TWO YEARS OF THE LEAFHOPPER SCAPHOIDEUS TITANUS DYNAMICS ON PERGOLA HYBRID VINE IN A HOME GARDEN

Abstract

The grapevine leafhopper Scaphoideus titanus Ball 1932 is an invasive species of North American origin reported in Europe in the 1950s in France where it was accidentally introduced. Shortly after, the species was identified as a natural vector of the phytoplasma associated with the Flavescence Dorée disease in French vineyards. The species quickly spread to other European countries, including Romania. This paper presents data regarding density and population dynamics of S. titanus recorded during two years of monitoring with yellow sticky traps on a pergola hybrid vine in a home garden in Northern Bucharest area. The nymphs were caught from the end of May (2021) until early August (2020) and mid-July (2021). The adults have appeared from the beginning of July until end of October in 2020 and until the middle of October in 2021, with a peak in September 2021 and August 2020.
