Abstract

Citrus leprosis, commonly caused by Citrus leprosis virus C (Cilevirus), is currently the viral disease most impact on citrus production due to the high cost with the use of acaricide for the management and vector control. The disease is associated with mites of the genus Brevipalpus (Acari: Tenuipalpidae), which are polyphagous, cosmopolitan, and have been the focus of increased attention by other viruses transmission in different plant species. It is necessary to understand increasingly this mite within the leprosis pathosystem to reducing their occurrence and dispersion of CiLV-C inoculum in the field, resulting in a lower environmental and financial impact to producers. In recent years, several studies have enlarged the knowledge of leprosis and its vector, highlighting the recent taxonomic revision of the species B. phoenicis, which had recovered some synonyms and new species described for the group. This repositioning has direct implication in this virus-vector interaction, turning the investigation into the diversity of studies and a possible specificity in the acquisition and inoculation of virus leprosis for these species revised and newly described. Preliminary results of research in Centro de Citricultura Sylvio Moreira-IAC (CCSM-IAC), in partnership with other institutions, indicated the possible use of molecular markers in taxonomic context integrative, and using genomics and transcriptomics as strategies to advance knowledge and vector control. It is hoped that the continuation of this work, focusing on virus-vector interaction, with functional genomics and gene expression data, add more information about the pathosystem leprosis and provide data for the development of innovative tools for sustainable management of the disease in orchards.
