category also comprised the species Stomis pumicatus (Panzer,1795), Trechus quadristriatus (4-stiatus) (Schrank, 1781), Harpalus (Pseudoophonus) rufipes (De Geer, 1774) and Harpalus distinguendus (Duftschmid, 1812).
