Pest status of Dendroctonus micans (Kugelann) (Coleoptera: Scolytidae) and the effect of Rhizophagus grandis (Gyllenhal) (Coleoptera: Rhizophagidae) on the population of Dendroctonus micans in the oriental spruce forests of Turkey This study was conducted in oriental spruce forests in the Eastern Black Sea Region of Turkey where Dendroctonus micans (Kugelann) (Coleoptera: Scolytidae) and its specific predator, Rhizophagus grandis (Gyllenhal) (Coleoptera: Rhizophagidae), have been active for the last 20-30 and 10-15 years, respectively. A total of 1186 trees were examined in 33 different areas. Of these trees, 793 were spruce. D. micans damaged 24,6 % of spruce trees. Eighty eight percent of wounded trees was damaged by D. micans. A total of 540 D. micans adults were counted on 58 trees. 52,4 % of the adults were recorded on 3 trees in the same experimental plot. A total of 2905 larvae were counted on 41 trees in 20 experimental plots and 177 pupae were counted on 7 trees in 5 plots. Sixty point four percent of larvae was recorded on 10 trees in 4 experimental plots and 91,5 % of the pupae were recorded on 3 trees. A total of 384 R. grandis larvae and adults were recorded together with a total of 997 D. micans individuals in different developmental stages. The effectiveness of R. grandis on D. micans in the galleries, in the experimental plots and in whole area was 84 %, 24 % and 15 %, respectively
