Species richness and composition of Staphylinidae communities were investigated at ground level when differently treated with pesticides and in abandoned apple and pear orchards in Hungary. Altogether 6099 individuals were collected belonging to 241 staphylinid species. 233 have been identified to species level and 8 staphylinid taxa were determined up to generic level. More than 20% of the Hungarian staphylinid fauna was represented in the orchards. The similarity (Jaccard index) between apple and pear orchards at ground level were 54%. The species richness in each orchard varied between 23 and 100 species. The most widely occurring species in orchard ground level were: Dinaraea angustula, Palporus nitidulus, Tachyporus hypnorum, Sphenoma abdominale, Omalium caesum, Philonthus carbonarius, Drusilla canaliculata, Sepedophilus marshami, Mocyta orbata, Coprochara bipustulata, Mocyta fungi, Hyponygrus angustatus, Purrolinus laeticeps, Paraphallus linearis, Omalium cursor, Heterothops dissimilis and Atheta crassicornis.
Community structure (species richness, dominance, similarity, diversity and seasonal dynamics) of the rove beetles (Staphylinidae) was examined in an abandoned, a conventional and an organic vineyard management plot of an experimental vineyard in Hungary.During the survey, a total number of 493 specimens belonging to 33 species were collected by pitfall traps. The dominant species were Sphenoma togata, Xantholinus linearis and Pseudocypus penetrans that presented 76.66% of all staphylinids collected in the vineyard. All of the most common staphylinid species had only one generation per year and overwintered as adults.There were significant differences in species richness and abundance; both were the highest in the abandoned plot. The dissimilarity in species composition between the differently treated plots was also high. The diversity was the highest in organic, and the lowest in conventionally treated plot, while the abandoned one showed an intermediate value.
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
