IMPACT OF CAMERARIA OHRIDELLA INFESTATION ON CHEMICAL COMPOSITION OF AESCULUS GLABRA WILLD LEAVES IN DNIPRO CITY, UKRAINE

Abstract

This study examines how infestation by the horse chestnut leaf miner affects the metabolic profile of Aesculus glabra leaves in urban conditions in Dnipro, Ukraine. Using GC-MS analysis, researchers found a significant reduction in chemical diversity, with identified compounds decreasing from 114 to 62 in infested leaves. The results indicate a major metabolic reorganization under biotic stress, including reduced carbohydrate-related compounds and the emergence of metabolites linked to plant defense. These findings highlight adaptive biochemical responses and offer insights for developing sustainable strategies to manage leaf miner infestations in urban environments.
