Developmental transcriptomics reveals stage-specific immune gene expression profiles in Spodoptera frugiperda.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The fall armyworm, Spodoptera frugiperda, a globally invasive pest, demonstrates distinct immune adaptations across developmental stages and sexes, which are critical for its survival and adaptability. Using high-throughput RNA sequencing, this study systematically profiled 56 immune-related gene families, identifying 157 genes involved in Toll and Imd signaling pathways, and 185 genes associated with cellular immunity. Dynamic expression patterns were observed, with humoral immunity indices peaking during the third (L3) and fifth (L5) instars and diminishing in the pupal (P) and egg stages. In contrast, cellular immunity indices were highest in pupae and adult females, while the sixth instar (L6) and adult males exhibited the lowest immune capacity. Female adults displayed superior immune potential compared to males, reflecting evolutionary pressures tied to reproductive fitness. Notably, larval stages exhibited heightened immune gene expression, which aligns with their vulnerability to pathogens. Validation via qRT-PCR confirmed these transcriptomic trends, highlighting the modulation of immunity throughout development. These findings offer novel insights into the interplay between developmental progression and immune regulation in S. frugiperda. By elucidating these stage-specific immune responses, this study provides a robust framework for developing targeted pest management strategies aimed at mitigating the impact of this destructive pest.
