Phytophages of linden under the conditions of Grodno Ponemany (Belarus) and Krasnodar (Russia)

Abstract

Comparative studies of linden phytophages in the urban landscapes of Grodno Ponemany (Belarus) and Krasnodar (Russia) have been carried out. 22 arthropod species were revealed, including 6 species of herbivorous ticks and 16 species of insects. Among these organisms, 18 species are representatives of the native fauna, 4 are invasive, while the invaders in the Grodno Ponemany and in Krasnodar are different (two species each). In Grodno Ponemany, oligophages prevail, in Krasnodar, the proportion of polyphages is high. The invasive species Phyllonorycter issikii (Kumata) and native species of gall mites are the most harmful in Belarus. The significance of the invaders in Krasnodar is much lower, and Metcalfa pruinosa Say, and Hyphantria cunea Drury cause significant damage to linden only in the years of sharp increase in number. In Krasnodar, linden spider mite – Schizotetranychus tiliarium (Hermann) is the most harmful, populating 100 % of linden trees older than 10 years. Almost all polyphages, with the exception of the invaders identified for Krasnodar, exhibit moderate or low harmfulness.
