Figure 4

Histogram depicting responses from infected (solid; n = 6) and uninfected (open; n = 5) maxillary palp sensilla from female An. stephensi that were stimulated with three concentrations of R-(-)-1-octen-3-ol. Testing was carried out in a background environment of 0 ppm CO₂. There was no statistical difference between the infected and uninfected insects in the mean number of spikes generated in response to stimulation at any of the three doses (0.0001 μg, 0.001 μg and 0.01 μg) of R-(-)-1octen-3-ol. SEM is indicated for each response average. “SA” is the unstimulated spontaneous activity level as recorded at the beginning of each stimulation period.
