Bacterial Communities in Aphid Honeydew Provide Species-Specific Functional Chemical Cues in Aphid-Predator Interactions.
Article in Journal of chemical ecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 role of microbial communities in aphid honeydew in shaping multitrophic interactions remains uncertain, while bacterial diversity and its variation among aphid species and ageing are still underexplored. This study investigated variations in bacterial community structure and VOC profiles of honeydew between two aphid species (Aphis fabae, Acyrthosiphon pisum), across time from fresh to 72-hour aged. We also assessed the behavioral responses of a natural enemy of aphids, the hoverfly Episyrphus balteatus, to different honeydew combinations. Aphis fabae honeydew harbored a more diverse bacterial taxonomic richness than A. pisum, including a significant shift in bacterial community composition over time that also extended to the semiochemical profiles. Further, 24-hour-aged honeydew from A. fabae emitted a higher concentration of volatile compounds than A. pisum. We assessed E. balteatus preferences for aged honeydew from both aphid species using wind tunnel assays, revealing a strong attraction to 48-hour-old A. pisum honeydew resulting in higher egg-laying activity. These findings underscore the role of microbial succession in aphid honeydew in shaping multitrophic interactions, suggesting potential biocontrol strategies by modulating microbial influences on aphidophagous beneficial behavior.
