From eggs to guts: Symbiotic association of Sodalis nezarae sp. nov. with the Southern green shield bug Nezara viridula.
Article in FEMS microbiology ecology, 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
Phytophagous insects engage in symbiotic relationships with bacteria that contribute to digestion, nutrient supplementation, and development of the host. The analysis of shield bug microbiomes has been mainly focused on the gut intestinal tract predominantly colonized by Pantoea symbionts and other microbial community members in the gut or other organs have hardly been investigated. In this study, we reveal that the Southern green shield bug Nezara viridula harbours a Sodalis symbiont in several organs, with a notable prevalence in salivary glands, and anterior regions of the midgut. Removing external egg microbiota via sterilization profoundly impacted insect viability but did not disrupt the vertical transmission of Sodalis and Pantoea symbionts. Based on the dominance of Sodalis in testes, we deduce that N. viridula males could be involved in symbiont vertical transmission. Genomic analyses comparing Sodalis species revealed that Sodalis sp. Nvir shares characteristics with both free-living and obligate insect-associated Sodalis spp. Sodalis sp. Nvir also displays genome instability typical of endosymbiont lineages, which suggests ongoing speciation to an obligate endosymbiont. Together, our study reveals that shield bugs harbour unrecognized symbionts that might be paternally transmitted.
