Sažetak
Pityokteines spinidens is the most abundant and most important pest species on Silver fir in Croatia. Due to a lack of knowledge about the potentials of their natural enemies, emerging beetles from incubated stem sections were examined for phoretic mites and pathogenes. A total of 8 mite species was documented as associates of P. spinidens of which Ereynetes scutulis could have some potential for biological control. The fungus Beauveria bassiana is a common pathogen of bark beetles and was often found in breeding galleries of P. spinidens (13% mortality). Furthermore, three microsporidia and one gregarinan species were observed: Canningia spinidentis, Menzbieria sp., Chytridiopsis cf. typographi and Gregarina sp. Data presented in this study show possible candidates for further tests to utilize pathogens as microbial control agents against fir bark beetles in the future.
