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

Table 4

Resistance to washing after field testing. After the end of the field trial (March 29, 2008), nets collected from huts were tested. Results yielded knockdown and mortality rates almost similar to those recorded immediately after washing and before testing. Knockdown and mortality were recorded at 10 minutes interval using WHO cones, after washing and after field testing, after 3 min exposure of susceptible reference strain of An.  gambiae (Kisumu strain).
