Species richness and composition of cicada (Auchenorrhyncha) assemblages were investigated in apple and pear orchards subject to different pesticide management intensities (conventional commercial orchards with a full spray programme of fungicides and broad-spectrum insecticides, Integrated Pest Management, organic and abandoned orchards) in Hungary in 1999, 2000 and 2001. Sampling was done with Malaise traps, by sweep netting and beating nets in ten apple and three pear orchards in seven different regions of Hungary. Altogether 15 686 individuals were collected in the orchards investigated, belonging to 114 species, representing 20% of the cicada fauna of Hungary. The most common species, in decreasing order of relative abundance, were: Eupteryx atropunctata (Goeze), Empoasca solani (Curtis), Edwardsiana crataegi (Douglas), Kybos virgator (Ribaut), Empoasca decipiens Paoli, Zyginidia pullula (Boheman), Eupteryx calcarata Ossiannilsson, Kybos populi (Edwards), Psammotettix alienus (Dahlbom), Laodelphax striatellus (Fallén), Edwardsiana rosae (Linnaeus) and Ribautiana tenerrima (Herrich - Schäffer). The species which are rare in Hungary and therefore are interesting in respect of faunal research were: Enantiocephalus cornutus (Herrich - Schäffer), Rhoananus hypochlorus (Fieber), Metalimnus formosus (Boheman), Phlogotettix cyclops (Mulsant and Rey), Ossiannilssonola callosa (Then) and Mocuellus metrius (Flor). The mean proportion of males was 0.82 and 0.44 in the samples collected by Malaise trapping and sweep netting, respectively.
