Thus, massive attacks at the trees‟feet were observed <strong>in</strong> different arboreta. This phenomenon will largely spreadunless urgent measures for eradicat<strong>in</strong>g the pest hole are undertaken. This iswhy we have decided to <strong>in</strong>vestigate the parasitoid populations for Pityogeneschalcographus <strong>in</strong> the protected environment. In 2011 the most numerousspecies were: Nemosoma elongatum, Rhizophagus cribratus, Rhizophagusdepressus, Thanasimus formicarius, Quedius plagiatus, Quedius lateralis,Quedius cruentus, Quedius xanthopus.Key wordsPityogenes chalcographus,predators, Natural ParkApuseniParasitoids of Ips typographus (Coleoptera: Scolytidae) <strong>in</strong> theNatural Park ApuseniFora, C.G. 1* , Lauer, K.F. 2 , Banu, C. 1 , Berar, C. 11 Banat University of Agricultural Sciences <strong>and</strong> Veter<strong>in</strong>ary Medic<strong>in</strong>e <strong>from</strong> Timisoara; 2 University of AppliedSciences Weihenstephan-Triesdorf* Correspond<strong>in</strong>g author.
