Invasive organisms in the persimmon collection at Nikita Botanical Gardens.
The south coast of the Crimea is quite an isolated territory. On the north it is separated by the Main Ridge of the Crimean Mountains from the rest of the peninsula and on the South it is bordered by the waters of the Black Sea. But because of the active import of plant material from abroad, invasive organisms can come and cause great damage to horticulture of the Crimea. A new pest Ceroplastes japonicus Green. was discovered in the persimmon collection in Nikita Botanical Gardens in spring of 2016. All found pests were located exclusively on trees of three cultivars 'Hyakume', 'Yankin Tsuru' and 'Nikitskaya Bordovaya'. On trees of other cultivars and species (D. virginiana L. and D. lotus L.) the presence of Ceroplastes japonicus has not recorded until now.
