Impact of Cassava Cultivars on Stylet Penetration Behavior and Settling of <i>Bemisia tabaci</i> Gennadius (Hemiptera: Aleyrodidae).

ABSTRACT: This study investigates the settling preferences and feeding behavior of the Bemisia tabaci whitefly on six cassava cultivars using electrical penetration graph techniques. Six distinct electrical penetration graph waveforms-non-probing, stylet pathway, phloem salivation, phloem ingestion, intracellular puncture, and xylem feeding-were identified and analyzed. Significant differences in the frequency and duration of these waveforms were observed among the cassava cultivars. The whiteflies spent the majority of their time in the non-probing phase, particularly on the Huaybong 80, Kasetsart 50, Rayong 9, and Rayong 72 cultivars. CMR-89 cultivar exhibited higher total probe durations in the phloem salivation and ingestion waveforms, suggesting a greater potential for transmission of th
