Extended Data Table 1: Logistic regression coefficients of phylogenetic signal in pest sharing among plant hosts

Table 1
  1. Parameters (median, lower and upper 95% confidence intervals) estimated for a model relating the probability of sharing a pest between two hosts to the phylogenetic distance between the hosts. The model of susceptibility (S, probability the pest will cause disease or damage on the target host) is logit(S) = β0 + β1 × log10(PD + 1), where PD is the phylogenetic distance (time of independent evolution, in Myr) between the source and target host genera. Phylogenetic distances are calculated from the updated phylogenetic tree R2G2_20140601 (Supplementary Information). Data are from 1,670 pests on 210 angiosperm plant genera in the US Department of Agriculture Global Pest and Pathogen Database. Analyses labelled ‘only polyphagous’ excluded pests only recorded from one host genus. Confidence intervals are from 1,000 runs of analysis in which a different host was randomly selected as the ‘source’ host for each pest. Predicted curves are shown in Extended Data Fig. 2.
