Laboratory evaluation of plant powders against the maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae), in stored sorghum.
Article in PloS one, 2026. 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
Sorghum, (Sorghum bicolor L. Moench) one of the oldest cultivated cereals and a major staple food for millions of people in many tropical and subtropical regions, is highly vulnerable to postharvest losses caused by storage pests such as the maize weevil, Sitophilus zeamais Motschulsk. Although the insecticidal effects of several botanical powders against S. zeamais have been previously reported, evidences specific to stored sorghum remains limited. The present study confirmed and comparatively evaluated the insecticidal efficacy of three plant-based powders: Phytolacca dodecandra L'Her, Nicotiana tabacum L., and Millettia ferruginea Hochst. against adult maize weevils under laboratory conditions. Treatments were applied with varying concentrations (0.4, 0.6, 0.8 and 1.0g/100g) of each botanical powder, while untreated and 5% malathion dust were used as controls. Adult mortality, progeny emergence, grain damage, and weight losses were recorded over a 15 day period. Results showed that P. dodecandra caused the highest adult mortality (96.6 ± 5.7), followed by N. tabacum (83.3 ± 0.0), and M. ferruginea (53.3 ± 3.8). All botanicals powder significantly reduced grain damage, and weight loss compared to the untreated control. These findings confirm the effectiveness of these botanicals in stored sorghum and highlight their potential relevance as locally available, eco-friendly alternatives to synthetic insecticides in Ethiopian postharvest pest management. Further research is needed under farm-level storage conditions to validate their practical applicability.
