Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus.

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
backgroundThe use of double-stranded RNA (dsRNA) for pest insect management presents a promising strategy for protecting crop yields, preserving ecosystem integrity and improving food security and safety. However, to address the natural instability of dsRNA, nanocarriers have been developed to enhance both its stability and cellular uptake in vivo. This study evaluates the laboratory efficacy of naked vs complexed dsRNA in the RNAi-mediated control of the pollen beetle Brassicogethes aeneus, a major insect pest of rapeseed crops. After selecting a synthetic cationic polymer that successfully protects dsRNA from degradation by B. aeneus gut nucleases, pollen beetles were orally exposed to either complexed or naked dsRNA targeting essential genes.
resultsOur results demonstrate that the low-molar-mass synthetic polymer nanocarrier PAEMA enhances the stability of dsRNA in the insect gut environment and facilitates its release. However, it does not lead to an increased mortality rate of B. aeneus.
conclusionThese findings suggest that nanocarrier systems achieving successful dsRNA complexation and enhanced stability do not necessarily result in a significant reduction of survival in pollen beetles. They also highlight the need for a deeper understanding of the complexation and release conditions specific to each dsRNA-nanocarrier system within a relevant biological context to develop effective dsRNA delivery strategies for B. aeneus control. © 2026 The Author(s).
