Abstrakt

The paper presents results of 3-years observations on pine bark bug (Aradus cinnamomeus Panz.) populations dynamics in young Scots pine stands in two Forest Districts in Central Poland. Estimation of pine bark bug threat in pine stands depends on great differences of this pest density recorded between early and late stages of generation. This should be taken into consideration when the decision on chemical control is decided.
