Today conifer-chewing insects cause significant damage to Scots pine forest stands, reducing their productivity and protective functions. The aim of this work was to determine the degree of threat from plantations conifer-chewing pests, in particular, from the pine sawflies Diprion pini. The results of observations of the population Diprion pini pine plantations in the definition of distribution, phenological and biological characteristics of the species. In the survey of plantations inhabited conifer-chewing insects, which set the flash phase is pest populations and which categories are pockets of his breeding, biological characteristics Diprion pini in these conditions.
