In our country, based on data provided by Rogojanu Victor and Perju Theodosius (1979), andalso by Cornelia Tănasă-Catalina Ungureanu, Constantin Filipescu (2006), the main apple pests belongto the class Insecta, orders: Homoptera, Coleoptera, Lepidoptera, Heteroptera, Hymenoptera etc. andsome species belonging to the class Arachnida, order Acari. The purpose of these studies was to identifyharmful entomofauna to several apple orchards in Timis County.The knowledge of the structure anddynamics of entomofauna to apple is a very important element in establishing the foundations/bases ofbiological, ecological and economic forecast pest spread and development, for planning an effective plantprotection in the context of environmental protection. Monitoring the entomofauna in apple orchardsfrom Sag-Padureni and Lovrin, Timis County, was made between 2010 - 2011, the regular collection ofplant/vegetal material (leaves, branches, fruits) and frappage to determine homopteres and mites, shakethe tilt in the opening phenophase of floral buds, and use rub trap to determine harmful beetles bygathering with standard net or gluey traps to capture lepidopteran species. Determination and materialconservation were made due to the usual methodology and the determinations were made using thecurrent bibliography. Sampling was randomized on medium 30 trees, from May to September of eachyear. Following the research on harmful entomofauna composition on apple orchards under theconditions from Sag-Padureni, Timis County, it results that homopteres and heteropterys had the largestshare.From apple pests, were dominant Eriosoma lanigerum. Hausm., Aphis trees Geer., Psylla mali andHoplocampa testudinata Klug. As a result of the monitoring of the apple trees in orchard from Lovrinstood out as the dominant species of the orders Homoptera and Lepidoptera. These orders wererepresentative by species such as Eriosoma lanigerum Hausm., Quadraspidiotus perniciosus Comst. andLaspeyresia pomonella L.
