Modeling the Effects of Integrating Larval Habitat Source Reduction and Insecticide Treated Nets for Malaria Control (original) (raw)
Figure 3
Influence of mosquito search ability on critical thresholds for the persistence of malaria.
Letting R0 and Rc respectively denote the reproductive number in the absence and presence of control, the three parameter spaces are represented thusly: red (_Rc_>R0, worse than no control), white (Rc<R0, suppression but not elimination) and gray (Rc<1, elimination of malaria transmission). Results are shown for a range of resource-locating abilities of the mosquito: 1,000 sq m per day (in a, b and c), 2,000 sq m per day (in d, e and f) and 3,000 sq m per day (in g, h and i). Human density values used in the simulation were: ‘Low’ (100 per sq Km in a, d and g), ‘Medium’ (333 per sq Km in b, e and h) and ‘High’ (1,000 per sq Km in c, f and i). Larval habitat density is maintained at 1,000 per sq Km.
