FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LIX 1998 pp. 35-52 Data to the Heteroptera fauna of the Bükk Mts N Hungary M. Földessy Data to the Heteroptera fauna of the Bükk Mts N Hungary - Contribution to the knowledge of the Heteroptera fauna of the Bükk Mountains. So far unpublished distributional data of 159 Heteroptera species collected from 111 localités of the Bükk Mts (N Hungary) are given by the autor. Large part of the territory is National Park. Data published in this study represent approximately 110 years of collecting activity. These serve firm basis for the forthcoming diversity examinations. Heteropterological collectings were carried out for more than 110 years in the Bükk Mts. Results of these have never been summarized, only details or data of certain territories have been published. Recently the works of Bakonyi and Vásárhelyi (1993), Kondorosy and Kis (1996) dealing with the Naucoridae, Nepidae, Gerridae and Lygaidae families were issued. The studies of Földessy and Varga (1995) and Földessy (1988) contain the results of special examinations. In the last few years the significance of entomological examinations of certain geographical units or their plant associations is increasing. Its importance is stressed by the comming of the National Biodiversity Monitoring Programme. We can assume that in the course of this programme special attention will be paid to the examination of plant associations and zoocoenoses of the Bükk Mts being the most diversified part of the country from geological point of view. Main basic rocks are Paleozoic shales and Mezozoic (Triassic) limestones. Igneous rocks and dolomites also occur locally. At the edge of the mountain we can find Cenozoic sediments in great variety (eg.: Tard Clay, Kiscell Clay, different calcareous tuffs). These diversified sediments made possible the formation of the unique morphology of the Bükk Mts (deep canyons, steep cliffs, highlands karstic phenomena), by which the flora of the territory is basicly determined. As external ecological element the morphology and the vegetation assure the high diversity of the fauna. In the course of the heteropterological exanimations there have been collected plant bug species occurring at the representatives of the various plant associations. These species represent - since 1885 until nowadays - the presence and distribution of Heteropteras as it is shown by the enclosed map and table. The above-mentioned facts justify the necessity of a general study attempting to build up a standard database using materials of different collectors and collections. The origin of data is as follows: Heteroptera collections of the Hungarian Natural History Museum, Entomological collection of the Mátra Museum, Eszterházy Károly Teachers' Training College, Department of Zoology (see map). Exact geographical determinations of the localities according to the collective cards, have also been done because these were not unified in early collectings. I carried out
