Abstract: | A survey of Brevipalpus-transmitted plant viruses (BTrV) was carried out in the cities of Manaus and Presidente Figueiredo, and in the oil exploratory base of Urucu, Amazonas State, Central Amazon Basin, Brazil. The main characteristics considered during the survey were the occurrence of localized symptoms (chlorotic or brown spots, ringspots, green spots in senescent leaves) similar to those previously described for BTrV and infestation by Brevipalpus mites. For the evaluation of the infection by putative BTrV, small fragments of the leaf lesions were fixed in loco and later processed for ultrastructural electron microscopy at Piracicaba, SP. Thirteen plant hosts of presumed BTrV were found. Three of them probably represent previously described BTrV infecting Hibiscus rosa sinensis, H. syriacus and Clerodendrum x speciosum. For the first time we report cases of infection by putative BTrV of nuclear type in chlorotic spot in Piper callosum (Piperaceae), chlorotic ringspot in Monstera deliciosa (Araceae), chlorotic spot in Ruellia chartacea (Acanthaceae), chlorotic spot in Bidens sp. (Asteraceae), green spot in Allamanda chatartica (Apocynaceae), chlorotic spot in Gardenia sp. (Rubiaceae), chlorotic ringspot and green spot in Mussaenda erythrophylla. (Rubiaceae) and of cytoplasmic type in Clerodendrum speciosissimum (Lamiaceaae) and ringspots in Arundina graminifolia (Orchidaceae). All these plants were infested by Brevipalpu. phoenicis.
