<p>(A) Fecundity was determined as a measure of eggs laid per female. Bars are the mean number of eggs laid ± SEM from >40 females (individual data points are superimposed). Symbols for tetracycline-treated mosquitoes (uninfected) are in black, <i>Wolbachia</i>-infected are in red. Asterisks indicate significance compared to Tet x Tet controls (Kruskal-Wallis, Dunn's test, * for <0.05, ** for <0.01, *** for <0.001, **** for <0.0001). (B) Hatch rates for crosses between infected and uninfected mosquitoes show CI and successful hatching. Symbol codes and statistics are as per (A). Data are the mean ± SEM from >40 females (individual data points are superimposed). (C) Eggs from gravid females were collected over 72 h, from 3-days post blood meal. Eggs were dried slowly over 3–5 days then stored in a humid, airtight container. Batches of 100–500 eggs were hatched after 1, 2, 3, 4, 6, 8, 10 and 12 weeks. Hatched larvae were counted at 2nd instar stage until no hatch was observed for a week then the percent hatch calculated. Statistical analysis was performed using 2way ANOVA Sidak's test (n = 4 at each time point). <i>w</i>Pip hatch rate was significantly reduced at all weeks compared to <i>w</i>Pip.Tet (p<0.0001). <i>w</i>Mel hatch rate was significantly reduced at weeks 4, 8, 10, (p<0.05) and 12 (p<0.0001) compared to <i>w</i>Mel.Tet. <i>w</i>MelCS had a significantly reduced hatch rate at weeks 10 and 12 compared to <i>w</i>MelCS.Tet (p<0.01 and p<0.0001, respectively). <i>w</i>Ri had a significantly reduced hatch rate at week 12 only, compared to <i>w</i>Ri.Tet (p<0.0001).</p>
