Summary

A contribution to the morphology and biology of Hylecoetus dermestoides L.

At first the occurence ofHylecoetus dermestoides L. in the Austrian forests near Aflenz and Rosaliengebirge is described. Analyses of beech stumps are carried out. In general, beech stumps and beech stems are covered with eggs not earlier than one year after felling. The mechanical devices for timber processing such as chitin saws of the larvas and their function is throroughly described. It was found, that the chitin saws are accomodated to the steadely changing timber resistance of the canal walls due to timber decomposition byAmbrosia-mushrooms which are cultivated by the larvas.
