Conteúdo: | Citrus leprosis was detected in sweet oranges in Chiapas, Mexico, in 2005 based on symptoms. The disease was soon after observed in sweet orange orchards at Huimanguillo and Cunduacan, state of Tabasco. Leaf samples of leprosis-affected Valencia or Hamlin sweet oranges were collected and subjected to ultrastructural examination and molecular detection of CiLV-C by RT-PCR. Cytopathic effects typical of CiLV-C infection as presence of short, baciliform particles in the endoplasmic reticulum cisternae and electron dense, vacuolated viroplasma in the cytoplasm, as well as hypertrophy of some spongy parenchyma cells were observed in the tissues of the leaf lesions. RT- PCR using specific primers for CiLV-C produced DNA fragments of the expected size. Brevipalpus mites were present in these orchards and identified as B. phoenicis, the known vector for CiLV-C. Transmission tests with these mites confirmed their role as leprosis vectors to sweet orange but not to lemon, Volkamerian lemon, C35 citrange and Carrizo citrange. These data confirm the presence of CiLV-C in Tabasco, Mexico and that the citrus leprosis found in Chiapas was caused by CiLV-C. Key words: Brevipalpus phoenicis, Chiapas, citrus leprosis, electron microscopy, molecular detection, Tabasco.
