Effect of additive genetic variance on parasitism rates and resistance.

a) Proportion of parasitized and resistant weevils at 300 generations for different ratios between the additive genetic variance (AGV) of the parasitoid and the host. All parameters were kept constant, except for the parasitoid AGV. The dashed blue line and the blue arrows show resistance and parasitism rate of an asexual parasitoid interacting with a sexual host (parasitoid AGV = 0 and host AGV = 0.1). The dotted red line and the red arrows show resistance and parasitism rate of a sexual parasitoid interacting with a sexual host (parasitoid AGV = 0.1 and host AGV = 0.1). b) Examples of the parasitism rates over generation time for an asexual parasitoid (blue dashed line) and a sexual parasitoid (red dotted line).
