• Composition of Strawberry Floral Volatiles and their Effects on Behavior of Strawberry Blossom Weevil, Anthonomus rubi 

      Mozūraitis, Raimondas; Hall, David; Trandem, Nina; Ralle, Baiba; Tunström, Kalle; Sigsgaard, Lene; Baroffio, Catherine; Fountain, Michelle; Cross, Jerry; Wibe, Atle; Borg-Karlson, Anna-Karin (Peer reviewed; Journal article, 2020-10-08)
      The strawberry blossom weevil (SBW), Anthonomus rubi, is a major pest in strawberry fields throughout Europe. Traps baited with aggregation pheromone are used for pest monitoring. However, a more effective lure is needed. ...
    • Convergent evolution of semiochemicals across Kingdoms: bark beetles and their fungal symbionts 

      Zhao, Tao; Ganji, Suresh; Schiebe, Christian; Bohman, Björn; Weinstein, Philip; Krokene, Paal; Borg-Karlson, Anna-Karin; Unelius, C. Rikard (Journal article; Peer reviewed, 2019-02-15)
      Convergent evolution of semiochemical use in organisms from different Kingdoms is a rarely described phenomenon. Tree-killing bark beetles vector numerous symbiotic blue-stain fungi that help the beetles colonize healthy ...
    • Fungal symbionts of the spruce bark beetle synthesize the beetle aggregation pheromone 2-methyl-3-buten-2-ol 

      Zhao, Tao; Axelsson, Karolin; Krokene, Paal; Borg-Karlson, Anna-Karin (Journal article; Peer reviewed, 2015-08-25)
      Tree-killing bark beetles depend on aggregation pheromones to mass-attack their host trees and overwhelm their resistance. The beetles are always associated with phytopathogenic ophiostomatoid fungi that probably assist ...
    • Priming of inducible defenses protects Norway spruce against tree-killing bark beetles 

      Mageroy, Melissa; Christiansen, Erik; Långström, Bo; Borg-Karlson, Anna-Karin; Solheim, Halvor; Björklund, Niklas; Zhao, Tao; Schmidt, Axel; Fossdal, Carl Gunnar; Krokene, Paal (Peer reviewed; Journal article, 2019-11-01)
      Plants can form an immunological memory known as defense priming, whereby exposure to a priming stimulus enables quicker or stronger response to subsequent attack by pests and pathogens. Such priming of inducible defenses ...
