Mean EAG amplitudes (± SE) from female An. stephensi antennae. EAGs were in response to 1-octen-3-ol from both behaviourally responsive and non-responsive mosquitoes that had or had not been exposed to B. bassiana or M. acridum spores. UnExp = unexposed to fungus, Exp = exposed to fungus. R = behavioural responders in feeding stimulus assay, NR = behavioural non-responders in feeding stimulus assay. Data are grouped by days according to the earlier and later time-periods in which behavioural changes in responsiveness began to occur (See Figure 1): A) B. bassiana exposure experiment, in which recordings were made from 1 to 3 days after fungus exposure, B) B. bassiana exposure experiment, in which recordings were made from 4 to 7 days after fungus exposure, C) M. acridum exposure experiment, in which recordings were made from 1 to 7 days after fungus exposure, D) M. acridum exposure experiment, in which recordings were made from 9 to 13 days after fungus exposure Within each grouping, treatments having no letters in common are significantly different (Tukey-Kramer adjustment, α = 0.05).
