The species richness and composition ofAuchenorrhyncha assemblages in three apple orchards in Kent and East Sussex, England was surveyed in 2001 and 2002. Planthoppers, leafhoppers and froghoppers were collected from the tree canopies using yellow sticky traps and a tree beating technique, and from the grass alleyways between the trees using sweep-netting. As a result of intensive sampling, 67 species were collected in an experimental apple orchard at East Malling Research, with a further 30 and 36 species in two organic apple orchards, situated near Marden and Robertsbridge, respectively. A total of 77 species was recorded in the survey. The collection methods applied determined substantially the size and species composition of the samples, the relative abundance of the Auchenorrhyncha species and proportion of males. The most common species collected in the canopy, in decreasing order were: Edwardsiana rosae, Empoasca decipiens, Ribautiana debilis, Edwardsiana crataegi, Empoasca vitis, Philaenus spumarius and Tachycixius pilosus .

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.
