Effects of symbiont infection on host fitness and phenotype

In all of the four species, the adult emergence rate without symbiont capsules was drastically reduced in comparison to that with symbiont capsules . In M. punctatissima and M.

cribraria, about 50% of aposymbiotic nymphs died during developmental course (Figures 5 . 10A and B) . In B. subaeneus and C. parvipictum, all of the aposymbiotic nymphs died before adult emergence (Figures 5 . 10C and D) . In M. punctatissima and M. cribraria, about half of the aposymbiotic nymphs managed to become adults, but they exhibited abnormal phenotypes such as pale coloration, small body size, etc . (Figure 5 . 11) . These aposymbiotic adult insects neither copulated nor reproduced
