Abstract
The horse chestnut leaf-miner (Cameraria ohridella Deschka & Dimic, 1986) is alien to the fauna of Belarus, an invasive species of mining phytophages, the main pest of horse chestnut Aesculus hippocastanum L. in Belarus. The annually observed C. ohridella mass outbreaks lead to the fact that the crowns lose their natural appearance and defoliate earlier, that affects the decorative and recreational qualities of green areas catastrophically. Based on the data of long-term (2013-2019) studies, a quantitative assessment of the physiological damage ability, ecologically conditioned and the general harmfulness of horse chestnut leaf-miner in all 5 regions of woody plants introduction in Belarus is given. The values of the indicators of physiological damage ability and general harmfulness were statistically different for most regions of woody plants introduction. They were minimal for the North and maximum for the Southern regions of woody plants introduction in Belarus.
