FIGURE 4.

Heat maps of the relative abundances and distributions of bacterial genera in housefly larvae. The heatmap illustrates the relative percentage of each genus in each sample. The color code indicates the relative abundance, ranging from faint (low abundance) to intense (high abundance). Each treatment included three biological replicates. Wa, Ya, Yb, Yc, Yd, and Ye represent housefly larvae samples fed diets with sterile water, P. aeruginosa stock solution, and the stock solution diluted 10², 10⁴, 10⁶, and 10⁸ fold, respectively.
