Abundance of different gut microbial taxa observed in the four groups using linear discriminant analysis effect size (LEfSe analysis). (a) Bacterial taxa with linear discriminant analysis (LDA) score greater than four in the gut microbiota of Hyphantria cunea feeding on different host plants; (b) Cladogram of bacterial biomarkers, from the phylum (innermost ring) to species (outermost ring) level, with an LDA score > 4. Differential bacterial taxa are marked by lowercase letters. Each small circle at different taxonomic levels represents a taxon at that level and the diameter of the circle is proportional to the relative abundance. Different colours represent different groups and nodes with different colours represent the communities that play an important role in the group represented by the colour.
