The feeding activity of Sogatella furcifera (Horvath) was monitored on rice plants of susceptible 'Taichung Native l' and resistant 'IR 2035-117-3' varieties with an electronic device. Distinct differences in the waveforms for probing, salivation, and ingestion were recorded on leaf sheaths of susceptible and resistant plants. The waveforms indicated that the insect was primarily a phloem feeder on both susceptible and resistant plants, but probed readily and fed longer on the susceptible variety. In contrast, the insect made brief and repeated probes on the resistant variety, consequently reducing the effective ingestion period. The quantity of food ingested by S. furcifera was also significantly higher on the susceptible than on the resistant variety.
