abstract = "“Flavescence dorée” (FD) is a European quarantine disease affecting grapevines,
associated with the “flavescence dorée” phytoplasma and transmitted by
the North American leafhopper, Scaphoideus titanus. This pathogen has a
significant impact on the major viticultural areas across Europe, as well as all
wine-producing regions in Serbia. The occurrence of S. titanus was initially
recorded in Serbian vineyards in 2002 (Magud and Toševski, 2004). However,
the high population density observed at that time suggests that the vector’s
presence likely dates back to the 1990s (Ivo Toševski, unpublished data).
Despite the extensive measures to contain the pathogen, the encompassing
disease and vector surveillance, the mandatory insecticidal treatments against
S. titanus, and the utilization of certified phytoplasma-free planting material,
the disease continues to spread. Presently, FD affects vineyards in all districts of
Serbia (Krstić et al., 2022). A recent two-year survey (2022-2023) on S. titanus
distribution in both wild and cultivated areas within vineyard ecosystems
revealed widespread prevalence of the vector across all grapevine-growing
regions in Serbia. High population densities were observed in districts where
Map-FD3 genotypes are common. These include grape-producing regions all
over Serbia where the autochthonous M51 genotype is dominant, hosted by
grapevine, along with reservoir plants Clematis vitalba and Ailanthus altissima.
Additionally, substantial S. titanus populations were registered in northern
Serbia, where multiple outbreaks of the M12 genotype occurred, and central
Serbia, where five new genotypes (M150-M154) were detected in grapevines,
indicating a high endemic potential for new outbreaks in these regions. Finally,
significant populations of the insect vector were discovered in riparian habitats
near rivers in Podunavlje and Mačva, where two “flavescence dorée” endemic genotypes of the Map-FD2 (M89 and M148) were found in grapevines (Krstić
et al., 2022). The current phytosanitary situation in Serbian vineyards provides
evidence that, despite measures implemented over the past two decades, there
has been no substantial reduction in the population density and spread of S.
titanus. Due to the high complexity of the “flavescence dorée” epidemiological
cycle caused by natural reservoir plants and native or introduced insect vectors,
linking natural habitats with adjacent vineyard ecosystems, managing ongoing
epidemics and preventing new outbreaks in the Balkans remains a challenge.",
