Population dynamics and stability of forest insects with low density (using the example of populations of the bordered white Bupalus piniarius L.)

The abundance dynamics of different populations with the bordered white Bupalus piniarius L. has been analyzed. It has been demonstrated that the populations of B. piniarius in different habitats at the territory of Europe and the Asian part of Russia have cyclic oscillations in their density when in a stable-sparse state. A mathematical model describing regulatory processes in the population of B. piniarius in a stable-sparse state has been proposed.
