    ABSTRACT

    The Tetranychidae family comprises mite species that are strictly phytophagous and typically associated with medicinal, ornamental, fruit and forest plants. Between August and October 2023, webs and mites were observed on the leaflets of solitary açaí palms [Euterpe precatoria Mart. (Arecaceae)] seedlings, in nurseries in Rio Branco, Acre state, Brazil. The mites were collected, mounted, identified and quantified. The subsequent identification confirmed the presence of three tetranychid species: Tetranychus palmarum Flechtmann & Noronha, 2011, Tetranychus ludeni Zacher and Oligonychus gossypii (Zacher). These species had not been previously recorded on E. precatoria, with only O. gossypii being already reported in the state. Thus, this is the first record of tetranychids infesting solitary açaí palm, and the first report of T. palmarum and T. ludeni in Acre.
