Table 3 Cohort life tables for Plasmodium vivax developing within Anopheles mosquitoes. Stage-specific densities and mortality coefficients (k-values) for each cohort are given, where:k-1 = log10(macrogametocyte) - log10(round stage);k-2 = log10(round stage) - log10(ookinete);k-3 = log10(ookinete) - log10(oocyst);K =k-1 +k-2 +k-3. Values in parentheses = antilogs of averaged k-values. For each Anopheles species, parasite values are ranked in descending order of macrogametocyte densities within the HIGH and LOW categories of infection intensity.

  1. * Not calculated because round stages were obviously under-sampled (note corresponding ookinete densities). Corresponding k-2 mortalities were therefore calculated as log10(macrogametocyte) – log10 (ookinete).
  2. † ND = not determined due to insufficient numbers of mosquitoes available.
