Fig. 4.

Combinatorial coding of odors in An. gambiae larvae. Filled circles represent the maximal response for each AgOR. Checkered circles represent 80–99% of the maximal response of given AgOR. Horizontally striped circles represent 60–79% of the maximal response of given AgOR. Vertically striped circles represent 40–59% of the maximal response of given AgOR. Cross-hatched circles represent 20–39% of the maximal response of given AgOR. Odorants are classified into different categories according to their functional groups (aromatics, heterocyclics, esters, ketones, alcohols, and acids). The odorants highlighted in bold were also evaluated in behavioral assays.
