Oriental beech is the economically most important tree species of Iranian productive forests. Until now some 43 insect species are related to Oriental beech as a host tree in Iran, the majority not being very host specific bark and wood borers. Impact, damage and losses with regard to silvicultural treatment and wood utilization of beech in Iran, that are or can be clearly related to insects, is remarkably low. It is looked at the preserved natural state and structure of this forest type and the applied exploitation practices, to explain this. However, knowledge on local development and behaviour patterns of the insects concerned is not yet complete and the present opinion might change as a result of further detailed studies into interrelationships with other sources of forest damage. At the same time may the introduction of intensive management practices, under way at present, bring about an essential change of knowledge of the role some of these insects will play in future. Close observation of all changes from the point of view of forest entomology is necessary. Zusammenfassung Schädliche Insekten der Orientbuche (Fagus orientalis ssp. macrophylla) im Iran und ihre forstwirtschaftliche Bedeutung Die Orientbuche ist die forstwirtschaftlich wichtigste Holzart im Iran. Bislang wurden 43 schädliche Insektenarten an und in dieser Buchenart gefunden, worunter die wichtigsten unspezifische Borken‐ und Bockkäfer sind. Über Befall, Schadwirkungen und Verluste durch Schadinsekten an Orientbuche wissen wir z. Z. noch sehr wenig. Die Kenntnise über die Abwehrkräfte der Buche sowie über das Verhalten der schädlichen Insekten müssen auf Grund detaillierter Studien verbreitert und intensiviert werden, wobei die gegenwärtig entwickelten neuen Methoden der intensiven Forstnutzung mit zu berücksichtigen sind.
