Species richness and composition of carabid assemblages were investigated on the ground surface of differently treated (abandoned, commercial and IPM) apple and pear orchards in Hungary. Extensive sampling was carried out by pitfall trapping in 13 apple and 3 pear orchards located in ten different regions. 28 230 individuals belonging to 174 species were collected. Additional four species were collected by trunk-traps and 23 species were found during the review of earlier literature. Altogether 201 carabid species representing 40% of the carabid fauna of Hungary were found in our and earlier studies. The species richness varied between 23 and 76 in the different orchards, the average species richness was 43 species. The common species, occurring with high relative abundance in the individual orchards in decreasing order were: Pseudoophonus rufipes, Harpalus distinguendus, Harpalus tardus, Anisodactylus binotatus, Calathus fuscipes, Calathus erratus, Amara aenea, Harpalus affinis and Pterostichus melanarius. The species with wide distribution, occurring in more than 75% of the investigated orchards in decreasing order were: Pseudoophonus rufipes, Trechus quadristriatus, Harpalus tardus, Harpalus distinguendus, Pterostichus melanarius, Amara aenea, Amara familiaris Calathus fuscipes, Poecilus cupreus, Calathus ambiguus, Calathus melanocephalus, Pseudoophonus griseus and Harpalus serripes. Species, which are rare in Hungary, and therefore are interesting in respect of faunal research, were: Amara cursitans, Harpalus progrediens, Notiophilus pusillus, Olisthopus rotundatus, Pangus scaritides and Parophonus hirsutulus.

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.
