Zika virus does not alter locomotor activity of Aedes albopictus (Diptera: Culicidae).
Article in Revista de saude publica, 2025. 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
objectiveTo investigate the effect of Zika virus on the locomotor activity of a Brazilian population of Aedes albopictus under laboratory conditions.
methodsFemales of Aedes albopictus were infected with Zika virus orally or by intrathoracic injection. The locomotor activity was monitored using a Drosophila activity monitor under controlled conditions of 25°C and a 12h light/dark cycle. The infection status was determined using reverse transcription followed by real-time polymerase chain reaction (RT-qPCR). Statistical analyses were conducted using generalized linear mixed models (GLMMs).
resultsThe locomotor activities of Zika virus-infected and uninfected Aedes albopictus females were diurnal and bimodal, with peaks at lights on and off. The infection did not significantly alter the total activity, diurnal and nocturnal, or the light-on and light-off peaks of infected females compared with uninfected females, regardless of the method of infection (intrathoracic injection or orally).
conclusionThis finding indicates that Zika virus infection does not affect the daily activity pattern of this species under laboratory conditions, which reinforces the importance of this species as a competent and adaptable vector in urban and rural areas, confirming the importance of ongoing surveillance and control strategies.
