  1. Weighted mean probabilities for the different pathways and months of emergence of Culicoides given exophilic and endophilic behaviour. Mean probabilities for the different months for pathway II were zero, and therefore are not shown in the table.
  2. NA: Not applicable (in pathways Ia and IIIa the vectors have to get infected before the start of the PLVA and therefore only apply to vectors emerged before the start of the PLVA, i.e. December)
