- Abstract
The Auchenorrhyncha is one of the most abundant and species-rich insect groups present on grapevine. In our study there are presented the results on abundance, dominance, constancy and ecological significance as well as species diversity of Auchenorrhyncha group monitored in 2016-2018 and 2020-2021 in a network of ninety-five vine plots distributed in vineyards from Banat, Crişana and Maramureş Hills (Western Romania) and Moldova Hills (Eastern Romania). The collecting of insects was on yellow double sticky traps from May/June to October every year. Scaphoideus titanus, the vector for quarantine disease Flavescence dorée, was the most abundant species in vineyards from both zones, followed by Erasmoneura vulnerata, Empoasca spp., Neoaliturus fenestratus, Anoplotettix fuscovenosus and Fieberiella florii. Number of species varied between 31 and 49 species. Shannon-Wiener diversity indexes was 1.61 bits for insects in vineyards of Moldova Hills and 2.09 bits for insects in vineyards of Banat, Crişana and Maramureş Hills. Simson's diversity index was 0.68 for insects in vineyards of Moldova Hills and 0.83 for insects in vineyards of Banat, Crişana and Maramureş Hills. Sorensen′ similarity coefficient was between 0.79 and 0.94 suggesting that the communities of Auchenorrhyncha in vineyards had a similar species composition.
