New structure in cell puncture activities by aphid stylets: a dual-mode EPG study [PDF]

open access: yes, 2010
Intracellular punctures by aphid stylets appear as potential drop (pd) waveforms in DC electrical penetration graph (EPG) recordings. We used a dual-EPG device that recorded in one channel the ‘full EPG’ with R-plus emf-components (i.e., the usual DC EPG)
