Аннотация: The aim of the study was to identify factors with a potential to cause major population change and factors that may explain the differences in population dynamics between outbreak and non-outbreak areas. In particular, outbreak patterns, life history variation, and mortality factors were investigated. Based on results, hypotheses on the population processes were developed as a basis for further stidies and for evaluating population management options.

Аннотация: The results of observations on virus infections of forest foliophagous insects showed prevalence of nucleopolyhedroviruses (NPV) in larvae of the European pine sawfly and caterpillars of the nun moth, the gypsy moth and pine beauty moth. The estimation of the frequency of occurrence of diseasesed spacimens in insect populations in different phases of outbreaks showed that the number of insects infected with NPV increased with outbreak escalation and the peak of infected insects was observed during the outbreak decline phase.
