Fig. 1From: Acaricidal activity of Cinnamomum cassia (Chinese cinnamon) against the tick Haemaphysalis longicornis is linked to its content of (E)-cinnamaldehydeConcentration–response curves of Haemaphysalis longicornis larvae. Solid lines represent the estimated mean. Dotted lines represent 95% confidence intervals (CI; lower and upper) around the mean.
