Fig. 9From: Controlled release spatial repellent devices (CRDs) as novel tools against malaria transmission: a semi-field study in Macha, ZambiaSimulations of protection plumes around huts using nominal release rates of metofluthrin. A Protection volume was defined using input parameters (metofluthrin release rates, environmental conditions) and simulated a prior to test initiation (1 h after devices are activated), b at test initiation (6 h after devices are activated), c at test end (18 h after devices are activated)Back to article page
