Distinct effects of two dominant enteric bacteria on the developmental performance of spodoptera frugiperda and their association with physiological metabolism.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Enteric bacteria can play an important role in the developmental performance of their insect hosts. The present study revealed that two dominant enteric bacteria, Enterococcus mundtii and Enterococcus casseliflavus, are present in the gut of Spodoptera frugiperda larvae on different host plants (maize and rice). However, the role of the two dominant bacteria in S. frugiperda remains poorly understood. To clarify the functions of E. mundtii and E. casseliflavus, the effects on the growth and development of S. frugiperda were studied by separately adding them to an artificial diet with different proportions of yeast. To elucidate the physiological metabolism underlying the differential effects of these two enteric bacteria on the developmental performance of S. frugiperda, transcriptome sequencing was conducted. The results showed that under a rich diet (with 1.85% yeast extract), E. casseliflavus significantly inhibited larval growth and prolonged the pupal stage, under a poor diet (without yeast extract), larval survival rates decreased, but larval body weight increased, and pupal weight significantly increased. However, E. mundtii had no significant effect on S. frugiperda fed a nutritionally rich diet or poor diet. These results indicate that E. casseliflavus exerts a nutrient-dependent effect on life history traits, while E. munditi has little significant impact on the developmental performance of S. frugiperda. Transcriptome sequencing analysis of differential gene expression revealed significant suppression of genes related to physiological metabolism and carbohydrate transport in E. casseliflavus. For instance, the downregulation of UDP-glycosyltransferase (UGT) and amino acid genes is closely associated with the growth and development of Spodoptera frugiperda.These findings provide deeper insights into its impact on the growth and development of S. frugiperda.
