Among the abovementioned parasitoids, the species Rhaphitelus maculatus had greatest influence on Scolytus rugulosus abundance. It was identified in 73.7% of examined samples, its average domination was 53.7% and average percent of Scilytus rugulosus parasitism was 23.9%. Besides, the species Ecphylus silesiacus, Cheiropachus quadrum, Entedon ergias and Eurytoma morio had a strong effect on Scolytus rugulosus abundance. The significance of other parasitoids was low. Parasitoids have a great influence on the abundance of Scolytus rugulosus because they reduce the abundance of their host 44.5% on average.
