FIGURE 3.

The density of Buchnera and its relationship with facultative symbionts. The Buchnera copy numbers in one microliter of aphid DNA were show in a. (Hamiltonella‐infected aphids (Infect‐Ham.) vs. uninfected aphids (Un‐infect‐Ham.)), b. (Arsenophonus‐infected individuals (Infect‐Arse.) vs. uninfected individuals (Un‐infect‐Arse.)), c. (Serratia‐infected individuals (Infect‐Serr.) vs. uninfected individuals (Uninfect‐Serr.)), scatter dot plot with mean ± standard deviation. **p < .01 and N.S = no significant difference, data were analysis by Mann–Whitney U test. The correlation between copy numbers of Buchnera and Hamiltonella (d), Arsenophonus (e), and Serratia (f) were test according to bacteria copy numbers in one microliter of aphid DNA
