“…Therefore, the identity of this Brevipalpus specimen needs further identification based on morphological keys using scanning electron microscopy ( Beard et al, 2013 ). B. yothersi has been reported as the main vector of CiLV-C and CiLV-C2 ( Roy et al, 2013 ; García-Escamilla et al, 2018 ; Ferreira et al, 2020 ). In this study we demonstrated the ingestion and potential acquisition of HYBV by B. yothersi using dRT-PCR assays targeting both RNA 1 and 2 of the virus.…”

Hibiscus (Hibiscus spp.) are popular ornamental and landscape plants in Hawaii which are susceptible to foliar diseases caused by viruses belonging to the genera Cilevirus and Higrevirus (family Kitaviridae). In this study, a virus infecting H. rosa-sinensis plants displaying foliar symptoms consistent with infection by a kitavirus, including yellow chlorotic blotches with a green perimeter, was characterized. The genome consisted of two RNAs 8.4 and 4.4 kb in length, and was organized most similarly to cileviruses, but with important distinctions. These included the location of the p29 homolog as the 3′-terminal open reading frame (ORF) of RNA2 instead of its typical locus at the 3′-end of RNA1; the absence of a p15 homolog on RNA2 and the adjacent intergenic region which also harbors small putative ORFs of unknown function; and the presence of an ORF encoding a 10 kDa protein at the 3′-terminal end of RNA1 that was also found to be present in the hibiscus green spot virus 2 genome. Spherical particles approximately 55–65 nm in diameter were observed in infected leaf tissue, and viral RNA was detected by reverse-transcription PCR in individual mites collected from symptomatic plants tentatively identified as Brevipalpus yothersi. Although phylogenetic analyses placed this virus between the higrevirus and cilevirus clades, we propose the tentative taxonomic placement of this virus, designated hibiscus yellow blotch virus (HYBV), within the genus Cilevirus.

“…Currently, we are sequencing the RNA 2 region of CiLV-C samples isolated from orange and lime infected trees to assess genetic variation. A previous report suggested that B. californicus might be responsible for transmission of OFV-Cit strains but not CiLV-C (García-Escamilla et al, 2018). These authors By 2016, symptoms associated with citrus leprosis were found in the states of San Luis Potosí, Hidalgo, Jalisco, Oaxaca, Puebla, Quintana Roo and Tamaulipas (SENASICA, 2017a).…”

Citrus leprosis is one of the most important diseases affecting citrus crops in the Americas. Mexico is the sixth largest producer of oranges and the largest producer of limes worldwide. Citrus leprosis was first detected in Mexico as recently as 2005. Since then, this disease has been detected in all Mexican citrus producing areas. Here, we describe the current geographical distribution of the viruses associated with the Citrus leprosis (CiLV-C and OFV-Cit) and its vectors which are mite species in the genus Brevipalpus. We describe the outcomes of transmission experiments undertaken in Mexican populations of B. yothersi and B. californicus on different citrus species. Potential relationships between symptoms and the presence of CiLV-C and/or OFV-Cit are described. Finally, we identify future research needed to increase our knowledge of the epidemiology of citrus leprosis in Mexico.

“…Há de se ressaltar que os ácaros do complexo B. phoenicis são considerados como os principais vetores de vírus, no caso da leprose dos citros (Citrus leprosis virus -CiLV), não só aqui no Brasil, como em diversos outros países. Sabe-se também que B. californicus não esteja associada à leprose no Brasil, está associada à leprose no México (OFV-citros) (Garcia-Escamilla et al, 2018). Porém é uma espécie de ocorrência rara nos pomares citrícola do Brasil e que também está passando por uma extensa revisão, assim como ocorreu com B. phoenicis.…”

RESUMOO gênero Brevipalpus pertence à família Tenuipalpidae (Acari: Trombidiformes), cujos membros geralmente são referidos como ácaro plano. Esses ácaros estão presentes em regiões tropicais e subtropicais. O reconhecimento das espécies de Tenuipalpidae tem sido bastante dificultado pela variação morfológica natural de cada espécie. A proposta deste artigo é apresentar uma revisão taxonômica para os ácaros encontrados em citros no Brasil, para tentar resolver uma série de dificuldades taxonômicas e de nomenclatura. Até o presente momento, foram encontradas as seguintes espécies: Brevipalpus phoenicis (Geijskes), Brevipalpus papayensis Baker e Brevipalpus yothersi Baker, sendo esta última a mais comum nos pomares citrícolas do estado de São Paulo. Termos de indexação: Brevipalpus phoenicis, Brevipalpus yothersi, Brevipalpus papayensis. Taxonomic revision of the citrus leprosis mites and their distribution in Brazil SUMMARYThe Brevipalpus genus belongs to the family Tenuipalpidae (Acari: Trombidiformes), whose members are commonly referred to as flat mite. These mites are present in tropical and subtropical regions. The recognition of Tenuipalpidae species has been greatly hampered by the natural morphological variation of each species. The purpose of this paper is to present a taxonomic revision for the mites found in citrus in Brazil, to try to solve a number of taxonomic and naming difficulties. To date, the following species were found: Brevipalpus phoenicis (Geijskes), Brevipalpus papayensis Baker and Brevipalpus yothersi Baker, the latter being the most common species in citrus orchards in the state São Paulo.
