Materials for studying alien arthropods of the Karadag mountain range

A total of 35 alien arthropod species from 21 families, 6 orders and 2 classes were identified in the area of the Karadag mountain range. It is found that the main donor regions of invasive species are the non-tropical regions of Asia, North America and the Mediterranean, typical for the Eastern Black Sea region. Corythucha arcuata (Say, 1832) is a threat to the natural ecosystems of the Karadag Nature Reserve. Scaphoideus titanus Ball, 1932, Eriosoma lanigerum (Hausmann, 1802), Halyomorpha halys Stål, 1855, Nezara viridula (Linnaeus, 1758) and Tuta absoluta (Meyrick, 1917) are considered dangerous pests to agriculture while Corythucha ciliata (Say, 1832), Phyllonorycter platani (Staudinger, 1870), Acizzia jamatonica (Kuwayama, 1908), Cacopsylla pulchella (Löw, 1877), Prociphilus fraxinifolii (Riley, 1879), Dasineura gleditchiae Osten Sacken, 1866, Cameraria ohridella Deschka & Dimic, 1986, Cydalima perspectalis (Walker, 1859), Pulvinaria floccifera (Westwood, 1870) and Unaspis euonymi (Comstock, 1881) pose threats to gardens and parklands. Moreover, C. ohridella, C. ciliata, C. perspectalis and Harmonia axyridis Pallas, 1773 are listed among the 100 most dangerous invasive species in Russia. The Unified List of Quarantine Items of the Eurasian Economic Union includes C. ciliata, H. halys, C. arcuata and T. absoluta. Monitoring the alien component of biota and studying the consequences of biological pollution of natural ecosystems should become a new urgent focus of scientific, organizational and educational activities at the Karadag Nature Reserve.
