An overview of Brevipalpus mites (Acari: Tenuipalpidae) and the plant viruses they transmit*
Zoosymposia, 2011
The significance of the family Tenuipalpidae has risen from near obscurity to that of considerable economic importance over the last five decades. One or more species within the genera Brevipalpus, Cenopalpus, Dolichotetranychus, Raoiella, and Tenuipalpus are recognized as serious economic plant pests. However, only three species within the genus Brevipalpus are known to vector one or more cytoplasmic or nuclear type plant viruses, including citrus leprosis, coffee ringspot, green spot on passion fruit, and orchid fleck viruses. Related viruses have been identified in numerous ornamental plants that are vectored by B. phoenicis and B. obovatus. Affected plant species, their current distributions and known mite vectors are summarized in this paper. The life cycle and developmental times for the three Brevipalpus species are reviewed. Cryptic species within B. phoenicis have been identified on Hibiscus in Florida and Citrus sinensis in Honduras within recent years. This dictates the n...

The family Tenuipalpidae has over 622 species in 30 genera described worldwide. A total of 928 plant species in 513 genera within 139 families are recorded hosts of one or more of the following species: Brevipalpus californicus (Banks), B. obovatus Donnadieu, and B. phoenicis (Geijskes). B. californicus has 316 plant species reported as hosts compared with 451 and 486 host plants for B. obovatus and B. phoenicis, respectively. There are 67 genera of plants within 33 families that are reported hosts of only B. californicus, 119 genera within 55 plant families that are hosts of only B. obovatus, and 118 genera of plants within 64 families that are hosts of only B. phoenicis. There are 14 genera of plants within 12 families that are hosts to both B. californicus and B. obovatus, while there are 40 genera of host plants within 26 families that are hosts for both B. californicus and B. phoenicis. A total of 70 genera of host plants within 39 families have been reported as hosts of both B. obovatus and B. phoenicis, while 77 genera of plants within 44 families have been reported as hosts of all three Brevipalpus species. Geographical differences in the three species of Brevipalpus identified on different plant species within the same genus are common.

The Recôncavo is responsible for almost 20% of citrus production in the state of Bahia, Brazil, where the occurrence of the Citrus leprosis virus (CiLV) has been recorded, one of the most important viruses in citrus cultivation, and whose vector is the Tenuipalpidae mite (Brevipalpus phoenicis). This study is to define the minimum sample size to quantify the prevalence, incidence and spatial distribution of the mite vector in the Recôncavo Baiano (RB). Two pilot samplings were made in 145 orchards located in 13 municipalities, in April and September 2008, at the end of the drought and rainy period, respectively. In each orchard, three fruits per plant were inspected using a pocket magnifying glass (magnification10x), with a total of 21 plants/orchard, recording the presence or absence of the mite vector. Maximum prevalence (100%) of the mite was found in RB in both samplings. To estimate the incidence of infestation in plants, a minimum of 18 orchards should be sampled, and the minimum sample size was 89 orchards to estimate the infestation in fruits. Infestation of Brevipalpus was verified in 74% and 63% of the plants and in 41% and 34% of the fruits in April and September, respectively. The dispersion index (DI) was about 2.59 and 4.72, classifying the spatial distribution of orchards infested by B. phoenicis in the agro-ecological conditions of the RB as aggregated. No symptom of CiLV was detected, characterizing the RB as an area free of this virus.
Brevipalpus-associated viruses in the central Amazon Basin
Tropical Plant Pathology, 2008
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.
