Preliminary studies on arctic bark beetles (Coleoptera: Scolytidae) of the Noatak River drainage 1
Abstract Preliminary biological studies of arctic Scolytidae were carried out during a scientific expedition of northwestern Alaska. Eight scolytid species were found associated with Picea glauca and a significant range extension for Dendroctonus punctatus was noted. Ips borealis host selection beha...
