Abstract <p>Phyllophagous insects are an integral component of forest biogeocenoses and play an important role in their functioning. Some phyllophagous species have periodical mass propagation outbreaks, exerting a great direct and indirect influence on forest stands. When severe damage to foliage is caused repeatedly, they sometimes lead to the death of trees and whole stands. A review has been carried out, encompassing the studies of phyllophagous insects in oak stands of the Tellerman forest massif over several decades (mainly in the Tellerman experimental forestry unit of the Institute of Forest Science of the Russian Academy of Sciences (IFS RAS)), regarding the confinement of the aforementioned insects to forest types and phenological forms of common oak. This study presents the features of several propagation outbreaks of three species of phyllophagous insects: winter moth, gypsy moth, and green oak leafroller, recorded on the territory of the forestry during its existence.</p>
