1Data are aggregated by species or family. The relative reservoir potential (RRP) indices sum up to 1 in both cases.
2Excludes recaptured individuals and those for whom there was missing data in the variables included in the infestation model.
3 Rates adjusted according to predictions of the number of feeding larvae for Julian day 200 of each sampling year, based on negative binomial GLMMs models of host infestation.
4Weighted means of results from larvae tested individually and pools of unfed larvae.
