title: Relations between Whitefly and Sweetpotato Tissue in Transmission of Yellow Dwarf Virus.
abstract: One approach revealed the nature of the piercing-sucking-feeding mechanism of the abutilon whitefly, Trialeurodes abutilonea, a new vector of sweetpotato yellow dwarf virus. It showed the complete stylet from its origin in the rostrum to its termination in the plant's translocation stream. Another approach clearly delineated and confirmed the life cycle of the abutilon whitefly in relation to physical function and duration of each of the six stages.
