Flight tunnel behavioural assay. An. stephensi in-flight host-finding ability was assessed in the days following exposure to B. bassiana spores. On each day, ten mosquitoes from each of the fungal-exposed or unexposed groups were assessed three times for their responsiveness to the heat-plus-odour source. Mean percentage (+/- standard error) of mosquitoes flying upwind is shown. Asterisks denote fungal exposed groups having significantly lower upwind flight responses than the unexposed group within a given day using Wald chi-square tests (α = 0.05 after Bonferoni-correction).
