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