Median values obtained from harmonic oscillator fits for female and male Ae. aegypti (AEG), Cx. quinquefasciatus (QUI) and An. gambiae (GAM) following TTX or TeNT injection (standard errors are given in brackets); these include the best frequency and tuning sharpness (Q) of the flagellum. Combined median values including both TTX and TeNT injected states are shown to present data for all males exhibiting induced self-sustained oscillations (SOs). Median values of the power gain in four injection states (after Ringer, TTX, TeNT or pymetrozine injection), as well as a value for the combined induced state (including both TTX and TeNT), are given with corresponding standard errors. Significant differences in best frequency/Q/power gain between the control (Ringer) state and any other state for a specific mosquito group are starred (repeated-measures ANOVA on ranks; *p < 0.05; **p < 0.01; ***p < 0.001). No significant differences in best frequency/Q/power gain between the TTX exposed and TeNT exposed states for a specific mosquito group were calculated (ANOVA on ranks with a significance level of p < 0.05)
