Fig. 2. (A-D) Schematic drawing of four morphologically distinct antennal trichoid sensilla of Ae. aegypti and (E) the approximate distribution, however, not the exact location, of their various functional types (Ghaninia et al., 2007) between the antennal segments. For the scanning electron micrograph of the sensilla, refer to Ghaninia et al. (Ghaninia et al., 2007). sst, short sharp-tipped; lst, long sharp-tipped; sbtI, short blunt-tipped I; sbtII, short blunt-tipped II; i, intermediate.
