Sažetak
Occurrence of the entpomopathogenic fungi Beauveria bassiana and their influence in the reduction of Pityokteines fir bar beetle population was studied at two localities in Croatia. The mortality of bark beetles at the location Trakošćan was 60-73% while 41-45% at Litorić. The mortality rate caused by the fungi B. bassiana in Trakošćan was between 11,6 and 25,2%, and in Litorić between 1,7% and 13,2%. The aim of this study was to obtain first information about the fungi B. bassiana in fir bark beetle population in Croatia and build a basis for future research of fungi isolates which can be used in biological control measures against fir bark beetles.
