Scolytus jacobsoni

Description

Scolytus jacobsoni is an elm bark beetle occurring in forests of mixed broad-leaves with elm trees in Asia. In southeastern Russia, during years of outbreaks S. jacobsoni often attacks healthy trees along forest edges or standing alone along roads and in fields and gardens, making it an important pest for elm trees there. Reported hosts include Ulmus davidiana, Ulmus japonica, Ulmus laciniata, Ulmus propinqua, Carpinus betulus, and Pyrus ussuriensis.
