aIn experiment 1 Spiroplasma infection prevelance was determined using adult offspring, while in experiment 2 Spiroplasma infection prevelance was determined using pupal offspring.
bNumber of mating pairs at the beginning of each experiment. Not all mothers survived for three GCs.
cPercentage of Spiroplasma infected offspring derived from each parental mating pair over the course of all three GCs combined.
