摘要

In field studies conducted in the Ukraine, infestation by Rhyacionia buoliana on Scots pine (Pinus sylvestris) trees produced an immune response (an increase in the concentration of essential oils). However, not all trees in study plots produced high concentrations of essential oils, allowing small populations of R. buoliana to survive and act as reservoirs for future outbreaks.
