   Abstract : Ips typographus (Coleoptera: Curculionidae, Scolytinae) is a pest species that mainly attacks Norway spruce (Picea abies L. Karst.) and can kill large volumes of spruce trees during outbreaks, leading to economic losses of great magnitude. A common practice to manage attacks is to remove recently killed trees and thereby remove the beetles. READ MORE

   Abstract : Granbarkborren, Ips typographus, är en av få arter som kan öka drastiskt i populationsdensitet och leda till en omfattande dödlighet av träd i skogen. Skadorna år 2020 uppgick till ett värde på 3,5 miljarder kronor, vilket gör det värdefullt att försöka förstå varför dessa utbrott sker och vad för åtgärder som kan vidtas för att undvika dem.
