  1. The number of mosquitoes emerged through the unit was calculated from the number of pupae placed underneath the marking device and removing the number that remained the following day
  2. aTo calculate the number marked, a correction factor of 0.86 was applied to account for the marking success of the unit as observed in previous semi-field studies
  3. bA 50:50 sex ratio of pupae is assumed to estimate the number of mosquitoes of each sex marked. An overall marking rate is given as well as data for each colour pigment for both sexes
