چکیده
Plum leaf scald (PLS), caused by the vector-borne bacterium Xylella fastidiosa, is a major obstacle to expansion of plum crops in Brazil. In other affected crops, this pathogen naturally transmitted mainly sharpshooter leafhoppers (Hemiptera: Cicadellidae: Cicadellinae). Despite importance PLS, vector species responsible for bacterial spread plums remain unknown. This study, therefore, aimed determine X. fastidiosa transmission ability three commonly found orchards southern and southeastern Brazil: Macugonalia cavifrons (Stål), leucomelas (Walker), Sibovia sagata (Signoret). After 72-h acquisition access period trees infected with subsp. multiplex (sequence type 67), insects were transferred an inoculation 96 h 10–20 healthy Prunus salicina plants each species, using four per plant. Bacterial infection was verified 7 months after polymerase chain reaction. Results showed that able transmit plums, mean efficiencies single 16%, 14%, 18% M. cavifrons, leucomelas, S. sagata, respectively. To our knowledge, study first identify prove PLS strain sharpshooters

Xylella fastidiosa, a fastidious bacterium causing disease in over 100 plant species, is classified as a single species, although genetic studies support multiple taxons. To determine the taxonomic relatedness among strains of X. fastidiosa, we conducted DNA-DNA relatedness assays and sequenced the 16S–23S intergenic spacer (ITS) region using 26 strains from 10 hosts. Under stringent conditions...

Xylella fastidiosa (Xf) subsp. Pauca causes citrus variegated chlorosis (CVC) disease in Brazil, resulting in significant production losses in the citrus industry. Xf is mainly transmitted by three species of sharpshooters (Hemiptera: Cicadellidae) in Brazil; Dilobopterus costalimai (Young), Acrogonia citrina Marucci & Cavichioli and Oncometopia facialis (Signoret). We identified bacterial comm...

This report presents the progress obtained in the development and application of an RNA interference (RNAi) based system aimed to target genes of the vector of Xylella fastidiosa(Xf), the glassy-winged sharpshooter (GWSS; Homalodisca vitripennis). After demonstrating that RNAi induction in GWSS cells and insects is achievable, in the year 2008-2009 we started screening a large pool of candidate...
