Fig. 5.
The impact of regeneration time on estimation of ITN wash resistance. The graphic describes what happens when a net is washed with shorter time interval (orange) than the real regeneration time (blue). Time to maximum regeneration (plateau of mosquito mortality) is 1 day whereas time to real regeneration (maximum bioavailable surface concentration of active ingredient (AI) is 4 days. On the Y axis we have an expression for amount of insecticide on the yarn surface. The 16 washes with 1-day interval removes approximately the same as 4 washes at the right interval
