Opis:: Effect of a weak defoliation by the larvae of the lappet moth and nun moth on chemical composition of needles, litter and soil in the 33−years old Scots pine stands was studied. The four variants were tested: I – larvae feeding, litterfall with frass and damaged needles, II – larvae feeding, but litterfall excluded (collected), III – no larvae, litterfall from the variant II spilled around trees, IV (untreated) – no larvae, litterfall without frass and damaged needles. No changes in chemical composition of litter and soil after two years of weak spring defoliation were found. However, there was a significant decrease of soluble carbohydrates and 5 sesquiterpenes as well as an increase of total monoterpenes in needles of trees in the variant II in comparison to other variants. All of those compounds are carbon−based, thus trees probably only relocated this element to a higher production of monoterpenes to make needles less attractive as a food source.
