The authors have studied the peculiarities of seasonal development of horse chestnut leaf miners in green plantations of the Kharkiv region and obtained data were compared with data on the terms of development and temperature conditions in other regions. The sum of effective temperatures required to develop one generation of horse chestnut leaf miner moth was established. Studies of the seasonal development of horse chestnut leaf miners show the overlap of individual generations, which is confirmed by the analysis of the population by stages and ages. It is established that in all years of research, the first maximum density of mines of horse chestnut leaf miner occurred in the period from the third decade of May to the second decade of June, the second – in the I – III decade of July, and the third – in the II – III decade of August. Over the years of research, the density of mines of horse chestnut leaf miners has tended to increase. The highest density of mines of horse chestnut leaf miners was determined in Gorky Park and the Botanical Garden of V. N. Karazin KhNU. The density of butterflies of horse chestnut leaf miner is the highest in the lower part of the trunks.
