Efficacy of a Mosaic Long-Lasting Insecticide Net, PermaNet 3.0, against Wild Populations of Culex quinquefasciatus in Experimental Huts in Togo

Table 3

Resistance to washing before field testing. After all washes were completed (February 10, 2008), nets were tested before being installed in experimental huts (Table 3). All treated nets were fully effective in terms of knockdown effect and mortality except PermaNet 2.0 washed 20 times ( ). Knockdown and mortality were recorded at 10 minutes interval using WHO cones, after washing and before field testing, after 3 min exposure of susceptible reference strain of An.  gambiae (Kisumu strain).
