Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with the ability to infest and kill vigorous trees through pheromone-mediated mass attacks. During outbreaks, I. typographus has been observed to occasionally attack Scots pine (SP, Pinus sylvestris). We investigated in the laboratory whether I. typographus is attracted to SP bark and logs, which semiochemicals mediate this potential attraction, and how beetle fitness is affected by the host tree species.
resultsIps typographus was attracted to the odors from SP bark plugs in short-range walking bioassays, and did not prefer the bark odors from NS over SP. In two-choice bioassays with logs, the beetles also did not discriminate significantly between the tree species. Analysis of NS and SP bark volatiles revealed quantitative differences in abundant monoterpenes and their enantiomers; however, none of the monoterpenes elicited a behavioral response when tested individually. Furthermore, we showed that I. typographus can reproduce in SP logs but with reduced offspring weight and numbers. Finally, males emitted less of the aggregation pheromone component cis-verbenol when colonizing SP compared with NS.
conclusionOur results suggest that I. typographus is attracted to SP bark odors at short-range and can reproduce in SP logs under laboratory conditions but with a reduced fitness. The reduced release of cis-verbenol may suggest a reduced likelihood of pheromone-induced mass attacks on SP. © 2026 The Author(s).
