Czy żerowanie larw foliofagów sosny może mieć pozytywny wpływ na funkcjonowanie drzewostanów?

Different foliophagous species are an inseparable element of forest biocoenoses. Besides damage to asimlatory apparatus of trees which has negative impact on stands the feeding of larvae also cause considerable fall of valuable organic matter onto the forest floor where it undergoes fast decomposition process thus having a positive effect on matter cycling in an ecosystem. Depending on larvae density in three crowns the mass of organic matter falling onto the forest floor can oscillate within wide limits. The decomposition of litterfall supplies the soil with valuable biogenes and microelements. In this situation there appears a "fertiliser effect" advantageous for stands at a simulataneous insignificant loss in assimilatory apparatus.
