Evaluation of vector control strategies. Simulations showing the modelled changes in the abundance of active adult vectors when interventions with different mechanisms of action are used to control the mosquito population. Panels a, d and g show the effects of interventions that increase the larval death rate (e.g. larvicides) whilst panels b, e and h show the effects of interventions that kill adult mosquitoes (e.g. IRS, LLINs or other insecticides). Panels c, f and i show the effects of combining these two targets. Panels a-c are predicted from a model with no aestivation; d-f from a model including aestivation in which only the active vectors are targeted and g-i from the aestivation model if dormant vectors are also targeted. Parameter values used are given in Tables 1 and 2. Intervention efficacies of 0, 20 and 80% were used, and these represent percentage increase in mortality of vectors/larvae induced. The dotted line (0%) means no intervention; the red line and the black line represent interventions that increase vector/larvae mortality by 20 and 80%, respectively. See Additional file 1: Text 1 for further details on how interventions were simulated
