INVASION SPECIES OF HERMES <i>PINEUS STROBI </i>(HARTIG 1839) (HEMIPTERA: ADELGIDAE)<i />ON<i> PINUS STROBUS </i>L. IN CENTRAL REGIONS OF EUROPEAN RUSSIA
During forest-pathological monitoring in the plantings of Weymouth pine Pinus strobus L. in three regions of the central part of European Russia - Voronezh, Kursk and Oryol - an invasive species of Weymouth pine pest, Hermes Pineus strobi (Hartig 1839), was identified. The vector of hermes invasion in a given territory, degree and rate of spread, localization of colonies on trees, dynamics of development in industrial, experimental forest cultures and clone archives were established. Sources of distribution of the pest in the Voronezh Region are Weymouth pine cuttings from the Oryol and Kaliningrad regions.
