Study of quarantine species of animals in the territory of the PetrSU Botanical Garden

The article shows the study of some quarantine insects and nematodes at the Botanical Garden of PetrSU. They were caught with pheromone traps. Quarantine species of sawyers of Monochamus genus were caught in the territory. They both destruct wood, causing its quality decrease, and transmiss nematodes of Bursaphelenhus genus. The article includes a quantity analysis of the nematodes' appearances and their dependence on the distance of roads. Lepidopterans that pose a threat to the forest sector, such as the Asian type of a Gypsy and Siberian silkworms were not discovered.
