Knowledge about phytoseiid species associated with vines is a preliminary step in the development and implementation of integrated management strategies against phytophagous mites such as Panonychus ulmi. The aim of this study was to perform a comparative survey of phytoseiids present in abandoned, organically managed, and conventionally managed vineyards, as well as to compare ecological indices in these production systems. Samplings were conducted between July and September 2017 in vineyards situated in the Subregions of Lima and Cávado, the Vinho Verde region. A total of 50 leaves/vineyard were collected from 12 vineyards, kept in containers at low temperature and taken to Escola Superior Agrária-Instituto Politécnico Viana do Castelo to be screened under a stereoscope microscope. A total of 3.153 phytoseiid mites were sampled, belonging to eight species distributed across the vineyards analyzed. The most common species were Typhlodromus (Typhlodromus. pyri (45.7%), Kampimodromus aberrans (39%), and Phytoseius macropilis (8.7%). Higher richness occurred in abandoned vineyards, with seven species, and the most abundant were K. aberrans (46.5%) and T. (T.. pyri (28.9%). Only two predatory species were present (in similar proportions) in organically managed vineyards, T. (T.. pyri and K. aberrans, while T. (T.. pyri predominated in conventionally managed vineyards (93.8%). Kampimodromus aberrans. P. macropilis, and T. (T.. pyri were eudominant in abandoned vineyards while K. aberrans and T. (T.. pyri were eudominant in organic vineyards. Typhlodromus (T.. pyri was eudominant and T. (T.. exhilaratus was dominant in conventionally managed vineyards. Therefore, we might conclude that phytoseiid abundance significantly differs among vineyard management types, with higher ecological indices in abandoned vineyards, and lower indices in conventional managed vineyards in the northern region of Portugal.
