No evidence for male attraction to cephalic labial gland pheromones in Bombus terrestris (Hymenoptera: Apidae).
Article in Journal of insect science (Online), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The ecological impact of Bombus terrestris (Linnaeus, 1758) (Hymenoptera: Apidae) following its introduction to regions outside its native range has raised significant concerns, particularly regarding the decline of native pollinators. Male B. terrestris secrete pheromones that are used in reproductive communication, and which have the potential to be used as trap attractants to control invasive populations. However, while gynes (virgin reproductive females) are known to be attracted to these pheromones, nothing is known about behavioral responses of male B. terrestris to them. Here, we investigated whether male B. terrestris exhibit attraction to pheromone extracts from conspecific males under controlled laboratory conditions. A Y-tube olfactometer was used to present B. terrestris males with a choice between a pheromone extract and a control treatment. Males were shown to respond to a positive control of lavender oil; however, they exhibited no attraction to the pheromone extracts. Several factors, such as pheromone concentration, age of individuals, or apparatus design, may have influenced these results. These findings contribute to our knowledge of bumblebee chemical communication and may inform future experimental design to assess pheromone attraction in bumblebees.
