Probing behavior of Adelges laricis Vallot (Hemiptera: Adelgidae) on Larix decidua Mill: Description and analysis of EPG waveforms
Fig 2
Pathway phase ‘AC’ waveforms generated by Adelges laricis during EPG-recorded probing on Larix decidua.
(A) Compressed view of AC waveforms; arrows show the transition points; 100 s trace 2.5V resolution. (B) Non-probing and the transition to waveform AC1(arrow); 60 s trace, 2.5V resolution. (C) Waveform AC2; arrows indicate the beginning and the end of ‘short Apd1’ series; 100 s trace, 2.5V resolution. (D) ‘Short’ potential drops Apd1 –detail; 30 s trace, 2.5V resolution. (E) ‘Standard aphid-like’ potential drop Apd2; phases of Apd2 − I, II, III; sub-phases of Apd2 − II-1, II-2, II-3; 30 s trace, 2.5V resolution. (F) Waveform AC3, 100 s trace, 2.5V resolution.
