Rezumat:

We have examined the community structure indices (species richness, dominance, diversity and similarity) of the rove beetles (Staphylinidae) assemblages in three differently treated apple orchards in Hungary.During the survey, a total number of 728 specimens belonging to 73 species were collected with pitfall traps. The dominant species were Omalium caesum, Drusilla canaliculata, Dexiogyia corticina, Mocyta orbata and Styloxys insecatus .Out of the differently treated orchards, the staphylinid abundance was the higher in the abandoned than in the conventionally treated and in integrated pest management orchards.The diversity profile of the communities showed that there were no differences between the diversity of the conventionally treated and abandoned orchards, and both were significantly more diverse than the IPM orchard. The similarity indices indicated that the forming dominance of the species was also influenced by the treatment. The distribution of the dominant species in each pitfall trap used in each plot shows the insecticide tolerance of the species
