Proportion of the winged morph in the Regiella-free (A,C,E) and Regiella-infected (B,D,F) lines treated with antibiotics and exposed to 25 °C (A,B), 28 °C (C,D) and 31 °C (E,F) with different population densities. Regiella-infected lines: R1, R2 and R3. Regiella-free lines: N1, N2 and N3. Symbiont-cured lines treated with antibiotics: R1-C, R2-C, R3-C, N1-C, N2-C and N3-C. ** and * above the bars indicate significant differences between the antibiotic treatment and control at P = 0.01 and 0.05 levels, respectively. ns indicates no significant differences at the P = 0.05 level.
