Fig 6. The effect of horizontal transmission on the spread of Wolbachia through populations.

Fig 6

Simulations were performed to explore the effect of horizontal transmission on the prevalence of Wolbachia. The blue lines are where there was no horizontal transmission (w = 0), the dashed orange line was a low rate (w = 0.01), and the solid orange line a moderate rate of horizontal transmission (w = 0.06). A: The effect of horizontal transmission when there is not effect of Wolbachia on host fitness and no reproductive manipulation (H = 1, F = 1). B: Wolbachia induces cytoplasmic incompatibility (H = 0.1, F = 1). C: Wolbachia carries a fitness benefit (H = 1, F = 1.05). In all cases the starting prevalence was p = 0.01 and the rate of imperfect maternal transmission was μ = 0.03.
