  1. 1 Kruskal-Wallis test; catches from the summer months (June to September) during the 3 years monitoring.
  2. 2 Locations with high overall sampling reliability (i.e. at least 145 of the maximal 156 weekly catches available, see Table1).
  3. 3 Percentage of total Culicoides caught over the whole collecting season (June – May).
  4. * Significantly different using the Kruskal-Wallis test without Bonferroni correction (p < 0.05).
  5. Significantly different using the Kruskal-Wallis test with Bonferroni correction (p < 0.008).
