Table 2 Maximum likelihood estimates of levels of Wolbachia infection in Lepidoptera

From: Wolbachia in butterflies and moths: geographic structure in infection frequency

Taxonomic group Method Mean prevalence, μ Incidence, x 0.001
Lepidoptera Complete database; beta distribution (eq. 3) 0.28 (0.25, 0.31) 0.84 (0.77, 0.90)
  Complete database; doubly inflated distribution (eq. 4) 0.27 (0.24, 0.31) 0.77 (0.63, 1.00)
Papilionoidea Complete database; beta distribution 0.26 (0.23, 0.29) 0.81 (0.72, 0.88)
  Complete database; doubly inflated distribution 0.25 (0.22, 0.29) 0.88 (0.65, 0.95)
  Multiple primers; beta distribution 0.32 (0.25, 0.40) 0.86 (0.72, 0.98)
  1. Estimates are shown for the mean proportion of each population that is infected (mean prevalence), and the proportion of populations with more than 1/1000 individuals infected (incidence). Each estimate was obtained by fitting a distribution of prevalences to the screen data (see text for full details)
