Fitness measurements of normal and symbiont-replaced plataspid stinkbugs. (a) Symbiont titre acquired by newborn nymphs, in terms of symbiont groE gene copies per insect. (b) Adult emergence rate (%). (c) Growth rate, in terms of nymphal period (days). (d) Adult body size, in terms of thorax width (mm). (e) Total number of eggs produced by an adult female. (f) Fertilization rate of eggs (%). (g) Hatch rate of eggs (%). Means and standard deviations are shown. Sample sizes are indicated on columns. Statistically significant differences between control treatment and symbiont-replacing treatment are shown in red.
