Forest management greatly affects the population density of the European spruce bark beetle, [Ips typographus]. In this study, a meta-analysis was used to determine whether infection levels of pathogens of [I. typographus] differ between managed and unmanaged spruce stands. The analysis used data from 10 publications and a total of 61 locations. The results indicated that infection levels of the most common pathogens (ItEPV, [Gregarina typographi], and [Mattesia schwenkei]) are higher in unmanaged than in managed locations. The only exception is the microsporidium [Chytridiopsis typographi], which is more common in managed than in unmanaged locations. Our meta-analysis indicates that pathogen levels are generally higher in unmanaged than in managed locations.
