Dose–response curves for EAG responses of Chrysomela populi and Phratora vitellinae to different volatile compounds. The curves are based on the Mixed Linear Model. Dose is expressed as dilution (v/v) of the compound in hexadecane. EAG response (expressed as maximum amplitude of depolarization) is expressed in – mV. The mean absolute EAG response amplitude to hexadecane is shown by the dashed line
