Non-target Bark Beetles in Ips duplicatus (Sahlberg) Pheromone Traps Baited with Host Volatiles
Response of several non-target bark beetles (Coleoptera: Curculionidae, Scolytinae) to different combinations of the northern spruce bark beetle’s synthetic pheromone with the monoterpenes (-)-alpha-pinene and (+)-limonene has been studied in choice ...
