Explaining the Green-Bellied Stink Bugs Diceraeus spp. Booming in the Neotropics: Changing from a Secondary to a Key Pest Status.
Review in Neotropical entomology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The green-bellied stink bugs Diceraeus furcatus (F.) and Diceraeus melacanthus (Dallas) (Hemiptera: Heteroptera: Pentatomidae) were traditionally known as secondary pests of crops in the Neotropics. This situation has changed dramatically, and nowadays, they turned to be key pests of major commodities, such as soybean and maize. They are polyphagous, showing preference for Fabaceae (Leguminosae) and Poaceae (Gramineae). Despite being predominantly seed feeders (soybean bearing pods and cereals bearing seedheads), they also feed on vegetative (seedlings of maize, wheat, and other cultivated spring cereals) plant stages. Feeding activity includes ingestion from xylem vessels, parenchyma cells, and endosperm tissues. Feeding strategies consist on salivary sheath strategy on xylem, laceration (mechanical action by stylets, mostly mandible indentations), and maceration (chemical action of enzymes) causing cells rupture on the parenchyma and seed endosperm. Resulting damage on seedlings of Poaceae includes emission of excess tillering, whitish spots on leaves, wrinkled leaf areas, and tissue necrosis. Feeding during booming causes discolored and deformed seedheads. Fabaceae damage on the seed endosperm shows whitish spots and seed deformation. The uncommon exploration of seedlings by these seed feeding stink bugs, which result in heavy damage, occurs in order to seek for water to get hydrated; acquisition of some nutrients; and achievement of nutrients balance by diluting the concentrated in nutrients sieve from the seed endosperm they usually feed on. Understanding those feeding behaviors allows to establish some important management recommendations such as reducing soybean seed losses and weeds presence at harvest. Seeds on the ground and presence of green weeds are crucial food sources for the green-bellied stink bugs, keeping them active from first to second crop season in the field, favoring their outbreaks.
