What is Electrical penetration graphs from Cicadulina mbila on maize, the fine structure of its stylet pathways and consequences for virus transmission efficiency about?
## Abstract Five distinct electrical penetration graph waveforms characterising the feeding behaviour of the leafhopper __Cicadulina mbila__ Naudé (Homoptera: Cicadellidae) on maize (__Zea mays__ L.) were obtained using a DC based system. The waveforms were distinguished by spectral features and by statistical analysis of their median voltages, durations and time to first waveform recording. By changing the polarity of the system voltage and the level of the input resistor it was shown that the waveforms are mainly determined by the electromotive force (emf) component. Based on the correlation between waveforms and the fine structure of the stylet pathways observed by transmission electron microscopy, insect's activities have been associated with five waveforms: stylet pathway formation (waveform 1), active ingestion (waveform 2), putative stylet work (waveform 3), salivation (waveform 4) and passive ingestion (waveform 5). Like waveform E1 and E2 of aphids, waveforms 4 and 5 of __C. mbila__ correspond to feeding activities in sieve tubes. However, unlike aphids which probe briefly in non‐vascular cells, waveform 2 corresponds to active ingestion in cells, where the cell content is
