Table 3 Crude estimates of the costs per sampling scheme per trap-night and per Anopheles funestus caught for the three months when community-based sampling was validated with quality assurance sampling schemes

  1. aCost estimates were based on the approximated time and efforts spent on each trapping method.
  2. bAssumptions made on the salaries paid and per diem to the central level teams during their visits.
  3. cEstimated cost incurred for maintaining the equipment for transporting or visiting the trapping schemes per location.
  4. dMonthly depreciation costs calculated when both trapping schemes where operational for three months.
  5. $- US dollar.
  6. ZMW - Zambian Kwacha.
