dendrolimus pini - Opis:
- The pine lappet moth (Dendrolimus pini L.) has been present in Poland's forests since many years. In 1999−2002, a violent increase in population number of this pest was noted in many regions of the country. In that period the monitoring of pine lappet moth population was carried out also in the stands of the Tuczno Forest District. The presence and density of larvae in tree crowns was established on the basis of the counts of fallen excrements. Obtained results clearly point to a dynamic increase in number of larvae in tree crowns until 2002. The excrement fall control accounted for an increase in percentage of colonised stands on the one hand and a gradual increase in density of larvae in tree crowns on the other one.
