Experiment 1: Competitiveness of <i>w</i>Mel infected vs. uninfected males.

<p>Data pooled for all females of a certain treatment a) Percentage of viable eggs for females of compatible controls (n = 60 females), incompatible controls (n = 48 females), experimental tents (n = 161 females) and semi-field cages (n = 57 females). Numbers on bottom and top of figure represent the number of overlapping data points with extreme values (0% and 100% respectively) The dashed line represent the threshold for scoring females as viable (≥50%) or non-viable (<50%). b) Percentage of viable and non-viable females in each of the above treatments. Asterisks represent significance level for deviation from 1∶1 using observed vs. expected chi square test with each tent/cage as a repetition (see text).
