The negative evolution of Romanian Quercinae forests health state, needs a careful analysis of the managing methods of these forestry ecosystems, in terms of disease and pests control and management measures. In this paper is presented the prognosis for the year 2015, ofLymantria disappeardefoliator evolution, present in the northwestern Transylvanian oak forests. The reports concerning theLymantria dispardefoliator are being done in all developmental stages of the insect and the detection of infested surfaces is done  after the eggs are depositited in September - October. All analysis performed  upon the samples taken from the three Forestry Departments and four Forestry Districts revealed that defoliator is in retrogradation, which corresponds to the situation in which all adjacent surfaces for analyzed samples will be included in 2015 in the surveillance zone.
