Females used in this study were all 3∼4 days old; Egg hatch was shown as mean ± standard error;

**indicates P<0.01. The same as in Table 2.

Abbreviations: Dmel wMel, Drosophila melanogaster infected with wMel; Dmel wAu, Drosophila melanogaster infected with wAu; Dmel T, Drosophila melanogaster treated with tetracycline (without Wolbachia).
