Table 3: Post-hoc Tukey analysis of six compounds found in the headspace samples of both the root and shoot samples of each of the three graminoid plants. compounds could be involved in both the short- and long-range attraction of the vector, suggesting their potential as \"blend-effect\" chemicals. After these blends are evaluated, the addition of individual compounds to the blend could be investigated for potential increased effect on the malaria vector. Examples of such compounds could be \(\beta\)-elemene, which was detected in _C. exaltatus_ shoot samples, or germacrene D, which was only detected in the root samples of _C. dactylon_. However, the addition of single compounds will be more of a \"hit-and-miss\" approach, although the tentative selection of compounds has been narrowed down with the results reported in this study.
