The importance of natural vegetation around crop fields is to be recognized as a reserve of entomophagous arthropod diversity. The objective is to know the composition of potential biological controllers of pests present in the edge vegetation of the Chrysanthemum crop in the Prepuna jujeña. The study was carried out on three fields, between October and December/17 and February/18. The arthropods were collected with Moericke traps, four in spontaneous vegetation (VE) and four in wind curtains (CV). A total of 1126 entomophagous arthropods were collected, 472 in VE and 654 in CV, distributed in 40 families. 897 parasitoids and 229 predators were identified. The most abundant and rich order was Hymenoptera (967/26). The most abundant parasitoid was Encyrtidae (28.6%) and among the predators, Anyphaenidae (5.5%). The results show the necessity to continue with studies on the importance of selecting edge plant species for the support of the beneficial entomofauna.
