  1. Control mosquitoes were exposed to untreated nets, and PPF treated were exposed to PPF-treated nets at 24 h prior, 6 h prior, immediately before, or 24 h post the first blood feeding opportunity, respectively. The number of mosquitoes offered a blood meal (Total) was recorded at the first blood feed, and the number of females that took a blood meal were recorded at each blood feeding. An error in recording resulted in missing data for the immediately prior cohort (ND = not determined)
