Note: Two populations were sampled in the native area (Z1 and Z2), six in the European invaded area (X1 to X3 and Y1 to Y3) and two populations originated from commercial biocontrol stocks (W1 and W2). For the European invasive populations, samples were collected along two transects starting from the outbreak core and ending near the invasion front (see Figure 3). N/A – not assessed.
