Abstract: The present study´s main objectives were the survey of acarological diversity and mite, strawberry and weed interactions. The study was performed on strawberry crop, „Splendor‟ and „Camarosa‟ cultivars, using the high tunnel and outdoor methods. Floristic and acarological surveys were carried out monthly, from December 2008 to July 2009, in the Ribatejo region. Thirty-three and 18 weed species were identified using the outdoor and the high tunnel method, respectively. Seven mite species were identified on the strawberries, being the most important the phytophagous Tetranychus cinnabarinus and the predaceous Amblyseius californicus, present in both strawberry cultivars and methods. From the 33 weed species identified, 19 were hosts of mites with agricultural interest. Tetranychids and phytoseiids were predominant, especially Tetranychus cinnabarinus, very polyphagous, found on 15 weed species, Phytoseiulus persimilis on seven and Amblyseius californicus on four. Tetranychus cinnabarinus and Amblyseius californicus were species also present in the crop. The most important host weeds of the phytophagous mites were Datura Stramonium, Lavatera cretica and Solanum nigrum. Tetranychus cinnabarinus was the most abundant and frequent tetranychid in the three plant species. Lavatera cretica was the most important host weed of the predaceous mites Phytoseiulus persimilis, Typhlodromus recki and Amblyseius californicus, especially the first two.
