Figure 3. A) Proportion of mosquitoes infectious with LF when malaria is removed from the co-endemic equilibrium; B) the proportion of mosquitoes infectious with malaria when LF is removed from the co-endemic equilibrium.

The negative effect of LF on malaria is due to the increased mortality associated with harbouring W. bancrofti larvae, while the effect of malaria on LF is a balance between the additional death rate on humans, increasing the mosquito∶human ratio, and the Plasmodium-induced mosquito mortality.
