Comparison of the stroke volume and ejection volume ratio between Ae. togoi and An. sinensis.
The stroke volume was obtained by dividing the average flow rate by the pumping frequency. The average flow rates in the intake and the ejection stages, as well as the pumping frequency, were obtained from the flow rates of the two mosquito species. The results are shown in inset. Error bars represent the standard deviation; *P < 0.05, **P < 0.01.
