All spruce forests are of the artificial origin and have recently been stressed by drought and honey fungus in hills (HOLUŠA, LIŠKA 2002).…”

A study of diprionids associated with spruce was done at 31 sites of the eastern part of the Czech Republic in 1988–2003. In total 45 specimens belonging to Gilpinia abieticola (6 specimens), G. hercyniae (3) and G. polytoma (36) were collected using Malaise traps, emergency traps, bark-beetle pheromone baited traps or sweeping. The spruce diprionids were recorded in 30% of the studied sites only. G. polytoma was the most abundant and it is probably bivoltine with adult activity from April to August. The results of emergence trap-monitoring in Paskovský les indicate that this species is in latency.

KivonatKutatásunk célja a fehér fagyöngy (Viscum album) fertőzés erősségének, illetve a potenciális gazdafajainak fiziológiai és biomechanikai vitalitása közötti kapcsolat vizsgálata. A vizsgálathoz összesen 9 gazdafaj (Acer campestre, A. platanoides, A. pseudoplatanus, Crataegus monogyna, C. pedicellata, Juglans nigra, Robinia pseudoacacia, Tilia cordata és T. platyphyllos) 3039 egyedét használtuk fel, melyből 1424 példány volt fertőzött. A vizsgált gazdafajok a csehországi lednicei kastélyparkból kerültek ki. Az eredményeink alapján megállapítható, hogy viszonylag szoros kapcsolat áll fenn e három tényező között. A leggyengébb kapcsolatot a mezei juhar (12-17 %), a legszorosabb kapcsolatot pedig a fekete dió (32-39 %) gazdafajok esetén észleltünk, azonban eredményeink ellenére továbbra is tisztázatlan maradt a fa életere-jének befolyásoló szerepe a fehér fagyöngy-fertőzésben.Kulcsszavak: fehér fagyöngy, Viscum album, gazdanövény, gazdafa fiziológiai és biomechanikai vitalitása, félparazita növény THE IMPACT OF THE EUROPEAN MISTLETOE (VISCUM ALBUM L.) ON WOODY HOST-PLANTS: A STUDY OF THE RELATIONSHIP BETWEEN INFECTION INTENSITY AND TREE VITALITY AbstractOur research aims were to examine the relationship between infection intensity of European mistletoe (Viscum album) and the physiological and biomechanical vitality of the potential host species. For this study 3039 individuals of nine host species (Acer campestre, A. platanoides, A. pseudoplatanus, Crataegus monogyna, C. pedicellata, Juglans nigra, Robinia pseudoacacia, Tilia cordata and T. platyphyllos) were examined; of these 1424 specimens were infected. The host trees are situated in the Castle Park in Lednice, Czech Republic. Based on our results, it can be concluded that there is a strong relationship between these three factors. The weakest relationship was observed in the case of field maple (12-17 %) and the strongest relationship was in the case of the black walnut (32-39 %). In spite of our findings, the exact role of tree vitality influencing mistletoe infection remains unclear.Keywords: European mistletoe, Viscum album, host tree, physiological and biomechanical aspect of vitality of host tree, hemiparasitic plant

Taxocenosis of psocids (Psocoptera) was studied in the territory of the Drahanská vrchovina Hills in the Czech Republic. Representative research plots were selected in forest ecosystems with natural species composition and spatial structure (small-scale strictly protected areas) as well as in forest ecosystems with altered tree species composition and spatial structure. So far the animal component has been paid insufficient attention in the studies of forest ecosystems, with just a few exceptions. As pointed out by Holuša (2003a), studying animals and their communities faces numerous obstacles caused for example by the hidden way of the life of certain species, complexity of obtaining the study material, complicated, time-consuming and technically demanding determination and often incomplete knowledge of the autecology of some species. The purpose of studying animals is to find regularities in their species composition within ecosystems as well as direct and indirect relations between the animal and the plant component of the studied ecosystem. In natural ecosystems, plant and animal components are dynamically balanced (Míchal 1994).In history, the animal component of ecosystems was studied in various units of the differentiation of natural conditions, from altitudinal vegetation zones (AVZs) to forest site type classification units of forest site type complexes (FSCs) or biogeocene type groups of the geobiocenological system. In the context of altitudinal vegetation zones, the existence of relations between numerous groups of invertebrates and selected vertebrate groups was investigated. Stolina (1959) studied gradations of Zeiraphera diniana and Choristoneura muriana, or Ips typographus within AVZ. Králíček and Po-
