Screening for phytoplasma presence in leafhoppers and planthoppers collected in Bulgarian vineyards

摘要

In the beginning of 2003, the Bulgarian Food Safety Agency started the monitoring program for quarantine pests on grapevine. The object of surveys was to verify the possible presence of 'flavescence dorée' phytoplasmas. At the same period entomological surveys were carried out with yellow sticky traps in the vineyards surveyed. Identification of Scaphoideus titanus Ball. was done in the summer of 2006 in Varna and Veliko Turnovo regions. For the control of natural spreading of phytoplasmas in Bulgarian vineyards individual testing by PCR of the collected planthoppers and leafhoppers in order to define phytoplasma presence and increase knowledge on the grapevine phytoplasma vectors in Bulgaria was carried out.
