Figure 2From: Fresh, dried or smoked? repellent properties of volatiles emitted from ethnomedicinal plant leaves against malaria and yellow fever vectors in EthiopiaControl experiments for the two choice landing assay with the humanised membrane. (a) Rate of attraction of twenty female mosquitoes (Aedes aegypti) becomes constant after 4 min of exposure to untreated humanised membranes. The number of Ae. aegypti (b) and Anopheles arabiensis (c) females landing in the two-choice assay on membranes both humanised by different test subjects varies minimally. The number of Ae. aegypti females landing in the two-choice assay on membranes, one humanised by test subject A and the other by either test subject B or C, does not significantly differ between treatments (d). The number of Ae. aegypti and An. arabiensis females landing in the two-choice assay on membranes both humanised by test subject A (e). The rate of landing on membranes humanised by test subject A remains constant from 4 min to 14 min after both species of mosquitoes have been exposed to the membranes (f).Back to article page
