The estimation of the frequency of occurrence of diseased specimens in insect populations in different phases of outbreaks showed that the number of insects infected with NPV (nucleopolyhedroviruses) increased with outbreak escalation and the peak of infected insects was observed during the outbreak decline phase. Rapid decline of outbreak of N. sertifer and L. dispar populations due to NPV infections was observed. Deterioration of population health was observed for P. flammea and D. pini, which resulted in a reduction of population numbers of these pests during the decline phase of outbreak. NPV isolated from larvae of N. sertifer, D. pini and caterpillars of L. monacha, L. dispar and P. flammea showed insecticidal activity under laboratory conditions, and the mortality of infected larvae and caterpillars was higher in comparison with not infected specimens
