Sensitivity test of the predicted adult mosquito population to the model parameter representing treatment effectiveness in the absence of the WNV infection in the model.

<p>Contour plot of the adult mosquito populations as a function of the treatment effectiveness (<i>s</i>) versus time. The remaining parameters were fixed and chosen from the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0108452#pone-0108452-t003" target="_blank">Tables 3</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0108452#pone-0108452-t004" target="_blank">4</a> (best-fit parameter values are taken for the year 2006 from Sams Point trap location).
