Disclaimer: Data points were taken from published literature (see reference list). Additional data for Italy were kindly provided by Iacucci, A., Sapienza University of Rome, Italy and  RRAC, CropLife International, Brussels, Belgium and Jones, C., University of Reading, UK. Geographical co-ordinates were rounded to a level of uncertainty, which does not allow to conclude on addresses with confirmed resistance on the map. The center of a coloured resistance spot deviates by minimum 2km from the site of resistance sampling.
