LONGICORNES OF BAKONY MOUNTAINS This English summary helps to understand our book illustrated by the author's photos about Cerambycidae of Bakony Mountains. More than 9000 collecting data , altogether 169 different species with their ways of life, spreading, ecology and foodplants are described and are showed in 7 tables. Geographical description Bakony is the largest range of mountains in Hungary. It is situated in the middle of Transdanubia, on the north of Lake Balaton. Its total extension is about 4000 square kilometres, its altitude is 200-700 ms. Its principal mass is dolomite and limestone. Special character of B Q akony is given by thermophyl and xerophyl plants. The average annual temperature is about 9.0-9.5 C, the annual precipitation is 600-800 mms. Bakony has only a few brooks and ponds. Spreading of the different species of trees can be seen in Table 1. The fauna territory "Bakonyicum" comprises five faunal subdistricts, on the basis of zoogeographical investigations (PAPP 1968). They are as follows (see Map 1.): I. Balaton-Highland This area is not too high, but it is very warm, with submediterranian character. Mainly warm-liking oak forests can be found here, but large cultivated areas also occur. II. Keszthely-Mountains The northern part of these mountains is influenced by the atlantic climate. Oak forests are prevailing. III. South-Bakony Its climate is a transition between that of the Balaton-Highland and that of the Nort-Bakony. IV. North-Bakony The atlantic climate has the most significant influence here. There are the highest tops on this area (Kőrishegy 709 ms and Kék-hegy 669 ms). Its characteristic forest is submontan beech forest. Bakonyalja is situated on the north-western part, the natural pine forest of Fenyőfő belongs to this area. V. East-Bakony This part is influenced by the continental climate to most intent. About longicornes in general Longicornes (Cerambycidae) belong to Coleoptera. They have long feelers and capacity to give sounds. Longicornes have sexdimorphysm: feelers of the males are longer than those of the females. I rewiew the morphology and way of life of these beetles, their grubs and pupae. I touch upon the agricultural importance of Cerambicidae as well. About the research of the Cerambycidae-fauna The zoogeographical investigation of Bakony is organised by the Museum of Natural History of Bakony (BTM) in Zirc. Nowadays the successful! collecting is possibile only by specialists. Albeit many specialists collect longicornes in Bakony, any monographies has not been published so far. I could write this monography by the help of about 20 Cerambycidae-specialists. I should like to express my thanks to them here. I give their addresses where their collections can be found. I write where they have collected most often. Although I observed many new species in Bakony, there are still possibilities to investigate Cerambycidae. About the method of collecting One-by-one is the oldest and the most simple method. Nocturnal species can be collected by turning the tree-trunks and by peeling off the barks, too. We got our data mainly in spring by these methods. They would be more correct in respect of foodplants and way of life if we netted only one sort of plants or we made a brush-wood pile from one sort of trees. The trapping by different methods is not too successful, because longicornes have no capacity to fly or to run for a longer distance. Recently the most successfull method is to breed the grubs or pupae on their foodplants. This method gives the most correct information. Storing of wood is not simple, that is why only few specialits do this. We can often get rare longicornes in great numbers as well. We can get the best results when grubs are collected with their cradle, but we must not be too curious, because imagos peeped previously often hatch
