Abstract
Grape phylloxera was imported into Europe from North America with grapevine roots around 1860. The pest then spread rapidly across Europe and destroyed two-thirds of continental vineyards.
Grapevines grafted onto resistant rootstocks are now widely used in Europe to protect against phylloxera.
Over the last few centuries grape phylloxera has adapted to thrive on rootstock roots and thereby expressed vine damage.
We have little knowledge about the genomic structure of Hungarian phylloxera, therefore a representative experiment was conducted to examine the genetic structure of grape phylloxera in Hungary.
Most of the populations were collected in Southwest Hungarian vineyards, and several from other parts of the country.
Total DNA was extracted from adults, and a PCR (polymerase chain reaction) analysis was performed using a 12-mer primer pair.
Our results indicate that the Hungarian phylloxera populations create three groups according to similarity.
