Geographic distribution of genetic clusters in Poland as defined by K = 4 STRUCTURE simulation. Each circle represents a given cohort as in Fig. 3 (k = 4 simulation). Each section shows the percentage of larvae assigned to a specific cluster by a Q value ≥ 0.70; the grey sector represents the percentage of admixed individuals. Red stars represent the two pig outbreaks. The rectangle encloses the cohorts collected from outbreak 1
