  1. The rates of infection, dissemination, and transmission for each of the three mosquito colonies exposed to GETV are contrasted in this table. The data demonstrate the three mosquitoes' suitability as prospective GETV vectors, with Cx. tritaeniorhynchus in particular displaying increasing vulnerability to GETV transmission over time (between 5 and 15 dpi). The ratio of positive females to the total number of females examined is shown by the numbers in parenthesis.
  2. *For a given parameter, colonies marked with an asterisk differ significantly at P < 0.005 according to the Chi-squared test with Bonferroni correction
