DATA OF SOME ORDERS OF INSECTA OCCURING IN BAKONY MOUNTAIN In this work the author treats the occurence of Ephemeroptera, Plecoptera, Neuroptera, Raphidioptera and Trichoptera collected by the workers of the Museum of Natural History in Zirc, by László Rézbányai and some other collectors in the Bakony mountain. Very few pieces of information have been known about the above-mentioned orders of this region. Surveying the data of occurence it is striking that the number of species and specimens of Ephemeroptera and Plecoptera is here less compared with the other mountain of Hungary. According to the author the reasonfor that the level of water descended in the last three or four decades on account of the consumtion of water by the new towns and industrial establishements built on the edge of the mountain. The stream of the fountains and brooks decreased, some of the fountains ceased flowing, so with less stream the temperature of water rose, the content of oxigen diminished and the conditions of life for Ephereroptera and Plecoptera became unfavourable. An other disadvatageous effect is the expanding pollution of the remained waters. Among the collected insects the following seven are new for the Hungarian faunaUeptagenia affinis Etn., Isoptena serricornis Pict, Coniopteryx pygmaea Ender.,Conwentzia psociformis Curt Aleuropteryx loewi Klap. Rhyacophila pascoi Mc Lach, and Limnephilus centralis Curtl The abbreviations of the often occuring collectors' names can be found at the end of the Hungarian text.
