Context-dependent effects of carbon dioxide on cross-modal integration during mosquito flight.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
To navigate the environment and search for hosts, mosquitoes utilize multiple sensory cues including carbon dioxide (CO₂), visual, olfactory, and humidity cues. However, how mosquitoes shape their behavior by integrating these cues is poorly understood. Here we monitored the flight maneuvers of Aedes albopictus in a virtual reality environment where sensory cues were presented in open- or closed-loop. We found that CO₂ enhances optomotor responses to wide-field motion stimuli provided with various angular speeds and contrasts. Furthermore, CO₂ allowed more accurate tracking of a low contrast, visual object whose position was updated in closed-loop. We also found that olfactory preference is bidirectionally modulated by CO₂ depending on the value of odors: CO₂ enhances attraction to host odors whereas it enhances aversion to a repellent. This olfactory enhancement was further contingent on the humidity level. Together, our results highlight the context-dependent impact of CO₂ on cross-modal integration in mosquitoes.
