The most significant changes were noted in invasive species of leafhoppers. The reasons are the process of adaptation of the development of leafhoppers to the conditions of the grape ecosystems of the region. According to the results of the research, 12 species of leafhoppers from different ecological-trophic groups, belonging to 5 families, were identified. It was noted that among the studied leafhoppers, the most common invasive species is the Japanese vine leafhopper, which makes up from 8.6 to 25.4% of the total number of inhabited bushes with the number of adults per trap ranging from 4.4 to 9.5 individuals per day. It was established that all examined grape varieties were colonized by the Japanese grape leafhopper, but it was analyzed that the number of colonization in the varieties was different. Varieties with medium or more intensive leaf pubescence were more intensively settled, for example, such varieties as Cabernet Sauvignon, Sukholimansky white, Odesa souvenir, Chardonnay, Odesa black, Rkatsiteli and Tairov Muscat. The smallest number of cycads was detected on varieties without pubescence or with weak pubescence on the lower side of the leaves, such as Arcadia, Flora, Zagadka, Kishmish Tairovskyi, Kardishakh, etc. It has been reliably shown that improving the conditions for the development of grapes while reducing the development and number of the Japanese grape leafhopper has a positive effect on the productivity of the grape plant. KEY WORDS: vineyards, different varieties of grapes, cycads (Cicadinea), Japanese vine cycad (Arboridia kakogawana Mats), distribution of cycads, number of cycads, susceptibility of varieties.
