AB  - In this study, <I>Ips sexdentatus</I> (Coleoptera: Curculionidae, Scolytinae) populations from Kastamonu (Turkey) were investigated for the occurrence of entomopathogens. Two species were encountered in the duration of this study and these were <I>Gregarina typographi </I>(Apicomplexa, Gregarinidae) and <I>Metschnikowia typographi</I> (Ascomycota, Metschnikowiaceae). Within the <I>I. sexdentatus </I>samples used in this study total infection rate of the pathogens <I>G. typographi</I> and <I>M. typographi</I> was calculated as 28.9%. Measurements of the <I>Metschnikowia</I> species identified from <I>I. sexdentatus</I> were as follows: mean length 16.86&plusmn;2.2 &#956;m and mean width 2.8&plusmn;0.3 &#956;m (n = 125). The ascospores of this pathogen were characteristically needle-shaped and therefore, easily distinguishable under the light microscope. The occurrence rate for the ascomycete pathogen (<I>M. typographi</I>) was 3.1%. The gregarine pathogen measured 108.1-203.5 &#956;m and was identified as <I>Gregarina typographi</I>. The occurrence rate for the Gregarine pathogen was 25.8%. The first report for Turkey (Kastamonu) of an ascomycete fungus, <I>Meschnikowia typographi</I> from the pine bark beetle <I>Ips sexdentatus</I> (Boerner) is given in this study.
