Occurrence of waveform patterns demonstrating EPG-recorded stylet penetration activities of Acyrthosiphon pisum on Pisum sativum non-treated (n = 23) and treated with 0.1% apigenin (n = 17), daidzein (n = 18), genistein (n = 16) and kaempferol (n = 15): (a) frequency of occurrence of E (phloem phase), G (xylem phase), and F (derailed stylet activities) expressed as percentage of aphids that showed given activity; (b) percentage of time assigned to non-probing ‘np’ and probing activities (pathway C, activity F, xylem phase G and phloem phase E = phloem salivation E1 + phloem sap ingestion E2) Figure 2b is based on data presented in Table 1.
