Biocontrol potential of aqueous and methanolic extracts of Russian knapweed, Acroptilon repens, L. (Asteraceae) against Trialeurodes vaporariorum (Hemiptera: Aleyrodidae).
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 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
Plant based natural products could be used as new alternative of chemical insecticides due to their co-friendly, safety to non-target organisms, and low-level resistance properties. In this study, the contact toxicity and sublethal effects of Acroptilon repens L., Russian knap weed, extracts (aqueous and methanolic) were evaluated on the biological, population traits and population projection of greenhouse whitefly, Trialeurodes vaporariorum. The essential oil was extracted from the plant by steam distillation using a Clevenger apparatus and the chemical compounds were identified by gas chromatography-mass spectrometry. Twenty-three chemical components of A. repens were characterized, in which caryophyllene oxide (30.67%) and α-copaene (15.05%), were identified as the predominant compounds of Russian knapweed. Moreover, the results illustrated that some secondary metabolites (e.g. flavonoids, alkaloids and polyphenols) were rich in methanolic extract compared to the control. The leaf dipping method was used for the bioassay tests against whiteflies. According our findings, the aqueous extract (LC
