At permanently established sample plots examinations were conducted to assess chlorosis, defoliation and damages caused by the gypsy moth and powdery mildew instigators. The aim of this paper was to perform preliminary examinations and determine whether there is any connenction between the magnitude of the mildew infections and that of the gypsy moth attacks on Hungarian oak, Turkey oak and Sessile oak trees in the territory of Serbia and whether there are differences in attacks among the three oak species. The largest number of defoliated Sessile oak trees with severe chlorosis were recorded during the year 2005, which was followed by the strongest attacks of the powdery mildew and gypsy moth on the same species. Izvod: Ispitivanja u ovom radu su vršena na 3 područja u Republici Srbiji - Kragujevac, Požarevac i Vrnjačka Banja, na kojima se zonalno nalaze veće površine pod hrastovim sastojinama (najčešće vrste hrastova na ovim područjima su Quercus farnetto, Q. cerris i Q. petraea). Pregledi su rađeni na stalnim bioindikacijskim tačkama, na kojima je vršena ocean hloroze, sušenja i evidentirana oštećenja od gubara i prouzrokovaća pepelnice. Cilj ovog rada je bio da se izvrše preliminarna ispitivanja i utvrdi da li postoji veza između intenziteta zaraze pepelnicom i jačine napada gubara i na sladunu, ceru i kitnjaku na području Srbije i da li postoji razlika u napadu na ove tri vrste hrastova. Najviše suvih stabala kitnjaka i stabala sa jakom hlorozom bilo je tokom 2005. godine, što je bilo praćeno i najjačim napadom pepelnice i gubara na ovoj vrsti. info:eu-repo/semantics/article All rights reserved Key words: Turkey oak, Hungarian oak, Sessile oak, Gypsy moth, Powdery mildew Ključne reči: cer, sladun, kitnjak, gubar, pepelnica eng srp
