Increase agricultural output is conditioned by a number of factors, among which the protection of plants against pests plays a very important role. Along with chemical methods, methods of biological and integrated control against harmful organisms in crops have recently taken on a large scale, and one of these methods is the use of entomophages (predators and parasites). In order to identify and monitor species of entomophagous arthropods from the winter wheat culture, in the years 2016, 2017, an experiment was carried out in two locations in the center of Transylvania, namely in Turda in open field agroecosystem and in Bolduţ, in agroecosystem with protective agroforestry curtains. The field results were calculated and interpreted using ecological indices (abundance, dominance, constancy, and W ecology significance index). In addition to the monitoring of the entomophages, production and some of its components were determined. Entomophagous arthropods identified in the two agroecosystems differ only in ecological indicators, belonging to the same groups of entomophagous. The positive role of the agroforestry curtains in Bolduţ reflected both on the abundance of entomophages and wheat production, obtaind an 8% production increase compared to the production made in the unprotected system in Turda.
