From: Behavioural and electrophysiological responses of Philaenus spumarius to odours from conspecifics
Electroantennography (EAG) responses (mean mV ± SE) of unmated P. spumarius males (grey bars) and females (black bars) to different doses of the stimuli. Stimuli consisted of headspace extracts of 15 unmated females (a) or males (b), or of body wash extracts of 8 unmated females (c) or males (d), or of extracts of head (e) or thorax and abdomen (f) of unmated females. Male and female mean EAG responses at the doses tested were compared by LMM for repeated measures, eventually followed by multiple comparisons procedure. Sex × dose interaction was never significant. Body washes of unmated females or males and head extract of unmated females elicited higher EAG response in males compared to females. Additionally, there was a positive dose–response effect to body washes of unmated females, with lower response at 10 μL compared to response at 80 μL.
