148 DUNÁNTÚLI DOLGOZATOK (A) TERMÉSZETTUDOMÁNYI SOROZAT 10. (2000) Fig. 1. Map of the Villány Hills with the location of the 15 sampling sites investigated by NAGY, A. The most important habitats for the Orthoptera species are on the southern slopes. The steep slopes built of limestone and dolomite are covered by open rocky grassland (Sedo sopianae-Festucetum dalmaticae). The Chysopogono-Festucetum dalmaticae association is situated on less steep dolomite slopes of the Tenkes and the Csukma. These rocky grasslands are often mixed with shrubs. Inulo spiraeifoliae-Brometum pannoniéi rocky grassland can be found only on the top of the Szársomlyó in northern exposure (DÉNES 1998). Steppe grassland (Cleistogeni-Festucetum rupicolae) is situated on the hillfoots and plateaus on loessy soil. The southern slope of the Szársomlyó is partly covered by karst shrubforest {Inulo spiraeifoliae-Quercetum pubescentis) that is mixed with rocky grassland. The closed plant association of the southern slope of the Fekete Hill, the Tenkes and the Csukma is oak forest (Ото- Quercetum pubescentis). Shrubforest can be found also on the Fekete Hill (DÉNES 1995). It is worth mentioned that the most of this area have been planted by vineyards for centuries. The collector works had two main sources. There were several occasional samplings trough the years mentioned in the Introduction, which resulted in some valuable faunistical data. Systematic samplings were made on the Szársomlyó by J. MAJER in 1988 (unpublished) and mostly by the first author of this paper in 1997-1998 (NAGY, A. 1999) and 1999-2000. Samplings were made predominantly by sweep-netting supplemented by capturing single specimens. We followed HARZ (1969, 1975) for identification and HELLER et al. (1998) for nomenclature. In order to defend the populations the living specimens collected especially in the last years were released at site after the identification. The collected material was investigated on various ways according to the researchers. Larvae collected in the early season (April, May) were reared up to imagoes in order to make determination easier and more certain. The dried (prepared and pined) and wet materials are preserved partly at the Plant Protection Institute (Budapest) and partly at the Department of Zoology and Human Biology (University of Debrecen).
