The analysis of the modern process of phytophagous insect invasion on the South Coast of the Crimea showed that since the beginning of the active introduction of woody and shrubby plants of foreign breeding for the 18-year period from 2002 to 2020. Fifteen harmful species previously unregistered in the region have been identified. Since 2008, one or two new species have been identified annually, which has led to significant changes in the taxonomic structure of the phytophagous complex in the parks of the South Coast of the Crimea. Invasive phytophages are represented by five orders, of which 26.4% are species of the order Homoptera, 19.8% are species of the orders Lepidoptera, Coleoptera and Hymenoptera, 14.2% are phytophages of the order Diptera. It is established that nine species are monophages, three species are oligophages, and three species are polyphages. Icerya purchasi Mask., Cydalima perspectalis Walker, Ceroplastes japonicus Green, Chrysolina аmericana L., Cameraria ohridella Deschka&Dimic, Bactrocera oleae Rossi and Paysandisia archon Burmeister are the greatest threat to plantings. The terms of detection and the area on the territory of the Crimea, the range of forage plants, the degree of harmfulness, the frequency of occurrence is established, and data on the phenology of the most important species are presented.
