PCoA plot based on an unweighted UniFrac distance matrix depicting differences in the composition of the gut microbiota of the five groups. In the unweighted UniFrac analysis of the gut samples, the first principal coordinate, explained 40.11% of sample variation and separated groups of LG and HLYHL from others. The third principal coordinate (7.49% of sample variation) separated groups (M) from others. Z: Tetrix japonica; ZS: Ruspolia lineosa; M: Erianthus versicolor; LG: Gryllotalpa orientalis; HLYHL: Teleogryllus emma.
