Abstract
Four different pathogen species (Gregarina typographi, Chytridiopsis typographi, Unikaryon montanum and Menzbieria chalcographi) were found in adult Ips typographus from the Forest Demonstration Centre, BOKU University in the course of a 7-year period of investigation (1995–2001). Annual variations were found in both the spectrum and prevalence of pathogen species. Variations were found in the number of infected male and female beetles as well as the infections of beetles with different dates of emergence.
