Figure 2.

The recorded (green lines) and predicted (dashed lines) frequencies for the rph2 resistance allele across seven generations for (a) no selection treatment, low migration rate; (b) no selection treatment, high migration rate; (c) selection treatment, low migration rate; and (d) selection treatment, high migration rate. Black hollow squares represent initial predictions in which immigrant resistant females do not re‐mate within the population in which they establish and that only strongly resistant eggs and gametes survive fumigation within resistant females, with black hollow diamonds representing post hoc predictions in which the immigrant resistant females re‐mate after immigration, and that all gametes and eggs inside resistant females survive fumigation
