Gum Arabic containing Allium sativum L. essential oil-based nanoparticles as biofumigant grain protectant against Callosobruchus maculatus F.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Gum Arabic nanoparticles (GA NPs) were used to nano-encapsulate Allium sativum or garlic essential oil (GO) using the freeze-drying technique. The fumigant toxicity of GO and GO-GA nanoparticles was evaluated against Callosobruchus maculatus, a major pest of stored products. Adults were exposed to concentrations of 10.0, 5.0, 2.5, and 1.25 µL/L air for 24 hours to evaluate the lethal concentration (LC) values. Gas Chromatography-Mass Spectrometry for GO identified diallyl trisulfide (38.78%), allyl methyl trisulfide (23.93%), and diallyl disulfide (13.66%) as the main compounds. Dynamic light scattering and transmission electron microscope tests verified the stability and uniformity of the produced nanoparticles, which were distinguished by their small particle size (15.10 nm), low PDI value (0.31), and negative zeta potential (-10.20). A high encapsulation efficiency of 84.74 ± 1.74% was achieved for the produced nanoparticles. The linkage and interaction between GO and GA as a polymer were confirmed by Fourier transform infrared spectroscopy. After 24-hour exposure, GO-GA NPs resulted in lower LC50 values (1.14 µL/L air) than GO (2.08 µL/L air) against C. maculatus adults. The inclusion of GO-GA NPs at LC40 had a significant post-effect on progeny production of C. maculatus, resulting in a significant reduction in the number of deposited eggs and adult emergence, which led to a significant decrease in the percentage of adult emergence to 15.23 ± 5.46 compared to 61.33 ± 2.94, as observed in the GO treatment. GO-GA NPs enhanced the persistence activity, exhibiting a continued toxic effect for >30 days, with a PT50 of 22.29 days compared to 12.79 days for GO. This study suggested that nano-formulation could enhance the efficiency of garlic oil as an eco-friendly grain protectant to control C. maculatus adults.
