density of population - Opis:
- The knowledge on the spatial distribution of pine foliophagous insect populations can be very useful in forecasting and prevention of their mass outbreaks. Checks of the quantities of fallen excrements were considered one of the reliable methods to detect the distribution of larvae in stands. Such checks oriented, in the first place, on the nun moth were performed in the years 1996−2003. The results showed high differences in the density of larvae even over a small forest area. The presence of such stand fragments where the high densities of larvae occurred more frequently than in other stand fragments were confirmed. In the same forest areas, higher densities of larvae of other foliophagous species of pine were also ascertained.
