Ocorrência do vírus da pinta verde em maracujá no Estado do Maranhão, Brasil

Abstract

Occurrence of Passion fruit green spot virus in the passion fruit crop in the State of Maranhão, BrazilYellow passion fruit (Passiflora edulis f. flavicarpa) plants with characteristic symptoms of the green spot disease (yellow fruits with green spots, necrotic lesions in the stems, green patches in senescent leaves) were observed in commercial fields in the State of Maranhão, associated with infestation by the tenuipalpid mite Brevipalpus phoenicis. Transmission electron microscopy was performed on tissue from the green spots of the fruits, revealing the presence of short bacilliform particles within endoplasmic reticulum cisternae and dense viroplasm in the cytoplasm, typical of the cytoplasmic type of Brevipalpus-borne viruses. This confirms that the causal agent of the disease was the Passion fruit green spot virus. This is the first report of this virus in the State of Maranhão.

“…The Brevipalpus phoenicis mite (Geijskes) (Acari: Tenuipalpidae) until 2015 was considered as the only vector of CoRSV, being also pointed as transmitting numerous viruses to other plants, including the main viral disease of the Brazilian citrus, the citrus leprosis (Citrus leprosis virus -CiLV) (Bastianel et al, 2010;Rodrigues;Freitas-Astúa, 2010) and the passion fruit green spot disease (Moraes et al, 2006). However, Beard et al (2015) found that this species is a morphospecies complex.…”

“…A doença, causada por vírus, vem reduzindo a vida útil dos pomares de dois para um ano ou mesmo inviabilizando a produção em muitas áreas. Além da Bahia, essa virose já foi constatada no Distrito Federal e em outros estados brasileiros como Maranhão, Minas Gerais, Pará, Paraíba, Rio de Janeiro, Rio Grande do Norte, Rondônia e Sergipe (Kitajima et al, 2003;moraes et al, 2006;antonioli-luizon et al, 2009).…”

“…Em 1997, comprovouse que uma doença, designada de pinta verde do maracujazeiro (Passiflora edulis Sims f. flavicarpa Deg) (passionfruit green spot virus -PGSV), que estava dizimando culturas na região de Vera Cruz, SP, era de natureza viral e transmitida pelo B. phoenicis (Kitajima et al, 1997). Hoje já se tem relato desta doença no estado de Minas Gerais, Bahia e Maranhão (Takatsu et al, 2000;Chagas et al, 2000;Morais et al, 2004). Maeda et al (1998) (Bitancourt & Grillo, 1934).…”
