<p><strong>An overview of </strong><strong><em>Brevipalpus </em></strong><strong>mites (Acari: Tenuipalpidae) and the plant viruses they transmit*</strong></p>

Abstract

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 need for more intensive research to identify the extent of this species complex throughout the western hemisphere. More stringent guidelines are needed for the inspection and movement of live plant materials that are host plants for Brevipalpus mites from one country to another.

New Report ofBrevipalpus yothersi(Prostigmata: Tenuipalpidae) on Blueberry in Florida

“…Brevipalpus spp. usually feed on twigs, leaves, and fruit (Childers et al 2011). The symptoms associated with injury caused by these mites vary from necrotic brown spots on leaves, resinous leaf patches with opposing leaf, stem browning, gall formation, brownish patches on the fruit surface, corky ring-like bands around the fruit to defoliation and die back depending on the host plant species (Childers et al 2003).…”

“…These mites cause direct damage by inserting their mouthparts into plant tissues and sucking sap. They also inject their toxic saliva into the plant during feeding (Childers & Rodrigues 2011). Furthermore, several of these mites transmit viruses to host plants (Mesa et al 2009;Salinas-Vargas et al 2016).…”

Dichorhavirus: a proposed new genus for Brevipalpus mite-transmitted, nuclear, bacilliform, bipartite, negative-strand RNA plant viruses

“…Mites belonging to at least three distinct species can persistently transmit bacilliform 'nuclear-type' viruses, including B. californicus Banks, 1904; B. phoenicis Geijskes, 1939; and B. obovatus Donnadieu, 1875 (reviewed in ref. [10]). A minimum inoculation access period of 30 min is required for transmission of OFV by B. californicus mites, and mites are capable of transmitting OFV after a three-week latent period on a virus-resistant host [28].…”

Revisão taxonômica do ácaro da leprose dos citros e sua distribuição no Brasil

“…A maioria das espécies que causam danos econômicos a plantas cultivadas, incluindo ornamentais, pertence ao gênero Brevipalpus (Jeppson et al, 1975;Childers & Rodrigues, 2011 (Chagas, 1973;Ochoa et al, 1994;Chagas et al, 2001Chagas et al, , 2003Childers et al, 2001;Rodrigues et al, 2008;Kitajima et al, 2010;Rodrigues & Childers, 2013;Alberti & Kitajima, 2014;Ramos-González et al, 2017;Nunes et al, 2017).…”
