Description

In order to study species diversity and population interactions, vineyard, weed vegetation and mite population were surveyed. This research was carried monthly from April to December 2004, in two vineyards located in the Setúbal region, with different soils and climate conditions. A total of 167 weed taxa were identified belonging to 42 botanical families. Asteraceae, Fabaceae and Poaceae showed the greatest number of species. Considering the species with a relative higher frequency, the more abundant were Calendula arvensis, Convolvulus arvensis, Cynodon dactylon, Lavatera cretica and Parietaria judaica, in the vineyard of Quinta de Camarate, and Convolvulus arvensis, Cynodon dactylon and Panicum repens, in Quinta do Anjo. In vines 12 mite species were identified, the dominants were the phytophagous Calepitrimerus vitis and the predators Typhlodromus pyri, Typhlodromus phialatus and Homeopronematus anconai. In ground cover were identified 32 mite species, tetranychids and phytoseiids were the predominant mites, especially Tetranychus cinnabarinus, the most polyphagous species, detected in 37 weeds, and Typhlodromus pyri, the predominant phytoseiid, found in vines and cover vegetation, being present in 22 weeds. From acarological point of view, weeds can be considered useful in vineyards, safeguarding Tetranychus urticae hosts and that there may be competition to the crop.
