Boxplot showing the mean diameter of the zone of inhibitions (in mm) of protected egg extracts according to the microorganism on which they were tested (egg assay) and the maternal bacterial treatment.

<p>The boxes extend from the first to the third quartiles, the band inside the box represents the median. The bars outside the boxes indicate the 1.5 interquartile of the lower and upper quartiles. Each dot represents a data point, and the biggest dot represents the median. The sample size of each treatment is stated between brackets under the egg assay. Different letters above the bars indicate significant differences according to the degree of overlap of the 95CI (p < 0.05, see <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1005178#ppat.1005178.s003" target="_blank">S2 Fig</a>) across female treatments. Treatments: naïve = unmanipulated females, PBS = sham-injected females, Ag = <i>A</i>. <i>globiformis</i>, Bs = <i>B</i>. <i>subtilis</i>, Bt = <i>B</i>. <i>thuringiensis</i>, Ec = <i>E</i>. <i>coli</i>, Se = <i>S</i>. <i>entomophila</i>, Sm = S. <i>marsescens</i>. Were only represented, for all the maternal treatments, the clutch treatments on which a ZI could be detected.
