Abstract
Grapevine flavescence dorée (FD) was detected first in Hungary in 2013 in Zala County (South-West-Hungary). The disease is a serious danger for grapevine growing and grapevine propagating production. In 2014, the pathogen has been found in several new places in Hungary, viz. in Vas and Fejér Counties, and it was also detected in the former location in Zala County. The american grapevine leafhopper (Scaphoideus titanus) is the main vector of the disease. This pest was detected first in Hungary in 2006 and then it has spread all over the country. Since we have not detailed distribution data of this pest in surroundings of Debrecen, therefore we made observations in this region in 2014. The presence of the pest was confirmed by yellow sticky cards in two locations in Debrecen and another site in West Romania near to Hungarian border. We found that S. titanus is present in each sampled sites that cause serious potential danger for the appearance and spread of Grapevine flavescence dorée (FD) in this region.

Phytoplasma vitis’, american grapevine leafhopper, Scaphoideus titanus, vector, invasive pest. Jelenleg megelőző védekezésre a kórokozó mentes szaporítóanyag telepítésével van lehetőség, illetve később a betegség vektora, az amerikai szőlőkabóca (Scaphoideus titanus Ball, 1932) elleni védekezéssel. A kórokozót 2014-ben már több helyen megtalálták a Dunántúlon, Vas megyében Csipkereken, majd Fejér megyében Mór és Vereb közelében, valamint a korábbi Zala megyei előfordulás helyén is. A veszélyes kórokozó terjesztéséért felelősnek tartott kabócafaj, a Scaphoideus titanus jelenlétét Európában először 1924-ben mutatták ki Franciaországban. 1. ábra: Amerikai szőlőkabóca 2014-ben Debrecen Bayk András kertben gyűjtött példánya
