Eight bark beetle species (Coleoptera:Scolytidae) were recovered from trap log sections in a coniferous forest in the Central Alps of Austria. One to four different pathogen species (mainly microsporidia) were found in all these coleopteran species. Several bark beetle species were found infected by three pathogen species. Differences were observed in infection rates comparing male and female beetles as well as comparing parental and offspring beetles. In addition, differences were found in occurrence and in abundance of pathogens in beetles emerging from loga sections of the first trap log series in comparison with those emerging from sections of the second trap log series resp. from branches.
