Contribution to the knowledge of Auchenorrhyncha (Hemiptera) fauna in the vineyards of Krasnodar region, Russian Federation

Relevance. The vineyards of the Krasnodar Territory cover over 31,000 hectares, accounting for approximately 60% of all vineyards in Russia. Assessing the phytosanitary status of ampelocenoses and understanding the role of Auchenorrhyncha in transmitting dangerous systemic diseases, such as Pierce’s disease, bois noir phytoplasma, and flavescence dorée, is crucial for maintaining vineyard health.

The  purpose  of  the  research is to identify the current species composition of Auchenorrhyncha suborder in the vineyards of the Krasnodar Territory. Based on literature data and field observations, the study evaluates their actual and potential impact on vineyards.

Methods. Sampling was conducted during the 2023–2024 growing seasons using entomological nets, yellow sticky traps, and a combination of ultraviolet (365 nm) and white light traps.

Results. In total, 51 species from 9 families of the suborder Auchenorrhyncha were identified. Special attention is given to the biology and ecology of these insects, particularly their role as both direct pests and vectors of infectious diseases. Widespread distribution of Scaphoideus titanus and Philaenus spumarius, vectors of dangerous quarantine diseases of golden yellowing and Pierce’s disease, respectively, has been revealed. Additionally, a preliminary list of potential vectors of bois noir phytoplasma was compiled. The occurrence of a second generation of Metcalfa pruinosa, uncommon for this species, was noted, along with a preliminary complex of species associated with grapevine chlorosis. This study represents the first comprehensive investigation of Auchenorrhyncha in the vineyards of the Krasnodar Territory.
