In recent work, it was shown that the graminoid plants <i>Cynodon dactylon</i> (<i>Poaceae</i>), <i>Cyperus exaltatus</i> (<i>Cyperaceae</i>), and <i>Panicum repens</i> (<i>Poaceae</i>) have an ovipositional effect on the malaria vector <i>Anopheles gambiae</i> in olfactometric bioassays. In order to get a view of the diversity of semiochemicals present in the environment of the vector during olfactometric trials, in the present work, the volatile profiles of these graminoid plants were analyzed using headspace solid-phase microextraction (HS-SPME) together with gas chromatography–mass spectrometry (GC-MS). In addition, one-way ANOVA comparison of compounds detected in two or more headspace samples are presented in order to provide a basis for comparison of compounds that could constitute a starting point for novel blends of volatile organic compounds to be tested as oviposition attractants.
