  1. Estimates of the proportion of mosquitoes caught when most people are indoors (Pfl) and the proportion of human exposure occurring indoors (πi) were calculated based on mosquito numbers collected during times when most people are indoors (21.00–05.00)
  2. The p values listed are tests of the comparison of the estimates obtained from the electrocuting traps and those from the HLC (as the reference trap)
