Figure 4. Representative GC-EAD profiles using wild caught adult female Ae. mcintoshi to the different host odors.

(A) Cow (B) Donkey (C) Human (D) Goat (E) Sheep. Upper traces are FID (chemical profile) of the respective host odor and lower traces are EAD responses. Regardless of host type, similar responses to the four aldehydes (whose peaks are labeled in the uppermost trace) were reproducibly recorded not only in this species but in Ae. ochraceus and diverse species of Culex and Mansonia which are secondary RVFV vectors (n = 3). (Scale bar in all the GC-EAD runs, 1 mV.)
