Abstract

The process of forest death covers the entire boreal zone of the Northern Hemisphere. Due to the deterioration of the sanitary condition of forest areas, harmful organisms are becoming more active, where the most dangerous pest is Ips typographus. The aim of the work was to study the chemical structure of spruce wood in samples of various living conditions in the zones of active reproduction of bark beetles.The research studies the biochemical composition of Píceao bovata wood within the places of Ips typographus development (bythe example of the Udmurt Republic).The research was carried out within the European part of the Russian Federation, the Udmurt Republic region. The republic area is 42 thousand km2. A total of 15 sample plots were laid out and more than 8,000 trees were analyzed. It was revealed that in the subtaiga zone, the processes of death of spruce stands are observed.

Keywords:
Biochemical composition; Ips typographus; subtaiga zone; deterioration of the sanitary condition
