Abstract
Key messageThe dog detection allows timely removal by sanitation logging of first beetle-attacked trees before offspring emergence, preventing local beetle increases. Detection dogs rapidly learned responding to synthetic bark beetle pheromone components, with known chemical titres, allowing search training during winter in laboratory and field. Dogs trained on synthetics detected naturally attacked trees in summer at a distance of >100m.ContextAn early detection of first beetle-attacked trees would allow timely sanitation felling before offspring emergence, curbing local beetle increase.AimsWe tested if detection dogs, trained off-season on synthetic pheromone components from Ips typographus, could locate naturally bark beetle-infested spruce trees.MethodsIndoor training allowed dogs to discriminate between the infestation odours (target) and natural odours (non-target) from the forest. Odour stimuli were shown by chemical analysis to be bioactive at extremely low-levels released (
