Patients infected with gametocytes attract anopheline mosquitoes differentially compared to healthy individuals, an effect associated with an increased release of attractive volatile cues. This odour-driven manipulation is partly mediated by the gametocyte-specific metabolite, (<jats:italic>E<\/jats:italic>)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMBPP), which induces increased release of select aldehydes and terpenes from red blood cells and results in the enhanced attraction of host-seeking mosquitoes, which are vectors of malaria. This study investigates the effect of the HMBPP-induced volatiles on the attraction of wild <jats:italic>Anopheles<\/jats:italic> mosquitoes to humans under field conditions.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The efficacy of the HMBPP-induced odour blend to attract <jats:italic>Anopheles<\/jats:italic> was evaluated in a 4\u2009\u00d7\u20096 Latin rectangular study design indoors using baited Suna traps. Furthermore, to assess the efficacy of the HMBPP-induced odour blend in (1) augmenting the attractiveness of human odour, and (2) attracting <jats:italic>Anopheles<\/jats:italic> mosquitoes in the absence of human odour, a two-choice assay using host decoy traps (HDTs) was used and evaluated using binomial generalized regression.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Traps baited with the HMBPP-induced odour blend attracted and caught both <jats:italic>Anopheles arabiensis<\/jats:italic> and <jats:italic>Anopheles pharoensis<\/jats:italic> females in a dose-dependent manner in the presence of background human odour, up to 2.5 times that of an unbaited trap. Given a choice between human odour and human odour laden with the HMBPP-induced odour blend, mosquitoes differentially preferred traps augmented with the HMBPP-induced odour blend, which caught twice as many female <jats:italic>An. arabiensis<\/jats:italic>.
