Figure 1. The impact of long lasting insecticide treated nets (LLINs) upon malaria vector population parameters.

Figure 1

Malaria vector population parameters, transmission intensity, and the impact of personal protection interventions upon them under a range of values for the proportion of blood meals obtained from humans Inline graphic. In all panels, the x-axis is the proportion of all blood meals the vector population would obtain from humans in the absence of netsInline graphic. Low values of Inline graphic represent mosquitoes that primarily feed on animals while high values represent mosquitoes that prefer to feed on humans. The y-axis for panel A represents the absolute entomological inoculation rate (Inline graphic) for an average community member in a given scenario Inline graphic. The y-axes for all other panels represents relative values for mosquito population parameters, compared with those expected in the absence of LLINs: B: Relative exposure for non-users, Inline graphic C: Relative proportion of blood-meals taken from human Inline graphic, D: Relative probability of surviving one complete feeding cycle Inline graphic, E: Relative feeding cycle length Inline graphic, and F: Relative emergence rate of adult mosquitoes Inline graphic. In all cases the intervention scenario Inline graphic crude demographic coverage specified high levels of coverage Inline graphic and use at times when transmission would otherwise occur Inline graphic.
