Polygraphus proximus found in Udmurtia, Russia
The native range of Polygraphus proximus (Coleoptera: Scolytinae – EPPO A2 List) includes the Russian Far East, but this species has been introduced in Central European Russia and Siberia where it has become a serious pest of Abies sibirica in taiga forests. In 2019, P. proximus was found for the first time in Udmurtia (Central European Russia). The pest was discovered simultaneously in 4 districts (Zavyalovsky, Malopurginsky, Kiyasovsky and Sarapulsky) in the central and southern parts of Udmurtia. Infested Abies sibirica trees were located near railway tracks and highways, as well as in the depths of natural forests suggesting that the introduction is not recent. It is noted that surveys should be implemented to delimit the extent of the outbreak of P. proximus in Udmurtia and adjacent regions and that management measures should be applied.
The situation of Polygraphus proximus in Russia can be described as follows: Present, only in some areas (native to the Far East, introduced into Central European Russia, Western and Eastern Siberia).
