Figure 2From: Modelling knowlesi malaria transmission in humans: vector preference and host competenceFitness boundary of the proportion of bites on humans by a novel vector necessary to exclude the resident vector. Novel vectors need to achieve a threshold level of bites on humans (at least 40%) in order to evolve (invade). Fitness is determined from equation 12 and represents the per capita growth rate of the novel vector strategy in the presence of alternative vectors and hosts when at equilibrium.Back to article page
