title: Physiological harmfulness of xylophagous insects in poplar and aspen stands in the Left-Bank Forest-Steppe
abstract: Introduction&#x0D; Poplars and aspens (Populus sp.) are common in forest stands, shelterbelts, rural landscaping, and in special plantations as short-rotation woody crops; they are promising tree species for biofuel and bioenergy production.
