The thesis deals with determination of species spectrum of the pathogens which infest bark beetle Dendroctonus micans. The aim of the thesis was to determinate species spectrum of the pathogens in the tract of the bark beetles D. micans. Specimens were obtained from Liptovský Hrádok in Slovakia. Collection of the specimens took place on four localities in the April in the year 2015. The specimens were storage in freezer at -17°C. In total 154 bark beetle were dissected. Female beetles were more frequent than male beetle. Female beetles were 123 and male only 8 at 23 sample were not possible to determine sex gender of beetles. After dissection of all specimens, was discovered in 88 cases only one pathogen, intestinal Nematoda. Any other pathogen was not discovered. The other benefit of the thesis was ecplored the speculation of possibility to use pathogens effectively and safe in biological fight againts D. micans.
