Abstract. The paper is related to plant-pest-entomophag interactions in cereal agroecosystem of Agricultural Research-Development Station Turda, in Transylvania. Under the conditions of actual agro-ecological changes, yielded by climatic warming and dryness and new technological and economical conditions of zone agricultural exploitations, the research points out the extension risk of cereal pests attack with an increasing potential and the importance of the elaboration of integrated control strategy (ICS). The attack diminishing recommended methods of the ICS are agro-technical methods; pests, diseases, weeds integrated control; insecticides treatments; conservation and use of entomophagous limiters.
