Oriental Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae): New Inhabitants of Primorsky Krai in Russia

Аннотация

Cnestus mutilatus (Blandford, 1894) and Microperus quercicola (Eggers, 1926) are recorded in Russia for the first time. These beetles were collected near the city of Partizansk (Primorsky krai) on native tree species by E.A. Yakushkin in 2017. Along with these ambrosia beetles, we recorded Xylosandrus germanus (Blandford, 1894), which recently emerged in the region, and Cyclorhipidion pelliculosum (Eichhoff, 1878), Xyleborus seriatus Blandford, 1894, and Anisandrus maiche (Kurentsov, 1941), which are known from the Far East of Russia. Since all these Xyleborini beetles are known to be polyphagous, can produce males by parthenogenesis, and are easily transported with wood, their potential for invasion in the European part of Russia is high. Photographs and ink drawing of ambrosia beetles are given.
