Major knowledge gaps exist regarding effects of landscape-level agroecosystem composition on the presence of natural enemies of agricultural pests. The objective of this study was to evaluate the influence of landscape mosaic characteristics on the diversity of predators and parasitoids of a viticultural landscape in La Rioja, Spain. Five habitats were evaluated: Mediterranean forest, Mediterranean scrub, olive groves, natural grassland, and vineyards. In all, we collected 28,640 arthropods, representing 10 orders: Araneae, Coleoptera, Dermaptera, Diptera, Hemiptera, Hymenoptera, Mantodea, Neuroptera, Solifugae, and Thysanoptera. The grassland habitat presented the highest arthropod abundances. Carabid beetles showed preferences for Mediterranean forest and scrub, whereas reduviid bugs showed preferences for natural grassland. Landscape heterogeneity and connectivity with natural elements in the study area turn out to be effective in conservation of diversity of natural enemies of viticulture.
