Monitoring the biological supply of nine orchard mite species with special economical importance in middle Transylvania, was the aim of our paper. Besides usually monitored species (Quadraspidiotus perniciosus, Anthomus pomorum, Hoplocampa testudinea, Hoplocampa minuta, Cydia pomonella, Cydia funebrana şi Rhagoletis cerasi), other two were also considered (Janus compressus şi Eurytoma schreineri) because in last years were identified within tree plantations, and their population is in continuous increase and in several plantations became key mites. The classical monitoring method was used. The monitoring activity revealed the presence of the Quadraspidiotus perniciosus, phytosanitary quarantine specie was encountered in more than 80% of tree plantations, but biological supply was maintained on marginal rows or points difficult to access for chemical works. Paper originality consists in emphasizing the presence of Janus compressus in apple and pear trees and Eurytoma schreineri in plum tree. The practical aspects revealed by this paper underline the importance of this kind of approach for the warning campaign against orchard mites and performing chemical treatments .
